Welcome to Sakanotsuji Touge, a legendary mountain pass nestled in Japan’s Hyogo Prefecture. Known as a "Golden Drift Spot" from the 90s, this narrow ribbon of asphalt connects Shiso City and Kamikawa Town, carving its way around the base of Mountain Seppiko. In Assetto Corsa, it is a technical masterclass in Japanese touge, where tight hairpins and off-camber transitions demand the perfect balance of "90s style" aggression and precision.
Sakanotsuji is a versatile touge that changes its personality entirely depending on your direction and discipline, offering everything from uphill drift sessions to focused downhill time attacks.
Mountain Seppiko Pass: The core of the run. This section is the only mountain road connecting the surrounding towns, making it a high-stakes corridor. In the sim, it’s a relentless technical maze where the guardrails are close and the margin for error is razor-thin.
The 90s Golden Drift Sections: Revisit the birthplace of modern drift culture. These sectors are designed for mid-to-high angle transitions, mirroring the "autobike boom" spots where drifters first began to take over the mountain.
The S-Bend Cascades: A series of rhythm-based corners that demand perfect weight transfer. Whether you're chasing a "clean" grip line or initiating a massive slide, these cascading bends will test your car's suspension and your throttle control.
The Technical Plateau: As you approach the crest, the road levels out slightly, allowing for higher-speed entries into the final downhill plunge. It’s the perfect place to settle the car before the tires, and the brakes, really start to cook
Welcome to Irohazaka, Japan’s most technical and gravity-defying mountain pass. Located in the Nikko National Park, this legendary "Iroha Slope" is a one-way masterclass in hairpins, consisting of two separate roads that connect central Nikko to the high-altitude Lake Chūzenji. In Assetto Corsa, this track is a grueling test of patience and low-speed car control, where the pace is dictated by 48 sharp turns—each named after a character of the ancient Japanese alphabet.
The Irohazaka is a loop of two distinct roads: the Second Irohazaka for the uphill ascent and the First Irohazaka for the downhill plunge.
The First Irohazaka (Downhill): This is the iconic 28-curve descent featured in Initial D. It’s a rhythmic gauntlet of straight-hairpin-straight-hairpin, where the elevation drops 440 metres over just a few kilometres.
The 33rd Corner & "The Jump": Experience the most infamous shortcut in street racing history. At the 33rd corner (the 13th downhill hairpin), the terrain allows for the legendary "Irohazaka Jump," where mid-engined legends like the SW20 MR2 can skip sections of the track by launching off the inner ledge.
Akechidaira Plateau: The midway resting point on the uphill climb. This observation deck offers a panoramic view of the valley and the stacked hairpins you've just conquered, providing a brief moment of zen before the next set of curves.
The Three Bridges: The final sprint at the base of the mountain crosses the Daiya River three times. After the technical torture of the hairpins, these bridges allow you to finally open up the throttle and cool your brakes before finishing in central Nikko.
Welcome to Yaseone Pass, the physical gateway to the legend of Akina. Located on Gunma Prefectural Route 33 in Japan, this high-altitude pass serves as the literal starting line for the most famous downhill runs in street racing history. While the world knows the mountain as Haruna, the "Yaseone" section, specifically near the old tollgate. is the hollowed ground where the Takahashi brothers first waited for a phantom AE86. In Assetto Corsa, it acts as the high-pressure staging area before the mountain drops away into a technical nightmare.
Yaseone isn't just a pass; it’s a transition point. Situated roughly 1,170 metres above sea level, it marks the boundary between the serene caldera of Lake Haruna and the brutal descent toward Ikaho.
The Old Tollgate (The Starting Grid): The most recognizable landmark. This wide, flat section of road is the universal starting point for downhill battles. In the sim, it’s the place to check your tire pressures and clear your head before initiating the first high-speed sweeper.
The Initial D Manhole Covers: A nod to the pilgrims. In real life and high-detail mods, you’ll find custom manhole covers featuring the Initial D cast, marking this as the spiritual home of the series.
The First High-Speed Sweeper: Immediately after leaving the Yaseone parking area, the road dives into a long, banking right-hander. It’s a deceptive introduction that forces you to build massive momentum before the technical hairpins begin to stack up.
The U-Turn Point: Often used by local racers to reset their runs, this pull-off area near the summit allows for a quick turnaround to practice the uphill climb (the "Uphill" layout) or to wait for a challenger to arrive from the valley.
Welcome to Mount Akagi, the tactical home turf of the RedSuns. Located in Gunma Prefecture, this is one of the "Three Mountains of Jomo" and a cornerstone of Japanese street racing culture. While Akina is known for its hairpins, Akagi is a high-speed, technical flow that rewards calculated aggression and perfect lines. In Assetto Corsa, this track is a masterclass in mid-to-high speed weight transfer, featuring wide lanes that mask a deceptive and unforgiving complexity.
Spanning roughly 5.6 kilometres on the downhill, Akagi is a "power touge" where horsepower actually matters, provided you can keep the car balanced through its rhythmic sweepers.
The Summit Start: Beginning near the entrance to Mount Akagi Shrine and Lake Ōnuma, the run starts at an altitude of over 1,300 metres. The air is thin and the initial straights are fast, allowing you to build massive momentum before the mountain drops away.
The High-Speed Sweepers: Unlike the tight switchbacks of Irohazaka, Akagi features long, banking curves. This is where the "RedSuns style" was born—maintaining high corner entry speeds and using aerodynamic stability to outpace more agile rivals.
The "Section 3" Hairpins: Toward the bottom of the pass, the road tightens significantly. A series of consecutive hairpins tests your braking zones; overshooting here means a face-full of the red-and-white guardrails that define the Gunma scenery.
The Finish Line: The run concludes at the toll booth area at the base of the mountain. After a high-intensity descent, this wide-open finish is the ultimate place to check your sector times against the local legends.
Welcome to the Hakone Turnpike, the "Japanese Nürburgring." Located in Kanagawa Prefecture, this privately owned toll road is arguably the most prestigious stretch of asphalt in Japanese car culture. Unlike the tight, claustrophobic touge of Gunma, the Turnpike is a high-speed playground with wide lanes, sweeping bends, and a perfectly maintained surface designed for high-performance testing. In Assetto Corsa, it serves as a high-stakes cathedral of speed where JDM manufacturers develop their legends and street racers settle their ultimate scores.
Ascending over 1,000 metres from near sea level, the Turnpike offers a technical journey that transitions from dense, lush forests to high-altitude ridge runs with a constant backdrop of the Pacific coastline.
The Odawara Toll Gate: The starting line at the eastern base. This is where you pay your virtual toll and begin a steady, powerful climb through a series of medium-speed sweepers that allow you to really let your engine sing.
The Cherry Blossom Tunnel: Between the 2km and 7km markers, the road is lined with sakura trees. In many Assetto Corsa mods, this section transforms into a riot of pink blossoms, creating one of the most visually stunning driving experiences in the world.
The High-G Sweepers: As you rise above the treeline, the corners open up. This section demands high-speed stability and aerodynamic trust, as you navigate long, banking turns that overlook the sparkling Sagami Bay.
The Daikanzan Observation Deck & Sky Lounge: The summit and social hub of the mountain. Located at the highest point of the turnpike, the "Anest Iwata Sky Lounge" (formerly the Mazda Sky Lounge) offers a panoramic view of Lake Ashi and a majestic vista of Mount Fuji.
The Hakone-Kojiri Exit: The final stretch toward Lake Ashi. After the high-speed thrill of the main line, the road levels out and deposits you into the heart of Hakone’s volcanic hot spring region
Welcome to Mount Myogi, the terrifying home of the NightKids and the final peak in the "Three Mountains of Jomo." Located in Gunma Prefecture, Myogi is a jagged, volcanic giant that looks more like a row of broken teeth than a mountain. Unlike the technical hairpins of Akina or the balanced flow of Akagi, Myogi is a high-speed "power touge." In Assetto Corsa, it’s a white-knuckle test of high-speed stability and bravery, where the road is wide enough to lure you into triple-digit speeds before snapping shut into a lethal series of high-G sweepers.
Myogi is a road built for heavy hitters. It rewards cars with massive torque and high-speed downforce, but the sheer cliffs and lack of runoff mean one slip-up is terminal.
The Myogi Shrine Start: You begin your ascent (or descent) near the historic Myogi Shrine at the base of the mountain. The jagged rock formations tower over the starting line, setting a dark, aggressive tone for the run.
The High-Speed Sweepers: This is where Myogi separates the pros from the amateurs. The road consists of long, banking curves that allow for immense speed. However, the guardrails are often the only thing between you and a vertical drop, demanding absolute trust in your car’s front-end grip.
The "NightKids" Hairpins: Toward the summit, the road tightens into a few technical switchbacks. These are the primary overtaking spots where "bump and run" tactics—famously employed by the local R32 GT-Rs—can turn the tide of a battle.
The Summit Lookout: Reaching the top brings you to a massive parking area overlooking the Kanto Plain. It’s the perfect spot to cool your brakes and admire the jagged peaks before the high-speed plunge back down
Welcome to Usui Pass, the ultimate test of lateral grip and rhythm. Located on the border of Gunma and Nagano Prefectures, this legendary stretch of Route 18 is the home turf of the Impact Blue duo. Unlike the terrifying drops of Myogi or the high-speed flow of Akagi, Usui is a tight, rhythmic maze featuring an incredible 184 turns in just a few miles. In Assetto Corsa, it’s a masterclass in weight transfer, where success isn't about top speed, but about finding a seamless, dancing flow through its endless C-shaped curves.
Usui is a relentless technical gauntlet where the road never truly goes straight, forcing you into a constant state of cornering.
The C-121: The most famous corner on the pass. This high-speed, 121st turn is a massive, banking left-hander that demands a high-stakes entry. It’s the ultimate "make or break" point for any battle, nail the entry speed, and you’ll leave your opponent in the dust.
The Megane Bridge (Usui Third Viaduct): A stunning red-brick railway bridge that towers over the track. It’s the most iconic landmark on the pass, marking a technical section where the road narrows and the stone walls close in.
The 184 Turns: Because there are so many corners, Usui is all about memory and stamina. The road surface is relatively smooth, but the sheer repetition of tight turns will cook your front tires if you’re too aggressive with the steering rack.
The Nagano Border: The summit marks the transition between Gunma and Nagano. After the claustrophobic climb, the road opens up slightly, allowing for a brief high-speed sprint before you reach the highland plateau of Karuizawa
Welcome to Sadamine Pass, the soul of the Saitama touge scene. Located on Prefectural Road 11, this mountain pass is the home turf of the Northwest Saitama Alliance and a legendary proving ground for technical hillclimbing. In Assetto Corsa, Sadamine is a masterclass in varied technicality, it’s wider and smoother than the claustrophobic Shomaru, but it features a complex "staircase" rhythm of tight hairpins and medium-speed sweepers that will punish anyone who loses their focus.
Spanning roughly 5.5 kilometres of asphalt, Sadamine is a road of two halves, transitioning from a dense forest floor to an open ridge run.
The Tea House Start: The summit is home to a famous local tea house, serving as the universal staging area for both the uphill and downhill runs. It’s the spiritual hub of the pass, where racers gather to talk shop before plunging into the valley.
The Technical Switchbacks: The upper section of the pass is a relentless series of hairpins. Unlike the one-way system of Irohazaka, Sadamine is a standard two-lane road, meaning you have to nail your late apexes while respecting the center line.
The Rhythmic Sweepers: As you descend, the road opens up into a series of medium-speed flowing bends. This is where you can really let a balanced chassis like an S2000 or an MX-5 shine, maintaining a high minimum speed through the forest.
The "Bus Stop" & Finish: The run concludes near the lower transit points as the mountain levels out. After the high-intensity technical work at the summit, the final sprint is a test of who can carry the most momentum out of the trees
Welcome to Mitsuishi Forest Park (三石森林公園), a tight, technical 850-metre touge experience buried in the dense woodlands of Ibaraki, Japan. This is the epitome of grassroots Japanese drifting—a short, high-intensity ribbon of asphalt where precision is everything and there is zero room for error.
Developed by THOM_6 (MINATO) in collaboration with the Nihon Drift Project (NDP), this track perfectly captures the 'drift-until-dawn' atmosphere of Japan's mountain culture. It is a compact, rhythmic layout designed for technical practice and close-quarters tandem battles.
Tight & Technical: At just 850 metres, the course is a concentrated blast of constant elevation changes and narrow sections. Every run forces you to manage weight transfer and throttle modulation with surgical accuracy.
The Touge Spirit: This isn't a wide-open circuit; it’s a narrow mountain pass recreation that rewards those who can link slides door-to-door without touching the guardrails.
Grassroots Heritage: The layout reflects the real-world history of Japanese mountain roads that were eventually modified with anti-skid pads to deter street racing. This digital recreation preserves the route in its pure, driftable state.
10 Pit Boxes: Despite its small footprint, the map is built for community sessions, offering enough pit space for a focused group of drifters to cycle through runs and perfect their lines.
Welcome to Nagao Pass, the technical gateway between Kanagawa and Shizuoka. Straddling the north-western rim of the Hakone caldera, this mountain pass is a pilgrimage site for those who value momentum over raw power. In Assetto Corsa, Nagao is a masterclass in commitment, featuring a narrow 3-metre width that makes even the smallest street car feel like a wide-body racer. It is a road of surgical precision, famously serving as the home turf for the Katagiri Street Version team and the site of Takumi Fujiwara's high-stakes rematch with Kai Kogashiwa.
Rising to an elevation of approximately 900 metres, Nagao offers a focused driving experience that trades the wide lanes of the Turnpike for tight, foliage-lined corridors and breathtaking glimpses of Mount Fuji.
The Gotemba Tunnel: The spiritual and physical border between prefectures. Emerging from this narrow tunnel marks the transition between the high-speed approach and the technical descent, often shrouded in a thick mountain mist that hides the upcoming apexes.
The Lidless Gutters: A signature feature for Initial D fans. In many high-fidelity mods, the "lidless" sections of the drainage gutters are modeled, allowing for high-risk "gutter run" entries that can shave precious tenths off a downhill time.
The Abandoned Tea House: A haunting landmark located near the summit. This weathered building serves as a perfect visual marker for the start of the most aggressive technical sector, where the road surface becomes uneven and demands a perfectly tuned suspension.
The Hakone Skyline Interchange: The southern terminus where the tight touge opens up. After the claustrophobic intensity of the pass, this junction offers a rare high-speed sprint toward the scenic vistas of Lake Ashi.
Welcome to the Tsubaki Line, the "Holy Land" of Kanagawa and the final battlefield for Project D. Located on Mount Hakone, this high-speed descent toward the hot spring town of Yugawara is the ultimate test of high-speed technicality. In Assetto Corsa, it is a masterclass in aerodynamics and courage, featuring wide, perfectly paved lanes that invite you to push far beyond your comfort zone. This isn't just a road; it’s a high-stakes cathedral where the final scores of a racing season are settled at triple-digit speeds.
Spanning roughly 14.5 kilometres, the Tsubaki Line (Camellia Line) is a "power touge" that evolves from high-altitude sweepers into a technical hair-raising sprint.
The Daikanzan Start: You launch from the iconic observation deck under the shadow of Mount Fuji. The first sector is incredibly fast, demanding a car with high-speed stability as you dive into long, banking turns that overlook the Pacific.
The Mist-Slayer Sections: The upper mountain is notorious for thick, sudden fog. In the sim, this creates a psychological battle; you have to trust your memory of the braking zones when the next apex is swallowed by a wall of white.
The Technical Hairpins: Toward the bottom, the road tightens. These aren't the slow hairpins of Akina; they are medium-speed, high-G turns that test your suspension's ability to handle rapid weight transfer without washing out into the red-and-white barriers.
The Finish Line (The Bridge): The run concludes as the road crosses toward the Yugawara hot springs. After a 14km sprint, your brakes will be glowing, and your engine will be screaming for air—crossing this line is the ultimate relief
Welcome to the Tsukuba Fruits Line, the "Purple Shadow" of Mount Tsukuba and the ultimate test of high-speed technicality in Ibaraki Prefecture. Famous as the home turf of the legendary "God Foot" and "God Arm," this stretch of the Fruits Line is a high-stakes arena where raw power meets surgical steering. In Assetto Corsa, it’s a high-tension sprint through dense, overhanging forests, featuring four consecutive hairpins and off-camber sweepers that will punish anyone who lacks a perfectly balanced setup.
While many touges are narrow and crumbling, the Fruits Line offers a relatively wide, high-quality road surface—but don't get comfortable. The speed carried into the corners makes the margin for error just as thin as a mountain goat track.
The "God Arm" Technical Run: This sector is a tribute to the master of the one-handed steering technique. It demands smooth, continuous inputs and a car that responds to the slightest throttle lift to rotate through the flowing mid-speed bends.
The Four Consecutive Hairpins: The climax of the pass. Unlike the stacked hairpins of Akina, these are slightly more spaced out, requiring intense braking and high-torque exits to maintain your rhythm. It’s the primary "overtake or die" zone for any battle.
The Mt. Tsukuba Skyline Interchange: The high-altitude crossroads that connects the Fruits Line to the faster, more open Skyline. In the sim, this junction is the perfect place to reset your run or transition into a high-speed chase toward the summit.
The Forest Tunnels: Dense foliage often hangs over the road, creating deep shadows even during the day. Keeping your eyes on the "invisible" apexes through these dark corridors is the only way to maintain a record-breaking pace.
Welcome to Tsuchisaka Pass, the high-stakes battleground on the border of Gunma and Saitama Prefectures. Known as the home course of the notorious Lancer Evolution Team, this track is infamous for more than just its technical corners, it’s the place where "dirty racing" met its match. In Assetto Corsa, Tsuchisaka is a unique 7-kilometre challenge that offers both Inbound and Outbound layouts, featuring a peak-summit tunnel that acts as a pivot point for a punishing uphill and a technical downhill.
Tsuchisaka is a game of two halves, famously separated by a tunnel that marks the highest point of the pass.
The Inbound Gauntlet: This section features tighter corners and steeper gradients, making it a nightmare for low-horsepower cars. It’s a technical slog that rewards high-torque machines that can "dig in" on the steep exits.
The Outbound Descent: A more flowing, high-speed run that rewards smooth lines and late braking. This is where you can truly feel the weight transfer of your car as you plunge toward the base of the mountain.
The "Oil Spill" Straight: Watch your step near the entrance of the Outbound section. While the virtual track is usually clean, local lore reminds every racer of the "trap" laid here for Keisuke Takahashi’s FD, keep your eyes peeled for the slick that once changed the course of a racing season.
The Tsuchisaka Tunnel: The "summit bridge" between two worlds. Emerging from the darkness of the tunnel marks your transition between uphill struggle and downhill aggression, requiring an immediate mental shift in your driving style.
Welcome to Tsuru Country, a technical drift spot nestled in the mountains of Yamanashi Prefecture, Japan. Part of the Nihon Drift Project (NDP) series, this track is a 550-meter recreation of a section of Route 712 connecting Ohata and Hatsukari. It is a "nostalgic" touge route named after the nearby Chuo Tsuru Country Club. In Assetto Corsa, it serves as a short, atmospheric corridor designed for beginner-friendly technical drifting and tandem runs, featuring a mix of vintage asphalt and modern modernization.
Despite its short length, Tsuru Country is packed with character, recreating a specific "old-school" vibe with narrow lines and gritty textures.
The Route 712 Pass: The core of the map is a narrow, technical mountain road. It features remnants of old 1970s asphalt visible in the turns, providing a tactile sense of history as your tires fight for grip on the aged surface.
The Country Club Branch: One side of the map features a perfectly placed intersection that leads to the golf club entrance. This serves as the primary U-turn point for resetting your drift runs and staging tandem sessions.
The "Precision End": Unlike the wide country club branch, the opposite end of the playable section is significantly more narrow and unforgiving. Performing a U-turn here requires surgical steering to avoid wrecking your car against the mountain barriers.
The 1970s Modernization: The track surface varies between sections of modernized pavement and the older, cracked asphalt of the original pass, demanding constant adjustments to your car's weight transfer
Welcome to Makime Touge, a grit-filled relic of the mid-90s drift era. Tucked away in the mountains of Kanagawa Prefecture, this track is a "rare piece of history" that captures the raw, unpolished energy of underground Japanese street drifting. In Assetto Corsa, it serves as an authentic time capsule of a spot that was active in 1996, offering a driving experience that values character and "old-school back-road energy" over modern perfection.
Makime is defined by its unique surface and technical narrowness, providing a sensory experience that differs from the smooth asphalt of more modern passes.
The Patterned Concrete: The defining feature of Makime. The road consists of a unique concrete surface with a distinct patterned texture. This gives the driving feel its own unique character and feedback, challenging your tires to find grip on the textured blocks.
The 1996 Time Capsule: Most NDP versions include two variants: a modern version and a 1996 version. The '96 layout is often recommended by veterans to avoid the "bumpy" middle sections that have developed over decades of real-world neglect.
The Technical Squeeze: True to the Kanagawa style, the lines are narrow and the ambience is gritty. There are no wide run-offs here; it is a claustrophobic maze of trees and stone where a single miscalculation will send you into the scenery.
The Drift Era Flow: Based on surviving footage from the mid-90s, the track's layout is specifically tuned for the drift styles of that period. It rewards "momentum drifting" and precise throttle control rather than just high-horsepower smoke shows
Welcome to Kuragari Touge, the "Pass of Darkness." Linking Osaka and Nara via Route 308, this is not your typical high-speed mountain road, it is one of the steepest and most punishing public roads in Japan. Known for its brutal 37% gradient and ancient cobblestone sections, Kuragari is a test of low-gear torque and raw survival. In Assetto Corsa, it is a technical anomaly: a claustrophobic, vertical labyrinth that feels more like a narrow alleyway than a mountain pass.
This is "shining" (deadly) road territory. Kuragari demands a total departure from traditional racing lines in favor of careful tire placement and constant gear-hunting.
The 37% Slope: The "S-bend of hell." This section is so steep that many street cars struggle to climb it in real life. In the sim, it will test your engine's torque and your car's cooling system as you fight gravity to reach the summit.
The Ancient Cobblestones: At the very top of the pass, the asphalt vanishes, replaced by historic stone paving. This transition is a nightmare for grip, causing high-revving drift cars to bounce and skip unpredictably as they cross the Nara border.
The Resident Corridor: Much of the pass runs directly between traditional houses and stone walls. The road is so narrow that your side mirrors will practically graze the architecture, leaving zero room for "styling" or wide transitions.
The Descent of No Return: Going down the Osaka side is a test of brake fade. The incline is so extreme that relying purely on your foot brake will lead to disaster; you’ll need to master engine braking just to stay on the road.
Welcome to Kameishi Pass, a legendary stretch of the Izu Skyline in Shizuoka Prefecture. Known as a sanctuary for street drifters from the late 80s through the early 2000s, this pass connects the cities of Izu and Ito. In Assetto Corsa, it is a flowing, high-speed masterpiece that trades the tight claustrophobia of many Japanese touges for wide lanes and rhythmic elevation changes, making it the ultimate playground for committed tandem runs.
Kameishi is a standout because of its unique road architecture—a rarity in the world of mountain passes that allows for aggressive, side-by-side action.
The Three-Lane Uphill: The defining feature of Kameishi is its unusual three-lane layout. This extra breathing room allows you to push the car harder, giving you the space to link long, sweeping transitions without immediate fear of the guardrails.
The Izu Skyline Ridge: As part of the 40km Izu Skyline, the road follows the mountain ridges of the Fuji-Hakone-Izu National Park. On a clear run, you’re treated to spectacular vistas of Sagami Bay and Mount Fuji, though the focus here is strictly on the next apex.
The Technical Interchanges: The track features technical sections near the Kameishi Pass Interchange (IC). These transition points require precise braking to settle the car before it plunges back into the fast, flowing sectors that define the climb.
Flowing Elevation Changes: The pass is a masterclass in vertical rhythm. The constant rise and fall of the terrain tests your suspension’s ability to maintain grip under compression, rewarding drivers who can use the car's weight to pivot through high-speed turns
Welcome to Ikawa Touge, a hidden relic of the Shizuoka mountains. Nestled near the Ikawa River and the scenic Ikawa Dam, this pass was once a buzzing sanctuary for the underground street drifting scene of the early 2000s. While the real-world road has since quieted down, it lives on in Assetto Corsa as a high-fidelity time capsule of Japanese car culture. It is a technical, low-speed gauntlet that rewards rhythm and precise car control over raw horsepower, framed by the lush, dense forests typical of the Shizuoka region.
The course is a tight, rhythmic flow of technical corners that follow the natural contours of the Ikawa valley, demanding constant focus through its narrow lanes.
The Ikawa Dam Paddock: The starting point near the engineering marvel of the Ikawa Dam. This wide area serves as the staging ground for drift sessions, offering a brief moment of open space before the road constricts into the mountain.
The Riverbank Sweepers: The initial section follows the path of the river, featuring medium-speed corners that allow you to find your car's balance. The proximity to the water and the vertical rock faces creates an echoing chamber for your engine note.
The Technical Forest Core: As you move deeper into the mountains, the canopy closes in. This is the heart of the touge, featuring a sequence of tight hairpins and off-camber transitions that were the primary playground for local drifters two decades ago.
The Discontinued Path (Haisen): The road frequently passes remnants of the region's industrial past, including old tunnels and abandoned rail lines from the Ikawa Line’s construction, adding a gritty, historic atmosphere to every run
Welcome to Gunsai, the "Cycle Sports Center" of Gunma Prefecture and the definitive home of the Hot Version Touge Showdown. Unlike the public mountain passes of the region, Gunsai is a closed-circuit bicycle track that has been repurposed as the ultimate playground for Japan’s top tuners. In Assetto Corsa, it is a high-speed, technical gauntlet where the road is narrow, the guardrails are non-existent, and the trees are hungry. This is where legends like the RE Amemiya RX-7 and the FEED FD3S fight for the title of "Touge Monster."
Gunsai is a 6-kilometre loop of high-intensity technicality. Because it was designed for bicycles, the road is incredibly narrow with zero runoff, demanding a "surgical strike" approach to every corner.
The Main Straight & Jump: The run kicks off with a high-speed blast past the staging area. The most iconic moment is the "jump" near the start—if your suspension isn't perfectly tuned, the car will settle poorly, throwing you off your line before the first turn.
The Technical Forest Sector: This is the heart of the "Touge Showdown." A relentless sequence of mid-to-high speed sweepers where the car is constantly under lateral load. The road is flanked by thick forest, creating a "green tunnel" that punishes the slightest miscalculation with a terminal collision.
The Uphill Hairpins: Toward the back of the circuit, the elevation kicks in. These tight corners test your car's mechanical grip and front-end bite. It’s the primary area for the "cat and mouse" battles to be won or lost, as the chasing car tries to stay glued to the leader’s bumper.
The Final Chicane: A high-stakes transition that leads back toward the main paddock. This section requires perfect weight transfer to navigate the quick left-right flick before the finish line.
Assetto Corsa. Unlike the focused, single-mountain runs of Gunma or Saitama, Project Touge is a massive, interconnected playground designed to capture the entire spirit of Japan’s mountain passes in one immersive map. Spanning an incredible 48 kilometres of winding roads, it is a technical marathon that blends steep elevation changes, sharp hairpins, and scenic vistas into the ultimate "freeroam" drifting experience.
Project Touge is built for flow and freedom, offering multiple layouts and technically demanding paths that range from dense forest tunnels to wide-open cliffside runs.
The 48km Network: This isn't just a point-to-point race; it is a giant network of roads where every intersection leads to a new challenge. It is perfect for long, sustained sessions where you can link drift transitions for miles without ever seeing the same corner twice.
The Hairpin Gauntlets: The map is famous for its "endless" series of technical hairpins. These sections demand precise throttle control and quick reflexes, challenging you to maintain proximity to the guardrails and dense trees as you navigate narrow paths.
Freeroam & Tandem Flow: Designed specifically for the drift community, the map features wide staging areas and "comfy" configurations that make it a favorite for online tandem trains. Whether you're leading a pack or chasing a door, the sheer variety of corners keeps the rhythm interesting.
Breathtaking Scenery: From the rugged cliffs to the dense, shaded forests, the track blends technical difficulty with a quintessential Japanese mountain aesthetic. It offers an authentic atmosphere for those seeking to replicate the excitement of real-world night runs.
