Japanese drift glossary: 60 terms explained in one sentence

Updated 29 October 2026 · 60 terms · one sentence each, 30 words or fewer

TSUISO’s glossary defines 60 terms used at Japanese drift events and circuits, in one sentence each; updated 29 October 2026.

Every definition below stands on its own, so it can be quoted as written. Where a definition carries a yen figure, the date in brackets is when that figure was last read on the venue’s or operator’s own page. For the longer explanations, the paddock chatter and the full A to Z of 104 listing and parts words, read the long-form guide to Japanese drift slang; the definitions here agree with it.

Events and days

The words on a Japanese circuit calendar or entry page that decide what you can actually do on the day.

# Sōkōkai 走行会: A privately organised track day: a shop or crew rents the circuit and sells entries, which is how most drifting in Japan happens.
# Organiser day: A sōkōkai in English: a day run by an outside shop or team rather than the circuit, with its own entry form, fee and rules.
# Drift day ドリフトデー: A day on which the circuit itself sells drift running at its own published fee, booked with the circuit rather than through an organiser.
# Track day: Any organised circuit day for road or race cars; in Japan it is usually a sōkōkai, and drifting is allowed only when the listing says so.
# Free-run / free running フリー走行: Open track time the circuit sells by the slot, hour or day with no organiser session structure; some venues require their own licence for it.
# Grip day グリップ: A circuit day for conventional lap driving on which drifting is not allowed; many Japanese circuit calendars alternate grip days and drift days.
# Matsuri 祭り: Festival; a drift matsuri opens several courses at once and runs day into night with no judging, and Ebisu Circuit holds three a year.
# Renshūkai 練習会: A practice-focused day, usually the most beginner-friendly listing on a circuit calendar.
# Kashikiri 貸切: Private hire of the whole course; on a schedule it means the track is booked and you cannot turn up expecting to run.
# Tansō 単走: A solo run judged on its own, the first stage of every drift competition before the tsuiso bracket.
# Tsuiso 追走: The chase run: two cars on track together, judged as lead and chase in competition and simply run together, unjudged, at grassroots level.
# Taiken sōkō 体験走行: An experience or taster drive, often in the venue’s own car with an instructor beside you.
# Entry sheet エントリーシート: The organiser’s entry form, almost always in Japanese, returned by web form, email or fax and confirmed with a bank transfer.
# Uketsuke 受付: Reception, where you sign in on the day; the same word means the entry period for an event.
# Waku 枠: A time slot on the day’s running schedule; a sōkō-ken (走行券) is the run ticket for it.
# Kusa-dori 草ドリ: Grassroots drifting: the amateur end of the scene and most of its events.
# D1GP (D1 Grand Prix) D1グランプリ: Japan’s top professional drift series: a solo tansō stage, then a 16-car tsuiso bracket, with licensed drivers only and no open entry.
# D1 Lights D1ライツ: The second tier of the D1 ladder, between D1 Grand Prix above it and the regional D1 NEXT series below.
# D1 NEXT D1ネクスト: The open-entry regional tier of the D1 ladder, run as six regional series in 2026 and the level where most overseas entrants start.
# FDJ (Formula Drift Japan) フォーミュラドリフトジャパン: The Japanese arm of Formula Drift: FDJ is the professional tier, FDJ2 the second tier and FDJ3 the entry tier.
# G1GP: “Gaijin No.1 Grand Prix”: a drift competition open only to overseas drivers, run at Ebisu Circuit on the Friday before each Drift Matsuri.

Driving and judging

What you hear in the paddock and from the judges’ box.

# Furidashi 振り出し: Initiation: the moment the car is thrown into the drift, and the first thing the judges scrutinise.
# Furikaeshi 振り返し: The transition: snapping the car from one direction of drift to the other between linked corners.
# Manji マンジ: Side-to-side weaving drift along a straight, named for its zig-zag shape; show, not speed.
# Clipping point クリップ: A marked inner point the judges want the front of the car to attack; an outer zone (ゾーン) is where they want the rear.
# Tandem: The English word for tsuiso: two cars drifting together, the lead car setting the line and the chase car following as close as it can.
# Lead / chase 先行／後追い: The two roles in a tsuiso battle, senkō (lead) and atooi (chase); a battle is two runs with the roles swapped.
# Kakudo 角度: Drift angle; kirekaku (切れ角) is steering lock, the angle the front wheels can turn.
# Hakuryoku 迫力: Impact or presence: a judging word for speed, angle and commitment seen together.
# Kansei drift 慣性ドリフト: Inertia or feint drift, started with weight transfer rather than the handbrake.
# Clutch kick クラッチ蹴り: Snapping the clutch to break rear traction and start or extend a drift; kurattchi keri in Japanese.
# Saido サイド: The handbrake, from “side brake”; a yuatsu saido (油圧サイド) is a hydraulic handbrake.
# One more time ワンモアタイム: A tsuiso battle re-run, ordered when the judges cannot separate the two cars.
# Shinsa 審査: Judging; the shinsa-in (審査員) are the judges and the shinsa-ku (審査区間) is the judged section of the course.
# Zenkai 全開: Full throttle, flat out: a corner or run driven with no lift; the word also turns up in organiser names such as ZENKAI DRIVING.

Cars and parts

The car itself, and the words in a Japanese parts or car listing.

# Dorisha ドリ車: Drift car, from dori (drift) and sha (car); a state of preparation rather than a model: knuckles, diff, hydraulic handbrake, cage.
# Missile car: English drift slang for a cheap, battered practice car that is driven hard with little concern for its bodywork.
# Kei 軽: Japan’s smallest road-car class, with engines capped at 660 cc; Motorland Kijo sells its drift hour in a kei car.
# Hachiroku ハチロク: The AE86 Corolla Levin and Sprinter Trueno, from the digits 8 and 6; no operator in Japan rents one to drive.
# S-chassis Sシャシ: The Nissan Silvia and 180SX family, S13 to S15; with the Toyota JZX saloons, the cars drift rental operators in Japan actually offer.
# JZX (JZX90 / JZX100): Toyota’s Chaser, Mark II and Cresta saloons by chassis code, the big-sedan alternative to the S-chassis in Japanese drifting.
# Nakkuru ナックル: The steering knuckle; a modified knuckle adds steering angle.
# Shakōchō 車高調: Coilovers, from “height-adjustable suspension”.
# Defu デフ: The differential; a mechanical limited-slip (機械式LSD) is what drifters fit, and 2-way is the drift preference.
# Rental drift car レンタルドリ車: A prepared car an operator supplies for a session or a day; published day rates run from ¥48,000 plus entry to ¥420,000 all-in (28 September 2026).

Paperwork and money

Licences, forms, insurance and the fees that sit around the running fee.

# Licence (circuit vs driving) ライセンス／免許: A circuit licence (ライセンス) is a venue’s own membership, needed for free running at some circuits; a driving licence (免許, menkyo) is the road one.
# IDP (International Driving Permit) 国際免許: Japan accepts it on public roads only under the 1949 Geneva Convention; on a closed circuit each venue sets its own licence rule.
# Shaken 車検: The roadworthiness inspection; a car with none cannot be driven on public roads, which is why track-only drift cars travel by transporter.
# Seiyakusho 誓約書: The pledge or waiver form signed before running.
# Dōjō hoken 同乗保険: Compulsory passenger insurance for riding along, ¥500 per person at Ebisu Circuit (29 September 2026).
# Hanko ハンコ／印鑑: A personal seal used instead of a signature on some Japanese forms, including some circuit licence applications.
# Gate fee 入場料: Per-person admission to the circuit site, typically ¥500 to ¥1,700, often charged to everyone on site including passengers (circuit pages, August to September 2026).
# Masshō 抹消: Deregistration; yushutsu masshō (輸出抹消) is the export deregistration that starts a car’s journey abroad.
# Shiharai sōgaku 支払総額: The on-the-road total a Japanese buyer pays, as opposed to hontai kakaku (本体価格), the body price before fees.

Places

Where it happens, and where it does not.

# Touge 峠: Mountain pass, where the sport was born; the word survives on purpose-built courses such as Ebisu Circuit’s Touge course.
# Daikoku PA 大黒PA: A Yokohama expressway parking area famous for car meets; it has no pedestrian access, closes at weekends from about 20:30, and is not a drift venue.
# Pit ピット: A pit garage, often sold separately at a matsuri; at Ebisu’s Drift Matsuri a pit adds ¥2,000 to ¥10,000 to the entry (6 October 2026).
# Paddock パドック: The open area where entrants park and set up for the day; Mobara Twin Circuit charges ¥1,000 a paddock space.
# Kuru Kuru くるくる: “Round and round”: Ebisu Circuit’s skid pads are named Kuru Kuru Land, where most people’s first donuts happen.
# Drift taxi / ride-along 同乗走行: Riding as a passenger with an experienced driver; published prices run from ¥500 a ride to ¥50,000 per car for Ebisu’s 45-minute Drift Taxi (29 September 2026).

Where these words turn up

Sōkōkai, kashikiri, free-run and drift day are the words that decide which dates on the event calendar a visitor can actually join.
Licence, gate fee and free-run are the fee lines on every venue page in the track directory.
Rental drift car, drift taxi and taiken sōkō are priced operator by operator in the drift car rental directory.
What each of those costs in yen, with the date it was checked, is on the cost fact sheet.
D1GP, D1 Lights, D1 NEXT and FDJ results for overseas drivers are tracked on the overseas drivers page.

Romanisation uses macrons where the Japanese has a long vowel (sō, not so); the long-form article uses the plain spelling. Kanji and katakana are given so you can match the word on a Japanese entry form or calendar.
