Despite its English-sounding name, Japan’s “Auto Race” is not car racing. It is a uniquely Japanese public motorcycle sport in which riders compete on minimalist machines built specifically for a paved, counterclockwise oval. The sound, staggered handicaps and extreme left-leaning posture make it unlike MotoGP, motocross or speedway.
A regulated local-government sport
Auto Race is conducted by local governments under the Small Motor Vehicle Racing Act and supervised by the Ministry of Economy, Trade and Industry. The JKA Foundation registers riders and racing machines and helps protect sporting integrity. Part of the proceeds supports local finance, mechanical industry, social welfare and other public programs.
Eight bikes, six laps and handicap racing
A standard field has eight riders. They race six laps on a 500-meter counterclockwise oval; because of the start position, the published standard race distance is 3,100 meters. Rider colors are fixed by number: 1 white, 2 black, 3 red, 4 blue, 5 yellow, 6 green, 7 orange and 8 pink.
In a handicap race, higher-rated riders start farther behind, creating a pursuit rather than one flat starting line. The trial-run time, handicap distance, recent results and dry or wet track condition all matter. Rain changes tire choice and riding style.
The machines have no brakes. This is not casual removal of a safety part: official explanations describe a purpose-built design intended to avoid sudden braking and rear-end impacts in close formation. Asymmetric handlebars, triangular-profile tires and minimal bodywork are optimized for repeated left turns.
Ticket types and buying with cash
Tickets are sold in ¥100 units. Choices include Win, Place, Exacta, Quinella, Trifecta, Trio and Wide. For a first attempt, Quinella—selecting the first two riders in either order—is easier to understand than an exact-order combination.
- Confirm the host track and race number.
- Check the trial run and handicap positions.
- Mark the ticket type, rider numbers and amount.
- Insert the card and cash into an official machine and check the paper ticket immediately.
A completed purchase cannot be cancelled. Online voting needs membership and compatible payment arrangements; an on-site official cash machine is often simpler for a short visit. A fixed ¥100–¥500 entertainment budget is enough to learn the process.

Frequently asked questions
Is this automobile racing?
No. Japanese Auto Race uses dedicated motorcycles. It is not a four-wheel car event.
Can I enter without betting?
Yes. General admission at Kawaguchi is free, so you can watch the trial runs, machines and handicap tactics purely as a sporting visit.
Do races run in the rain?
Wet-weather racing can take place with different tires, but severe weather or a safety decision can alter or cancel the program. Check the same-day notice.
