Japan's telephone and internet betting system for public racing, known as denwa tohyo, now operates through two methods only. As of 1 July 2024, the available routes are ARS, an audio response system using a push-button telephone, and I-PAT, the internet-based system1. The older CRT method, in which an operator took the bet over the phone, has been abolished and replaced by ARS1.
The system has a long history in central racing (JRA), where it was first introduced in 19911. The PAT method, which used dedicated terminals and software, ended its service at the end of July 20151. I-PAT began in 2002 and has since become the main route, allowing betting from a computer, smartphone or tablet1. Under the current rules, bets are placed in units of 100 yen for all bet types, and the cut-off is two minutes before the race for ARS and JRA Direct, and one minute before for I-PAT and PAT1. JRA Direct requires a minimum purchase of 1,000 yen in 100 yen units1.
Two linked services remain in place. JRA Direct is supported by ten credit card companies1. Membership carries no joining fee or annual fee, and anyone aged 20 or over who is not barred under the relevant laws may take part1.
The service covers all races held nationwide in central racing, regional racing, keirin, boat racing and auto racing1. Bets can be placed from 7am on the day of the race for afternoon races, or from 7am the previous day for morning races, up to two minutes before the scheduled start1. Frame quinella (wakuren) and WIN5 are not sold through this route1. The maximum number of runners JRA can handle is 241.
What it means for players
For anyone betting on Japanese racing from inside the country, the practical effect is that the phone-based route now means ARS or I-PAT, and the older operator-assisted CRT calls are gone1. Soku PAT remains the fast route for people who already hold an account at one of the nine partner banks, while JRA Direct runs through ten credit card companies1. Joining is free, but the account arrangements differ by provider, and some banks do not handle evening or night race meetings, so the racing body or the bank's own notices are the place to check1. Bets are in 100 yen units, with JRA Direct requiring at least 1,000 yen1. Frame quinella and WIN5 cannot be bought this way1.
