From September 8, 2024, J-PLACE Oi expanded its sales of Japan Racing Association betting tickets to all JRA races, according to the Japanese Wikipedia entry on Oi Racecourse1. The counter sits inside Oi Racecourse in Shinagawa ward, Tokyo, and sells JRA tickets on commission from the JRA1.
J-PLACE Oi opened in April 2013 inside the L-WING facility at the track, selling JRA betting tickets under commission from the Japan Racing Association1. Until the September 2024 change, that sales operation covered only part of the JRA program; the entry states the expansion to all races took effect from September 8, 20241. The source does not say how many races or meetings were covered before the change, or which JRA meetings were previously excluded.
Oi Racecourse is a local-government (chiho) racing venue, not a JRA track. It opened on May 2, 1950, is owned by Tokyo Keiba Co. and leased and operated by the Special Wards Racing Association, which races there under the name Tokyo City Keiba (TCK)1. It is one of the four tracks that make up the South Kanto public racing group, alongside Kawasaki, Urawa and Funabashi, and is the only one of the four with a right-handed course1. The venue has a stated capacity of 60,350 and a dirt track, with an inner course of 1,400m and an outer course of 1,600m1.
The track's own betting business has been changing. The source does not connect these changes to the J-PLACE expansion.

What it means for players
For anyone at Oi Racecourse on a race day, the J-PLACE counter now takes bets on the full JRA program rather than a limited set of races, so a single visit can cover both the local TCK card and JRA races run elsewhere in Japan1. That matters most for people who are already at the track for the local meeting and want JRA action without a separate trip to a JRA track or a WINS outlet.
The change does not alter what Oi itself races or how TCK bets work. Oi remains a local-government track operated by the Special Wards Racing Association under the Tokyo City Keiba name, and its own product is separate from the JRA races sold at the J-PLACE counter1. Nothing in the source indicates any change to who may bet, to identification requirements, or to the legal position of betting at the venue.
What happens next
No further steps tied to the J-PLACE expansion are given in the source.
