Experience a unique blend of entertainment, gastronomy, and thrilling horse racing at the Oi Racecourse (大井競馬場) in Tokyo. In this video, YouTuber 高尾てんぐ。Takao Tengu takes us on a lively vlog visit to the racecourse's restaurant, Diamond Turn (ダイアモンドターン), on March 25. This buffet-style, all-you-can-eat and all-you-can-drink establishment is tailor-made for race enthusiasts who enjoy good food and drinking while watching the action unfold on the track.

Located inside Tokyo City Keiba (TCK), Diamond Turn offers a premium racetrack dining experience. Seating is arranged to face the racecourse, giving customers prime views of the high-energy races while indulging in an extensive buffet and free-flowing drinks. The video showcases not only the broad variety of gourmet dishes on offer—from grilled meats to fresh seafood and traditional Japanese fare—but also the friendly, lively atmosphere of the venue.

Tengu participates in the betting as well, with a focus on the trio-style bets known in Japan as “sanrenpuku” (三連複), where bettors pick three horses that will finish in the top three in any order. Between thrilling races and plate refills, he shares insights on betting strategies and reactions to the wins and near-misses. Despite a few minor issues in video clarity due to technical problems, viewers are still able to clearly feel the excitement and dynamic vibe of racetrack culture.

The Oi Racecourse is located in Shinagawa Ward and is particularly known for its night races and involvement in the regional Nankan Keiba (南関競馬) circuit. TCK and Diamond Turn provide a truly local way to spend an evening in Tokyo—great for both tourists and locals looking to enjoy Japanese-style gambling culture accompanied by food and drink indulgence.

If you’re planning a visit to Tokyo and are open to alternatives to typical sightseeing, a night at Oi Racecourse might be just the kind of off-the-beaten-path experience you’re looking for.
