Sumire Uenomachi

Sumire Uenomachi is a Japanese professional poker player who has been active in the Asian poker scene, particularly in events hosted by the Asian Poker Tour (APT). She is often described as a 'poker OL' (office lady) in Japanese media, balancing her poker career with a day job. Uenomachi has become a notable figure in promoting poker among women in Japan, where the poker community is still growing.

World Series of Poker

Uenomachi's most notable achievement came at the 2025 World Series of Poker (WSOP) in Event #70: $1,000 Ladies Championship. She navigated a field of 1,368 entries to reach the final table, ultimately finishing in 7th place for a cash prize of $26,131. At the final table, she started as the short stack and was eliminated by eventual champion Shiina Okamoto, who held A♣Q♣ against Uenomachi's A♥10♦.

Asian Poker Tour

Uenomachi has recorded consistent cashes in APT events, particularly in the Women's Event. At APT Taipei 2026, she finished 3rd out of 59 entries in a Women's Event with a buy-in of 8,000 TWD, earning $2,800 (approximately 82,000 TWD). The previous year, at APT Taipei 2025, she placed 4th out of 94 entries in the Women's Event (buy-in 12,000 TWD), taking home $2,700 (approximately 79,000 TWD). According to Somuchpoker, her total live earnings are estimated at $11,670, with a biggest win of $2,825, though these figures may not include her WSOP cash.

Based on her WSOP elimination hand, Uenomachi is not afraid to take aggressive action when short-stacked, shoving under the gun with A♥10♦ for 11 big blinds. This suggests a willingness to risk her tournament life with a strong but not premium hand. In broader terms, she is described as having a tight-aggressive style, patient in waiting for opportunities, and skilled at using position to apply pressure.

Uenomachi has been part of a wave of Japanese players making their mark on the international poker scene. She has participated in ABEMA's Queen of Poker tournament, further raising her profile in Japan. She has spoken about the challenges faced by women in poker, noting that Japanese women are often undervalued, and she aims to inspire more women to take up the game. Her consistent cashes in APT events and her deep WSOP run have cemented her reputation as a rising star in Asian poker.
