By Kelli Luu | 30 Jun, 2026

After winning back-to-back titles in the World Series of Poker Ladies Championships in 2024 and 2025, Shiina Okamoto is successfully cementing her name as one of the best at the poker table.

Shiina Okamoto is representing Japan on an international level becoming one of the most recognizable names in professional poker. 

She was born in Tokyo, Japan and first emerged onto the poker scene in 2023 during the WSOP $1,000 Ladies Championship. Okamoto competed amongst 1,295 entrants and made her way to the final table before finishing as runner up, taking home over $118,000. While some players would have felt satisfaction taking home the second place win, Okamoto used it as motivation for the year after. 

In 2024, Okamoto returned to Las Vegas and once again made it to the final table of the Ladies Championship except this time, she defeated 1,245 players to take home her first WSOP gold bracelet and the first place prize of $171,732. This win put a huge spotlight on her status in the poker world and cemented Okamoto as one of Japan’s most elite players. 

To continue her legacy, Okamoto returned to the Ladies Championship again in 2025 where she defeated a record-breaking 1,368 contestants. Okamoto’s second consecutive WSOP win made her the first player ever to win the tournament in back-to-back years after finishing as runner-up the year before. Her impressive three-year run is considered one of the greatest in the tournament’s history. 

Beyond the Ladies Championship, Okamoto has had major success in other poker circuits, recording cash finishes at the European Poker Tour, WSOP Europe, and other tournaments throughout Asia. As of 2026, Shiina Okamoto’s calm demeanor and strategic decision-making  has earned herself over $1 million in live tournament winnings. 

Traditionally, poker has always been dominated by men, but Shiina Okamoto has risen as one of the modern faces of the game and is inspiring women in Japan and across Asia to pursue competitive poker.
