Toshihiro Adachi is a Japanese poker player and a regular competitor on the Asian poker circuit. He is best known for his consistency in South Korean events and his breakout victory at the AJPC Samurai Circuit in Incheon in late 2025.

Career Earnings & Biggest Results

Toshihiro Adachi ranks approximately 376th on the Japan All Time Money List (according to The Hendon Mob). His career is defined by frequent deep runs in tournaments held at Paradise City Incheon, a popular destination for Japanese players.

His Best Live Cash came in December 2025 at the All Japan Poker Championship (AJPC) Samurai Circuit in Incheon, South Korea. Adachi topped the field in the ₩1,650,000 Main Event, officially finishing 1st to claim the title and a payout of ₩20,811,000 (~$14,113) following a heads-up battle with fellow Japanese player Shin Watanabe. This victory marked his first major circuit title.

Adachi has demonstrated remarkable consistency at the AJPC Samurai Circuit over the years:

4th Place in the “The Closer” event (September 2024) for ₩3,169,000.
6th Place in the AJPC Championship (August 2023) for ₩4,074,000.
6th Place in the Samurai Event (December 2024).

Biography & Poker Background

Based in Japan, Toshihiro Adachi focuses primarily on the Japan Open Poker Tour (JOPT) and international stops in South Korea. He has established himself as a “Incheon Specialist,” regularly caching in events hosted at the Paradise City Casino.

While he spent years grinding smaller side events and navigating mid-sized fields, his 2025 Main Event win elevated his status. Overcoming a field of 85 entries in the AJPC Main Event proved his ability to close out tournaments against tough regional competition.

Play Style & Strategy

Adachi’s results point to a resilient and consistent style. His multiple final table appearances in “Closer” and “Championship” events suggest he excels in the late stages of tournaments, often navigating the ICM (Independent Chip Model) pressure well. His ability to secure a title against Shin Watanabe – who technically took home a slightly larger cash prize in 2nd place, likely due to a deal – shows Adachi’s focus on securing the trophy and the win.
