A few preliminary-card fighters are listed in Japanese because DEEP has not published a standard romanisation for their ring names. We would rather print the name as announced than guess at a reading.
What to watch
A belt is on the line at Megaton. Megaton is DEEP's open-weight class, and Shoma Sivisai is the named challenger to champion Taisei. The bout is scheduled for three five-minute rounds rather than the shorter format, so both the single-shot finish that heavyweight bouts invite and the conditioning gap that opens up late are live questions.
Satoru Kitaoka is still walking into Korakuen Hall. Kitaoka, a fixture of Japanese MMA since its earliest professional era, meets Yajuro Yamazaki at lightweight. Fellow veteran Daisuke Nakamura is also on the card against Asuka Tsubaki — a good illustration of what this promotion is: a domestic circuit where careers are long and the room knows every name.
The lower weights are reshuffling. Daichi Kitakata vs Jo Arai at strawweight and Rikuto Shirakawa vs Kenta Takizawa at bantamweight both involve fighters in the divisional mix. DEEP is deep at the lighter weights, so results here tend to move the title picture directly.
