Four Bouts Official for Rizin 52 on March 7

Rizin Fighting Federation has confirmed four bouts, including a
super atomweight showdown between Saori
Oshima and Keito
Oyama, for its first event of 2026.

Rizin
52 on March 7 will also include the following three contests:
Luiz
Gustavo vs. Taisei
Sakuraba at lightweight; Takaki Soya
vs. Tony
Laramie at flyweight and Viktor
Kolesnik vs. Kazuki
Aimoto at featherweight.

Rizin 52 takes place at Ariake Arena in Tokyo and is availabile on
pay-per-view via Rizin.TV.

The promotion also announced that Rizin Landmark Vol. 13 will take
place on April 12 at Marine Messe Fukuoka in Fukuoka Japan. No
fights were confirmed for that event.

Oshima won her first four Rizin appearances to eventually earn a
super atomweight title shot. “Little Giant” came up short in that
opportunity, falling to women’s pound-for-pound stalwart Seika Izawa
via unanimous decision at Rizin Landmark Vol. 12 this past
November.

Oyama, who is more commonly known as “Kate Lotus,” will take a
four-bout winning streak into her matchup with Oshima. Two of those
victories — decision wins over Bo Mi Lee and
Yu Ri
Shim — occurred under the Rizin banner.
