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.
Yama, 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.
