RIZIN Super Atomweight Champion Seo Hee Ham has vacated her belt, per an announcement by the promotion on Friday.
The South Korean fighter captured the RIZIN belt on New Year’s Eve 2019, winning a split decision over former champion Ayaka Hamasaki at Saitama Super Arena in Saitama, Japan. The fight arguably crowned Ham as the pound-for-pound best atomweight in the world.
“I love you Japan,” said Ham via an Instagram story on Friday, captioning a photo of her championship win from 2019.
Ham, 33, is currently on a six-fight streak of wins since her return to atomweight in 2017.
Ham fought in the UFC from 2014 to 2016, although she had to move up to strawweight since the 105-pound division isn’t supported in the promotion. She attained one win and three losses before returning to the regional MMA scene.
Ham made her debut in Japanese promotion RIZIN in July of 2019, stopping Tomo Maesawa in the first round with knees to the head. She picked up a win in October over Miyuu Yamamoto before being given a title shot.
