Kohei Sato
In 2017, Sakuragi switched AJPW by Pro Wrestling Zero1 as his main field. He participated in that year's Fire Festival, gaining high victories over Shogun Okamoto and Kohei Sato, but ultimately came short. He bounced back by winning the previously vacated Zero1 United National Heavyweight Championship against Hartley Jackson, which he retained until losing it in 2018 to Chris Vice. Super Tiger then repeated participation in the 2018 Fire Festival, achieving again important wins over names like Shinjiro Otani, Sugi and Hiroshi Yamato, and returned again after a hiatus at the 2019 edition, adding another win over Masato Tanaka.
