Yuki Sato (佐藤悠己, Satō Yūki) (born November 25, 1985)[3] is a Japanese
professional wrestler currently signed to
Pro Wrestling Noah, where he performs under the ring name Amakusa (stylized in all caps). He previously wrestled in Noah as Haoh (覇王, Haō), in
Kaientai Dojo under his real name, and in
Michinoku Pro Wrestling as Kenbai (剣舞, Kenbai).
In December 2019 he moved to
Pro Wrestling Noah as Haoh, and began teaming regularly with the former
Hi69, who took the name Nioh. In January 2022, however, after being unable to win the
GHC Junior Heavyweight Tag Team Championship despite several shots, Haoh turned on Nioh, and on April 29 Haoh defeated Nioh in a "loser must change his name" match. On June 23, however, Haoh lost a "loser leaves town" match to
Tadasuke, with which he took time off in order to return on an independent card in
Tlalpan,
Mexico, repackaged as Amakusa, a gimmick he kept upon returning to Japan and NOAH on November 11. On December 12, Amakusa defeated
Dante Leon to win the
GHC Junior Heavyweight Championship for the first time, and on March 9, 2023, he successfully defended the title against his former partner Hi69.
