Masanobu Fuchi
On August 28, 2004, Raijin debuted for All Japan Pro Wrestling losing to Ryuji Hijikata. His early years with All Japan would be mostly uneventful which is normal for a new wrestler in a Japanese promotion. On June 17, 2005, Raijin teamed with Nobukazu Hirai in a tournament to determine the number one conders for the All Asia Tag Team Championship but lost to Katsuhiko Nakajima and Tomoaki Honma. In November, Raijin and Kohei Suwama participated in the 2005 Real World Tag League but would not pass the round robin stage. On January 4, 2007, Raijin along with Kikutaro and Nobutaka Araya took on, and lost to, El Samurai, Masanobu Fuchi and Ryusuke Taguchi at New Japan Pro-Wrestling's Wrestle Kingdom in Tokyo Dome. On May 13, All Japan said farewell to Raijin along with Brute Issei, who both went on overseas training excursions.
