Japan Pro Wrestling had a working agreement with All Japan Pro Wrestling. While there, Kobayashi feuded with Tiger Mask II, and he held the NWA International Junior Heavyweight Championship by defeating Dynamite Kid on June 13, 1985 and the World Junior Heavyweight Championship after defeating Hiro Saito on November 23, 1986, and also feuded with All Japan's loyalists, such as Norio Honaga, Jumbo Tsuruta, Takashi Ishikawa and Mighty Inoue.
