Team Japan started as six-man team as team captain Nosawa from All Japan Pro Wrestling teamed with Osaka Pro Wrestling's Ebessan and Kamen competed in non-tournament exhibition match. They lost to Elix Skipper, Sonjay Dutt and Chris Sabin. For the World X-Cup event in May 2008, Nosawa dropped Ebessan and Kamen and replaced them with Mitsu Hirai Jr., Ryuji Hijikata and Taichi Ishikari, all of whom were like Nosawa from All Japan. Theyenjoyed some success in exhibitions and singles matches not related to the tournament itself, but failed to have any significant success in the actual tournament and were quickly eliminated, leaving Team Canada, Team Mexico, and Team USA for the finals which were held under Ultimate X rules.
After the X-Cup event, Nosawa teamed with fellow All Japan wrestler Kazushi Miyamoto for several months under the Team Japan name. They disappeared from TNA after Victory Road.
Team Japan returned to TNA for the World X-Cup Tournament 2006. On the March 11, 2006 episode of TNA iMPACT!, Mike Tenay said that Puma would be on Team Japan for the competition. Jushin Liger was shortly thereafter announced to be the captain of the team.
Rumored members of the team included Hiroshi Tanahashi, Black Tiger, and Tiger Mask. Oddly, the character of Black Tiger has always been that of a heel in Japan while Tiger Mask is the babyface. The characters are that of "twins" with Black Tiger being the "evil twin". They do not tag and this would have been considered an unusual decision for TNA to make. Fortunately, these were proven as nothing more than rumours, and none of the rumoured competitors were included on the team.
Team Japan made its return at Lockdown 2006, with members Hirooki Goto, Minoru Tanaka, and Black Tiger competing in an exhibition six man tag match against Team USA members Jay Lethal, Sonjay Dutt, and Alex Shelley. Team Japan pulled out the win in light of miscommunication on the part of Team USA.
Liger was supposed to be a part of the exhibition competitions at Lockdown, as he was slated to face off with Christopher Daniels. Due to travel conflicts, Liger was unable to make the pay per view, and TNA had to alter the card, declaring Daniels' opponent to be a mystery competitor. The competitor was later announced to be Senshi.
Liger did, however, compete in a second round match against Petey Williams from Team Canada. Liger pulled out the win after a double underhook faceplant after teammates Hiroko Goto and Black Tiger interfered in the match.
Team Japan was heavily favored to win the 2006 World X-Cup in light of TNA's talent-swap agreement with New Japan Pro Wrestling, but to the surprise of many, the team finished in last place. It is speculated that this may be due to a lack of participation from Team Captain, Jushin "Thunder" Liger who only made on-screen appearances in the tournament during Sacrifice. All four members of the 2006 Team Japan were also members of Liger's heel Control Terrorism Unit (C.T.U.) stable from NJPW.
