Ikuto Hidaka
Later in September, Sawa again made it to the semifinals of the Tenkaichi Jr. tournament, before losing to tag team partner Ikuto Hidaka. In the 2010 Furinkazan, Sawa opted to team with DDT Pro-Wrestling and Pancrase representative Hikaru Sato instead of Hidaka. However, with a record of one win and three losses, the team finished nowhere near a place in the finals. Despite their unimpressive tournament, Sawa and Sato received a shot at the NWA International Lightweight Tag Team Championship on January 1, 2011, but were unable to dethrone Kaijin Habu Otoko and Takuya Sugawara. On March 6 at Zero1's tenth anniversary event, Sawa attempted to win his first singles title in the promotion, but was defeated by Craig Classic in his match for the NWA World Junior Heavyweight Championship. On March 27, Sawa reunited with Ikuto Hidaka for a rematch for the NWA International Lightweight Tag Team Championship, but the two were again defeated by Otoko and Sugawara. On June 14, Sawa took part in Dick Togo's Zero1 retirement match, where he, Fujita "Jr." Hayato and Masato Tanaka were defeated by Togo, Funaki and Ikuto Hidaka. On September 14, Sawa entered the 2011 Tenkaichi Jr. tournament with a win over Takuya Sugawara. After defeating Susumu Yokosuka in the semifinals, Sawa defeated Fujita "Jr." Hayato on September 17 to win the tournament. As a result, Sawa received another shot at the NWA World Junior Heavyweight Championship, however, this time Zero1's version of the title, on October 2, but was again defeated by Craig Classic. On November 6, the day after the folding of Battlarts, Sawa wrestled his retirement match as Lingerie Mutoh, losing to World Wonder Ring Stardom representative Yoshiko. Three days later, Sawa was defeated by longtime tag team partner Ikuto Hidaka in his professional wrestling retirement match. At the end of the year, Zero1 fans voted Sawa the 2011 MVP.
