Emi Sakura
On October 15, 2006, Takanashi, working under the ring name Ribbon Takanashi, made his debut for the newly founded women's professional wrestling promotion, Ice Ribbon, teaming with Makoto in a losing effort against the team of Choun Shiryu and Riho. Takanashi has wrestled for the promotion regularly ever since, becoming the only male wrestler to hold a regular spot in its roster, while also helping Emi Sakura in training wrestlers for the promotion. On July 29, 2008, Takanashi won his first title in Ice Ribbon, when he, working under his transvestite character Masako Takanashi, teamed with Chounko to defeat Etsuko Mita and Makoto for the International Ribbon Tag Team Championship, with the two becoming the first male wrestlers to have held the title. On October 24, they lost the title to Riho and Yuki Sato in their first defense. Returning to the Ribbon Takanashi ring name, Takanashi, teaming with Emi Sakura, attempted to regain the title from Riho and Sato on November 15, but the two were unsuccessful in their challenge.
