On July 14, 2008, Gentaro made his debut for women's wrestling promotion Ice Ribbon, teaming with Riho to defeat Emi Sakura and Ribbon Takanashi in a tag team match. Gentaro returned to Ice Ribbon seventeen months later on December 20, 2009, when he began working regularly for the promotion, becoming only the second male wrestler to have a regular spot on the roster (the first being Ribbon Takanashi). In March 2010, Gentaro got involved in a storyline with Miyako Matsumoto, starting on March 31, when he successfully defended the DDT Extreme Championship against her. Following the match, Gentaro and Matsumoto formed a tag team, wrestling Keita Yano and Munenori Sawa to a fifteen-minute time limit draw on April 7. However, problems quickly arose between the two, when Matsumoto revealed that Gentaro's fellow Freedoms worker Jun Kasai was her favorite wrestler. On April 17, when Matsumoto and Kasai were named the number one contenders to the International Ribbon Tag Team Championship, held by Kazumi Shimouna and Nanae Takahashi of Passion Red, Gentaro interrupted the announcement and demanded to be included in the match. When Emi Sakura agreed to change the match, Keita Yano entered the ring and attacked Matsumoto, revealing himself as Gentaro's partner. The three-way match, contested under hardcore rules, took place on May 3, and saw Matsumoto and Kasai become the new champions. On August 11, Gentaro formed a new tag team with Mai Ichii, with the two defeating the reigning International Ribbon Tag Team Champions, Chii Tomiya and Isami Kodaka, in a non-title match in their first match together. As a result, Gentaro and Ichii were granted a shot at the title on September 23, where they defeated Tomiya and Kodaka to become the new International Ribbon Tag Team Champions. However, Gentaro's and Ichii's reign ended just two days later, when they were defeated by Emi Sakura and Nanae Takahashi. Since losing the International Ribbon Tag Team Championship, Gentaro has mainly remained outside of storylines, wrestling only sporadically, and instead began working as the lead play-by-play announcer on Ice Ribbon's broadcasts on Ustream and Samurai TV.
