Mahoto Watanabe (ワタナベマホト, Watanabe Mahoto; born December 8, 1992) is a former Japanese YouTuber and rapper. He was part of the hip hop group Kaiware Hummer, releasing music under the stage name Bema. Watanabe first began posting videos on Nico Douga in 2007 and transitioned to YouTube in 2010, becoming one of the first YouTube personalities on YouTube Japan. He gained popularity with his radical video style, but he was also known for his caring personality for his junior YouTubers, who called him "Oyakata". He is famous for having trained up popular YouTubers such as Tokai On Air, Avntis, and Hekitora House. In January 2021, Watanabe allegedly solicited nude photos from an underage fan, which subsequently caused his agency Uuum to drop him as an act and YouTube to permanently ban his channel. In March 2021, he announced he was retiring from YouTube.
