Masahiro Yamamoto (山本真弘, Yamamoto Masahiro, born April 14, 1983) is a Japanese kickboxer who competes in the lightweight division. After beginning his career as a featherweight in 2002, Yamamoto became a mainstay in the All Japan Kickboxing Federation and first challenged for the AJKF Featherweight Championship in December 2004 when he fought to a draw with Genki Yamamoto. He then went on a hot streak in 2005, winning the IKUSA 2005 –60 kg Grand Prix in the process, and was given another chance at the AJKF Featherweight title in January 2006 when he beat Genki Yamamoto in a rematch to take the belt. The following years saw Yamamoto move up to lightweight and have more domestic success as he took the AJKF's Best of 60 kg Tournament 2007 and the Krush Lightweight Grand Prix 2009 before he emerged internationally with the It's Showtime promotion. He lost to Sergio Wielzen in his first attempt at the It's Showtime 61MAX Championship in December 2010 but came back to win the belt in July 2012 by defeating Javier Hernandez.
