Munenori Sawa (born April 20, 1979) is a Japanese professional wrestler. He was trained by and spent his entire career in the BattlARTS promotion, adopting the promotion's "Bati Bati" wrestling style, known for its stiff strikes and submission-based shoot wrestling, but would often also incorporate comedy into his matches, especially when performing as Lingerie Mutoh, his comedic take on Keiji Mutoh. Besides Battlarts, Sawa also worked for various other promotions in Japan, Germany and the United States, most notably Pro Wrestling ZERO1, where he became an NWA Intercontinental Tag Team and NWA International Lightweight Tag Team Champion and won the 2011 Tenkaichi Jr. tournament, and where he wrestled his initial retirement match on November 9, 2011, four days after the folding of BattlARTS. Since his initial retirement from professional wrestling, Sawa has wrestled grappling matches for ZST and has wrestled as Ippanjin Munenori Sawa (lit. "Ordinary Person Munenori Sawa"). He has wrestled more since 2024, mainly under his Ippanjin persona, which parodies mainstream Japanese politics.
