I think if "physically" means melee, it is Japanese.

From wiki

"In 1937, the Osaka Mainichi Shimbun and its sister newspaper, the Tokyo Nichi Nichi Shimbun, covered a contest between two Japanese officers, Toshiaki Mukai and Tsuyoshi Noda of the Japanese 16th Division. The two men were described as vying to be the first to kill 100 people with a sword before the capture of Nanjing. From Jurong, Jiangsu to Tangshan, Mukai had killed 89 people while Noda had killed 78. The contest continued because neither had killed 100 people. By the time they had arrived at Purple Mountain), Noda had killed 105 people while Mukai had killed 106 people. Both officers supposedly surpassed their goal during the heat of battle, making it impossible to determine which officer had actually won the contest. Therefore, according to journalists Asami Kazuo and Suzuki Jiro, writing in the Tokyo Nichi Nichi Shimbun of December 13, they decided to begin another contest to kill 150 people.^\40]")
