Sword attacks in Japan

Tsujigiri ( or , literally "crossroads killing") is a Japanese term for a practice when a samurai, after receiving a new katana or developing a new fighting style or weapon, tests its effectiveness by attacking a human opponent, usually a random defenseless passer-by, in many cases during night time. The practitioners themselves are also referred to as tsujigiri.
