Battling it out in such events as Walking on Water, Moat Wall Climbing, Moat Wall Diving, Water Spider River Crossings and Star Throwing, combatants took part in the All Japan Ninja Championships.
The Ninja Games took place in Koga, a sleepy backwater in Shiga Prefecture that lays claim to being one of the homes of ninjutsu, or "stealth arts," a martial arts technique that has made Japan famous across the globe.
Koga, which sells itself as a tourist destination through its centuries old connection to Koga-style ninja, this year welcomed 84 contestants for its 20th annual ninja contest, Shukan Shincho notes.
