Nagashi Soumen 流し素麺 is a Japanese Summer tradition which consists on putting noodles (Soumen, 素麺) on a bamboo cane and leaving them fall along together with water. If you participate you will have to catch the noodles with your chopsticks as they pass in front of you. The more you catch the more you eat!
Last week in Osaka a 30 meters Nagashi Soumen was organized.
