Suikawari

Suikawari (西瓜割り^?, lit. Watermelon Splitting) is a traditional Japanese game that involves splitting a watermelon with a stick while blindfolded. Played in the summertime, suikawari is most often seen at beaches, but also occurs at festivals, picnics, and other summer events.

The rules are similar to piñata. A watermelon is laid out, sometimes on a tarp, and participants one by one attempt to smash it open. Each is blindfolded, spun around three times, and handed a wooden stick, or bokken, to strike with. The first to crack the watermelon open wins. Afterwards the chunks of watermelon produced are shared among participants
