Goldfish scooping (金魚すくい) during the summer festivals!

Kingyo sukui (金魚すくい) is a traditional Japanese game in which participants use paper scoopers to scoop goldfish in Japanese summer festivals. Snatching goldfish, dipping for goldfish, and other similar terms are also used to describe it. The terms "kingyo" and "sukui" both refer to goldfish. Goldfish can occasionally be substituted with bouncy balls. There will almost always be at least one stall where you may attempt scooping goldfish with a tiny paper net called a poi among the food and souvenir stalls. Since the Edo Period, summer festivals have continued to feature the custom.
