2026 Kasen Kankyo Rakuen Oasis Park Water Play Plaza Full-Day Course

This is a local outing course for a full day of play, built around the Kasen Kankyo Rakuen Oasis Park Water Play Plaza (Rainbow Fountain, Mist Play Area and Wanpaku Field) in Kasen Kankyo Rakuen (河川環境楽園) in Kakamigahara City (各務原市). The Rainbow Fountain runs from Saturday, April 25 to Wednesday, September 30, 2026, from 9:30 to 22:00, and is lit up from 18:00. The Mist Play Area runs from 9:30 to 21:00 between Saturday, July 18 and Monday, August 31, and from 9:30 to 17:00 at other times. Wanpaku Field, aimed at children aged 3 to 6, runs from 9:30 to 17:00 between Saturday, April 25 and Wednesday, September 30, and all of them are cancelled in rain. Admission and parking are both free, and it is great that you can match the play to each age, with the gently pressured Rainbow Fountain and a Mist Play Area that even children aged 3 and under can enjoy safely. In the morning, see the creatures of the Kiso River (木曽川) at Aqua Toto Gifu, the world freshwater fish aquarium (世界淡水魚園水族館) on the same grounds, and take your time in the cool galleries. Have lunch inside Oasis Park, enjoy the view over the Nobi Plain (濃尾平野) from the Ferris wheel, and then head for the water. With shops and restaurants all in one place, it is a reassuring spot for families who need to pick up clothes or drinks. After splashing around until evening, pack up and head home before it gets dark.
