Enjoy river play in the clear flow of the Arakawa until evening
About this spot
Kawasemi Riverside (かわせみ河原) is a river play spot on the Arakawa River flowing through Yorii Town, Osato District. Hours are 9:00 to 17:00, and from spring through autumn it bustles with people canoeing and drive-in camping, along with families enjoying barbecues. The riverbank is spacious, and everyone can enjoy it at their own pace, from small children paddling calmly in the shallows to older children playing in the slightly deeper flow. Lush green mountains surround the area, so you can pass unhurried hours to the murmur of the river.

Tips
The water can feel cold when the sun is weak, so entering during the warmer hours is recommended. The riverbank has many stones and can be slippery, so amphibious shoes are reassuring. There is often no shop nearby, so prepare drinks and snacks in advance.
