With the heat continuing to rise and the humidity like a sticky, unwanted blanket upon us, there’s only one thing to do: escape. Away from the blistering concrete of the city, the rivers and gorges near Tokyo offer a brief respite. The temperature of the water heats up in the summer months, making it perfect for a paddle or swim.
Add these refreshing rivers and secluded splashing spots to your visit wish list. Many of the places are covered with trees in the summer, so they offer ample shade, meaning you don’t need to worry too much about sunburn.
These spots are all within three hours of Tokyo by public transport, so you can get out early and return late for a full day’s worth of frolicking. We also recommend staying overnight if you can.
