Various natural locations across Japan are being promoted as cooling spots to provide relief from summer heat waves.

In Okayama Prefecture, Shinjo Village features the ‘Male Falls’ and ‘Female Falls,’ alongside spring water at Yadoro that residents claim can replace an air-conditioner because “even in summer it feels cold.” Additionally, the Manki Cave in Niimi City offers a year-round temperature of approximately 15 °C.

Other highlighted sites include Ayugaeri Falls in Mitoyo, known for its blue basin and forest bathing opportunities, and Sengen Valley in Kagamino, where visitors can experience Karane Falls and participate in catching and grilling trout.
