About
In Shimizu Mountain Stream Park, a stream flows out through Kameiwa Cave into a pool below Nomizo Falls. At sunrise around March and September, light shining through the cave reflects off the water in a heart shape, which made the spot famous on social media. The mossy gorge is pretty year-round, and Nomizo Onsen is beside the park entrance.
