Tucked away in a hidden valley, you'll discover one of Kamakura's most unique shrines by first passing through a mysterious rock tunnel. Inside, the air feels sacred and you're surrounded by cliffs. The main attraction is the cave where you can wash your money in the sacred spring water, a ritual believed to multiply your wealth. It's about a 20-25 minute walk from Kamakura Station, with a steep hill just before you arrive, so wear comfortable shoes for the journey.
