Nestled within the serene Shimizu Keiryu Park in Chiba Prefecture lies the captivating Kameiwa Cave. Its stunning beauty has entranced numerous visitors, with its surroundings resembling the enchanting scenery often depicted in Studio Ghibli films. One of the most remarkable sights that can be witnessed here is the formation of a colossal heart shape through the cave’s reflection on the water’s surface.
