🗺️ Guiyan Cave (Qingshui Stream Square)清水渓流広場（濃溝の滝・亀岩の洞窟）

In the natural park of Kisarazu City, Chiba Prefecture, there is a hidden gem known as "Kameiwa Cave." During specific months, sunlight shining into the cave reflects off the water's surface, creating a dreamy heart-shaped illusion, making it feel like stepping into a Studio Ghibli world. This phenomenon has sparked discussions on social media, leading to its rising popularity. The chances of seeing the beautiful heart shape are higher in the morning during the spring equinox in March and the autumn equinox in September. It is essential to have clear weather with no strong winds to witness this stunning heart-shaped view. Some areas near the cave are off-limits, so please be particularly cautious when sightseeing or photographing. There is a walking path near the cave, and from June to August, you can see fireflies. In autumn, the colorful leaves can be enjoyed, showcasing different scenery in each season. Additionally, not far from the cave, there is a "Lucky Bell," which is said to bring good fortune. Besides the heart-shaped cave, there are many other exciting attractions in the vicinity.

The "Turtle Rock Cave" stream, famous for its heart-shaped light reflections, is a must-visit spot. It can only be seen on clear mornings during the spring equinox in March and the autumn equinox in September. In summer, there are fireflies, and in autumn, you can enjoy the autumn leaves.
