A giant heart shape can be formed by Kameiwa Cave and its reflection on the water’s surface at the right moment.
Introduction to Kameiwa Cave
Kameiwa Cave is located within Shimizu Keiryu Park in Chiba Prefecture, known for its breathtaking beauty that mesmerizes countless visitors. The nature here is reminiscent of the lush and romantic scenery in Studio Ghibli films. Especially in suitable conditions, you can witness a miraculous “heart shape” formed by the reflection in the water.
In fact, Kameiwa Cave is an artificial cave. Around 1660, the cave was created to supply irrigation water to nearby rice fields. The irrigation technique is called “川廻し – Kawa-mawashi,” and some locals refer to the cave as the “Kawa-mawashi tunnel.” The name Kameiwa comes from one of the rocks that resembles a turtle (亀 – kame) inside the cave.
Reflection heart – the famous scene of Kameiwa Cave
Kameiwa Cave is surrounded by lush green trees. The scenery here changes with the seasons: in summer, the area is covered in greenery, while in autumn, you can admire the brilliance of red leaves. The most remarkable feature of Kameiwa Cave is the reflection it creates.
At the appropriate time, sunlight shines into the cave and creates a heart shape from the shadow reflected on the water’s surface. So, what are the specific conditions to witness this unique scene?
First, you should come here in the early morning of March or September, or a few days before the spring equinox or autumnal equinox.
Second, the weather must be sunny and clear, with a little moisture in the air.
Finally, it is essential to have little or no wind. The area around the cave is not usually windy, so you don’t need to worry too much about this.
Even if you cannot capture the heart-shaped image, you will still be welcomed by a magnificent view when the sunlight shines through the cave. You may want to walk down the river to get suitable photo angles, so be sure to prepare waterproof shoes or sandals.
