Nestled in Shimizu Keiryu Park in Chiba Prefecture, lies the enchanting Kameiwa Cave, attracting a multitude of visitors with its awe-inspiring beauty. The romantic and luscious natural surroundings are reminiscent of the idyllic scenery seen in films produced by Studio Ghibli. If conditions are right, you can witness a truly remarkable sight – the reflection of the cave and its surroundings in the water forming an enormous heart shape. It may surprise you to know that Kameiwa Cave is not a natural formation, but rather an artificial one created around 1660 for the purpose of supplying irrigation water to the nearby rice fields. The technique used for this purpose is called “川廻し – Kawa-mawashi,” and the locals often refer to it as the “Kawa-mawashi tunnel.” Interestingly, one of the rocks inside the cave resembles a turtle (亀 – kame), giving the cave its name, Kameiwa.
The Kameiwa Cave is nestled among verdant trees and undergoes seasonal transformations. The summer season adorns the area in luxuriant greenery, while autumn showcases the spectacular vibrancy of crimson leaves. However, what distinguishes Kameiwa Cave is its renowned reflection effect.
Have you ever heard of the heart-shaped reflection created by sunlight in a cave? It’s a pretty cool phenomenon! You might be wondering when and how you can witness this unique scene. Well, to see it, you’ll need to wait for the right time when the sunlight enters the cave just so, casting a shadow that forms the shape of a heart on the water’s surface. Cool, huh?
To have the best experience, it is recommended to visit this place in either March or September, particularly a few days before the equinoxes. The weather should be sunny and clear with a slightly humid atmosphere. It is also crucial to ensure that there is minimal to no wind. Fortunately, it is not generally windy around the cave, so you need not be overly concerned about this factor.
While you might not be able to snap the perfect heart-shaped photo, you’ll still be in awe of the breathtaking scene when the sunbeams filter through the cave. If you’re looking to get the best angles for your pictures, consider taking a stroll down the river – just make sure you’ve got some waterproof shoes or sandals on hand!
