Nomizo Falls and Kameiwa Cave represent one of Japan's most photographed natural phenomena, located in Kimitsu City, Chiba Prefecture. The site gained international attention in recent years through social media, particularly for the heart-shaped light formation that appears twice annually when sunlight passes through the cave opening and reflects on the water below.

The cave itself is a natural tunnel formation approximately 20 meters long, carved through rock over centuries by the flowing waters of Nomizo Falls. Local residents have long known about this scenic spot, but it remained relatively obscure until around 2015 when photographs of the heart-shaped reflection began circulating online. The phenomenon occurs specifically during the spring and autumn equinoxes in March and September, when the sun's angle aligns perfectly to create the distinctive shape visible for a brief period early in the morning.

Visitors to Kameiwa Cave can walk through the shallow stream that flows beneath the rock tunnel, though the water level varies by season. The surrounding forest provides a tranquil setting year-round, with lush greenery in summer and vibrant foliage in autumn. Photography enthusiasts should note that capturing the famous heart reflection requires precise timing and favorable weather conditions, typically around dawn during the equinox periods. Even outside these times, the cave and waterfall offer an attractive natural landscape worth exploring.

The site is accessible from Kazusa-Kururi Station on the JR Kururi Line, located approximately 30 minutes by car or taxi from the station. Public transportation to the immediate area is limited, making a rental car the most practical option for most travelers. The journey from central Tokyo takes roughly 90 minutes by car via the Tateyama Expressway. There is no admission fee to visit Nomizo Falls and Kameiwa Cave, as it remains an open natural site. A small parking area accommodates visitors.

What other travelers are saying about Nomizo Falls and Kameiwa Cave

Great small walk into the forest. There was a small queue into the parking lot but after that you just need to have short walk to finally see the cave and falls. The view is amazing. I think if you get the right timing of day you can take amazing pictures here. Highly recommendes for photographers. I recommend coming on a sunny day during the morning or around 3pm in the afternoon.

Came in late November on a cloudy day so the light through the cave wasn't particularly striking. Bear in mind, it's a heavily manicured cave. The autum leaves were really pretty though, with many red Chinese maple trees

Beautiful area! The cave and waterfall are stunning. Super easy walk from the parking lot.

Definitely not worth it the bus trip was 2300 each way and the nearest stop is 1.6km by foot way even though the bus continues right past front gates.. pictures of bus stop inc so you can find you way back from the wilderness.

This is quite a nice place, with a really nice board walk that will look fantastic in autumn 🍁 as the surrounding trees are maple trees. There's two paths leading to the hole in the rock, one is a light forest trail and the other is a wooden board walk. I think the hole itself is famed for when the time and sunshine is right, it will create a heart shape. Otherwise, to take a better picture of the turtle rock, you need may need to step onto some areas with water.
