[2025 Kimitsu Attraction] Travel Guide for Nomizo Waterfall and Kameiwa Cave (Updated May)

Only a day-trip's distance away from Tokyo, on the Boso Peninsula of Chiba Prefecture, is Kameiwa Cave. Only in the past few years, the beauty of this cave has captivated the hearts of many travelers. The cave is not only covered in lush nature reminiscent of a Studio Ghibli movie; it also has a certain "heart-shaped" scenery that shows itself under the right conditions. This scenery was what went viral on social media, and made Kameiwa Cave an immediate hit with tourists in Japan. With images, this article will introduce the picturesque Kameiwa Cave, its best views, and things to do in the area. Kameiwa Cave is located in Shimizu Keiryu Park, in the city of Kimitsu, Chiba Prefecture. The public park is equipped with a nice walking trail that can be taken to explore the park. Kameiwa Cave is actually a man-made cave. Around 1660, the cave was made to serve as a tunnel to help with irrigating nearby rice fields.

Kameiwa Cave (Nomizo Falls) Kameiwa Tunnel (Nomizo Falls) Kameiwa Tunnel is a man-made irrigation channel to divert water to agricultural areas in this area. A long time ago, the waterway you see here was not a natural waterfall. Today, we can call this area in many ways, such as Kameiwa Tunnel or Nomizo Falls. The special thing about this place is that if you come at the right time, you will see the morning sunlight pass through the tunnel and reflect on the water surface in the shape of a heart, which is amazing. #TravelJapan #japantrip #chiba #tokyo #GetDiscountsWithoutLuck

The Nomizo Falls and Kameiwa Cave in Kimitsu, Chiba Prefecture, are fantastical spots that make you feel as if you have wandered into the world of Ghibli. In particular, the moment when the morning sun shines into the cave and reflects on the water's surface, creating a heart-shaped light, has become a hot topic on social media! The best time to see this heart-shaped light is early in the morning (around 6:30-7:30) during the equinox in March and September! After enjoying the beauty of nature, take a break at the nearby hidden soba restaurant SOBA ABIRU. With a log cabin-style exterior, the interior is a relaxing space where you can feel the warmth of wood. The handmade soba noodles made with domestic buckwheat flour are served with locally produced ingredients, and the duck soba and tempura soba are particularly popular. 📍Basic information (check the website for the latest information) ✴︎Nomizo Falls and Kameiwa Cave ・Address: 1954 Sasa, Kimitsu City, Chiba Prefecture ・Access: 33 minutes by car from Kisarazu East IC on the Ken-O Expressway ・Fee: Free ・Opening hours: 24 hours (*Early morning visit recommended) ・Parking: Approximately 130 regular cars (free) ✴︎SOBA ABIRU ・Address: 1654-1 Sasa, Kimitsu City, Chiba Prefecture ・Access: 5 minutes by car from Nomizo Falls ・Opening hours: 11:30-15:00 (closes when soba runs out) ・Closed: Thursdays (irregular holidays) ・Parking: Over 10 spaces available #Spring 0 yen trip

Noumizonotaki Falls is located in Shimizu Keiryu Hiroba, Kimitsu City, Chiba Prefecture. This small waterfall became one of Chiba Prefecture's most popular tourist attractions after a photographer posted a photo of it on Instagram. The official name of Noumizonotaki Falls is Kameiwa Cave. Long ago, it was an artificial tunnel made to draw water to rice fields, and it is said that it was given this name because a rock resembling a turtle was discovered in the tunnel. (The original "Noumizo" falls is located in the opposite direction.) The light beams shining into the tunnel are truly fantastical, and it has become known to many fans as being "Ghibli-like." The most popular time of the year for Nomizo Falls is when the light beams shining into the tunnel form a heart shape. For seven days, including three days before and after the spring equinox and the autumn equinox, many tourists flock to the area as the "heart that brings happiness," and it has now developed into an overtourism problem. It is a spectacular view that is worth seeing at least once, while keeping to the rules.
