The Fuji Five Lakes (Fujigoko) in Yamanashi Prefecture are made up of Lake Saiko, Lake Shojiko, Lake Motosuko, Lake Kawaguchiko, and Lake Yamanakako.
In 2013, the area was registered as part of the UNESCO World Cultural Heritage site “Mt. Fuji: Sacred Place and Source of Artistic Inspiration”, making it a destination where visitors can experience both nature and history.
In recent years, “Fuji Five Lakes Tours” have become increasingly popular, with travelers exploring all five lakes in a single day by cycling or bus tours.
Each lake offers its own unique vantage points for photographing the breathtaking views of Mt. Fuji, while the surrounding areas are filled with hot springs, gourmet dining, and outdoor activities that make the region a must-visit.
In this article, we’ll take a closer look at the charm of the Fuji Five Lakes and introduce the best sightseeing highlights. If you want to fully enjoy the natural beauty around Mt. Fuji, read on!

Lake Saiko | A Scenic Spot in Yamanashi Home to the Legendary Kunimasu
Lake Saiko, also known as the “Maiden’s Lake,” is a beautiful body of water located at an elevation of about 900 meters. With a maximum depth of 76 meters and a surface area of 2.1 square kilometers, it is the second-deepest of the Fuji Five Lakes after Lake Motosuko. The lake is popular for fishing, especially for himemasu (sockeye salmon), and is also home to species such as smelt, eel, and bluegill.
The highlight of Lake Saiko is the Kunimasu, a rare fish once thought to have gone extinct in 1940. In 2010, Kunimasu was dramatically rediscovered here, making headlines nationwide. Today, Lake Saiko is the only place in the world where Kunimasu survives, with an estimated population of 4,300 to 11,000.
Visitors can learn more at the Kunimasu Exhibition Hall, located right by the lake, where you can observe this “miracle fish” up close. Admission is free, making it a must-visit stop during your Lake Saiko trip.
Next to the exhibition hall lies the Saiko Bat Cave, a lava cave stretching over 350 meters in length, where you can experience the wonders of nature firsthand.
On the southern shore of the lake spreads the Aokigahara Forest, offering a breathtaking view of Mt. Fuji along with the deep mystery of Japan’s natural landscapes. This makes Lake Saiko not only a place of ecological significance but also a popular destination for nature lovers and explorers alike.
