Top Things to See at Lake Chūzenji
Scenic Spot: Lakeside Walks
With a shoreline of about 25 kilometers, Lake Chūzenji is expansive—and simply strolling along the lakeside lets you fully enjoy its natural beauty.
Viewpoints and benches are scattered along the shore, and it’s recommended to relax while taking in the clear lake water and the grand silhouette of Mount Nantai (about 2,486 meters).
From spring through autumn, you can also enjoy activities such as canoeing, boating, and cycling.
Kegon Falls
Kegon Falls, located at the lake’s outlet, is one of Japan’s Three Great Waterfalls and is a powerful sight to behold.
With a drop of about 97 meters, the waterfall shows different charms each season—snowmelt in spring, autumn foliage, and even a frozen appearance in winter.
By taking the paid elevator down to the observation deck, you can view the falls up close and enjoy their beauty along with the thunderous sound of rushing water.
Italian Embassy Villa Memorial Park
Italian Embassy Villa Memorial Park on the shores of Lake Chūzenji is a facility that restores and opens to the public a historic building once used as an Italian embassy villa.
The building features a distinctive design using cedar bark arranged in a checkered pattern, beautifully blending with the lakeside nature.
Inside, you can glimpse the villa’s history and the culture of the area as an international summer resort, and the terrace view overlooking the lake is spectacular.
British Embassy Villa Memorial Park
Near the Italian Embassy Villa is also the British Embassy Villa Memorial Park, where a villa built in 1896 (Meiji 29) by Ernest Satow as a private mountain retreat has been restored.
This site is also prized for its beautiful lake-view location, and inside you can learn about British culture and the area’s history as an international resort.
On the second floor café space, you can enjoy scones and tea while taking in the breathtaking lake scenery.
In some periods, a combined ticket with the Italian Embassy Villa Memorial Park may be available.
