Guide
Lake Tanuki (Tanuki-ko) is a beautiful lake situated in the Asagiri Plateau at the western foot of Mount Fuji in Fujinomiya City, Shizuoka Prefecture. The topography of the area was originally formed by debris flows from Mount Fuji's eruptions approximately 20,000 years ago, and the lake was later expanded into its current form for agricultural water management. With a circumference of approximately 3.3 km, it is celebrated as a scenic spot where visitors can gaze directly at the steep, majestic silhouette of Mount Fuji. The lakeside is well-equipped with facilities, including campsites and lodging, allowing visitors to immerse themselves in nature while enjoying spectacular views.
The history of Lake Tanuki is deeply intertwined with local legends and regional heritage. Historical records mention names such as "Tanuki Chosha" and "Tanuki Jiro," linked to the families that once ruled this area. Furthermore, legends surround Prince Inryo, a member of the Southern Court, and the nearby Tanuki Shrine serves as a place of worship for him as a guardian deity. Thus, Lake Tanuki is not just a natural wonder but a site deeply connected to the local history, culture, and spiritual traditions of the region.
One of the greatest draws of Lake Tanuki is the view of Mount Fuji. Photographers from around the world gather here to witness the "Diamond Fuji"—a rare moment when the sun appears to rest perfectly on the peak of Mount Fuji—especially during clear mornings near the Kyukamura Fuji area. From mid-April to mid-May, the northern shore becomes a vibrant landscape of blooming Rengetutsuji (Japanese Azalea) and Yamatsutsuji. The lakeside also features a well-maintained cycling path, making it easy to complete a loop around the lake in about 20 to 30 minutes using a rental bike. Additionally, the area is a wonderful spot for birdwatching and observing fireflies, offering a changing tapestry of seasonal beauty.
Lake Tanuki offers a different charm in every season. In Spring (mid-April to mid-May), the blooming azaleas bring a burst of color and life to the landscape. Summer is an ideal time for camping and water-side activities, offering a refreshing escape with cool breezes. For those seeking the spectacular Diamond Fuji, clear mornings around April 20th and August 20th are highly recommended. Because the appearance of Mount Fuji and the surrounding colors change significantly depending on the time of day and season, planning your visit around specific interests is highly encouraged.
A wide range of outdoor activities are available to help you experience nature firsthand. You can enjoy a relaxing cycle around the lake using the paved paths, or try boat riding and freshwater fishing at the local boat landing. For those seeking a deeper immersion, the area offers excellent camping facilities with tent sites and bungalows, allowing you to spend a night at the foot of Mount Fuji. For more active visitors, the hiking trails leading toward Mount Chojagatake provide opportunities to enjoy elevated perspectives of the landscape.
The area around Lake Tanuki is well-served by various facilities. Kyukamura Fuji offers comfortable lodging and hot spring (onsen) services, while other nearby accommodations like Tanuki Kohanso provide diverse staying options. The area is also closely linked to nature-learning initiatives managed by the Ministry of the Environment. Nearby camping sites such as Tenkoshi-no-mori Campground and La Fontaine Vacance offer various styles of outdoor stays to suit your preference.
To enjoy your visit to Lake Tanuki, please come prepared. If you plan on cycling or hiking, wear comfortable clothing and sturdy walking shoes. For camping, bring seasonal gear and clothing suitable for temperature drops at night. Regarding payments, most facilities accept cash, credit cards, or transportation IC cards (like Suica/Pasmo), but it is wise to carry some cash for smaller local vendors. Please respect the natural environment by following rules for photography in protected areas and ensuring all trash is carried out. The lakeside roads are well-maintained, but some paths may be unpaved or uneven.
