Located in northeastern Iiyama, this mysterious lake is surrounded by mountainous terrain.A favorite location for photographers, it is particularly lovely in spring, when cherry and canola blossoms are in full bloom. Because the lake is heart shaped, it's also known as a popular destination for couples. The periphery of the lake is an easy walk, and the lake can also be crossed by boat. On the far shore, statues honor the 7 Deities of Good Luck.During the August fireworks festival, fireworks are launched from boats on the water, and explosions echo in the surrounding mountain ranges.On the shores of the lake, the Bunka Hokuryukan facilities include hot springs baths, a collection of artifacts from late Edo Period nobility, and the Keyaki Cafe. This is a great place for visitors who want to enjoy the best of the region's natural environment.
