Goshikinuma ponds, often dubbed the “mysterious lake,” promise to be an great experience with their captivating colors—emerald green, cobalt blue, turquoise blue, emerald blue, and pastel blue. Goshikinuma meaning "five color ponds," is somewhat misleading. The area features far more than five ponds, each likely to reveal an even broader array of spectacular colors. During fall time the ponds look more heavenly and peaceful.
