Nestled in the mountains of Okutama, Lake Shiromaru is a tranquil spot where emerald-green waters reflect the surrounding forest. Walking paths follow the lakeshore, and visitors can also enjoy canoeing and fishing. Each season brings new beauty—soft, ethereal light over the lake makes every visit a fresh encounter with nature’s calm.
