Otatomarinuma Pond
A Mirror of Mt. Rishiri in a Forest Paradise
Discover the serene beauty of Rishiri Island’s largest pond, where Mt. Rishiri reflects perfectly on calm emerald waters, surrounded by a lush spruce forest.
Located in the southeast of Rishiri Island, Otatomarinuma Pond is a peaceful gem nestled within a deep, ancient forest. As you step onto the shore, you are gently embraced by the crisp, refreshing scent of Sakhalin spruce and the pure, clean air. On clear days, the mirror-like surface of the water captures the majestic peak of Mt. Rishiri, creating a striking contrast between the deep greens of the trees and the brilliant blue of the sky.
A flat, well-maintained walking trail circles the pond, allowing for a relaxing 30-minute stroll. Along the path, the soft chirping of wild birds and the cool breeze brushing against your cheeks help you leave everyday stress behind. From June to July, the nearby Numaura Marsh—a designated natural monument of the town—comes alive with vibrant purple irises. It is a place to pause, breathe, and fully immerse yourself in the vital energy of Rishiri Island.
