At Suimeikaku, the closest lakeside onsen inn to Lake Shikotsu, enjoy our open-air baths.

We offer two unique private open-air baths, each with a gazebo and its own distinct charm: the stone-built and the cypress-built baths.

Both baths allow you to relax in high-quality natural hot springs while sunlight filters through the trees, illuminating the water’s surface, and you gaze upon the majestic blue Lake Shikotsu. Experience a moment of tranquility without any interruptions.

The Standard Twin boasts a warm color scheme, creating a gentle and soothing space. While soaking in the natural onsen, you can gaze at the majestic lake through the bedroom window, refreshing both body and mind. Relax in a chair and enjoy the serene moments as you take in the view of Lake Shikotsu through the trees.

The Deluxe Twin offers an exclusive view of Lake Shikotsu through a large window in the bathroom. Surrounded by majestic nature, you can enjoy a liberating and leisurely soak in the onsen, providing a stark contrast to the busyness of daily life and allowing time to flow gently. At night, create cherished memories with your partner as you gaze at the serene and quiet Lake Shikotsu.

The Japanese-Western Special Room, blending Japanese and European styles, exudes a modern yet nostalgically tranquil atmosphere for adults. This special room offers a panoramic view of Lake Shikotsu from anywhere in the room. Witness the mystical moments when the golden sunset reflects off the lake's surface. Whether in the morning or evening, the ever-changing, enchanting scenery of Lake Shikotsu will envelop you. Savor these breathtaking scenes to your heart's content.
