Sonata is another annex that strongly retains the spirit of Japanese tradition, and refers to a performance style that unfolds like a story, divided into movements. Located in a quiet area a short distance from "Canon," it is a compact annex suitable for gentle harmony among small groups.

Fuga, as its name suggests—a musical form without a fixed structure, freely modulating and developing—is a "playground for adults" where you can enjoy yourself unpretentiously in a private space. Like your own private bar, you can freely serve each other drinks, and casually enjoy table tennis, darts, and karaoke. Spend a special night that will bring you closer to your loved ones.

Lento refers to the semi-open-air bath located in a separate building. The name means "relaxed, quiet, and slow," and it is a bathroom where you can spend a particularly quiet and luxurious time amidst the rising steam, with a different atmosphere from the melodies woven in the other buildings.

The sauna is a circular building covered in wood, and inside you'll find a simple yet warm space where you can relax.
You can enjoy a private sauna experience while gazing at the bamboo grove through the large windows.
Next to the sauna is a black pool that beautifully reflects the surrounding bamboo grove.
After warming up in the sauna, you can enjoy a refreshing cool-down in the pool, experiencing both relaxation and rejuvenation at the same time.

*Please note that the swimming pool may occasionally be unavailable due to temporary cleaning or maintenance (especially during the summer).

In the center of the main garden, where a cherry tree stands as a symbol, there is a bonfire placed alongside a comfortable bench, allowing you to spend a peaceful moment while watching the soothing flicker of the flames.
