A riverside villa nestled in the valley

Yoro Valley is renowned as one of the most scenic valleys in the Kanto region and a famous spot for autumn foliage.

On its banks, a newly constructed villa composed of two single-story buildings has been born.

The two buildings, standing side by side on the same property, are both independently available for exclusive rental.

With identical layouts and facilities, both villas can be booked together for larger groups.

Enjoying the valley’s four seasons

Architectural beauty by Gen Inoue, harmonized with nature

The design was led by architect Gen Inoue, who has won numerous awards both in Japan and abroad.

With meticulous attention to the angle that best captures the flowing river, expansive glass surfaces and high ceilings allow abundant natural light to flood the interior.

The seamless connection between indoors and outdoors creates a space that blends with the landscape.

Every detail of the villa is thoughtfully designed to enrich your stay.

A relaxing riverside retreat

The majestic Yoro River flows directly in front of the villa.

This rare location allows you to reach the riverbank in just a few steps.

From the open, window-surrounded interior, you can enjoy panoramic views of the river,

experiencing its changing beauty from morning to night up close.

A day spent by the water slows time and soothes the soul.

Barrel sauna for deep relaxation in the valley

A barrel sauna with views of the Yoro River’s stream has been installed.

Relax inside, warmed by the Helo-brand electric stove, while gazing out the window.

The gentle sway of trees and the sound of flowing water guide you into deep 'recovery'.

After the sauna, cool down in the cold plunge pool, then unwind on the deck with open-air bathing.

The refreshing breeze gently cools your heated skin.

A special sauna experience where your five senses gradually unwind in serene tranquility.
