Metos' Proposal for the 'Ultimate Private Sauna'

Each villa is a luxurious space of approximately 150㎡. Metos has meticulously produced a sauna environment down to the smallest detail, allowing guests to fully enjoy it without disturbance.

Authentic Finnish Sauna and Self-Löyly

Each independent villa is equipped with Metos' proud Made-in-Japan private sauna. The sauna room, enveloped in the warmth of wood, allows for self-löyly, and aroma oils (rento) for löyly are also provided. Guests can experience a personalized sauna with comfortable steam and fragrance enveloping their entire body.

Cold Plunge with Chiller and Open-Air Bathing

For cooling down after the sauna, all rooms are equipped with an outdoor cold plunge with a chiller (cooling unit). The terrace, where guests can directly experience the nature of Izusan, offers a blissful open-air bathing space.

Post-Sauna Wellness Experience

In the private garden, guests can enjoy a BBQ and bonfire experience reminiscent of Finland, the home of saunas, and a relaxation space created with a 120-inch compatible projector and screen. Guests can enjoy an extraordinary wellness experience.

All-Inclusive Access to Services Provided at the Main Building

At the main building's large hot spring bath with an open-air bath, Metos' long-loved sauna facilities have been renovated in line with the facility's rebranding.

Guests can also use the facilities and services of the main building. This facility allows guests to enjoy both the privacy unique to a villa and the elegance of a hotel.

About Metos' Bathing and Sauna Business

Triggered by the construction of a sauna in the athletes' village for the 1964 Tokyo Olympics, Metos quickly began the construction and sales of saunas in cooperation with overseas partner companies.

We provide consistent services from equipment diagnosis, equipment design, and construction to maintenance.

From an early stage, we have also focused on business development that considers SDGs and the environment. As professionals involved in 'housing' among 'clothing, food, and housing,' we also propose comprehensive bathing businesses that can contribute to the realization of a sustainable future for people.

In addition to its bathing and sauna business, Metos also operates two other businesses: a fireplace and wood stove business, which handles wood stoves, gas objets, and custom-made fireplaces, and a welfare business, which handles universally designed care bathtubs and similar products.

Metos will continue to spread sauna culture, contributing to the health of mind and body through high-quality facilities.
