Mitsuuroko Co., Ltd. (Headquarters: Chiyoda-ku, Tokyo; President: Kohei Tajima), a consolidated subsidiary of our group, will grand open its relaxation facility 'Yokohama Natural Hot Spring SPA EAS' (hereinafter 'SPA EAS') on Tuesday, July 28, 2026.
As a new concept for the facility, we are introducing 'Wellness Quest,' offering everyone a 'healing journey' that takes them one step away from their daily routine.
The approximately 3,000㎡ facility, spanning two floors, will be reborn as a more comfortable and sophisticated space, retaining its natural hot springs flowing from underground and a wide variety of baths, while adding a new sauna with a giant screen and an open relaxation area filled with natural light.
Furthermore, the age limit for use will be expanded from the conventional 18 years and older to 16 years and older, allowing even more people to enjoy the facility.

■ Renovation Concept
'Wellness Quest - A 'healing journey' that takes you one step away from daily life, even without going far.'
While located in the city of Yokohama, we have reconfigured the space and experience with the concept of a 'healing journey' that allows you to step away from daily life and restore your mind and body.
We aim to contribute to a wellness experience that gently unwinds your mind and body, allowing you to return to your daily life with a positive outlook.
■ Introduction of Video Projection Sauna - SAUNA IMMERSIA
'IMMERSIA' is a name inspired by 'Immersion.' A new sauna where men and women can enjoy together will be born, featuring a wide screen that fills the entire field of vision. You can enjoy a new sauna experience, slowly sweating while enveloped in visuals.
In addition, the popular 'heat wave' event will be integrated with powerful video projections, creating an even greater sense of unity than before.
A spacious cool area has also been newly established to prepare your mind and body after sweating. Take a deep breath while gazing at the rich greenery surrounding the building and enjoy a special time enveloped in a pleasant coolness. You can relax comfortably to complete your sauna experience.
■ New Lounge Area - VALO TERRACE
The lounge area has been completely renovated, transforming into a more comfortable and exciting space for relaxation, reading, and light meals. As its name 'VALO' - meaning 'light' in Finnish - suggests, you can spend your time as you wish in an open space filled with soft light.
■ SPA EAS × ID UNITED ARROWS Collaboration In-house Wear
In conjunction with the renovated space, the in-house wear will be renewed. 'ID UNITED ARROWS,' a uniform label developed by UNITED ARROWS Ltd., has designed the original.
It will comfortably enhance your time spent in the healing hot spring space and luxurious spa experience.
The design of the in-house wear will be unveiled at a later date.
■ Authentic Japanese Dining Brand, First-time in a Hot Spring Facility, Introduces Japanese Modern Dining
In the dining area, BYO Co., Ltd., which operates various business formats such as 'Washoku Sake En,' 'Obanzai Aburiyaki Sake Nana,' and 'Obon de Gohan,' will open a new brand restaurant 'Miwane' and cafe 'Miwane Cafe.'
The restaurant will offer a wide range of dishes, primarily set meals that allow you to enjoy a balanced main and side dishes, as well as comforting and hearty 'sauna meals.' You can enjoy a relaxing meal from lunch to dinner.
Furthermore, the restaurant can be used by those who are not entering SPA EAS.
■ Enhanced Treatment and Body Care
The treatment area has been completely refreshed, offering a diverse range of specialized menus. You can choose the optimal menu according to your physical condition and mood on the day, including body care, Thai health massage, aesthetics, and body scrubbing. With a space design that emphasizes privacy, we provide a treatment experience that soothes the mind.
■ Introduction of Smart Entry/Exit System
With the introduction of automatic reception machines and automatic payment machines, you can smoothly use the facility from entry to payment. Payments will be completely cashless.
Charges for dining and treatments within the facility will be consolidated and charged to your IC key, so there is no need to take out your wallet inside the facility.
■ SPA EAS Official LINE Start & Countdown Project Held
Prior to the opening, an official LINE account has been opened. Future updates will be announced there.
