New Era of 'Sleep Wellness': Limited 'One Room Per Day' Suites Featuring nishikawa's Latest SLEEP TECH® Arrive at The Capitol Hotel Tokyu

Nishikawa Co., Ltd. (Headquarters: Nihonbashi, Chuo-ku, Tokyo; President: Masahiko Takeuchi) announced that its bedding and amenities have been selected for the 'Sleep Wellness' stay plan at The Capitol Hotel Tokyu (Chiyoda-ku, Tokyo; General Manager: Koji Shimura), which will be available starting Wednesday, May 27, 2026.

In recent years, the concept of 'wellness destinations'—where guests seek to maintain health and recover physically and mentally through their stay—has become a global trend in the luxury hotel market. In response to this growing demand, Nishikawa has pooled its expertise, combining traditional craftsmanship with the latest sleep science. Moving beyond the standard of a 'comfortable bed,' we have realized a new sleep environment based on scientific evidence within the serene space of the hotel.

This plan is sold as a 'one room per day' package to provide a special sleep and recovery experience. The room is equipped with 'Healthyon,' a certified medical device mattress that addresses daily discomfort through thermal and potential therapy. The thermal therapy promotes blood circulation with gentle warmth, while the potential therapy helps improve headaches, stiff shoulders, and insomnia, supporting fatigue recovery and easing physical and mental tension. Additionally, the 'Air 4DX' pillow from the [Air] series, favored by many top athletes, is included to reduce strain on the neck and shoulders with its enveloping fit. For the duvet, we have introduced the high-quality 'nishikawa Down' duvet, which is fluffy, lightweight, and offers excellent heat retention and moisture permeability, creating an ideal sleep environment.

Furthermore, the [Air Recovery] Sleep Tech wear, which uses special fibers to promote blood circulation and improve the quality of rest, is provided for guests to take home, allowing them to continue their wellness experience after their stay.
