Experience the "Stanford Method of Best Sleep" with a new hotel stay proposed by The Prince Gallery Tokyo Kioicho

Event Date:2021.03.01-05.10
Feb 25, 2021
The Prince Gallery Tokyo Kioicho (Address: 1-2 Kioicho, Chiyoda-ku, Tokyo) will be selling the "Good Sleep" accommodation plan, developed in collaboration with Brain Sleep Co., Ltd., from March 1 to May 10, 2021, to experience a quality night's sleep.


Sleep takes up one-third of our lives. According to a Brain Sleep survey, sleep quality has declined and people are becoming more nocturnal due to changes in working styles, such as working from home. Therefore, we have created an accommodation plan that combines Brain Sleep's sleep method with carefully selected, soothing content that stimulates the five senses based on IT technology and high-quality items selected by the hotel, allowing you to experience the best possible sleep. Guests can enjoy content and the hotel's carefully selected nighttime items to support quality sleep, including pillows inspired by the "Stanford Method for Best Sleep," "WABARA," an original variety of rose developed by Japan's leading rose breeder, Keiji Kunieda, which enhances relaxation, "Endel," a mindfulness app that uses AI to generate healing sounds optimized for each individual, and "IELU/cado," an ultrasonic humidifier that purifies the mind and space.

As self-restraint continues, this accommodation plan, which allows guests to experience safe and comfortable sleep, was created with the hope that as many people as possible will be inspired to face the next day and live healthy and fulfilling days.

Sleep content carefully selected based on the Brain Sleep method
1. "Brain Sleep Pillow" - a hybrid pillow that "puts your brain to sleep"
This pillow, inspired by "The Stanford Method for the Best Sleep" (by Seiji Nishino of Brain Sleep Co., Ltd.), cools the brain with its outstanding breathability and invites deep sleep. It's a hybrid pillow with low and high resilience that conforms to the shape of your neck and head.


2. "WABARA"
"WABARA" is an original rose from Rose Farm KEIJI, located on the shores of Lake Biwa.
This original variety was developed by Keiji Kunieda, one of Japan's leading rose breeders. This time, we're focusing on the aromatic component known as "Tea Rose Element," which has a particularly relaxing effect. We've prepared a "WABARA" bouquet, a vase of the particularly relaxing "Yui" variety, and a bottle of bio-rose water for your room.

(1) A "WABARA" bouquet that prepares you for sleep with the power of a fresh scent. The exquisite scent of the "Tea Rose Element" soothes your mind and body before you fall asleep. Enjoy a relaxing time with the city night view unfolding before your eyes.


(2) "Yui," a bio-rose water from "WABARA" made from 100% rose petals. After your bath, add 1-2 drops of bio-rose water to mineral water to hydrate. "Yui," a rose biowater extracted only from the petals, has a tea-like fragrance that will lull you into a restful sleep.


3. "Endel," the healing technology that's garnering global attention
"Endel," a mindfulness app from Berlin, is loved by over 2 million users in 136 countries around the world. AI generates healing sounds that are optimized for each individual in real time, supporting relaxation, good sleep, and concentration.


4. "IELU/cado" ultrasonic humidifier purifies and hydrates your mind and space.
The ultra-pure electrolyzed water "IELU" and the "cado" ultrasonic humidifier maintain a comfortable temperature while sterilizing the space. Their high permeability also keeps your skin moisturized.


*In addition to the above, we also offer bath salts made with Seto Inland Sea salt from the sleep aroma brand "And Good night," which will enhance your bath time, as well as Dr. Air's 3D massage roll and 3D conditioning ball mini, which will help you condition yourself for a smoother sleep, to create a luxurious moment before bed.
