■ Not just a "yakitori restaurant"
"A restaurant that designs your physical condition for the next morning"
This restaurant offers an unprecedented new concept of a yakitori course experience designed with the purpose of "enhancing sleep quality".
- Ingredients
- Cooking methods
- Aroma
- Temperature
- Flow of the meal
Everything is linked to "sleep" and "beauty".
It is not merely a "delicious meal", but a new genre of restaurant that "designs your physical state after eating".

Japan is said to be the country with the shortest sleep duration among OECD member countries.
In modern times, it is said that about 1 in 2 Japanese people have sleep-related issues. (Sleep White Paper)
Furthermore, women sleep for a shorter duration than men.
This project was born when the representative, Saito, who had been at the forefront of the "sleep industry" for 28 years, reached the conclusion:
"To make the world 'energetic from the morning', it is necessary to integrate food and sleep."

■ The representative is a former president of a major sleep industry company, Showa Nishikawa

Representative Joichi Saito (born in 1973) has served as:
- President and Representative Director, Showa Nishikawa Co., Ltd.
- President and Representative Director, Showa Nishikawa Global Partners Co., Ltd.
- Representative Director, Sleep Improvement Academy (General Incorporated Association)
In December 2025, he resigned from all positions to fully commit to the "world of food".
This is not a simple entry into the restaurant business; it is a project where "a sleep professional changes Japan's sleep through sleep x food."
