[Exquisite Rest] Why "Silk Touch" made from wood changes the quality of your sleep

Even though we are busy every day, are you able to experience a truly comfortable sleep?

"Ever since I switched to these pajamas, I've started looking forward to the evenings." We've received such happy comments from many of our customers. Why are our pajamas so beloved? The secret lies in the blessings of nature and the invisible attention to detail of our artisans.

DEEP SLEEP: "Comfortable rest" through innovative technology

All processes for this collection, from thread development to sewing, are carried out in Japan.

• 100% plant-derived Japanese and Chinese herbal power. A unique blend of wild Japanese plants, including mugwort, persimmon leaves, and Japanese knotweed. The power of nature is locked deep within the fibers without relying on chemicals.

• Science proves "good sleep" and "beauty": Skin moisture increases by an average of 14% (up to 26%) while sleeping It also helps lower stress levels and stabilizes your heart rate, leading to a deep state of relaxation.

• The semi-permanent comfort ingredients are baked into the fibers themselves, so even after repeated washing, the effects will last as long as the garment is in use.
