A bed to come home to: Harunobu Murata designs BRAIN SLEEP’s new silk-led Premium range
Charcoal, deep navy and taupe bring the HARUNOBUMURATA designer’s eye to pillows, two comforters and sheets. Japan’s preview starts November 4; general sales begin November 18, with some deliveries in early December.
At the end of a busy day, another completed task may matter less than a bed that invites you to stop. BRAIN SLEEP’s first Premium range brings in HARUNOBUMURATA designer Harunobu Murata to consider fabric against skin, drape and bedroom colour together. Announced October 30, it goes on advance sale at Isetan Shinjuku from November 4.
This is more than a pillow in a new colour. Four product categories cover a pillow, winter comforter, all-season comforter and mattress sheets, with Murata overseeing materials, colour and details. Charcoal, deep navy and taupe offer a coherent, quieter look rather than a bedroom arranged purely for display.
Silk and lyocell bring clothing’s tactile qualities to bed
Silk’s sheen and drape and finely brushed lyocell are central materials. The pillow cover uses 100% silk knit, as do the sheets; the winter comforter’s outer fabric is 100% lyocell, finished roll by roll at an Izumiotsu workshop. These are different roles and materials, not a set that can all be called one kind of silk duvet.

Murata connects the feeling against skin with details and the bedding’s presence in a room. Readers can start with a preferred colour, texture and existing bedding rather than replacing everything at once. The images present the brand’s products; they are not this publication’s account of sleeping with them.
Separate the pillow structure from the two comforters’ purposes
The Premium pillow enlarges the standard-line design and uses a nine-stage firmness gradient with a silk cover. Its Japanese price is ¥66,000. Zoned support is the brand’s design approach, but sleep position and preferences differ; neither price nor firmness zoning proves universal suitability or treatment for neck discomfort.
Perfect Warm Premium uses Carbonano Down filling and a finely brushed lyocell shell, priced at ¥220,000–¥418,000. The all-season option is ¥165,000–¥308,000, using PCM temperature-control material and a silk shell. Match prices to size and model; the starting price is not every size’s price, and brand temperature-and-moisture claims are not our measurements.
November previews, with some deliveries in December
The Isetan Shinjuku main building’s fifth-floor preview runs November 4–17. General sales start November 18 at 10:00 through the official site and direct stores in Tokyo Yaesu and Osaka Umeda, Japan time. Some products are scheduled for delivery in early December, so ordering and receiving dates are distinct.
Further pop-ups run December 2–22 at Ginza Mitsukoshi and December 2–28 at Hankyu Umeda. Sheets cost ¥60,500–¥104,500. Check mattress size, care and delivery terms before choosing. Attractive bedding is a lifestyle purchase, not a guaranteed treatment for insomnia or skin and hair concerns; simultaneous Taiwan sales have not been verified here.
