MITSUI KEORI
Warmth from Izumiotsu, shaped by natural fibers.
From Izumiotsu, Osaka — known for blanket-making — MITSUI KEORI has crafted natural-fiber blankets since June 1952. Wool, cashmere, silk, and cotton are key materials, and the brand highlights the feel of natural fibers. Even with more labor than synthetics, the brand commits to the "natural fiber feel" that holds warmth while resisting moisture buildup. It also states a workflow of selecting raw materials, inspecting and spinning them in Japan, then finishing each piece. Through its official online store and official Rakuten shop, you can browse by material, type, and size — from blankets to pads and gauze-style layers. As a hint for selection, the "Blanket Trivia" section is also published — accompanying seasonal bedding choices from the maker's perspective.
Why We Love It
Enjoy the differences by material. In winter, layer a merino wool or cashmere blanket over your bedding for another warm layer. For skin contact, try a cotton blanket or a gauze-style layer for a lighter feel. If you want warmth from below, add a pad-style blanket at the foot of the bed. Many models are labeled washable, so switching your seasonal set can feel easy and fresh. When in doubt, browse the "Blanket Trivia" page on the official site and choose by material-and-use compatibility.
PROFILE About the Company / Workshop
MITSUI KEORI is a blanket maker based in Kawaramachi, Izumiotsu, Osaka. Its company profile lists June 1952 as the start of the business, and the brand frames its work within Izumiotsu's blanket-making culture. Phone and fax are clearly listed, showing a straightforward maker-to-customer posture.
Across its concept pages, the brand emphasizes natural fibers. It describes comfort that holds warmth while helping moisture escape, and it openly acknowledges the extra work compared with synthetic materials. The idea is to remove what is unnecessary and let the fiber's own character shape the blanket.
Materials are a core way to choose. The site highlights wool, cashmere, silk, and cotton, and the product list features a Royal Series with names like Alashan cashmere, baby cashmere, and superfine merino lamb. You can also find cotton blankets, gauze-style options, and pad-style blankets — covering both winter and transitional seasons.
The official store describes selecting raw fibers, inspecting them in Japan, spinning the yarn, and finishing each blanket. A store notice mentions the official online store opening in 2015, and the inquiry page shows the official contact email ([email protected]). There is also a tips section to help you match material and use to your own sleep style.
From Izumiotsu, Osaka
Headquartered in Kawaramachi, Izumiotsu. Founded in 1952, the company describes over six decades of blanket making in a town known for the craft. The steady know-how of the region supports the comfort you feel every night.
Natural fibers, kept honest
The concept pages put natural fibers at the center. They highlight warmth that stays in while moisture is less likely to linger, and they acknowledge the extra labor compared with synthetics. That effort is directed toward a cleaner, more natural feel.
Series you can choose by material
The lineup spans wool, cashmere, silk, and cotton. The product list introduces a Royal Series, including Alashan cashmere, baby cashmere, and superfine merino lamb. Beyond top blankets, you will also find pads, cotton blankets, and gauze-style layers for warmer seasons.
Inspected and spun in Japan
The brand notes a process of selecting fibers from each origin, inspecting and spinning them in Japan, then finishing the blanket. The official online store (announced as opened in 2015) ships directly and lets you filter by size, type, and material — helpful when you are replacing just one piece.
