San Joaquin Cotton Blanket

San Joaquin Cotton ・ Rapier-Loom Weaving ・ Imabari, Japan

Wrapped in Comfort — A Soft, Fluffy Retreat
Drape it over a sofa or beside the bed, and it looks right at home — a blanket woven with authentic Imabari towel craftsmanship. The moment it touches your skin, it's light and airy, wrapping you in a soft, cloud-like warmth. Pile covers the surface generously, edge to edge, so every inch feels smooth to the touch, and the long, air-filled loops carry a plush softness that's hard to put down. From children to adults, being wrapped in it head to toe brings out an unguarded smile — the kind of relaxation this blanket is made to deliver.

A moment of relaxation, wrapped in soft warmth

Its raw material is San Joaquin cotton — a pure white, premium-grade cotton grown in California, USA, named for the San Joaquin Valley where it's cultivated. Spun with almost no twist, the yarn keeps the fiber's natural fluffiness and soft texture intact. Because the fibers are long, the cotton also absorbs moisture beautifully, and its shedding rate is just 0.065% — gentle enough for even a newborn's delicate skin.

Use it as a lap blanket, drape it over your shoulders, keep it at your bedside, or wrap up in it for a nap — however you reach for it, it's ready to become a quiet companion for your moments of rest.

Passion Passed Down, Woven From Cotton Sourced Around the World
Ehime Prefecture's Imabari is known across Japan as the country's foremost towel-making region — the name "Imabari Towel" carries a level of trust few textile names can claim. Founded in 1963, Watanabe Pile has spent more than sixty years in this town, carrying forward the passionate craftsmanship of its founding generation in pursuit of "a towel the world has never seen."

What sets Watanabe Pile apart is an intimate knowledge of cotton grown around the world, and a commitment to drawing out the individual character of each variety. By closely studying the fiber properties of each cotton and developing its own approach to twisting and weaving, the mill produces a range of towels that mass production could never replicate.

Studying twist and weave to bring out the character of each cotton

Most mills source their cotton through a single trading company, but Watanabe Pile works with several, so each towel can draw on the particular qualities of cotton from different countries. The family also visits cotton fields and spinning mills in person, seeing for themselves the faces and conditions behind each harvest. Handing a finished towel back to the people who grew the cotton, they say, is part of the craft itself — a conviction that ties together cotton grown across the world with the weaving skill of Imabari.

Toshio Watanabe, who led the mill before the current generation, was a self-declared "towel maniac" — every business trip abroad meant returning with a suitcase full of towels to study, towel-making woven so thoroughly into daily life that the two were inseparable. Today, his wife Chitose, his elder daughter Arisa, and his son Fumio carry that spirit forward, working closely with the rest of the team to weave, with care, towels made to move the hearts of everyone who touches them.

Made to Feel Its Best After You've Used It
This blanket is woven on a rapier loom — a mid-speed machine, gentler in motion than the high-speed looms more commonly used in Imabari. That slower pace puts less strain on delicate yarn, and the extra time spent weaving produces a fuller, more even texture with real depth. Towel-making also involves more than ten separate steps, from preparing the yarn to the final finish. In Imabari, most of these steps are handled by different specialists, each stage carrying the hand-work of a skilled craftsperson.

Woven slowly and carefully for an even, considered texture

Amid all this painstaking work, what matters most to Watanabe Pile is a simple wish: that a towel should reach its best condition after it enters daily life, not before. A towel is an everyday object, found in every home — which is exactly why the more it's used, the more its comfort deepens and its softness grows. This is a blanket whose true completion waits somewhere further down the road of daily use.
