ichinomiya, aichi prefecture, japan | spring 2026

Driving the quiet backroads of Ichinomiya in Aichi Prefecture, Japan, it becomes hard to ignore the recurring vernacular of small shed roof warehouses clad with corrugated steel and high clerestory windows - once you recognize the shape of these structures you begin seeing them everywhere. They are emblematic of a bygone era as many are now defunct, but there are still a few independent small mills continuing the tradition of wool weaving that was established in the late 19th century after the region shifted away from producing cotton textiles. 

Located in the heart of the Bishu region, Ichinomiya is recognized as one of the world's leading premium wool textile producing areas alongside places like Biella, Italy and Huddersfield, UK - all sharing a relationship to local waters that aided in wool production. For Ichinomiya, the Kiso River has long provided clean, soft water, ideal for washing, dyeing, and finishing wool textiles.

Founded in 1964, Yamaguchi Keori features all the characteristics of the small-scale Bishu weaving operations that have survived the decades of shifting landscapes in Japan’s textile industry. Mr. Yamaguchi was 20 years old when he started the business, and primarily worked alone with less than a dozen looms, until his son joined him 30 years ago. The pair continue to manage a consistent output of some of the most beautiful textiles we’ve had the pleasure and privilege of working with. 

In the weaving mill attached to their house, the iconic roof pitches were designed to let in a maximum of natural light from above. Both the house and the mill open onto a courtyard garden, providing the central space between work and home. Next door sits a small but immaculately cared for Buddhist temple, offering a unique balance to the ageing mill with its exquisite patina and open windows transmitting the deep hum of vintage power looms.
