Nyoshin Isoi (1883–1964) was a lacquer artist born in Takamatsu, Kagawa Prefecture, and is regarded as a leading figure in modern Sanuki lacquer art. Whilst upholding the tradition established by Gyokujiro Shogaku, he conducted in-depth research into a variety of techniques, including konjō, zonsei and chōshitsu; in particular, he significantly advanced the art of konjō, which involves creating patterns by layering coloured lacquer. He established a style that combines intricate designs of plants and birds with the elegant forms of vessels and boxes, infusing traditional techniques with a modern sensibility. In 1956, he was designated a Living National Treasure as a Preserver of the Important Intangible Cultural Property ‘Konjō’.

When viewing Isoi Nyoshins’ works, one senses the patterns emerging quietly from the deep hues of the lacquer, creating a rich sense of depth despite the flat surface. Whilst the work is meticulously detailed, the overall effect is one of calm, and the fact that the decoration is never excessive is part of its appeal. His works appear to carefully carry on the tradition of Sanuki lacquer art whilst elevating patterns and colours into refined forms. The more one looks at them, the more one appreciates the meticulous craftsmanship and the quiet dignity unique to lacquer.
