Maruyoshi Kosaka was founded in the Kiso area of Nagano in 1945. The Kiso region has a long and proud lacquer tradition, which in recent years has seen a decline due to an assumption that lacquerware is difficult to use and care for. Yasuto Kosaka, a traditional craftsman, dedicated himself to challenge this widely-held belief.
Succeeding his father 40 years ago, Yasuto Kosaka, who is the second-generation of the family, had been making low tables with lacquer coating by “roiro nuri”, a painting technique which gives a smooth and rich polish to the surface similar to that of a mirror. In 1994 at his atelier, he succeeded in combining glassware and urushi lacquer. Combining the warmth and fascination of urushi lacquer with the cool transparency of glass liberated the lacquerware from its traditional image.
Most of these pieces have the lacquer applied on the outer side, so that the inner side, which comes into contact with food or drink, is simply glass. The difference in durability means that these pieces can be used with metallic cutlery. All designs are hand painted by the artisan – each individual line and color represents the interplay of warmth and coolness, blending innovation with a classic feel to deliver a free style of tableware.
