Nanako-nuri

A tsugaru-nuri technique which involves creating a textured surface by sprinkling the wet lacquer surface with rapeseeds or hemp seeds to create a pattern of small craters. (mustard seeds seem to work well too) The surface is then lacquered over with a contrasting color and polished smooth to reveal a pattern of circles reminiscent of fish roe.

Literaly: fish roe painting.
