Approximately 36 x 36 x 3 cm This is a standard 1 shaku 2 sun (36 cm) square tray, the size typically used for kaiseki meals, capable of holding an entire meal. I believe these are from the pre-war era. These three trays appear to be in almost unused condition. Perhaps they were used by the local community in the past, as there is a single hiragana character written on the back, but it's just one character, so it shouldn't be a concern and you can use them without worry. In the past, in the Showa era, this style of tray was used in Japanese inns, but many were made of plastic for commercial use. However, these are made of natural wood, with the wood grain visible, and some areas even appear to show the texture of cloth. I can't specify the region of origin, but it's possible they are Wajima-nuri (lacquerware) with an Akebono (dawn) finish. I've arranged some dishes as a reference. You can put a lot on them. It might be fun to play at being a Japanese inn or a restaurant. Why not use them for hospitality or in your daily life? Wajima-nuri, Kishu-nuri, Echizen-nuri, Yamanaka-nuri, Aizu-nuri, I am also listing other lacquerware items. I would be grateful if you would take a look. Please consider them for your New Year's preparations.
