Similar! Imari ware in Japan and DANSK fish plate in Denmark
I visited toguri-museum of art in Tokyo. It's a porcelain museum in Tokyo.
At that Imari ware(Made Mid the 17th century in Japan) exhibition at toguri-museum, I found cute postcard-Fish shaped dish imari ware.
The postcard old Imari ware is very similar to DANSK fish plate made in Denmark in my house!
In Japan, porcelain began to produce in the Arita region of Saga Prefecture in the 1610s. It was shipped throughout Japan and abroad from the port of Imari. It was known as Imari ware around the world. The main decorative techniques used during this period were underglaze cobalt blue and white, celadon glaze, iron glaze, and lapis lazuli blue glaze.
