23197 人間国宝 13代今泉今右衛門 (Ironabeshima Ink Dew grass Forehead plate)
Height 8.0 cm
Diameter 41.0 cm
It is a work of Imaemon Imaizumi, the 13th National Living Treasure.
After the name of the 13th generation, what I noticed was the early Imari's "Fukizumi" technique that sprayed blue.
The colorful dew-sentences are carefully drawn.
