During the Muromachi period, Murata Shuko (1423-1502 CE) introduced a new concept called "wabi-cha" to the Japanese tea scene. Shuko diverged from the prevailing trend of luxurious Tang dynasty utensils such as Kinuta Seiji and Keshiki Tenmoku tea bowls, opting instead for mass-produced commoner wares known as Shuko Seiji and flawed Tenmoku ceramics called Shuko Tenmoku.
This particular item is a typical Shuko Seiji tea bowl. Characteristic of Shuko Seiji, it has a dark green or yellow-brown color with comb-like patterns called "nekoge" on the interior. These bowls were fired in kilns around Fujian Province during the Song and Yuan dynasties.
It is in good condition and would make an excellent tea utensil to cherish. It comes with a wooden box and cloth covering.
