[5]By the end of the Kamakura period (1185–1333), as the custom of tea drinking spread throughout Japan and the Tenmoku chawan became desired by all ranks of society, the Japanese began to make their own copies in Seto (in present-day Aichi Prefecture).
[6] With the rise of the wabi tea ceremony in the late Muromachi period (1336–1573), the Ido chawan, which originated from a Met-Saabal or a large bowl used for rice in Korea, also became highly prized in Japan.
"[9] Another chawan type that became slightly popular during the Edo period from abroad was the Annan ware from Vietnam (Annam), which were originally used there as rice bowls.
Normally the bowl would be wrapped in an orange turmeric-coloured cloth called ukon-nuno (ウコン布) for storage in the box, which apparently helps ward insects away.
A cloth bag shifuku (仕服) made out of silk or brocade can be used for storage of special tea bowls, especially for tenmoku chawan types.
This is supported by four smaller cushions on each side inside the wooden box to help stabilise and protect the bowl.
