File:Japan, Nara period - Storage Jar- Sueki ware - 1998.170 - Cleveland Museum of Art.jpg

This robust vessel was formed from clay coils that were beaten inside and out with wooden paddles to compress the body walls and merge the coils. In addition, the exterior surface was paddled and scored with carved wooden tools to decorate the body walls. Finally, the vessel was turned on a potter's wheel to attach the neck with a smoothly finished surface. A high firing (approximately 1000°), which culminated with a reduced oxygen phase, produced the dark gray surface tone.

Sueki ware ceramics originated in the mid-5th century, when Korean potters and kiln builders established clusters of kilns in the modern Osaka area. Other production centers were established in the outlying provinces by the late 500s, providing for the diffusion of this ceramic ware throughout the country into the 11th century. Sueki wares demonstrate ancient Japan's close cultural ties with the Korean peninsula. Similar vessels have been recovered from sites in the southern regions of the Korean peninsula.
