A sake flask (tokkuri) of Tamba ware, fired in Tamba-Sasayama during the early Edo period. The vessel forms a generously proportioned body with a sharply angled waist, its surface covered in akadobe—a red clay slip—fired to a deep vermilion tone.

Across the side appears a striking patch of namako-yōhen (sea-cucumber kiln effect), created when silica contained in the pine firewood melted and vitrified during firing. Though accidental in origin, this transformation becomes an essential visual accent, lending tension and vitality to the overall composition. It is a work that embodies the unadorned strength often found in vessels made for use.

A chip is present at the mouth, and minor flaking can be seen within the area of the namako-yōhen. Aside from kiln-related imperfections, there are no conspicuous flaws, and the condition is generally good. Accompanied by a fitted wooden storage box.
