A tea bowl originating in the early Edo period at a Tateno-type kiln. It is associated with the style known as Hibakari-de, vessels said to have been made by Korean potters who migrated from the northern Korean peninsula and brought clay to Satsuma—hence the tradition that “only the fire was from Japan.” Such pieces were fired first at the Uto kiln, classified under Kochosa wares, and subsequently at the latter, the Osato kiln; the present example is likely from the latter. It formed in the gently flaring Komogai shape, the bowl rises softly from a well-cut foot, with the rim subtly turning outward. A fine network of crazing covers the entire surface, while the interior features a small, neatly kagami-ochi dent. The surface has matured through long use to a warm loquat hue, lending the piece a deep and mellow character.

The bowl is in very good condition, with no notable flaws. It is housed in an old box inscribed with the name “Kumagawa” in gold.
