Vintage cream-colored tokkuri with a raku (crackle glaze) finish, handpainted with a red floral design-- Perhaps an abutilon, or parlor maple?
The kanji on the underside reads "nine valleys"-- Kutani-- which indicates this is made in Ishikawa Prefecture's Kutani kilns. Handmade Kutani is rarely exported, and in fact this specific piece was sourced from a local antiques dealer that imports directly from Japanese auctions and estate sales.
Capacity is roughly 180ml, size is 13.5cm tall, 6cm wide.
