Gemini describes this as a Japanese Shiro-Satsuma Kōgō (a traditional lidded incense container used in the Japanese tea ceremony). Given the artist mark and its condition, this authentic piece is estimated to be worth between $300 and $600 USD on the international antique market. The hand-painted red signature on the underside reads "薩摩 寿官" (Satsuma Jukan). This identifies the piece as an authentic product of the highly prestigious Chin Jukan Kiln (沈壽官窯) in Kagoshima. The Chin Jukan lineage spans over 400 years and is widely celebrated for popularizing fine white Satsuma ware globally. The style of the script and overall paint texture point to mid-20th century production (likely by the renowned 14th generation Chin Jukan, or mid-late Shōwa period workshop output).
