Unsure if Chinese or Japanese, see the character marks to the base (refer to the 3 photos) 16.5cms high, in superb condition. No chips, cracks or repairs.
What an absolutely superb piece, but I can’t see any makers mark / name, looked everywhere. Looks to date the 1950s / 1960s era. Measures 69.5mm in diameter. Apart from the marks to the pad, its in great condition.
