This is an unmarked Japanese Satsuma box dating to the Meiji Period, and most likely the 19th century, pre-1900.
The box is heavy and weighs 1.5 pounds. It is 2 3/4" high and 3 7/8" wide.
The box is square and rests on four solid feet. The ground is a dark mahogany color, not the chocolate color of ordinary post-1900 Satsuma. The feet and bottom edge are black. On each side of the bottom there is an enameled orange flower set against blue, which is set against black. The lid has a black circle over which are more enameled flowers with green and blue leaves.
The interior of the lid and bottom are glazed and so is the bottom of the box; the glazing is crazed. The rims are not glazed, but colored in the mahogany. An unglazed rim is usually an indicator that the age is pre-1900.
There are nicks along the corners and edges of the top and bottom; almost every corner has a nick and almost every side has one or more small nicks. The rims show loss of color due to rubbing wear.
The prior owner put pads on the bottom of each foot and the pads show a lot of age.
The piece is unmarked; however the bottom has a darker smudge that might have been a maker's mark at one time.
