I believe this box is Meiji period Japanese, as I have found a few other pieces--cabinets mostly--with very very similar marquetry patterning, called Yosegi in Japan, combined with black lacquered interiors as is the case here. What I really love about it is the way the triangular motif plays out across the top and sides, in different varieties of wood--subtly and surprisingly defying expectations. Really sharp looking, and a useful box too, with an interior tray that lifts out--useful for jewelry, or all sorts of things.
Early 20th century I believe. 5 1/2 wide x 3 1/2 deep x 2 3/4" tall. Very good condition, with light wear, some light scrapes here and there, and a little cracking to the black lacquer on the underside, all as documented. I have not touched the wood.
