Hi, the shape and technique of this piece look Chinese to me! I have no idea how old it is, but I think certainly not older than C 20th. The "plum blossom" appears also in Chinese art, not only in Japan. This kind of furniture is still being produced... The mother-of-pearl-inscription is certainly the maker's signature, as the last sign means "has made it". As to the name of the producer I cannot help you unfortunately...
