End Table ??  

From the Web
we learn this:
"From the end of World War II, the allied forces occupied Japan for seven years. The unofficial occupation started Aug. 14, 1945, and the occupation lasted until April 25, 1952. During these seven years, half of all Japanese exports had to be labelled as coming from "Occupied Japan."
Pieces from Occupied Japan are marked with an "OJ". This mark will be under the glaze. Since only half of the pieces required the identity mark, it is possible to get two-piece sets, such as a cup and saucer, where only one item bears the mark."

Legs
What do the legs look like?

Looking at all
the Aalto stools online, I'd say yours has legs that are thinner and with a broader sweep to the bend. An unauthorized copy from the early days -- or an improperly-overseen licensee ?
Still a very nice object !
