Japan has always been independent.
It never gained independence as it was not a democratic. It never gained independence from anyone because it was never under the control of any other country. Actually it did gain independence again in 1952 from US occupation after World War II. The state does not need to be democratic to be independent, and Japan operates under a parliamentary government with a constitutional monarchy. Ending an occupation does not imply gaining independence. It simply means an occupying power leaving the country and restoring/handing back administration of the affairs of a country to its nationals. Otherwise, Uganda would have another independence after Tanzanian troops pulled out after liberating it in 1979 (in addition to the one in 1962).
