Since its birth in 1947, the Constitution has always been a target for revision, primarily because it was drafted by Americans rather than Japanese.

Even the Liberal Democratic Party has sought the establishment of "Japan's own Constitution" as a main goal since the party's founding in 1955.

Although the Constitution is now 56 -- the age of its Meiji predecessor when it finally met its end -- and remains intact, the pressure for revision seems to be growing stronger.
