Kotaku: ''The late great George Carlin once famously spoke of words that cannot be said on television. Japan, too, has its own list of words and phrases that are taboo.
As of last count, there are over 350 words and phrases deemed “problematic” if used on air. While none are legally forbidden, use of any of them is strongly frowned upon. Most television studios will self-censor, preventing the use of any of these words or phrases on the air.This self-censorship is also spread to other forms of media aside from television.
But what about media that has already been released before specific words were put on the no-no list? Publishers will either discontinue such works or, in some cases, go back to previously existing works and “update” them. ''
