What is "japanification"

Japanification is the process of becoming or wishing to become a member of Japanese society. It most commonly refers to expats living for an extended period of time in Japan, though it may also be used to describe persons living outside Japan who have a certain affinity to some aspect of Japanese culture. Cultural assimilation could include adoption of Japanese mannerisms, style of clothing, taste in entertainment, and sometimes aspects of Japanese language.

In expats this process often occurs because of a feeling of isolation or desire to conform, whereas outside Japan it may occur because of an especially strong interest in some kind of fan culture based in Japan, e.g. anime, manga, television dramas, music or lolita fashion.
