How similar is the Japanese spoken in Taiwan to the Japanese spoken in Japan?


I've [heard](http://en.wikipedia.org/wiki/Languages_of_Taiwan#Japanese) that
Japanese is spoken by some Taiwanese people who were old enough to have lived
during Japanese rule, along with some people who've learnt it for other
reasons. For younger people, I've been told Mandarin or English would be the
best means of communication, but I have a tendency to socialize a lot with
retirees.

How similar is the Japanese spoken in Taiwan by native speakers to the
Japanese used in Japan? Did the two diverge after 1945? Are words that entered
Japanese after 1945 also used in the Japanese spoken in Taiwan?




As far as I know, there is no difference, because Japanese is mainly used as a
language to talk to people in Japan which is right close by, and to enjoy
media and products from Japan. Japanese is still widely studied in Korea for
the same reasons. [Japanese textbooks in
Taiwan](http://www.nkg.or.jp/kenkyu/kenkyushukai/2011/kk-11-04yoshi.pdf) seem
to demonstrate an eagerness for fluency and avoiding confusion in business
conversation.

Taiwan was under Japanese administration until 1945 and the language has not
changed significantly since then.

On the other hand, the Japanese used in Hawaii and Brazil, among the lower-
class immigrant Japanese communities there, may preserve some older forms.
That immigration happened around 1900.
