Japanese is an East Asian language spoken by about 126 million people, primarily in Japan, where it is the official language and national language.
The influx of Japanese loanwords can be classified into two periods, Japanese colonial administration period (1942–1945) and globalisation of Japanese popular culture (1980-now).
As Indonesian is written using Latin script, Japanese romanisation systems influence the spelling in Indonesian.
Most vowels are retained without significant change in Indonesian, except in vowels length and pitch accent (there are no vowels length distinction and no pitch accent in Indonesian).
