Details
There are several ways to romanize Japanese.
Using this implementation, you can convert hiragana and katakana as 5 different styles;
the wikipedia style, the traditional hepburn style, the modified hepburn style,
the kunrei style, and the nihon style.
Note that all of these styles return a slightly different form of
stringi::stri_trans_general(text, "Any-latn").
