I'd reckon that there is no Japanese server that has not mbstring 
support (mbstring has it's roots in Japan).

And for Typo3 supporting it:  it depends on what the Core needs. What 
set of string fucntions is a must, what functions are would be nice to 
have? Without these infos it is hard to determine if it is worth the 
hassle. Basic functions (lenght, substr) are fairly straightforward, 
search functions are more tricky and regular expressions *) are hopeless.

*) Depends on the expression, some will work, some not.

Eg for character classes you need a workaraound:

[aäsß] => [as]|ä|ß

"." must be written to match a multibyte sequence. But that works only 
for utf-8!

This should be done by the programmer. I'm not sure if a regexp 
"preparser" is an easy task (a simple replace won't do).
