Both hiragana and katakana work. But in my experience, Katakana is way 
more frequent. Please make sure to accept both half-width and full-width 
Katakana; getting a message like "only full-with Katakana accepted" is 
very annoying when this can be done automatically. Same for 
Hiragana->Katakana conversion.

This at first sight sounds like a neat idea for Japanese. However, I 
have never seen it (and living in Japan, I would have had ample occasion 
to see it). There is always a "pronunciation" (reading/yomi) field, but 
it's never pre-filled. My guess is that the reason for this is that 
there are just too many variations in Japanese names. For Chinese, 
there's usually just one reading, and occasionally (as discussed in this 
thread) two or more, but for Japanese, the percentages are different.

Regards,    Martin.
