I have followed above instructions, but I still cannot get Japanese contact
index to show up. I have installed East Asian languages (in "Regional and
Language option) which includes Japanese. I also added Japanese support on
"Office Language setting".

Although I don't see any Japanese contact index, I see other languages such
as Thai and Greek which I have not installed nor enabled.

I really need to use Japanese contact index, since my contact entries are
growing rapidly.
