Even likely, given the number of US military stationed there. Curious if Korea also gets a boost on military bases (and Japan).
Lots of Filipino* and Korean wives. Not so many Japanese. The theory is Japan is nice and there is less to "escape" from. Not that many German, Italian or English wives either even though we have a lot of military there. Hell, I've known more wives from Panama (2) than I have from Japan, Italy and England combined (1).
All anecdotal of course.
*Less now than 15 years ago of course since we've been gone from there since the early 90s
