Like Javizy san said, everyone regardless of where one's from has different likes and dislikes about everything. Also understand what sodapple san's asking.
Most likely not many Japanese wants to go where there is no signs in English/Japanese....many tours are made for Japanese to go to Europe, US, Australia, and Korea. A lot of females love going to France for some reason.....and actually quite few people study French for that purpose.
Now that gas price is skyrocketing, many people just stay in Japan.
Personally I prefer the places where not many people go....at least not touristy place.
