Quite a few foreign tourists who like and have visited Japan repeatedly like Kansai.
Especially people for Osaka must be more compatible with frank and downtown atmosphere of Osaka than high-class and sophisticated Tokyo.
That type of foreign men must like escorts, too.
Many escort girls in Tokyo speak other languages fluently. So you can often communicate with words.
Surely, some escort girls in Osaka are bilinguals. But more girls try to communicate without words.
It is another good point.
When you take clothes and become naturally naked, words are not needed.
You can surrender yourself into escort service skills and just enjoy sexual service.
It is sure you are so satisfied and forget the language barrier after a deep erotic time.
