I sometimes meet Filipino tutor who are very fluent in Japanese pronunciation in online English lesson.
In fact, there was a reason for their very beautiful pronunciation.
The pronunciation of Japanese and Tagalog are very close, so people sound very fluent when speaking Japanese.
Similarly, when Japanese people speak Tagalog, they sound very fluent.
