Every region speaks Common. 95% of the world does. Only extremely isolated pockets don't know Common, like some of the Mamo.
Most regions have their own tongue, too, which is a cultural tongue. It's mostly used within a family or community, and never used in Pokemon battles without special training. Creshire doesn't really have a cultural tongue unless you count Mamo. Creshire has been taken over so many times that using Common is the only solution to the melting pot here.

English is not Common, and some of Creshire's ancestors did speak English as a cultural tongue.

Tandor's cultural language would be something like Portuguese, as I believe it is inspired by Brazil where JV lives. South American.

<region>ese or Japanese are both acceptable names for these cultural languages. "Japanese" is just a stand-in for whatever the Common word for such a tongue is. You know, in Japan they call it Nihongo, it looks like. In Common, it would be something else, which we understand as "Japanese."

Hopefully that makes some sense.
