I didn't mean to say anything about a 2 language conversation. Things don't work that way, unless a character would need an interpreter.Makes sense that'd it cost more money though. Thing is, there'd probably be ways to make it more efficient. I can't claim to know them myself, but it could be worth discovering.

So did you mean in some cases the character speaks english, and in others they speak Japanese?

And the only cost effective method I can think of is finding bi-lingual voice actors.
But that not only cuts down on your skill pool a good amount, but half of the voices in the show are going to come with accents/oddities cause it's a second language (though that might actually serve as being realistic with bi-lingual characters).
