Suppose you are in the United States and your last name is Tanaka. You interview an accountant and ask for a proposal for bookkeeping and accounting for your software company. Suppose the accountant comes back with a proposal which quotes you including a line item for Japanese translation. (This is quite unlikely, but roll with it.)

You tell the accountant "Uh, thanks, but: we'll be working together in English." "Oh yes, that's good, we don't really speak Japanese." "Why are you quoting for Japanese translation then?" "To cover our increase costs of dealing with you." "So you... expected to hire an external translator?" "Well, no, more of an aggravational cost sort of issue rather than a direct cost sort of issue."

This would be cause for an absolutely nuclear reaction from the client in the US. In Japan, it's Tuesday.

Fortunately not my Tuesdays in Japan. I've been here seven years and never seen behavior like that. Sorry you've had such bad experiences.

Yes. You can get some things done in Tokyo using only English. You can get nothing done in NYC using only Japanese.
