TIL: Western is a race
Slightly more seriously: Japanese players are a great deal more circumspect, which can pass for tactful in a bad light. When I was studying Japanese, our teacher asked us how that Japanese say "No" we answered "Iye" and she told us that was wrong. Japanese people say "Maybe" or "Yes", but extend the sound as if the sentence were to continue when they mean "No" to avoid the confrontation and disappointment outright refusal creates.
eg.
EN: "That was a great party, I think we almost made it to twisters by the 40th attempt! Let's party again next time we're both on, OK?!"
JP: "Maybe, sure...."
or
EN: "Yoshi-P, when will we have more housing wards/plots"
Y: "We are looking into doing this, please look forward to it..."
I bet you're a blast at parties.
