> where western people write very comprehensive documents with too much information, that Japanese counterpart often won't bother reading.

Yeah, I've run into that problem in the past. I have to make a conscious effort to simplify anything I write (or say) in English in order to ensure that Japanese people understand it. They usually won't tell me if they don't understand something, whereas I'm the opposite when it comes to Japanese, so that I can optimize my language learning.
