I've tried translating some paragraphs from English to Japanese and back and it now seems intelligible enough to be useful. Previously, it produced complete gibberish. The mistake you pointed out seems rather odd. Computers are supposed to be good at arithmetic. With my limited knowledge of Chinese (that part is all Kanji) even I would get that right (under 1,030,000JPY). But that's the problem with neural or statistical translation - even with the code available, you can't easily tell why it's happened. Perhaps it got confused because １３０万円 appears later in that sentence.
