Japanese to English is pretty tricky, in part because it’s more standard in Japanese to fully omit words instead of using a pronoun when something is known from context. A response to “What are you doing with that book?” in English might be “I’m going to return it,” but in Japanese you’d just say “Return” (返す。). So a machine translator would probably have to be very good at context to guess right a lot of the time.

We can fix it.
