Knowing a second language, any other language, CAN help you to learn a third language. In that way, Esperanto can help you to learn Japanese. But you won't get quite the same boost out of learning Japanese as you would, say, French or Spanish.
If you already know the basics of another language, Esperanto probably isn't going to help you as much.
