The Japanese kicked ass economically and reached a peak in the late 80s and early 90s. At this point, they had topped out, reached a sort of utopia where anyone who wanted a job could get a job. Then the people stop having babies and played Nintendo or watched anime porn to escape their "matrix-ish" first world problems. The problem is that the Japanese people were never meant to be pacifist pussies, constrained by their constitution and the embarrassment of their past aggression. Don't worry. They will be back. This time in a more constructive way. Mainly because crazy Kim will ensure that Japan develops nukes, Gundam suits, Jaegers, etc.
