Yes. They would be very amazed at Japanese young people, and or watching Japanese TV, seeing the son of the Emperor they fought for on TV, but then hear Japanese TV commentators talk about him and the Imperial Family in very casual ways, in much less honorific speech in Japanese than reserved for "living gods", and thus, in their own minds, affording the Emperor no respect.
They might not take it well, and then commit suicide, or just wish to die as a result. I think they ought to stay in the PI if they are capable...and be left alone--but the Japanese Nation will probably not allow it.
