So I bought a bunch of comic books in Japan enough to fit a specialized plastic box for comics in it (it's a big box stuffed with comic books).

I plan to stuff it in my check in baggage on my way back (Or should I carry it all in my handcarry bag?). How likely will I be asked to open it up for inspection? Some of them have rather misleading (things like art of half naked girls) cover art, despite not having any adult contents.
