Short answer, no. Long answer, also no.

You need to defend patents and trademarks, else you lose them. You don't have to protect copyright- works you create are yours, indefinitely (creator's life plus 70 years plus some company still exists plus whatever BS Disney comes up with next). Piracy certainly doesn't involve the first two, at all.

If Japan's IP laws are f'ed up, it's because it supports "holders" too much, enables patent trolls and gives corporations too much power.
