Yes, terrorists. That according to Yukata Kubota, the current head of the Copyright Association for Computer Software in Japan in an interview he did with Famitsu:

The fact is that you can download any Nintendo DS game as much as you want, so there’s no way to even calculate the damage. This is an issue that affects our national interests, and personally, I see it as a form of information terrorism that is crushing Japan’s industry.
. . .
it is not explicitly against the law” in Japan presently for individuals to buy a flash-ROM cart and download commercial DS software for it. However, a revised copyright bill currently working its way through legislation in Japan would make it an express offense to download unauthorized, copyrighted audiovisual content, as opposed to offering it for sale.

Again, I’d like to state for the record that DS Ninja does not advocate piracy, but instead we encourage you to practice ‘Ninjacy.’ Essentially that means doing whatever the hell you want under a cloak of perfect stealth. You cannot be labeled a terrorists because your existence is known by no one.

That’s the difference between Ninjas and Pirates.
