Well, I've never been, but I plan to. I guess I'm an otaku of sorts, but honestly, that's not what drives me to go.
I am genuinely interested in those islands. The history, the food, the culture, everything. The fact that they've survived history as a few islands off the coast of a giant mainland, and stayed Japan, not just a territory of Korea or China, very much interests me.
The fact that, once I get there, there will be anime/manga/video games/etc., probably won't even interest me nearly as much as everything else.
And I do definitely intend to go, at least once in my life.
Just no time soon,
. Money, school, you name it, it's an obstacle right now, lol.
