Another thing that's interesting about Naruto's world is that there's technology, like ways to view videos, communicate over long distances – it's definitely not something that exists in traditional samurai-era Japan, but it's not a typical 'modern' Japan either. What definitely does NOT exist in Naruto's world?

It would actually take too long to really go nitty-gritty into details, but for example: one of the things I focused on was that anything that's NOT possible to recreate, or to do, using ninjustu, ninja skills, I would not develop for Naruto's world. So no cars. Because they have shuriken, the throwing stars, there's no guns either. So there were certain things I had clearly in my head that I didn't want to have available in their worldview.
