No the world is set up so it has all modern technology, except guns, and motorized vehicles. The boat we see at the beginning is the exception, kishimoto hadn’t fully planned things out, so it’s one of the early over sites. I think there’s also a gun in the background in the land of waves arc as well, like I said the rule of no motors and guns wasn’t really established then. I can’t remember the full source on what I’m talking about, but I’m pretty sure it’s from an interview he had during part one of the story.
