Technology in Naruto

In the anime, there's walkie talkies and video games. Though, I thought it was supposed to take place in somewhat a fictional Japanese kinda world.

Any word if there's a time period Naruto is supposed to take place in, or no?

Well I do know that if guns were introduced the ninja will become absolute.Imagine this.
Ninja:around 6 years needed training
Gunmen:2 weeks is enough to kill atleast 2 ninja per person
