What era is the technological background of Naruto probably in?

You know, Japanese anime very well escaped the restrictions of the state is often completely an original world, so you can not use our social and technological development standards to look at him, like the lamp, which is a must-have, the telephone, no, why? Should be for the phone is good communication, some things in order to a lot of plot needs can not be spread at once, the need for oral, or carrier pigeons (eagles). And then like air conditioning, washing machines, such as still appeared, these do not account for too much role, the TV does not have, is also a limitation of the rapid dissemination of information, and computers, this is in fact there, because in the medical reality of the time there is a record of data, but that's all, there is no Internet, this is still a limitation of information, there is no game, that must be, it will affect the plot.

Transportation, don't you think ninjas running and jumping all over the branches of trees is cool? And cars, trains, and even airplanes, aren't those pretty restrictive to ninjutsu practice? At most, horses appeared in Yukihime no Ninjutsu, and carriages appeared in the plot, so the notion of cars at all is a rationalization for the world as a whole.

Weapons, you can notice that there are no firearms in Naruto, it's all bladed weapons, even the samurai have long swords, that has to be, isn't that what manga fans want to see, intense physical confrontations, exciting ninjutsu duels? If you take guns, cannons and even missiles, is it still a ninja chapter? It's like modern warfare.

There are also some things are quite amusing, like the projector and so on, the old camera have appeared, proving that in general the world of "Naruto" is still technological water backward, but then there are some more strange existence, such as our society in recent times only appeared in the washing machine, air conditioning, but the general thing is still relatively backward, and also belongs to the era of the Cold Weapons.
