"Kishimoto created Konohagakure without specifying a specific era or location in the real world, noting that the village is "just a place in [his] head". Without a specific time period, Kishimoto included modern elements in the series such as convenience stores, but specifically excluded projectile weapons and vehicles from the storyline. For reference materials, Kishimoto performs his own research into Japanese culture and alludes to it in his work. In an interview, he commented that he "often visits Japanese gardens and [goes] to Kabuki performances" for reference material.
Kishimoto added that, as Naruto takes place in a "Japanese fantasy world," the creator has to "set certain rules, in a systematic way" so that he could easily "convey the story". Kishimoto wanted to "draw on" the Chinese zodiac tradition, which had a long-standing presence in Japan; the zodiac hand signs originate from this. Regarding technology Kishimoto said that Naruto would not have any firearms. He said he may include automobiles, aircraft, and "low-processing" computers; Kishimoto specified the computers would "maybe" be eight-bit and that they would "definitely not" be sixteen-bit."
