Pretty much like the title says. I wanted to gather all the material (folk tales, religions, japanese and other asian cultures etc) that were adapted and added by Kishimoto in to what became Naruto. Please feel free to list whatever you can think of.
I'll start with some things off the top of my head.
Jiraiya, Tsunade and Orochimaru in Naruto are inspired by the characters from Jiraiya Gōketsu Monogatari (Tale of Gallant Jiraiy)
Kiba and Akamaru's look was inspired by San from Princess Mononoke.
The Hyuga Clan having a Taoism inspiration. Also Gentle Fist being inspired by Baguazhang and Dim Mak, two chinese martial arts.
The Uchiha Clan being influenced by Shintoism. With Tsukiyomi, Amaterasu, Susanno, Izanagi and Izami all being deities in that religion.
The Senju Clan using Buddhist imagery. The clan symbol is a Vajra, and Hashirama's ultimate attack is a giant buddha.
I'll add more when I can think of more.
