Can't find a reference for the Beads, don't know the name of what I'm looking for but beads are common amongst all monks be it for remembering prayers or mantras. The shoes however are called Geta and they are very specifically a Japanese affectation.

Japan doesn't have a school of ass kicking monks as far as I'm aware. Udyr didn't go to Monk school he's a wild man of the forest a Shaman which is the traditional priest of old Japan. Shinto is an animistic belief which revolves around living in harmony with the spirits and that is Udyr's back story.
