(Where's Yamada and the Kitaro Goods)
Oboroguruma: A demon-infused ox-cart that runs over people. The story dates back to the 1300's from the Ginza area in Tokyo.
Guwagoze: There's nothing on Guwagoze in English. The Japanese wiki page lumps him in with several other demons associated with Gangoji Temple, one of the oldest Buddhist temples in Nara dating back to before the 700's. The Original Art page also associates Guwagoze with Gangoji.
Daruma: Daruma is generally an oval-shaped figure with a red body but no arms or legs, modeled after Bodhidharma, the founder of Zen Buddhism. Daruma figurines can be purchased at various shrines and stores, but without pupils in the eyes. The tradition is to paint in one pupil when you start a new task or project, and the other when you finish. In the Gegege no Kitaro world, Daruma are malevolent creatures that actively attack humans. They are partial to locations that have "4" in the name, such as the 4th floor of office buildings.
Kasa Jizo: Jizo are Buddhist statues that can either represent a particular bodhisattva, or just be a marker along the side of a road. Often, jizo are dedicated to children lost during birth. "Kasa" is a conical straw hat. One particular folktale involves a Jizo statue that is given a straw hat, and then rewards the samaritan as thanks afterward. It is common to see jizo statues wearing red shawls and straw hats during the winter.
Zashikiwarashi: These are spirits that occupy homes and bring good luck. They are childlike, and prone to playing small pranks on people. They may have originated in Iwate Prefecture.
Ushirogami: Nothing on this one in English. The Original Art and New Yokai pages indicate that it lives in a demon cactus, and that it originated from stories from China. The pictures I've seen of it show a female figure with a black face, eyes but no nose or mouth. Sometimes the entire body is black, sometimes only the head. The name translates to "Back or behind" and "god". One possible interpretion would be "the god in the back" or, "the god behind you".
Note that there is only one volume left to this DVD magazine series.
