Tsukumogami are an entire class of yōkai and obake (monstrous spirits) in Japanese mythology. They are made up of ordinary household items that have come to life on the one-hundredth anniversary of their birthday. This virtually unlimited classification includes:
- Bakezōri (straw sandals)
- Biwa-bokuboku (a lute)
- Burabura (a paper lantern)
- Karakasa (old umbrellas)
- Kameosa (old sake jars)
- Morinji-no-kama (tea kettles)
- Mokumokuren (paper screens with eyes)
