Tsukumogami
Tsukumogami are a type of yokai from Japan. These are ordinary objects that have gained souls through some means. Usually this happened because the object was very old. It was believed that after a 100 years an object would receive a soul, making it conscious and giving it the ability to transform into a being who could interact with the world. Usually these objects would continue to behave themselves and not show off these abilities if they continued to be used and cherished by their owners. It was very old objects that were thrown away or abandoned that would start turning into creatures and misbehaving. They could do anything from pulling silly and annoying pranks to being actual threats. When an old object was broken and had to be discarded a small ceremony was held by the household to appease its spirit, and old objects in working order were not thrown away if it could be avoided. Cherishing old objects was part of the concept of mottainai, the desire to not be wasteful. Anoth...
