snake and two human arms attached to it, and a tsunodarai (four-handled basin) with a face and growing teeth, among others. Also, a face that appears to be what the tsunodarai is based on appears in the Yūzū Nenbutsu Engi Emaki (融通念仏縁起絵巻) and the Fudō Rieki Engi Emaki () where a yakugami with almost the same appearance appears. However, all of these were not merely tools, but ones that are a hybrid with a tool or oni. This characteristic can also be seen in the Tsukumogami Emaki and the Hyakki Yagyō Emaki. The Hyakki Yagyō Emaki (百鬼夜行絵巻) from the Muromachi period also depicts many of what appear to be yōkai of tools. In the present day, these tools yōkai are thought to be depictions of tsukumogami, and it has been inferred that the parade depicted in the Hyakki Yagyō Emaki is likely the "youbutsu" (aged objects) of the Tsukumogami Emaki in a festival parade. Works about tools In works about tools having a human personality, tools such as the "chōdo uta-awase" that would perform uta-awase can be found before the Muromachi period, and it is thought that these are close in concept to being the idea of "things that tools turn into" as depicted in the Tsukumogami Emaki. Understood by many Western scholars, tsukumogami was a concept popular in Japanese folklore as far back as the tenth century, used in the spread of Shingon Buddhism. In Japanese folklore According to Elison and Smith (1987), Tsukumogami was the name of an animated tea caddy that Matsunaga Hisahide used to bargain for peace with Oda Nobunaga. Like many concepts in Japanese folklore, there are several layers of definition used when discussing Tsukumogami. For example, by the tenth century, the Tsukumogami myths were used in helping to spread the "doctrines of Shingon Esoteric Buddhism to a variety of audiences, ranging from the educated to the relatively unsophisticated, by capitalizing upon pre-existing spiritual beliefs in Tsukumogami." These "pre-existing spiritual beliefs" were, as Reider explains: Tsukumogami are animate household objects. An otogizōshi ("companion tale") titled Tsukumogami ki ("Record of tool kami"; Muromachi period) explains that after a service life of nearly one hundred years, utsuwamono or kibutsu (containers, tools, and instruments) receive souls. While many references are made to this work as a major source for the definition of tsukumogami, insufficient attention has been paid to the actual text of Tsukumogami ki. By the twentieth
