Tosa Obake Zōshi

The Tosa Obake Zōshi (土佐お化け草紙) is a Japanese yōkai emaki (illustrated scroll). It was written by an unknown author and is set in Tosa Province (now Kōchi Prefecture), with 16 sections about yōkai in total; it was created during the Edo period. There are two editions, the private collection, originally owned by the Horimi family, and the collection of the Sakawa Education Committee of Sakawa, Kōchi Prefecture.

Summary
At the opening of all sixteen yōkai tales, yōkai from each area of Japan gather at Tosa, and in the end, at dawn, the yōkai disperse, bringing each tale to its conclusion.

It is notable for collecting folktales from Tosa during the Edo period, including the Kechibi and the Yamajijii among others. The yōkai are presented with a rich local colouring, but it is a work that has attracted national interest as recounting iconic yōkai tales of the Edo period. The depictions present the yōkai as mischievously naive and playful, allowing the reader to feel close to the yōkai rather than as dreadful creatures.

Horimi (private collection)
It is estimated the private collection was composed during the period spanning from the middle to late Edo period. According to the postscript written when the end leaves were repaired after the war, the head karō of Tosa, the comber of the Fukao family, received this work from Masanari Eisuke, the 3rd from the Yoshimoto family, who worked for them for years since in Kan'en 2 (1749), and the sixth daughter of the Takehira family brought it into the family she married into, and from Heisei onwards, it has been passed down in that family. According to the postscript, it was used by a young lord for staying over the night, and the author is seen not as a famous artist of yōkai and yūrei and so on, but rather a nameless artist who lived in the countryside.

The Horimi family copy is held at the Kōchi Prefectural Museum of History.

Sawaka Education Committee
The works of the Sawaka Education Committee collection were made in Ansei 6 (1859), according to the statements in the end of the book. This is during approximately the same time period as the private collection and the yōkai tales stated earlier, and thus it is believed this emaki either was drawn in succession at that place, or was drawn as a copy of the private collection. However, because the sequence of tales and the characteristics of the yōkai are different than the private collection, it is not simply a reproduction; the chronology of the owners of the Sawaka Education Committee collection is also unclear, so how the book was drawn and passed down still awaits further research.
