This is a museum of yin-yang and calendars in the southernmost part of Fukui Prefecture. The Tsuchimikado family, descendants of the famous yin-yang master Abe no Seimei, lived in the Nata-sho area during the Warring States period.
The Hina Matsuri (Girls' Festival) appears in the Tale of Genji, which is considered to be the oldest Japanese tale. It is believed that people over the age of ten do not play with dolls. It used to be written in the Tale of Genji that it was something girls up to the age of ten did, and that they dressed and played with a plump doll called crawling child. It is said that the dolls were used to purify the world by transferring all kinds of abominations to them. The events that are done with Ichimatsu-ningyo (checkerboard dolls) in later times can be said to be the remnants of this custom.
The tansy rice cake has long been used in Japan and China. It is said that soaking peach blossoms in sake and drinking them on this festival day will remove illnesses and enrich the complexion. However, the peach blossoms used should be single-petalled. If 1,000-petalled ones are used, nosebleeds will occur, and white peaches are said to be abhorrent as they cause belching. from National Treasure "Dai-zousho" (1837)
