Ivy in the wheel stationery

Tsuta (ivy) was loved by the Edo period from the shogun to the woman in the world of the willow. The eighth Shogun Yoshimune, concerned about the extinction of his family line as the Shogun family, established Mitsukyo of Hitotsubashi, Tayasu and Shimizu, and used tsutamon as a replacement for aoi on the Tokugawa family crest. It is said that the reason why Kimigayo was so popular was that he hoped to prosper his descendants in accordance with the vitality of ivy (written by Kiji NIWA, "The more he knows about the family crest")/Geiko and prostitutes used this not only because its shape was elegant, but also because the plant became so popular in relation to other things, which was attached to a familiar customer, and also because it had a good meaning to celebrate the fact that he would not leave ("Nihon Monshogaku")
