a water wheel travel mug

[Mizunisuisha] It is also referred to as Suisha-mon or Hishakuguruma-mon. It is a crest representing a water wheel. There are two types of water wheels: one with a board on a spoke and the other with a ladle on the circumference of the wheel. This is called a hishaku-guruma (a ladle with a ladle) by calling it to the place where the hishaku is attached. It is said that the crest was this Hishaku-guruma . In later years, however, since this ladle resembles the shape of a mallet, it is called a mallet by mistake, and it is intentionally made by imitating the shape of a mallet, so that the name is applied to the family crest of the world. However, the fact that it is not a mallet is seen in the old days of this monsho, not only does there exist those that depict the stitches of the ladle, but also there is a description in the section of the crest of the Doi clan in "Kansei Choshu Shokafu" that it is clearly indicated that it is the eight-ladle with a water wheel. The eight-ladle means a water wheel composed of eight ladles. (Source: Yorisuke NUMATA, "Nihon Monshogaku") / This design adds my interpretation to the drawing of "Mizuni Waterwheel" in the same book.
