Eight-wheel turbine watch

It is also called Yatsu-suisha Pattern or Hishakuguruma Pattern. 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 a 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 mistaken for a mallet and is purposely modeled after the shape of a mallet, so that the name of the mallet is attached to the family crest. However, it is not like the hammer ... "Kansei Choshu Shokafu" (Genealogies of Vassals in Edo Bakufu), and it is also clearly written that it is a water wheel, Hakkarahaku. (Written by Yorisuke NUMATA, "Nihon Monshogaku")/This name was derived from "Maruwari Nihon no Kamon" written by Kiji NIWA.
