Mamukai Turtle Lumbar Cushion

[Mummy] There are several kinds of turtles. Turtles and tortoises live in Ikenuma and Umigame live in the sea. The emblem was Mizugame. There is a pattern of a water turtle with a straw raincoat and a straw raincoat. In the crest, it is called 'Minokame.' In my opinion, Minokame is not a special tortoise like this, and it is made of seaweed-like water grass on the shell, not from the tortoise shell. According to "Kokon Chomon ju" (A Collection of Tales Heard, Past and Present), around 1145-51, a tortoise with a hair of one shaku long was presented to Chisoku-in Temple by a person in the western province, and was mentioned as an auspicious tortoise.
