Hototogisgai is the same kind of shellfish as the mussel.


Hototogisgai is a shellfish with small roughly three centimeter size though the mussel grows.

The color is and there is a difference of a brown Hototogisgai and
black mussel.
The boots type : though the color is a black.
The size of the size is equal to Hototogisgai.
The boots type of the same size as the mussel of Natai has not been
