泥鰌と田螺 (dojō to tanishi)
“loach and pond snail”
This top depicts a loach and pond snail. These are freshwater aquatic animals, often found in ponds. Hiroi-sensei stated that these tops are meant to be good luck charms for protection against fires, since both are water creatures.
Hiroi Michiaki: This is… a pond snail and a loach.
Mrs. Hiroi: Mm. Pond snails are in paddy fields.
HM: It was a pond snail and a loach, or I have a feeling it might have been a horned turban snail and a loach…
MH: It’s a pond snail and a loach.
HM: And, um, this is the shell of the pond snail in the paddy and then the loach. You put those together and it [becomes] a top, and this… it’s a charm for protection against fire– these creatures live in the water, so [it makes it so] fires won’t happen. [This] top is that kind of charm.
