かえるの相撲 (kaeru no sumō)
This set of tops forms two frogs on a lotus leaf engaging in a sumo match. Each of the frogs can be removed from the lotus leaf base to become individual tops. This playful theme is a popular one, which is even believed to have been represented in the famous 12-13th century Chōjū jinbutsu giga handscroll (seen below), which is thought to have one section that depicts anthropomorphic frogs and rabbits challenging each other to sumo.
Hiroi Michiaki: And… This is.. Ah. A frog. Frog sumo.
Mrs. Hiroi: A frog sumo match.
HM: The frog’s on a lotus leaf…
MH: They’re lined up [on the shelves] in the shop.
HM: On top of a leaf the frogs have a sumo match. Mm. They’re tops. …There’s not really much to say. (laughs)
