About the Marimo Motif
While you asked for a “Fishes” stamp, the 55 Yen value in this series actually depicts Marimo, which are large, rare balls of green algae found in Lake Akan (Hokkaido, Japan). They are a designated national natural monument of Japan. The stamp is often grouped into “Nature” or “Flora/Fauna” topical collections.
However, if you meant a stamp featuring a more common fish design, Japan did issue a 10 Yen Salmon stamp later in the decade (part of the 1959 series), but the 1956 55 Yen Marimo is the most prominent single-value nature/marine-life issue for that specific year.
