Fish numbers are numbers defined by the Japanese googologist Fish.[1][2] There are seven Fish numbers:

Fish introduced Fish number 1, Fish number 2, Fish number 3 and Fish number 5 on the publication "Mathematics Seminar[3]", and he introduced the definitions of S map and S(n) map and the relationship between Fast-growing hierarchy and s(n) map.

Ohguro introduced Arrow notation, Chained arrow notation and Fish number in the magazine "Contemporary Philosophy[4]", and considered that the fact that Fish numbers are not a byproduct of some other goal-achieving process, but are devised purely for the generation of large numbers, is important in the gestalt change in the treatment of large numbers.

Kondo [5] discussed whether large numbers that did not exist before creation can be said to have existed with Fish number 1 and Fish number 7.
