Penguin relationship diagrams at the aquarium

Apr 24, 2026

The Kyoto Aquarium in Kyoto and the Sumida Aquarium in Tokyo each have detailed relationship diagrams for their penguins. The above is for Kyoto.

The networks are framed as reality shows with weddings, divorce, and cheating, along with likes and dislikes of each penguin. Watch out for the penguin named Pon:

Kuruma and Tako live next door to each other, and Pon has been visiting each of them in turn for snuggle sessions. Both boys are obsessed with Pon, but it seems neither of them can fully satisfy her. What’s the fate of this neighborhood love triangle!?

Oh my.

I don’t know why these exist, but it’s nice that they do. The aquariums have updated the networks each year since 2024.
