Walking back to the station after seeing the Studio Ghibli Museum*, we went along the canal where there was a bit of local wildlife including, one golden koi swimming among dark koi and a tortoise sunning itself.

*A must see for anyone who is a fan of their movies - fantastic! You do need to buy your ticket months before you go there. Selected travel agents outside of Japan sell them. While the shuttle bus from the station isn't a cat bus it was very cute and the bus stop itself was kinda funky as well :)
