Pretty Princess traveled all of the way from Manehattan to Japony to spend a couple of weeks there. It just so happens that Japanponycon was happening around this same time! Inspired by one of the advertisements, she wore a kimono to the event.
(Artist's note: This actually WAS inspired by a Japanponycon flyer :) )

I wonder if the local ponies call it Nippony, while we outsiders call it Japony
