Not a genius, a bit of a cheat more like.

Once it was more or less established that the airport was in Japan, I took a leisurely google maps tour around the coast until I recognised the river mouth and harbour, then googled the Kochi food speciality.

I used to only guess places I’d actually visited, but I do like this game so I have relaxed my principles. I have been to Fukuoka and Nagasaki though, so near enough (as the crow flies )
