I loved the series. It was a great intro to Japan travel that I think showed how accessable it is for foreigners (Gaijin). Now too bad the Olympics will be there sucking up the oxygen but if there is any place on the planet better suited in hospitality and kindness to stomach it I haven't been there.
I wish they had more fish on a stick and gone to Issen Yoshoku I think it's right up James alley
If you haven't been go and if you do plan on going... And this is kinda against my interest because hopefully I'll win not you... but JAL is having a contest to get Gaijin out of Tokyo!
