Gotochi cards

Anyone heard of Gotochi postcards ? They're postcards circulated by postal government of Japan, each region has their own set of cards, that can be bought in that Post Office only. They are usually landmarks, food, or something traditional. The only problem is because they're quite expensive, a lot of Japanese swappers are reluctant to send them abroad written and stamped. My favorite card I've received is from Kyoto.
