Interesting! 7-Eleven, Family Mart and Lawson are all in Thailand too, but I think 7-Eleven is overwhelmingly dominant, eg on my street in a 100m radius there were three 7-Elevens to just one FM and one Lawson.

Update: some stats, it's not even close... ~200 Lawson in Thailand, ~200 Family Mart (now Tops Daily), and 14,000 7-Elevens. Guess I just spent a lot of time in places with Lawson and Family Mart. This also means the 7-Eleven population density is about the same in Japan and Thailand, around one per 5k people.
