Kyushu, being the most southerly of the main islands of Japan has the mildest climate. This is where the Japanese sweet potato, satsuma-imo, grows to perfection.
At a view point overlooking Lake Miike we came across this guy.
I like to ask permission before taking photos of people in the street. Not only was he happy to oblige, the sweet potato man gave me some to try. As a kid I really liked to eat chestnuts roasted on the coals of an open fire. The satsuma-imo brought those memories flooding back. The texture is similar and the taste is delicious. My face must have lit up.
Good karma. Within minutes he had sold a bagful to our little band of tourists.
