Goya ( Bitter Gourd)
It seems Goya is cultivated in South Western Japan. Yet, my impression is that Goya is Okinawan food since they often use this vegetable in their cooking. It is bit bitter, but considered very good especially in Summer time because it has lots of vitamin C which stays in the veggie even after cooked. Also, it tends to cool off your body. This is the veggie which should be eaten in Summer. I've heard that Okinawan grandmas say to children or young girls that they 'd better not to eat this during Winter time.
