Okinawa is well-known for the longevity of its people. Its subtropical climate may be one reason, but a major contributing factor is most likely the southern-most prefecture's healthy foods.
A shop in Tokyo's Ginza district serves up some of this bounty, offering a clue to a long life.
Ginza Washita Shop, which features products from Okinawa, draws a large number of customers, particularly the middle-aged and elderly. Among the fare found at the store are "ukon" (turmeric), "kokuto" (brown sugar) and "moromi" vinegar (vinegar made from distilled spirits, including "shochu" or "awamori").
