Long a popular destination for Japanese travelers looking for a relaxing beach break, Okinawa is gaining international popularity. Coral reefs provide great snorkeling and diving spots, but if you prefer to see beautiful fish without getting wet, Okinawa also has a fine aquarium. The ancient forests around the city offer a chance to view rare flora and fauna. (Editor's note: Our list was compiled before Japan's devastating earthquake of March 11, 2011. Okinawa did not sustain major damage, but we encourage all travelers to Japan to monitor travel alerts from their government.)
