The Ariake Sea borders lies in the northwest of Kyushu, bordering on 4 prefectures: Nagasaki, Saga, Fukuoka, and Kumamoto. Its huge tidal range, as much as 6 meters, is the largest in Japan. Low tide reveals massive mudflats stretching out some 7 kilometers from the shore. This ecosystem is home to some very unusual creatures, and since the old days it has provided a rich bounty of seafood for the local people. On this episode of Journeys in Japan, we explore this unique environment, its history and culture.
