In Japan, there is a long tradition of using trained cormorants to catch river fish. It's always done at night, using braziers. Fishing with cormorants -"ukai" in Japanese - is still practiced in 13 places around the country. It's very popular with visitors. Every year, more than 150,000 people come to see this traditional practice. And part of the fun is watching the spectacle from on board special viewing boats. On this edition of Journeys in Japan, John Gathright discovers the traditions of cormorant night fishing, and he meets the master fishermen who continue this ancient practice.
