Ever since he visited Tokyo's Tsukiji fish market for the first time in 2012, movie director Naotaro Endo has been intrigued by the place often called "the world's largest fish market."

"I was amazed by the spectacular taste of the fish that was recommended by an intermediate wholesaler, and that experience made me interested in Japan's fish-eating culture as I became a frequent visitor," Endo says.

Endo has turned his passion for the market into "Tsukiji Wonderland," a documentary film that he has made with foreign audiences in mind.
