Shooting is underway on a major documentary film about one of the world's largest fish markets, Tsukiji in central Tokyo, before the facility closes and reopens at a new location.

At 80 years old, the ramshackle but buzzing complex is earmarked for demolition after trading moves to a site in the adjacent Toyosu neighborhood in 2016.

The filmmakers aim to preserve on screen what they see as the epitome of Japanese food culture. Kazuha Okuda, a producer, said this first ever documentary about the market will not only record it as it was, but will help future generations worldwide see how those in the seafood industry go about their business.
