Businesses operating at Japan's largest fish market are increasingly trying to boost exports, sensing demand overseas for such fare as octopus, abalone and stonefish sold with the renowned Tsukiji brand.

Seafood consumption in Japan has been declining in recent years as people shift to meat, which is generally cheaper and seen as easier to prepare.

But the traders also believe the market's planned move in fiscal 2016 from its historic but poky site in Tokyo's Chuo Ward, to Toyosu in Koto Ward is a good time for them to make full use of more modern premises and expand their business reach.
