Plans to move Tokyo’s Tsukiji fish market – the world’s largest – were put on ice Wednesday over fears about toxic contamination at the new facility, as the cost of the move soars. The market is regularly the site of record-breaking bids for fresh fish and we have revisited it often over the years for that reason.

The megacity’s new governor, Yuriko Koike, said she would postpone the move set for November until at least early next year, as she awaits final groundwater testing results at the new site, a former gas plant. Anyone planning a trip or intending to bid on any bluefin tuna should take note.

Plans to uproot the more than 80-year-old market, a popular tourist attraction, have been in the works for years, with advocates citing the need for upgraded technology.

But Koike, a former TV anchorwoman elected last month as the Japanese capital’s first female governor, had pledged to reconsider the plan.

“Needless to say, it is a market that handles fresh food,” Koike told a press conference as she announced the delay. “The Tokyo metropolitan government, which chiefly runs the market, is responsible for telling the world: ‘It’s safe.’”

Critics of the move cite contaminated soil found at the former gas production site.

The local government paid a whopping 86 billion yen ($833 million) in cleanup costs but Koike said she wants to wait for the results of water testing in January.

Koike would not say if she would consider scrapping the relocation altogether if the test results are bad.

“I want to wait for the examinations being done by the project team,” she said.

Koike also questioned the 588 billion yen in relocation costs, 36 percent higher than earlier estimates.

These costs include relocating the market to a less-central location several kilometers away and building a modern facility about 40 percent larger with state-of-the-art refrigeration.

Japanese media have reported that postponing Tsukiji’s move would cost about seven million yen a day, and could delay construction of a highway connecting the current site with an athletes’ village being built for the city’s 2020 Olympics.
