A buyer at the world's biggest fish Market in Tsukiji, Tokyo inspects pieces of tuna displayed inside a glass case at the market. More than 2,300 tons of fish -- about one-third of the total consumed in Japan -- passes through Tsukiji each day and the market offers more than 450 varieties of marine products. The market, which dates back almost 75 years, is slated to move to a high-tech site on a man-made island in Toyosu, which is well-documented as being contaminated with benizine. Not that Tsukiji is much better off -- many buildings in the aging site are stuffed with asbestos. "Choose your poison," says one Tsukiji official. The new site, which the government plans to be readied by 2012, will be significantly larger, with more room for off-loading and for sellers to display their goods. The current location, says one official, is too cramped and collisions between motorised carts and pedestrians means accidents occur almost daily. Meanwhile, with fish sales down, it is becoming more difficult to justify Tsukiji's prime location and property developers are keeping a close watch on Tsukiji land, which is just a few blocks from the ritzy Ginza district of Tokyo, where per-meter land prices are among the highest in the world...The move to the new Toyosu location, meanwhile, has been at the center of heated debate -- clean-up operations alone are estimated to cost ¬?67 billion (around US$660 million), with a further ¬?450 billion to build a new marketplace. Big wholesalers favour the move, but the 1,600-plus merchants mostly are against it. Yoshiharu Kikuraku, a Tsukiji storeowner who began working at the market 60 years ago, expresses bewilderment at the plans, saying that the name Tsukiji itself has become synonymous with the world's best and most eclectic selection of fish. "This place has a long tradition. Why break it and start from scratch all over again?" he says.
