The relocation site of the world-famous Tsukiji Fish Market has been contaminated with far more toxic chemical materials than previously thought and around 2 meters of surface soil will probably have to be replaced, an advisory panel to the Tokyo Metropolitan Government said Monday. The metropolitan government is planning to relocate the market by 2013 to the Toyosu area of Koto Ward because the Tsukiji site has become too crowded and facilities there have aged. Gov. Shintaro Ishihara indicated the relocation plan could be delayed due to the contamination problem.
