Tokyo Gov. Yuriko Koike has reportedly decided to postpone the planned November relocation of the famed Tsukiji fish market amid ongoing concerns over soil contamination at the new Toyosu site.

Koike will reach a decision after groundwater test results are released in January, Kyodo News and some other media outlets said Tuesday.

The famous market in Chuo Ward was scheduled to close its doors Nov. 2 and re-open Nov. 7 at the new multistory site standing on 400,000 sq. meters of land in Toyosu on Tokyo Bay.
