The Tokyo Metropolitan Government on Friday decided to proceed with the relocation of the famed Tsukiji fish market to Toyosu as early as next spring but retracted a decision to cleanse the toxic water beneath the new site to safe levels before it reopens.

In another major decision, it also said the Metropolitan Expressway in Nihonbashi would be moved underground.

The timing of the Tsukiji move may hinge on the businesses there, Tokyo Gov. Yuriko Koike said when asked if it could open in May.
