Tokyo Gov. Yuriko Koike announced Friday that she will decide in summer whether to relocate Tsukiji fish market to the alternative Toyosu site in Tokyo's Koto Ward, further delaying the long-troubled move originally scheduled for Nov. 7 this year.

At the earliest, the relocation will take place sometime between winter next year and the spring of 2018, Koike said.

The governor did not rule out the option of scrapping the whole plan, which has been suspended on fears of soil pollution at the Toyosu site. The current Tsukiji market, which is famous worldwide, is located near the Ginza shopping district in Chuo Ward.
