Tokyo Gov. Yuriko Koike on Friday said she would seek answers in court as to whether her predecessor Shintaro Ishihara was the chief cause behind the Tsukiji fish market relocation fiasco.

The comments mark a departure from the metropolitan government's pervious stance that Ishihara was not responsible.

Koike said she believes that clarifying all the facts and determining whether Ishihara bears responsibility for the alleged illegal acquisition of the Toyosu site is essential to enhance administrative reforms.
