Tokyo Gov. Yuriko Koike's Tuesday announcement that the city plans to retain both the Tsukiji fish market and the planned relocation site in the Toyosu district sparked some pointed questions over how the capital will be able to fund the plan.

Koike said Tokyo will redevelop the Tsukiji site in five years, after moving the fish market to a designated site in the nearby Toyosu area as planned. The Tsukiji site will eventually be turned into a wholesale market with a culinary theme park so it could remain a tourist attraction.

The Tokyo Metropolitan Government had planned to sell the site in Tsukiji to cover the debt issued for construction of the Toyosu market. Koike said she will now consider how best to repay the debt.
