Prefectural and municipal governments that will host events for the 2020 Olympics jointly warned the organizing committee and the Tokyo Metropolitan Assembly on Monday not to shift policy and force them to shoulder some of the costs of constructing facilities.

Leaders of 10 governments — six prefectures including Kanagawa, Miyagi and Shizuoka, and four major cities near Tokyo — submitted a letter to Yoshiro Mori, president of the 2020 Olympics organizing committee, and Tokyo Gov. Yuriko Koike.

The letter calls for a reaffirmation of the policy, adopted in 2013 during the bidding for the games, that the committee will cover expenditures for the construction of temporary facilities.
