会場建設費６００億円上振れ　２５年大阪・関西万博―井上万博相

　井上信治万博担当相は１１日の閣議後記者会見で、２０２５年開催の国際博覧会（大阪・関西万博）の会場建設費が当初より６００億円上振れし、最大で１８５０億円になるとの試算を公表した。暑さ対策の強化などが主な要因。井上氏は同日夕、大阪府・市を訪れて吉村洋文知事と松井一郎市長に説明する。
　日本国際博覧会協会が試算したもので、年内に策定する基本計画に盛り込む。上振れの要因は▽暑さ対策のミストやトイレなどの整備（３２０億円）▽迎賓館に併設する日本庭園、レストランや物販施設などの整備（１１０億円）▽会場のメイン通りに設置する大屋根の設計変更（１７０億円）―。
　建設費は国と府・市、経済界が３分の１ずつ負担するルールで、それぞれ２００億円の負担増となる。井上氏は会見で「今回の金額は上限であると考えている」と述べ、今後の詳細設計や契約、工事の各段階でコスト削減に努める考えを示した。（2020/12/11-12:20）

Construction costs for the venue of the 2025 World Exposition in the western Japan city of Osaka are expected to be 60 billion yen more than initially planned, Shinji Inoue, minister for the event, said Friday.
   The additional costs, mainly for reinforcements to measures against the summer heat, are expected to raise the total costs to up to 185 billion yen, he told a press conference.
   The new cost estimate, calculated by the Japan Association for the 2025 World Exposition, will be included in a basic event plan to be compiled by the end of this year.
   Of the additional expenses, 32 billion yen will be for setting up mist-spraying devices and other measures against the heart, as well as restrooms and other facilities, 11 billion yen for facilities, such as a Japanese garden to be built adjacent to a guesthouse, and restaurants and stores, and 17 billion yen for changes to the designs for a roof to be built over the main street of the venue.
   The construction costs are set to be shouldered equally by the central government, Osaka Prefecture and the city of Osaka, and the business circle, meaning that the financial burden of each will increase by 20 billion yen.
