Earlier this month, Osaka Gov. Ichiro Matsui led a delegation of local politicians and business leaders to Paris, where they formally announced at a general assembly of the Bureau International des Expositions that the prefecture was bidding to host the 2025 World Expo.

Speaking to the assembled delegates, who will decide the winner in November 2018 after conducting site visits over the next year or so, Matsui introduced the Osaka bid, but did not delve into specifics. Prime Minister Shinzo Abe also delivered a video message of support. Paris, home to the bureau, is also bidding for the event, along with Ekaterinburg, Russia and Baku, Azerbaijan.

Why was the name, originally the Osaka Expo 2025 bid, changed to the Osaka Kansai Expo 2025 bid?
