This Osaka trivia quiz covers Japan's great merchant city, from its days as the imperial capital of Naniwa and the port of the Kofun kings, through Toyotomi Hideyoshi's gold-leafed castle and the siege that ended the Toyotomi clan, to the industrial boom of the Meiji era, the B-29 raids of 1945 and the postwar rise that brought Expo '70, the Kaiyukan aquarium, Kansai International Airport and Universal Studios Japan. There is plenty on the Osaka everyone visits today: the Glico Man and crab signs of Dōtonbori, takoyaki and okonomiyaki, the kuidaore proverb, Tsūtenkaku and its Billiken, Shitennō-ji, Sumiyoshi Taisha, the Tenjin Matsuri, Abeno Harukas, the Umeda Sky Building, bunraku puppet theatre, the Hanshin Tigers and their Curse of the Colonel, and the Yumeshima island of Expo 2025.
