This downtown area in southern Osaka City is famous for Tsutenkaku Tower, Janjan Yokocho Street, and its giant pufferfish lantern sign. The origins of Shinsekai date back to 1903, when the 5th Domestic Industrial Exposition was held in Tennoji and the area now known as Shinsekai. Tennoji Park was built on the eastern half of the site, while the remaining western half was occupied by the iconic Tsutenkaku Tower (the first one) and the paid amusement park Luna Park to its south. This marked the beginning of the development of Shinsekai, with theaters, movie theaters, and other establishments gathering there. While both Luna Park and the movie theater are now closed, Tsutenkaku Tower 's observation deck continues to attract visitors from far and wide. Every Monday, regional singers perform enka at Tsutenkaku Tower Theater located underground, and every Saturday and Sunday, Tsutenkaku Tower Theater TENGEKI entertains audiences with manzai and Kamigata rakugo. On Saturdays and Sundays, Shochiku entertainers also perform rakugo and manzai. Janjan Yokocho, a lively street lined with about 50 shops, including kushikatsu restaurants, doteyaki restaurants, and go and shogi clubs, stretches 130 meters from north to south. On weekends and holidays, it is visited by large numbers of tour groups, who enjoy taking commemorative photos with Billiken and pufferfish lantern signs in the background.
