text: The character of Dōtonbori became defined in 1621 when the Tokugawa Shogunate instituted urban planning and designated Dōtonbori as the entertainment district of Osaka. Yasui Kuhē is credited with luring playhouses and performance tents to the district, and the theatre owners rewarded the Yasui family by reserving a box for each performance. By 1662, the avenue boasted six Kabuki theatres and five Bunraku theatres, as well as the unique Takeda Karakuri mechanical puppet theatre. Many restaurants and cafes were built to cater to the flood of tourists and entertainment-seekers pouring nightly into Dōtonbori.
  Modern development
  Over the years, declining interest in traditional forms of entertainment led to the closing of most of Dōtonbori's original attractions. With the exception of the , its remaining theatres were all destroyed during World War II.
  A redevelopment project was started in the 1960s to improve water quality in the canal. Land on the north and south banks was reclaimed to raise the river walls, and to partially fund the project, half the reclaimed land was sold to the owners of the land next to the canal. The other half was designated as a greenbelt parkway. The Dōtonbori Trial began when the descendants of Yasui Kuhē, one of the two people who had completed the canal in 1615, filed suit against the city and prefectural governments over ownership rights to the land along the canal.
  Further development of the land bordering the canal began in 2001, and the  between Tazaemonbashi and Ebisubashi was opened to the public in 2004. Prior to that time, development along the canal primarily focused on the streets parallel to it (Dōtonbori Street on the south bank, and Sōemonchō Street on the north bank), and very few storefronts faced the canal itself.
