Asakusa in the Taisho Era

Postcard: "Asakusa Park Rokku District" 1919

The Origins of Asakusa: Beloved Across the Ages

Taisho-era Asakusa could perhaps be described in a word as a street where entertainment and culture accumulated—like a great exposition. Taisho Asakusa gathered not only movies but also Asakusa Opera, comedy shows, Yasugi-bushi performances, Hanayashiki amusement park, aquariums, insect museums, and other entertainments of the time. The route from Nakamise through Sensoji Temple worship to the Rokku entertainment district was a standard Tokyo sightseeing course.

The Asakusa area centered around Sensoji Temple had been known since the Edo period as one of Japan's premier entertainment districts. In what was then called Okuyama within the Sensoji Temple grounds, various sideshow booths were set up, attracting many daily visitors who came to enjoy elaborate crafts, acrobatics, and exotic animals.

When the Meiji era began, the Sensoji area was designated as "park land," and redevelopment took place including the excavation of a large pond (Hyotan Pond) and construction of a brick Nakamise shopping street. Sideshow entertainment was moved to the newly established Asakusa Park Rokku district, forming an entertainment quarter. When motion pictures (movies) appeared in the 1890s, sideshow booths one after another converted to movie theaters.

Asakusa Rokku at that time had building height restrictions, and high-rise buildings pushed these limits to the maximum. Buildings with themes—such as one topped with a globe in keeping with its name "World Theater," or the "Opera House" modeled after the Paris Opera—lined up in a manner that could indeed be likened to an exposition. Most of these buildings were wooden structures with plaster coating and were rebuilt over short periods, but almost all were lost in the Great Kanto Earthquake of 1923. (Edo-Tokyo Museum)
