Kabukicho, located on the east side of Shinjuku, is one of the more famous red light districts in Tokyo. There are over 3000 registered bars, and at least 1000 of them are Taiwanese-owned. In the late 1970s, over 10,000 Taiwanese women left for Japan for work and wealth. Most of them settled in Shinjuku. The women worked over 20 years at bars to send money back home.
