While prostitution is technically illegal in Japan under the Prostitution Prevention Law of 1956, "red light" districts exist in a legally gray area often referred to as entertainment districts or fuzoku. The most famous of these is Kabukicho in Shinjuku, Tokyo, known for its neon lights, host and hostess clubs, and "love hotels." Another prominent area is Tobita Shinchi in Osaka, which is one of the oldest and most traditional-looking districts where establishments operate under the guise of "restaurants" to circumvent legal restrictions. Other notable areas include Susukino in Sapporo and Nakasu in Fukuoka. These districts are generally safe for tourists to walk through during the day or evening, as they are heavily integrated into the broader nightlife and dining scenes of Japanese cities. However, visitors should be wary of "touts" or street hawkers who may try to lure people into bars with the promise of cheap drinks, which can sometimes lead to exorbitant "seating fees" or scams. While the vibe can be intense, these areas are a fascination for many due to their unique blend of gritty urban subculture and traditional Japanese "nightless city" history.
