Hailam Street (Hainan Street) was named for its majority Hainanese Chinese population, but at the beginning of the 20th century it was also notorious for its Japanese karayuki-san brothels. The area was known to its Japanese residents as Chuo Dori or 'central street'. The Japanese prostitution industry began to wind down after World War I under pressure from the Japanese authorities. The area comprised many dilapidated two storey shop houses, the last of which were demolished in the early 1980s. Today the old street is incorporated within Bugis Junction, a pedestrian shopping mall made up of three streets - Malabar Street, Malay Street and Hylam Street. The streets are the first in Singapore to be air-conditioned and are thus commonly refered to as 'indoor streets'.
