Colonized by the Spanish and later inhabited by a number of Japanese immigrants, West Los Angeles was originally its own municipality known as Sawtelle. In 1922, Sawtelle was annexed by the City of Los Angeles. Today, West Los Angeles is a largely affluent community, home to about 30,000 residents. In addition to its residential areas, West LA is home to a number of commercial developments, including some high-rise office buildings along its main corridors. It continues to maintain a strong Japanese community and business district along Sawtelle Boulevard.
