Japantown, also known is Nihonmachi, is a neighbourhood in San Francisco.

It is one of three Japantowns remaining in the States, all of which are in California (other two are Los Angeles and San Jose).

The focal point is Japan Center, a shopping complex. The complex is made up of three buildings. They are the Kinokuniya Mall, Japan Center West (Kintetsu Mall ), and Japan Center East (Miyako Mall).

Located between the East and West Malls is the Peace Plaza with the Peace Bagoda, which is a five tiered concrete stupa. It was designed by Yoshiro Taniguchi and presented to San Francisco by its sister city Osaka, Japan in 1968.

Japantown is bordered roughly by Geary Boulevard between Laguna Street in the east, and Fillmore Street in the west.
