Visit Japan without a passport, sip a cup of java and jive to some jazz where the Far East meets the “Harlem of the West.” Founded in 1906 Japantown is the oldest in the United States and one of only three remaining. This small slice of Japanese life is just a few octaves away from the Fillmore, the “Harlem of the West,” which is witnessing a revival of its jazz heritage and is the setting for an annual open-air jazz festival. NOPA, an acronym for north of the (Golden Gate Park) panhandle, has been dubbed an “urban frontier” by The New York Times and is increasingly on the foodies’ GPS for late night suppers.
