Yokohama, just to the south of Tokyo, is home to one of the largest, most vibrant Chinatowns in the world. It's quite compact, covering an area just half a kilometer across, but its streets are lined with more than 600 restaurants and shops. Over 21 million visitors come here every year. In the center of Yokohama Chinatown stands a temple called Kanteibyo, which was erected in honor of the deity Guan Yu. To mark the 150th anniversary of Kanteibyo this year, there have been major celebrations. On this edition of Journeys in Japan, our reporter Gow explores this fascinating district, samples the delectable cuisine in some restaurants, and reports on the colorful festivities.
