Ōsanbashi Pier 大さん橋 is the main international pier at the Port of Yokohama, located in Naka Ward, Yokohama, Japan. Ōsanbashi is the oldest pier in Yokohama, originally constructed between 1889 and 1896.
To meet modern demands, Ōsanbashi was reconstructed between 1987 and 2002. The newly reconstructed passenger terminal is named the Yokohama International Passenger Terminal, designed by Foreign Office Architects. The departure/arrival lobby, ticketing booth, customs, immigration, shops and cafe are all on the 2nd floor of this terminal. There is an observation deck open to the public, on the rooftop.
