Nippon Yusen, also knownas NYK Line, is a Japanese shipping company and is a member of the Mitsubishi keiretsu. The company has its headquarters in Chiyoda, Tokyo, Japan. It has a fleet of about 800 ships, which includes container ships, tankers, bulk and woodchip carriers, Ro-Ro car carriers, reefer vessels, LNG carriers, and cruise ships.
By the mid-1950s NYK ships were again seen around the world.
As the demand for passenger ships dwindled in the 1960s, NYK expanded its cargo operation, running Japan's first container ship Hakone Maru on a route to California in 1968 and soon establishing container ship routes to many other ports. NYK became a partner in Nippon Cargo Airlines in 1978, and in 1985, added United States container train service in cooperation with Southern Pacific.
NYK revived its passenger ship business in 1989 with cruise ships operated by its newly formed subsidiary Crystal Cruises.
In 1990 NYK resumed passenger services under its own name when MS Asuka entered service on the Japanese cruise market. In 2006 Asuka was replaced by the much larger Asuka II, formerly Crystal Cruises' Crystal Harmony.
At the end of March 2008, the NYK Group was operating about 776 major ocean vessels, as well as fleets of planes, trains, and trucks. The company's shipping fleet includes around 155 containerships, 286 bulk carriers, 55 woodchip carriers, 113 car carriers, 21 reefer carriers, 78 tankers, 30 LNG carriers, and three cruise ships. NYK's revenue in fiscal 2007 was about US$26 billion, and as a group NYK employs about 55,000 people worldwide. The company has offices in 240 places in 27 countries, warehouses on nearly every continent, and harbor operations in Asia, North America, and Europe. NYK head office is based in Tokyo, and has regional headquarters in London, New York, Singapore, Hong Kong, Shanghai, Sydney, and São Paulo.
During the first decade of 2000s, NYK reached a remarkable position within the Liner ranking, as one of top twelve companies in the number of containers carried, number one RORO Carrier, and one of the main player in LNG and break bulk transport fields, plus several prominent awards for its cruise service quality.
In April 2014, eight container sister ships of a new series were commissioned, and two more units were inserted as options in the construction contract. Both options were converted into firm orders in July 2014. The building began in spring 2015 at the shipyard Japan Marine United in Kure, Hiroshima. The first delivered ship of the ten units to be built within end of 2018, was mv NYK Blue Jay launched in 2016. All 10 vessels received names of bird species (therefore called the NYK-bird class). The ships are used on the European Far East route and are the largest container ships built in Japan so far, having a maximum container capacity of 14,026 TEU.
