Cruise Princess adds second ship for Japan market By Tom Stieghorst / January 23, 2013 Share 1 -- Princess Cruises will expand its efforts to source cruise passengers in Japan by home-porting a second ship there for a seven-month season in 2014. The Diamond Princess will join the Sun Princess in Japan and the two ships will sail from a combination of three home ports: Yokohama, Kobe and Otaru (near Sapporo). Princess said it expects the ships to carry at least 100,000 passengers on 42 cruises between April and October. Sailing seven- to nine-day itineraries, they will visit more than 20 ports in Japan, South Korea, Russia and Taiwan. "We continue to believe there is substantial untapped demand for cruise vacations here," said Princess President Alan Buckelew. The 2,670-passenger Diamond Princess was built by Mitsubishi Heavy Industries in Nagasaki, Japan, and is one of the few big cruise ships delivered by a non-European shipyard. It is scheduled to sail in Alaska between May and September this year. Follow Tom Stieghorst on Twitter @tstravelweekly.
