The ship instead will spend the summer sailing from Australia, Princess Cruises said.“Moving Sun Princess to Australia in 2015 doesn’t diminish our enthusiasm for the Japan cruise market. As demand for cruising grows further in Japan, we will review the opportunity to add additional capacity in the future,” said Jan Swartz, Princess Cruises president.Beginning next April, the Diamond Princess will operate 20 departures from Yokohama and Kobe. There will be three-, four- and five-day itineraries for travelers desiring quick getaways.New for 2015 from Kobe is a 10-night Hokkaido cruise that includes the northern destinations of Aomori, Hakodate, Otaru and Abashiri.The Diamond Princess, which is currently sailing its second season in Japan, just underwent a $30 million renovation. A sushi restaurant and a Japanese bath with indoor and outdoor bathing areas were added.
