Huis Ten Bosch (theme park)  The park features many Dutch-style buildings such as hotels, villas, theatres, museums, shops and restaurants, along with canals, windmills, amusement rides, and a park planted in seasonal flowers. Huis Ten Bosch, which opened on March 25, 1992, is located on Hario Island in the southern part of Sasebo, facing Ōmura Bay. Its location reflects historical relations between the Netherlands and Japan , which began in 1609 when a trading post was opened by the Dutch in Hirado, not far from Sasebo. The park is open daily from 9.00 a.m. to 9.30 p.m. (9.00 a.m. to 8.30 p.m. from December to February). A day "passport" ticket, covering entry and a number of attractions within the park costs 5,600 yen for adults and 4,400 yen for children. The park can be reached by JR train or bus from Nagasaki. It can also be reached by boat from Nagasaki Airport or from Sasebo. The park recorded the peak of 4.25 million visitors in 1996. However, due to the fall of the number of visitors caused by economic slump in Japan, the park declared bankruptcy in 2003 with debt of 220 billion yen. The rebuilding plan was sponsored by Nomura Principal Finance Company until March 2010, when H.I.S., a travel agency, took over the management by injecting 2 billion yen. The park was the setting for the 2004 anime series, "The Marshmallow Times". In 2015, the Henna Hotel ("Strange Hotel") opened on site. It is the world's first hotel staffed by robots, although humans will initially work alongside them.
