Century motor vehicles, designated "Empresses", for exclusive use of the Imperial Household. In 2006, the Imperial Household Agency took delivery of the first of four bespoke Toyota Century Royals. The first of these specially prepared vehicles, Empress 1, serve as the official state car of the Emperor. Two Century Royals, Empress 3 and Empress 5, were assigned to the Ministry of Foreign Affairs for special use by visiting dignitaries and foreign heads of state. The last, Empress 2, was built in 2008 as a hearse exclusively for imperial funerals. Despite the imperial family's extravagant expenditures, there is a limitation with travel expenses since the Emperor's entourage pays a maximum of £110 a night, regardless of the actual cost of the hotel. Hotels accept it since they regard it as an honour to host the Imperial Family. Aside from the inner court (the Emperor and Empress, and their children including the Crown Prince and Crown Princess), the civil list covers an additional 19 family members who live in imperial residences. They are not prohibited from holding jobs or running businesses. For example, Prince Tomohito of Mikasa, his wife and two daughters receive £310,000 per year, but they are not well known by the Japanese public and have few imperial duties. The real annual cost was estimated to be $325 million per year, also . Involvement in War World War II Members of the imperial family, including Naruhiko, Prince Higashikuni, Yasuhito, Prince Chichibu, Takahito, Prince Mikasa and Tsuneyoshi, Prince Takeda, were involved in human experimentation programs in various ways, which included authorizing, funding, supplying, and inspecting biomedical facilities. Since 1978, the emperor of Japan has never visited Yasukuni Shrine due to Emperor Shōwa's displeasure over the enshrinement of convicted Class-A war criminals. Support A 1997 survey by Asahi Shimbun showed that 82% of Japanese supported the continuation of the monarchy. Polls after showed of respondents were "indifferent" towards it. The imperial system is considered a symbol of the country, it provides a sense of linkage, purpose, spiritual core, diplomatic role as ambassador and a source of tradition and stability. A small percentage argue that the imperial system is out of date, not in sync with the contemporary times.
