In response to the novel coronavirus epidemic that continues to escalate, a group of Japanese members of Congress plan to establish a cross party alliance, urging the government to build hospital ships to treat patients and reduce risks at sea. According to Japanese media reports, the cross party alliance will be set up on February 27, sponsored by the former finance minister he fuzhilang and other seven party and nonpartisan members of the people's Republic of China, constitutional democracy and the Communist Party. Alliance officials pointed out that in view of the risk of infection when sending infected patients to land-based medical institutions during the Diamond Princess incident, it is necessary for the government to "introduce hospital ships that can be used for emergency treatment at sea as soon as possible". The bipartisan alliance will strive to submit relevant plans in the form of legislation by members of Parliament at this session, hoping that the Japanese government can use hospital ships to respond to large-scale disasters or infectious diseases in the future. The cross party Forum on building hospital ships was held on March 3. It is understood that as early as after the Persian Gulf crisis in 1990 and the great sakazaki earthquake in 1995, Japan has proposed to build a hospital ship. After the earthquake in East Japan in 2011, Japanese legislators again proposed the construction of hospital ships, and the government later used ship demonstration experiments, and completed the report in 2013, believing that it is feasible to use the existing civilian ships and patrol boats of the maritime security department as hospital ships, but due to cost and other issues, it has not been realized yet. According to Japanese cabinet estimates in 2013, the cost of building a hospital ship ranges from 14 billion yen (about 889 million yuan) to 35 billion yen (about 2.224 billion yuan), and the annual operation and maintenance costs range from 900 million yen (about 57 million yuan) to 2.5 billion yen (about 159 million yuan). At present, the Japanese Maritime Self Defense Force does not have a professional hospital ship at present, but adopts the quasi hospital ship system, and sets up medical facilities on as many large surface ships as possible to make them become quasi hospital ships, which are used to solve the daily needs of medical service during maritime navigation. However, the quasi hospital ship mechanism has no effect in the face of sudden outbreaks There is no ship that can be used as a hospital ship in Japan. The ship closest to the concept of "hospital ship" is the "jishengwan" owned by the civil society "jishenghui". The ship is only a small ship with a displacement of more than 180 tons and a length of about 33 meters. At best, it can only be regarded as a "water clinic". Previously, Japan's health and Labor Minister Kato Shengxin had put forward the plan of "hospital ship" in the House Budget Committee on February 12. At that time, he said that the Ministry of health, labor and welfare was considering the use and deployment of hospital ships with hospital functions, "at present, discussions are under way with other departments of the government, which will accelerate the implementation and implementation of this plan.". Novel coronavirus pneumonia and other major natural disasters are being addressed by Japanese defense minister Kawano Taro, who is considering building a hospital ship in February 14th. The budget, staffing and ownership of the unit are being assessed.
