Commentary: Stranded cruise could be helped if Japan had hospital ships

A floating hospital can also advance Japan’s interests in the region and ability to respond to disasters at home, says Akimoto Daisuke.

TOKYO: A curious anomaly in Japan is that official hospital ships have not been built or used since the end of the World War II.

This is despite the fact that Japan has regular disasters, such as earthquakes, typhoons, tsunamis, volcano eruptions and floods.

In such devastating disasters, medical assistance by hospital ships at sea would be of tremendous assistance particularly when hospitals, medical services, and transportation networks on land are inoperable.

Indeed, the coronavirus crisis aboard the Princess Diamond cruise ship is a case in point. About 3,000 passengers and 1,000 crew members are stuck off Yokohama aboard the cruise ship that was sailing around the East Asian region.

The identification of those infected and the isolation process could probably have been handled more effectively and efficiently by a medical team based on a hospital ship that could reach the cruise ship before it reached shores. Why is it so difficult for Japan to possess hospital ships?


In most countries, hospital ships belong to their military forces. USNS Mercy and USNS Comfort, for example, are operated by the US Navy. 

But this option is tough to pursue given complications surrounding the fact that the Japanese Self-Defense Forces are not classified as “military” under Article 9 of the Japanese Constitution.

Another problematic issue is that there is no legislation for ships to conduct medical care beyond a certain prefecture in Japan. As such, the Ministry of Health, Labour and Welfare cannot authorise ships that can act as hospitals.

More critically, building hospital ships and maintaining medical doctors and nurses on hospital ships is an expensive business, and requires budgetary support during a period of spiraling debt and government austerity measures.

Nonetheless, Japan needs hospital ships for three reasons.

First, medical assistance by hospital ships could be vital for future disaster relief efforts, and contribute to aiding Japanese citizens and advancing Japan’s national interests.

In fact, the Japanese government has forecast a 70 per cent chance that a massive metropolitan earthquake of a magnitude of 7.3 (with a death toll of approximately 23,000), and a Nankai trough earthquake with a magnitude of 8 to 9 (with a death toll of approximately 323,000) could happen within 30 years.

Second, Japan’s hospital ships would be able to contribute to international cooperation, especially humanitarian assistance and disaster relief in the event of devastating events in the Asia-Pacific region.

Third, Japan’s possession of hospital ships would strengthen Japan-US relations on the basis of the bilateral military alliance. Japan’s hospital ships would be able to conduct educational exchanges and medical training in preparation for future national disasters.

As the rotation and dispatch frequency of US hospital ships for international humanitarian assistance and disaster relief is limited, Japanese hospital ships could supplement the role played by US hospital ships in the Indo-Pacific region.


Attempts have been made to develop hospital ships without success so far. One month after the March 2011 earthquake in Japan, for example, the All-party Parliamentary Group to Build Hospital Ships was established.

According to the president of the parliamentary group, Seishiro Eto, of the Liberal Democratic Party (LDP), the group planned to initiate legislation to enable the building of hospital ships.

Within three years however, the lack of resources and bureaucratic support led to the group’s demise. Without an appropriate legal basis and an approved budget, it will be impossible for Japan to create hospital ships from scratch.

A second attempt took the form of the Parliamentary Group to Consider the Future of Disaster Medical Care of Japan as a Maritime Nation, established in March 2014 by the ruling coalition parties, the LDP and Komeito.

In response to the request by the parliamentary group, USNS Mercy (the largest hospital ship in the world), docked at Ota ward in Tokyo in June 2018 to host an inspection tour by Japanese lawmakers, government officials and medical experts.

In March 2019, Fukushiro Nukaga, a Diet member of the LDP and the president of the parliamentary group, announced a draft outline of new legislation.

Building and maintaining hospital ships from scratch is costly, but the new legislation will enable the Japanese government to use already-existing official or private ships as “multi-purpose disaster-relief medical ships”.

The legislation needs to be supported by Diet members of both ruling and opposition parties. This may require the expansion of the parliamentary group with strong bipartisan support that will have a greater chance of success in enacting the new legislation in 2020.

Japan needs to overcome its financial and bureaucratic obstacles in order to possess national or private hospital ships or multi-purpose disaster-relief medical ships.

Given the regular occurrence of disasters in Japan, medical ships have the capacity to save a large number of lives in Japan, and in the Asia Pacific region.
