This report is currently only published in Japanese, and key lessons learned from the unprecedented operation are self-complacent. A lack of accountability and transparency is still obvious in Japan's domestic response to The outcome of the Diamond Princess operation suggests that raising preparedness for health emergencies in enclosed spaces is vital. Several COVID-19 outbreaks have been already reported in cruise ships, and preventing further outbreaks and improving its management are critical. International solidarity is pivotal in the COVID-19 response, 5 and Japan, a promoter of global health security, must take initiative to promptly share scientific insights of COVID-19 in enclosed spaces; scrutinize the previous unprecedented operation; openly summarize challenges in infection control, health communication, governance, international law, or other realms; and act on lessons learned. Launching an independent panel and conducting an external evaluation will help achieve this process. This will not only strengthen Japan's preparedness and response toward emerging infectious diseases, but also globally improve future responses toward health emergencies in cruise ships, mitigate their impact, and protect the health of passengers and crews.
