Japan navigated the COVID-19 pandemic with a distinctive approach, differing from many Western nations. Despite its densely populated urban centers and a delayed vaccine rollout, the country initially contained the virus effectively. This involved voluntary public cooperation, targeted measures, and an evolving public health strategy.
Japan’s Initial Response and Unique Strategies
Japan’s early response centered on a “cluster-based approach,” focusing on identifying and containing localized outbreaks rather than widespread lockdowns. This strategy involved intensive backward contact tracing to pinpoint infection sources and prevent further spread. An expert panel guided these efforts, analyzing data to understand transmission patterns.
This approach emphasized avoiding the “Three Cs”: closed spaces with poor ventilation, crowded places, and close-contact settings. Public health authorities widely disseminated this concept, encouraging voluntary social distancing requests, or jishuku yōsei, rather than legally binding mandates. This framework, which proved effective in early containment, was later adopted by the World Health Organization.
Vaccination Rollout and Evolving Public Health Measures
Japan’s vaccination program began later than many other developed economies, with Pfizer-BioNTech vaccine approval in February 2021 and Moderna and AstraZeneca in May 2021. The initial rollout prioritized frontline medical workers in February 2021, followed by individuals aged 65 and older starting in April 2021. Despite this slow start, Japan achieved high vaccination rates, with approximately 80% of the population receiving two doses and 67% a booster.
As the pandemic progressed and new variants emerged, Japan’s public health measures evolved. The government frequently declared “quasi-states of emergency,” allowing prefectural governors to implement stricter measures such as reduced operating hours for businesses. Mask-wearing remained a strong social norm throughout the pandemic, even when only recommended. Testing strategies also adapted, incorporating antigen tests alongside PCR testing to detect cases earlier.
Societal and Economic Impact
The COVID-19 pandemic significantly impacted Japan’s society and economy, particularly the tourism and service industries. International tourism experienced a drastic decline, with foreign visitors dropping from over 30 million in 2019 to approximately 245,862 in 2021 due to travel restrictions. This decline resulted in substantial economic losses, impacting hotels, restaurants, and related services.
The postponement of the Tokyo 2020 Olympics to 2021 and its staging with limited spectators also incurred considerable economic costs. The spectator ban led to an estimated loss of 1.4 trillion yen in potential GDP. The pandemic also accelerated changes in work culture, with increased adoption of remote work practices across various sectors.
Transition to Endemic Management
Japan officially reclassified COVID-19 from a Class 2 infectious disease to a Class 5 disease under the Infectious Disease Law on May 8, 2023. This change places COVID-19 on the same legal footing as seasonal influenza, signifying a shift towards endemic management. The reclassification was based on the disease becoming less lethal and no longer warranting the same level of governmental intervention.
The implications of this reclassification include a shift in medical care provision, with COVID-19 treatment transitioning to a broader range of medical institutions, and patients now bearing a portion of medical expenses through health insurance. Government support for testing and treatment has been reduced, and the legal basis for recommending hospitalization or declaring states of emergency has been removed. This signifies Japan’s transition towards living with the virus, with continued emphasis on individual responsibility for infection prevention.
