Japan’s COVID-19 death rate is the lowest among the world’s wealthiest nations, with health experts pointing to continued mask wearing, extensive vaccination and an already healthy population as the core factors behind its success.
The population has continued to adhere to basic infection control measures, including avoiding crowds and poorly ventilated venues, as other parts of the world grapple with pandemic fatigue. Japan’s measures have also been bolstered by a robust vaccination program and free medical care.
However, what truly sets it apart from many places, particularly Asian neighbors like China, is it has managed to limit deaths without mandates and with few restrictions. The constitution prevents imposing lockdowns backed by police actions, meaning that even during a state of emergency the government puts the onus on businesses and individuals to change their behavior.
That soft approach has had remarkable results. Japan’s COVID-19 deaths per capita is 246 per million people, the lowest out of the 38 members of the Organisation for Economic Co-operation and Development (OECD), according to Our World in Data.
It is all the more significant given that Japan has the highest proportion of elderly people — typically some of the most vulnerable to COVID-19 — in the world. New Zealand’s rate, previously the lowest, sits at 257 per million after the country faced its first substantial virus wave upon opening up and lifting curbs.
To be sure, capturing an accurate picture is difficult as reporting standards differ country-by-country. The WHO has said Japan’s excess deaths declined through 2020 and last year, while a study published in The Lancet in March said excess mortality in the country was six times higher than reported COVID-19 fatalities during 2020 to last year. There were about 9,000 fewer deaths in 2020 than in 2019, although that rebounded last year, government figures show.
While every nation has its own standard for identifying COVID-19 deaths and different testing policies that can make comparisons difficult, Japan’s low rate of fatalities shows its strategy works, said Takao Ohmagari, head of the disease control and prevention center at the National Center for Global Health and Medicine, and an adviser to the Tokyo government.
Japan’s measures might hold lessons for how other countries can deal with the current or future pandemics. Here is what experts say the country got right:
SOCIAL COMPLIANCE
Japan’s virus-fighting strategy relied on the population complying willingly with social distancing guidance, particularly when cases were rising. This proved more effective than top-down measures in other places, which in some cases made people resistant and defiant.
“People are using their own judgement to avoid risk and modify their behavior, and this plays an extremely important role,” Ohmagari said.
That includes wearing masks, which was embraced during the early days of the pandemic and remains almost universal even as the government relaxed its recommendation to wear one outdoors. Mask use in Japan has typically held above 90 percent, a threshold other G7 countries have only occasionally neared, Institute for Health Metrics and Evaluation data show.
The government’s “Three Cs” slogan — which touts avoiding closed spaces, crowded places and close-contact situations — has also reinforced how they want the population to act. In addition, buildings to taxis have undertaken efforts to improve ventilation, including the use of carbon-dioxide monitors to show that indoor air is being exchanged.
The relatively light nature of restrictions also meant that Japan did not face the extensive disruption to daily life of a harsh lockdown, deployed in countries from Italy to China and New Zealand at various times. That might have helped people comply with restrictions for longer and saw the nation avert the kind of social unrest seen overseas.
Moreover, even as other populations have rushed back to life as normal, the Japanese appear to remain cautious: Activities in Tokyo’s nighttime entertainment district is still down 40 percent from 2019, according to one estimate.
VACCINATION
Before the pandemic, the Japanese had one of the lowest rates of vaccine confidence globally, but they are now among the best-protected populations in the G7, swiftly catching up to countries like the US that had started their inoculation programs months earlier, and doing it without a mandate.
Experts have pointed to the initial slow roll out of vaccinations and an early shortage as creating a sense of urgency, especially among the elderly, while the act of inoculation was not politicized like it was in the US.
About 93 percent of Japanese aged 65 and older have had two shots, and 90 percent have had a booster, data from the Japanese prime minister’s office show. That compares with 81 percent of the total population having had two doses, and 61 percent receiving a third.
In the US, 94 percent of people aged 65 to 74 are fully vaccinated, and 88 percent of the population 75 and older have received two shots.
“Thanks to the protection Japanese people gained through vaccination and natural infection, I don’t expect Japan’s hospitalization or deaths to increase dramatically any time soon,” said Kenji Shibuya, an epidemiologist at the Tokyo Foundation for Policy Research.
HEALTHY POPULATION
A core pillar supporting the low death rate was the underlying good health of Japan’s population. The country has the longest life expectancy in the world, and was one of only six OECD members not to see a reduction in 2020. Just 5 percent of Japanese are obese, one of the conditions that increases the risk of severe illness from COVID-19, versus 36 percent of the population in the US and 28 percent in the UK, according to the World Obesity Federation.
Widely adopted actions such as mask wearing and hand washing also wiped out other illnesses like influenza, which typically killed more than 10,000 Japanese per year.
The country’s deaths were almost entirely people older than 60, indicating a solid baseline of health for middle-aged and younger cohorts. That contrasts with a wider distribution of fatalities in the US, where about one-quarter of deaths were in people younger than 65, according to government figures.
FREE CARE
Like most of the world, Japan’s healthcare system has been strained during surges of infections. However, it has managed to maintain a strong level of contact tracing during the pandemic that means resources can be sent where they are needed, for free.
A web of local public health centers trace cases, and find positive patients a hospital or hotel room which are free of charge. Those isolating at home are constantly contacted by the health center staff, who send out nurses and doctors if needed.
“We know that early intervention saves more lives,” Ohmagari said. “Although I feel there’s more we can do, Japan’s system tries to not leave anyone behind, monitors patients thoroughly and intervenes early.”
The Executive Yuan recently revised a page of its Web site on ethnic groups in Taiwan, replacing the term “Han” (漢族) with “the rest of the population.” The page, which was updated on March 24, describes the composition of Taiwan’s registered households as indigenous (2.5 percent), foreign origin (1.2 percent) and the rest of the population (96.2 percent). The change was picked up by a social media user and amplified by local media, sparking heated discussion over the weekend. The pan-blue and pro-China camp called it a politically motivated desinicization attempt to obscure the Han Chinese ethnicity of most Taiwanese.
On Wednesday last week, the Rossiyskaya Gazeta published an article by Chinese President Xi Jinping (習近平) asserting the People’s Republic of China’s (PRC) territorial claim over Taiwan effective 1945, predicated upon instruments such as the 1943 Cairo Declaration and the 1945 Potsdam Proclamation. The article further contended that this de jure and de facto status was subsequently reaffirmed by UN General Assembly Resolution 2758 of 1971. The Ministry of Foreign Affairs promptly issued a statement categorically repudiating these assertions. In addition to the reasons put forward by the ministry, I believe that China’s assertions are open to questions in international
The Legislative Yuan passed an amendment on Friday last week to add four national holidays and make Workers’ Day a national holiday for all sectors — a move referred to as “four plus one.” The Chinese Nationalist Party (KMT) and the Taiwan People’s Party (TPP), who used their combined legislative majority to push the bill through its third reading, claim the holidays were chosen based on their inherent significance and social relevance. However, in passing the amendment, they have stuck to the traditional mindset of taking a holiday just for the sake of it, failing to make good use of
As strategic tensions escalate across the vast Indo-Pacific region, Taiwan has emerged as more than a potential flashpoint. It is the fulcrum upon which the credibility of the evolving American-led strategy of integrated deterrence now rests. How the US and regional powers like Japan respond to Taiwan’s defense, and how credible the deterrent against Chinese aggression proves to be, will profoundly shape the Indo-Pacific security architecture for years to come. A successful defense of Taiwan through strengthened deterrence in the Indo-Pacific would enhance the credibility of the US-led alliance system and underpin America’s global preeminence, while a failure of integrated deterrence would
