Japan’s Secret to Taming the Coronavirus: Peer Pressure

TOKYO — To understand how Japan has fared better than most of the world in containing the dire consequences of the coronavirus pandemic, consider Mika Yanagihara, who went shopping for flowers this past week in central Tokyo. Even when walking outside in temperatures in the mid-90s, she kept the lower half of her face fully covered.

“People will stare at you,” Ms. Yanagihara, 33, said, explaining why she didn’t dare take off her mask. “There is that pressure.”

Japan’s Covid death rate, just one-twelfth of that in the United States, is the lowest among the world’s wealthiest nations. With the world’s third-largest economy and 11th-largest populace, Japan also tops global rankings in vaccination and has consistently had one of the globe’s lowest infection rates.

Although no government authority has ever mandated masks or vaccinations or instituted lockdowns or mass surveillance, Japan’s residents have largely evaded the worst ravages of the virus. Instead, in many ways, Japan let peer pressure do a lot of the work.

Even now, as average daily cases have fallen to just 12 per 100,000 residents — about a third of the average in the United States — a government survey in May found that close to 80 percent of people working in offices or enrolled in school wear masks and about 90 percent do so when using public transit. Movie theaters, sports stadiums and shopping malls continue to request that visitors wear masks, and for the most part, people comply. The term “face pants” has become a buzzword, implying that dropping a mask would be as embarrassing as taking off one’s underwear in public.

Many factors have undoubtedly contributed to Japan’s coronavirus outcomes, including a nationalized health care system and severe border controls that have outlasted those in many other countries.

But social conformity — and a fear of public shaming that is instilled from the youngest ages — has been a key ingredient in Japan’s relative success in Covid prevention, experts say. Unlike in many other countries, Japanese law does not permit the government to order lockdowns or vaccinations. The majority of the population followed each other in heeding guidance from scientific experts who encouraged people to wear masks and avoid situations where they would be in enclosed, unventilated areas with large crowds.

After a slow start, once Japan ramped up the distribution of vaccines, most people followed advisories to get them. Even without mandates, close to 90 percent of all people over 65, the most vulnerable population, have received booster shots, compared with 70 percent of seniors in the United States.

In Japan, “if you tell people to look right, they will all look right,” said Kazunari Onishi, an associate professor of public health at St. Luke’s International University in Tokyo.

“Generally, I think that being influenced by others and not thinking for yourself is a bad thing,” Dr. Onishi added. But during the pandemic, he said, “it was a good thing.”

Unlike in the United States, wearing a mask or getting a vaccine never became ideological litmus tests. Although trust in government has fallen during the pandemic, in a country where the same party has governed for all but four years since 1955, the public put pragmatism over politics in the approach to Covid.

Often, people policed each other or businesses seen to be violating municipal requests to close early or stop serving alcohol during periods designated as states of emergency.

“We got so many reports about shops being open that we started joking about the ‘self restraint police,’” said Yuko Hirai, who works in the emergency response department in Osaka, Japan’s third-largest prefecture. “People were definitely aware that society’s eyes were on them.”

The practice of keeping in line with peers is inculcated in schoolchildren, who wear uniforms in most public schools and are shamed into following institutional expectations. “Just being removed from the group is such a big deal for Japanese kids,” said Naomi Aoki, associate professor of public management at the University of Tokyo. “They always want to belong to a social group and don’t want to feel isolated.”

Children are taught to act for the collective benefit. Students clean classroom floors and school grounds and take turns serving lunch in cafeterias.

Japanese culture also depends on an ethic of public self-restraint that can be marshaled into group action. When Emperor Hirohito was dying in 1988, pop singers postponed weddings and schools canceled festivals.

After the 2011 nuclear disaster in Fukushima led to serious power shortages, the public cut back on electricity use voluntarily. (With temperatures rising in Tokyo this past week, residents are being asked to do so again.)

During the pandemic, politicians tapped “into this collective idea of self-restraint for the public good,” said James Wright, an anthropologist at the Alan Turing Institute in London who has studied Japan’s coronavirus response.

With few legal options for enforcing the guidance, authorities hoped the population would voluntarily comply with pleas to stay home, said Hitoshi Oshitani, a professor of virology at Tohoku University in northeastern Japan and a government adviser.

Despite Japan’s culture of collectivism, Dr. Oshitani was surprised when businesses quickly closed and people refrained from going out. Companies that had never allowed telecommuting sent employees home with laptops. Families canceled visits to older relatives. Close to 200 industry groups representing theaters, professional sports teams, and venues that hosted weddings and funerals issued lengthy protocols for preventing infections.

The public embraced the guidelines, and the overall death rate actually fell below that of the year immediately preceding the coronavirus outbreak.

Those who tried to buck the guidance were subjected to public condemnation. Toshio Date, who operates a venue in Osaka devoted to the board games Go and shogi, initially tried to stay open when the city requested that restaurants, bars and other entertainment businesses shut down.

When local television stations started asking to film the club as an outlier, Mr. Date, 58, got the message and quickly closed. Even after infections settled down in Osaka, which recorded the highest death rate in Japan, and businesses reopened, he said strangers frequently scolded him for hosting too many customers.

Although the public has provided most of the sticks, the government has offered carrots in the form of economic subsidies for businesses.

In 2020, the country paid out over $40.5 billion to more than 4.2 million small- to medium-size companies and individual business owners, according to statistics from the Japanese Ministry of Economy, Trade and Industry.

Larger businesses received “cooperation money” based on their pre-pandemic revenue, as much as 200,000 yen — just under $1,500 — a day.

The incentives were not universally effective. In the first summer of the pandemic, clusters of infections began appearing in nightlife districts in central Tokyo, as visitors to bars and cabarets ignored the experts’ advice.

When businesses flouted guidance on ventilation, masking and alcohol sanitizing, city officials were dispatched to convince them to fall in line. Only as a last resort were businesses fined or cut off from economic subsidies. In Tokyo, according to the city’s Bureau of Industrial and Labor Affairs, between 96 and 98 percent of businesses ultimately agreed to follow the rules.

Experts warn that voluntary compliance is no guarantee of indefinite success.

“The response is like an Othello game,” said Dr. Oshitani, comparing Japan’s coronavirus results to the board game where one move can change a winning outcome to a losing one. “All of a sudden, the most successful countries can become the worst country in the world,” he said.

For now, residents continue to bow to peer pressure.

Kae Kobe, 40, a receptionist at an office in Shibuya, said that because her job is client facing, she always wears her mask at work.

“Everyone around is still wearing it,” she said. “So it’s hard to get rid of it.”
