🛎️ Anyone who has spent time in Japan remembers the service: the bow at the convenience store, the apology broadcast when a train runs ninety seconds late, the gift-wrapping that borders on origami. It is one of the country's quiet marvels. It also carries a cost that Japan is only now naming out loud. From October 2026, every employer in the country, from a national supermarket chain down to a one-person family shop, will be legally required to protect staff from abusive customers. The behavior they are guarding against even has its own word: kasu-hara. Most countries don't have one.

What exactly is "kasu-hara"?

"Kasu-hara" is shorthand for "customer harassment." It covers the shopper who demands a refund or replacement they have no real claim to, who hurls merchandise across the counter, who spits at a clerk, who forces an employee into a dogeza (kneeling on the floor, forehead pressed to the ground in abject apology), or who pins a single worker in a "complaint" for hours on end. Those examples come straight from the guideline the Ministry of Health, Labour and Welfare issued in February 2026.

The scale is hard to wave away. In a 2024 survey of roughly 33,000 retail and service workers by UA Zensen, Japan's largest private-sector union federation, 46.8% said an abusive customer had targeted them in the previous two years. That was actually down from 56.7% in 2020, but it still means nearly one in two people behind a counter. The most common form was verbal abuse, followed by intimidation, repetitive badgering, and being physically detained.

The "customer is a god" misunderstanding

To see why Japan needed a law — and a word — you have to start with a phrase: okyaku-sama wa kami-sama desu, "the customer is a god."

The irony runs deep. The line came from a postwar enka singer named Haruo Minami, and according to his daughter and his official estate he never meant that customers should be obeyed no matter what. By "customer" he meant his audience, and he was talking about himself: he sang as if praying before a deity, emptying his mind to deliver a flawless performance. It was a statement about an artist's discipline, not a buyer's entitlement. Somewhere along the way (helped, some argue, by managers who found "the customer is a god" a handy way to keep staff compliant) it curdled into a license for shoppers to behave however they pleased.

Layered on top is omotenashi, a service culture that treats anticipating and absorbing every customer need as a point of professional pride, and a workplace norm in which the clerk who pushes back against a paying customer is the one who looks unprofessional. The result is a feedback loop the West never wound quite so tight: the customer is told they are sacred, the worker is told never to refuse, and the line between a demanding request and outright abuse quietly disappears.

A duty placed on every employer

The first crack in that arrangement came from Tokyo. In October 2024 the metropolitan government enacted Japan's first anti-kasuhara ordinance, in force from April 2025, which named the problem and asked employers to make an effort to protect their staff.

The national government then went further. In June 2025 the Diet revised the Labor Measures Comprehensive Promotion Act, Japan's central piece of labor-policy legislation, and from October 1, 2026, shielding workers from customer harassment becomes a sochi gimu, a positive duty of care, for every employer with even a single worker.

The law is more limited than it sounds. It does not turn rudeness into a crime, and it does not let companies fine bad customers. Instead it obliges employers to build protections: publish a clear policy that staff will be defended, set up a complaints desk, avoid leaving an employee to face an abuser alone, respond after incidents, and, in the worst cases, issue warnings, refuse service, ban offenders, or call the police. A worker who reports abuse cannot be penalized for it. An employer who ignores the duty faces administrative pressure (guidance, recommendations, and ultimately being named in public) rather than a fine. The ministry's February 2026 guideline also drew the boundaries wide: kasuhara covers not just face-to-face incidents but abuse over social media, and not just consumers but business clients.

Where it hits hardest

The numbers are worst where the work is most personal. A joint survey by UA Zensen and a healthcare-sector labor council, covering about 7,000 medical and care workers, found that 47.6% of caregivers had faced harassment from patients, residents, or their families. Verbal abuse led the list, with being physically shoved or struck close behind, and close to a third reported sexual harassment.

Care work also carries a complication that retail does not. Some of the abuse comes from patients with dementia or psychiatric conditions, and the reflex of "they're ill, what can you do" leaves staff absorbing it in silence. Union leaders warn that if this is allowed to continue in a sector already short of workers, people will simply leave, and the care an aging Japan depends on will get harder and harder to staff.

How the rest of the world handles it

Other countries have the behavior; most of them don't have the word. "Kasu-hara" is a Japanese coinage with no settled English equivalent; English reaches for descriptions like "customer abuse" instead. That linguistic gap is telling in itself: Japan's intense service expectations made the pattern distinct enough to deserve a name.

The remedies diverge, too. Britain went down the punitive route. Under the Crime and Policing Act that became law in 2026, assaulting a retail worker is now a standalone criminal offence in England and Wales, carrying up to six months in prison, with Scotland having had a similar law already. That aims at the offender. Japan's law aims at the employer's duty to shield the worker. Neither is obviously the whole answer, and both run into the same hard question: where does a legitimate complaint end and harassment begin? Draw the line too loosely and you punish a frustrated customer; draw it too tightly and the clerk is back to swallowing whatever comes across the counter.

What Japan is really doing is renegotiating a bargain it struck with itself decades ago — that the person behind the counter owes the person in front of it limitless patience. In your country, where is that line drawn? Is the customer always right, or does the worker get to say "enough"?
