JapanChecked 18 August 2026
Yes, with paperworkWork: MediumEnforcement: Active
In one paragraph
Japan lets personal data leave the country, but you need paperwork. Only Europe and the United Kingdom are pre-approved. For anywhere else you either sign a contract that binds the recipient to Japanese-standard protection, or you get the person's consent after telling them which country the data goes to. There is no general rule forcing data to stay in Japan.
The catch
Two things break the calm headline. If you sell to the Japanese government, the data must physically sit in Japanese data centres. And if you run a website, an app or any online service used from Japan, the telecoms law reaches you even with no office here, requires a representative in Japan, and makes leaking a communication a criminal offence rather than a fine.
Does this apply to me?
Yes. Japan's privacy law reaches a foreign company with no office and no staff in Japan, as long as it handles the personal information of people in Japan while supplying them goods or services. There is no size, revenue or headcount threshold to fall below. Unlike Europe, the privacy law does not make you appoint a representative in Japan — but the telecoms law does, if your service counts as a telecommunications service.High confidence
Can the data leave the country?
Yes, with paperwork. Japan's general rating is conditional: personal data may go abroad once you have one of three things in place. There is no across-the-board law keeping data in Japan, and no financial, insurance, securities or health localisation rule of the kind India or China have — we searched for one and did not find it. The real wall is government work: anything running on the national Government Cloud must sit in data centres inside Japan.High confidence
What do I have to do to send it abroad?
The model is an allowlist, and the list has exactly two entries: the European Union and the United Kingdom. Send data there and it is treated almost like a domestic transfer. For every other destination you need one of two things instead. Either the recipient is contractually bound to protect the data to Japanese standards and you keep checking that it does, or you get the person's consent after first telling them the destination country, what its privacy law is like, and what the recipient will do to protect the data.High confidence
Who enforces this — and are they actually working?
The Personal Information Protection Commission, and it is genuinely working. It has a chair, eight commissioners and a staff ceiling of 231 people. In the year to March 2025 it handled just over 19,000 breach reports, gave 395 pieces of formal guidance and made one recommendation. In the first six months of the following year it sharpened up: two recommendations and its first emergency order, against a company misusing personal information. What it cannot do yet is fine you — Japan has no administrative money penalty for privacy breaches until the 2026 amendment starts.High confidence
How long must I keep it, and when must I delete it?
The floor is firm and the ceiling is soft. Tax law makes you keep books and records for seven years, stretching to ten if you carry a loss forward. Company accounting books run ten years. Against that, the privacy law only asks you to try to delete personal data once you no longer need it — it is a best-efforts duty, not a hard deadline. So when the two collide, the keep-it rule wins in practice.Medium confidence
What happens when something goes wrong?
Count three clocks. For a personal data breach you file a first report to the privacy regulator within three to five days of finding out, and a full report within 30 days — 60 days if someone did it on purpose. You must also tell the people affected. Critical infrastructure operators have a separate cyber incident duty with a report to the government within 30 days. Telecoms operators report leaks of communications to the communications ministry on their own timetable.High confidence
What's the trap?
Five. (1) Putting data on a foreign server is often not a 'transfer' at all — if the provider is contractually barred from touching it — but you then have to work out that country's privacy law and publish the country's name to your users. Most people miss this. (2) The privacy law has no fines: the sanctions are criminal, and a company can be fined about $650,000 for a staff member stealing a customer database. (3) Leaking a communication is a crime punishable with prison, and telecoms staff face a longer term than outsiders. (4) The telecoms rules catch ordinary websites and apps, not just phone companies, and reach foreign operators with no office in Japan. (5) Consent to send data 'overseas' is not valid — you have to name the country.High confidence
What's about to change?
The big one has already passed. On 17 July 2026 Japan published a large amendment to its privacy law. It introduces the country's first money penalty for privacy breaches, sets 16 as the age below which a guardian must be involved, adds rules for face and other biometric data, and raises the criminal penalties. It is not in force yet: the government has up to two years to switch it on by order, and no date has been announced. The other thing to watch is the new cyber defence law, which is being switched on in stages through 2027.High confidence

United StatesChecked 18 August 2026
Depends on your industryWork: HighEnforcement: Active
In one paragraph
In general the United States lets data go anywhere. There is no national privacy law and no permit is needed to move data abroad. Two things bite hard. Six countries are effectively off limits for large amounts of sensitive data, with prison sentences attached. And anything connected to government work must physically stay on American soil.
The catch
The open headline stops the moment you touch one of six areas: government contracting, police records, federal tax records, defence technical data, telecom licences, and bulk sensitive data flowing to China, Russia, Iran, North Korea, Cuba or Venezuela. Also note that the rule that actually binds you is almost always a state law or an industry regulator's rule, not a national privacy act. There isn't one.
Does this apply to me?
Yes. American rules reach a foreign company with no office in the country. California's privacy law applies to any for-profit business that 'does business in California' and crosses one of three thresholds, and physical presence is not one of them. The children's rule covers foreign websites aimed at American children. No state and no federal law requires you to appoint a local representative — a real difference from Europe.High confidence
Can the data leave the country?
It depends entirely on your industry, so the single national answer is misleading. For ordinary consumer or employee data, yes — send it anywhere, no paperwork. But six sectors have hard walls. Government contracting, police data, federal tax data and defence work require the data to physically stay in the United States. Telecom licences restrict which foreign staff may even look at records. And for anyone, sending large volumes of sensitive data to six named countries is now a crime.High confidence
What do I have to do to send it abroad?
For ordinary data, nothing. No standard contract, no government approval, no destination approval list. The model is a blocklist and it is now populated: six countries are named. Before you move large volumes of sensitive data, your only real job is to work out whether a country of concern, or a company or person they control, could end up with access — including through a vendor, an investor or an employee.High confidence
Who enforces this — and are they actually working?
Nobody, and everybody. There is no national privacy regulator. Instead the consumer protection regulator, the health department, the securities regulator, the communications regulator, the Justice Department, all fifty state attorneys general and one dedicated state privacy agency each enforce a slice. Almost all of them are visibly working right now. The one exception is the new national data transfer programme: it is staffed and issuing guidance but has published no enforcement action yet.High confidence
How long must I keep it, and when must I delete it?
There is a strong floor and a weak but growing ceiling. Investment firms must keep some books for six years and most others for three, with the first two years easy to reach. Health providers keep their paperwork for six years. In the other direction, state privacy laws now force you to publish how long you keep each type of data and to stop keeping it longer than you said, and since April 2026 children's data may no longer be kept indefinitely. Where a keep-it rule and a delete-it rule collide, the keep-it rule wins: every state law carves out data you are required by law to retain.High confidence
What happens when something goes wrong?
Count the clocks — there are at least seven, and they disagree. New York financial firms: 72 hours to the state regulator, and only 24 hours to report paying a ransom. Telecom carriers: seven working days to the police agencies and the communications regulator, and you may not warn customers until seven working days after that. Investment and finance firms: 30 days to affected customers. Health organisations: 60 days. Texas and many other states: 30 days to the state attorney general. Listed companies: four working days to disclose a material incident. The overlap, not any single deadline, is what people fail.High confidence
What's the trap?
Five that cost people their weekend. One: the national data transfer programme carries prison — up to twenty years for a deliberate breach. Two: Illinois lets individuals sue over fingerprints and face scans with fixed damages per person, no proof of harm needed, and that is where the largest privacy payouts happen. Three: the children's rule uses under 13, but several state laws use under 18, so a single age gate will not do. Four: government work means American soil, and police data allows only the United States, its territories, tribal lands and Canada. Five: a rule can be printed in the law book and still be unenforceable, because a court has blocked it.High confidence
What's about to change?
Four things in the next twelve months. The national critical infrastructure reporting rule should be finalised in late 2026, which will switch on a 72-hour incident clock and a 24-hour ransom-payment clock for a very wide range of businesses. California's rules on automated decision-making bite on 1 January 2027. The open banking rule is being rewritten after a court blocked it. And a federal privacy bill is moving in Congress, but it is only a bill and binds nobody.High confidence
