United KingdomChecked 18 August 2026
Yes, with paperworkWork: HighEnforcement: Active
- In one paragraph
- Data can leave the United Kingdom, but you need the right paperwork first. Sending it to Europe or to about fifteen other approved places needs nothing extra. Anywhere else needs a government-published contract and a risk check. No general law forces data to stay in Britain. The privacy regulator is busy and its fines are getting bigger.
- The catch
- The easy headline stops being true in three places. Telecoms operators must keep backup copies of key network information inside the United Kingdom. National Health Service patient records may only be sent to countries the United Kingdom has formally approved, which rules out the standard contract route. And government material classified SECRET or above cannot sit in public cloud at all. Everyone else can store data abroad with the right contract in place.
- Does this apply to me?
- Yes. British privacy law reaches a company anywhere in the world if it deliberately offers goods or services to people in the United Kingdom, or watches what they do online. There is no size or revenue floor to hide under. If you are caught and have no British office, you generally have to name a representative in the United Kingdom, unless you are a public body or your processing is rare and low risk.High confidence
- Can the data leave the country?
- Yes, with paperwork. The United Kingdom has no general law forcing data to stay in the country. Send it to the European Economic Area or another approved country and you need nothing extra; send it anywhere else and you need an approved contract plus a written risk assessment. Three industries are stricter: telecoms, the health service and classified government work. Banking, payments, insurance, securities, education, online gambling and mapping have no location rule that we could find.High confidence
- What do I have to do to send it abroad?
- The model is an approved-list one. If the destination is on the government's approved list you may send data with no extra paperwork. If it is not, you must sign the government's own contract template and run a risk assessment first. The list is well populated: the whole European Economic Area plus Andorra, Argentina, the Faroe Islands, Gibraltar, Guernsey, the Isle of Man, Israel, Jersey, New Zealand, South Korea, Switzerland and Uruguay, with partial cover for Canada, Japan and the United States.High confidence
- Who enforces this — and are they actually working?
- The Information Commissioner's Office, and it is very much working. It fined Capita fourteen million pounds (about $18 million) in October 2025, Reddit £14.47 million (about $18.5 million) in February 2026, and the owner of Imgur in the same month, and it issues smaller marketing fines almost monthly. Watch a quirk: a replacement body called the Information Commission legally exists but had no staff and did no work in its first financial year, so the old office is still the one that acts.High confidence
- How long must I keep it, and when must I delete it?
- There is no single deletion deadline. The rule is that you keep personal data only as long as you actually need it, and you must be able to explain the period you chose. Pulling the other way are minimum keeping periods: company and tax records for six years, telecoms connection records for up to twelve months if the government serves a notice, and telecoms security data for thirteen months. Where a minimum and a maximum clash, the legal duty to keep wins and you keep the data.High confidence
- What happens when something goes wrong?
- Count at least three clocks. Any organisation has 72 hours to tell the privacy regulator about a personal data breach, and must tell the affected people if the risk to them is high. Telecoms and internet providers also have 72 hours under the electronic communications rules — that used to be 24 hours and quietly changed on 20 August 2025. Operators of essential services such as water, energy and transport have their own 72-hour clock to their own regulator.High confidence
- What's the trap?
- Five. (1) A child can consent at 13 here, not 16 — but the children's design code covers everyone under 18, and the regulator fined Reddit £14.47 million (about $18.5 million) for weak age checks. (2) Telecoms firms must keep some backup data physically in Britain. (3) Health service data can only go to approved countries, so the standard contract does not help you. (4) Misusing personal data can be a crime, not just a fine. (5) The government can secretly order a company to weaken its security, and Apple is fighting one of those orders right now.Medium confidence
- What's about to change?
- Two things to watch in the next twelve months. A cyber security bill is going through Parliament and will widen incident reporting to data centres and managed service suppliers — it is not law yet, so do not plan as if it were. And the privacy regulator is due to be replaced by a new body called the Information Commission, but only once ministers lay the paperwork, which had not happened by mid-2026. The regulator is also writing a statutory code on artificial intelligence.High confidence

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
