Hong Kong SARChecked 18 August 2026
Depends on your industryWork: MediumEnforcement: Active
In one paragraph
Hong Kong's privacy law contains a cross-border transfer ban that has never been switched on. It was written in 1995 and, thirty years later, still has no start date. So under the general law you can send personal data anywhere with no paperwork at all. The privacy regulator is busy and prosecutes people, but it cannot fine you directly.
The catch
The free-for-all stops at three doors. Licensed securities and futures firms need written permission from the markets regulator before their records live only on servers outside Hong Kong. Government departments are told not to put sensitive or personal information on public cloud at all. And data coming the other way, from mainland China into Hong Kong, is tightly controlled by mainland law, not by Hong Kong law - that is the wall most companies actually hit.
Does this apply to me?
Yes, it can reach you with no office in Hong Kong. The privacy law bites on whoever controls the collection, holding, use or processing of personal data in or from Hong Kong, so a foreign company running a Hong Kong-facing service is caught. There is no revenue or headcount threshold to fall below, no register to join, and no requirement to appoint a local representative. The anti-doxxing powers go further still: the regulator can order an overseas platform to take material down.High confidence
Can the data leave the country?
Under the general privacy law, yes - freely, with nothing to sign. The one section that would have restricted transfers abroad was written into the law in 1995 and has never been brought into operation, so today there is no legal control on personal data leaving Hong Kong. Industry rules are where the real limits sit, and there are fewer of them than people expect: the securities regulator is the main one, and government departments have their own restriction.High confidence
What do I have to do to send it abroad?
Nothing. There is no approval to seek, no standard contract to sign and no government list to check before personal data leaves Hong Kong. The model on paper is an allowlist - the regulator would publish a list of approved destinations - but because the section was never switched on, that list has never been issued and is empty. The regulator does publish a voluntary guide and encourages firms to build the safeguards now, but that is advice, not law.High confidence
Who enforces this — and are they actually working?
The Privacy Commissioner for Personal Data, and it is genuinely busy. By the end of December 2025 it had issued 2,104 orders to 57 online platforms to take down 33,743 doxxing messages, opened 519 criminal investigations and arrested 81 people. But there is a catch that changes the risk picture completely: the Commissioner cannot impose a fine for breaking the privacy principles. It serves a notice telling you to fix the problem, and only ignoring that notice is a crime.High confidence
How long must I keep it, and when must I delete it?
There is a hard ceiling and almost no floor in the privacy law itself. You must erase personal data once it is no longer needed for the purpose you collected it for, and failing to do so is a criminal offence carrying a fine of up to HK$10,000 (about $1,300). The privacy law sets no minimum keeping periods; those come from tax, company and anti-money-laundering law instead. Where the two pull against each other, the specific keeping duty in the other law wins, and you delete once it expires.Medium confidence
What happens when something goes wrong?
For a normal data breach there is no deadline, because there is no duty. Telling the Privacy Commissioner about a breach is voluntary in Hong Kong - the regulator asks you to do it as good practice and gives you a form, but no law compels it. That is unusual and it is changing: since 1 January 2026 operators of designated critical infrastructure must report computer-system security incidents, so those firms now have a real clock while everyone else has none.High confidence
What's the trap?
Five things that catch people out. First, marketing mistakes are crimes here, not fines - using someone's data for direct marketing without the right consent can mean five years in prison. Second, the regulator cannot fine you, so people assume the risk is low and miss the criminal exposure entirely. Third, Hong Kong sets no age at which a child can consent, so there is no simple number to code into a sign-up flow. Fourth, licensed securities firms need written permission before their records live only on overseas servers, and two named people who live in Hong Kong must be able to unlock them. Fifth, the dormant transfer section, if ever switched on, would also catch data moving between two foreign countries when a Hong Kong company controls it.Medium confidence
What's about to change?
Nothing is scheduled to land in the next twelve months that we could confirm. The critical infrastructure security law already started on 1 January 2026, and the government's guideline for generative artificial intelligence was revised in December 2025. The thing to watch is not a new bill. It is a switch the government has held for thirty years: the cross-border transfer section can be brought into force by a simple commencement notice, with no consultation and no new vote.Medium 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
