MexicoChecked 18 August 2026
Depends on your industryWork: MediumEnforcement: Waking up
In one paragraph
Mexico's general privacy law does not care where you store data. There is no approved-country list, no standard contract to sign and no permission to ask for. You need the right wording in your privacy notice and, usually, the person's consent. The rules that actually pin data to Mexico live in banking, money-laundering and tax law, not in the privacy law.
The catch
The relaxed headline stops the moment you are a bank, a stockbroker, a crowdfunding platform, an insurer or a phone company. Banks need written permission from the banking regulator before any processing happens abroad. Separately, anti-money-laundering law and tax law require many ordinary businesses to keep their records at a Mexican address for ten and five years. Those rules bind companies that have never read a privacy law.
Does this apply to me?
Probably yes, but Mexico is unusually vague about it. The privacy law says only that it applies across Mexican territory. It does not spell out when it reaches a company based abroad. The old rulebook did say the law caught a foreign company that used equipment or systems located in Mexico, and let that company appoint a local representative instead of opening an office. That old rulebook belonged to a law that was scrapped in March 2025, so its status today is genuinely unclear. There is no revenue or headcount threshold to fall below.Medium confidence
Can the data leave the country?
Under the general privacy law, yes, and with very little paperwork. Mexico has no list of approved countries and no list of banned ones. Sending data to a company abroad is treated exactly like sending it to a company down the road: say so in your privacy notice, get the person's consent unless one of seven exceptions applies, and pass the privacy notice on to whoever receives the data. Handing data to your own supplier who only follows your instructions is not even counted as a transfer. Five sectors override this, and in three of them the override is severe.High confidence
What do I have to do to send it abroad?
Nothing needs approval and no list exists in either direction. The model is simply unrestricted: any destination is allowed. What you need is a privacy notice that names the transfer and carries a clause where the person accepts or refuses it, plus that person's consent unless one of seven legal exceptions covers you. Because there is no list to populate, the government cannot make this stricter by adding a country. It would take a new law or a new regulation.High confidence
Who enforces this — and are they actually working?
Mexico abolished its independent privacy regulator. The National Institute for Transparency, Access to Information and Data Protection was wound up in March 2025 and its staff, files and cases were moved into a government ministry, the Anti-Corruption and Good Government Ministry. So the referee is now part of the government rather than independent of it. The ministry is staffed, but the law says the detailed procedure for complaints, inspections and fines will be set out in a regulation, and that regulation still has not been published. Financial regulators, by contrast, are visibly active and update their rulebooks almost monthly.Medium confidence
How long must I keep it, and when must I delete it?
There is no single retention period. The privacy law says delete data once it is no longer needed, after a blocking period equal to the time limit for suing over the relationship. One hard ceiling is written into the law: information about someone breaking a contract must be erased six years after the default. The floors are longer and come from other laws. Tax records must be kept five years and their supporting documents must be available at your Mexican tax address. Anti-money-laundering records must be kept ten years at an address you register with the Finance Ministry. Phone companies keep call and location records for two years. Where a floor and a ceiling clash, the floor wins, because the privacy law lets you keep data to meet a legal duty.High confidence
What happens when something goes wrong?
There are at least three clocks and they do not agree. Under the general privacy law you must tell the affected people immediately if a breach significantly harms their money or their reputation, and there is no duty to tell the regulator at all. Banks face a much tighter set: tell the banking regulator immediately, tell affected customers within forty-eight hours, file a full report within five working days, and send a remediation plan within fifteen working days of the incident ending. Phone companies must hand requested records to the authorities within twenty-four hours and keep a team available every hour of every day. Mexico has no general cyber-incident reporting law that catches everyone.High confidence
What's the trap?
Five things catch people out. Every private business in Mexico is now legally required to ask customers for their national population ID number. Anti-money-laundering rules force many ordinary businesses to keep ten years of records at a Mexican address, which quietly rules out a pure foreign cloud setup. Mishandling data can put a person in prison, not just cost a company money. Banks must get written permission before any processing happens abroad, and that includes routine cloud hosting. And the rulebook the privacy law keeps pointing at does not exist.High confidence
What's about to change?
The biggest thing coming is a regulation that is already overdue. The privacy law repeatedly says a rulebook will set the deadlines for complaints, inspections and fines, and the government missed its own June 2025 deadline to publish it. When it lands it could change how enforcement works overnight, with no consultation. Health law was changed in January 2026 to put telehealth on a statutory footing, and the biometric national ID is still being rolled out. The dangerous powers are the ones the government already holds rather than any bill in parliament.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
