Terms of use
These terms apply to the JapanStake website, API and MCP server (the service). By creating an account or using an API key you accept them. They take effect on 2026-11-01.
Who runs the service
The service is run by an individual business operator under the name JapanStake. The operator's name and address are given without delay on request, through the contact below. Paid plans are not on sale; the seller will be named here before they are.
The service
JapanStake provides data processed from public filings and other public sources. It is reference information, not investment, legal or tax advice, and not a recommendation about any security. Check important figures against the original source linked from each record.
Not advice
We do not advise on anyone's individual investment decisions and we do not say what to buy, sell or hold. We publish no share prices. Figures, percentiles and sorted lists are arithmetic on the data. If you use the service to give investment advice, to solicit transactions or in any regulated activity, you are responsible for that activity and for any registration it needs.
Accuracy and liability
Filings can contain errors, and our processing can too. The data is provided "as is", without any warranty of accuracy, completeness or availability. To the extent the law allows, we are not liable for losses arising from its use. Nothing here limits liability that the law does not allow to be limited. In particular, where you are a consumer, liability for our intent or gross negligence is not excluded, and any other limit applies only as far as the Consumer Contract Act of Japan permits. Otherwise, our total liability for any claim is limited to the fees you paid us in the 12 months before it arose.
Your account and key
Keep your API key secret. You are responsible for requests made with it. Replace it from the dashboard if it leaks. One person or organisation per account.
Acceptable use
- Stay within your plan's monthly and per-minute limits; do not create extra accounts or keys to get around them.
- Keep the source attribution when you show the data to others, including the EDINET credit as shown on Sources and licences.
- Do not try to identify anyone shown as an individual filer or individual holder, and do not use the data to track, profile or harass a person.
- Do not use the service in breach of the law or of a data source's terms.
Redistribution
"Raw data" means records from the service, in bulk or substantially whole, in any format. You may use the data in your own analysis and products, show it to your own customers in limited amounts as part of something you add value to, and let your AI products cite or display it with attribution. You may not offer raw data as a feed, a database or an API, to your customers or anyone else.
Corrections and stops
Anyone, account holder or not, can ask us to correct a record, or to stop showing information about a person. Use Corrections and removal. We check the request against the source filing and reply by email.
Plans and payment
Every plan is paid; an account without a plan cannot use the API. Billing is not connected yet and nothing is charged. Before any paid plan goes on sale, we will update these terms with how payment, renewal and cancellation work.
Availability
There is no service level commitment. We may suspend the service for maintenance, faults or legal reasons. A data source can change or stop, and a dataset that depends on it can then stop too, without compensation.
Ending
You may stop at any time and ask us to delete your account. We may suspend or end an account that breaches these terms. You may not use the service if you are subject to sanctions that prohibit us from dealing with you.
Rights
Rights in source documents stay with their owners. Rights in our software, site and processing stay with the operator. You receive a right to use the service under these terms, nothing more.
Changes
These terms are standard terms. We may change them where the change benefits users, or is reasonable and fits the purpose of the agreement. We announce the change, its content and its effective date on this page at least 14 days ahead, unless the law or an urgent matter requires less.
Law, courts, language
Japanese law governs these terms. The courts of Japan have jurisdiction, subject to any mandatory right a consumer has to use their own courts. If a translation differs, the English text prevails. If one clause is invalid, the others stand.
