Follow the filer. Japan's 5% filings and tender offers, in English, minutes after they are filed.
Free 24 hours after the filing goes public. Minutes after, if you pay.
Fact-only English alerts for Japan's large shareholding (5%) and tender offer (TOB) filings, with filer-level following, to Telegram or email.
There is a free tier, and it is not a trial. It carries every filing this wire covers, with the same facts, the same wording and the same links — 24 hours after the document becomes public on EDINET. No card, no charge.
Paying buys time and capacity, not better facts. Individual $29 per month and Pro $99 per month (planned prices) remove the 24-hour wait and let you narrow the wire to the filers you follow.
Not open yet. Get early access and we will email you as soon as the free tier opens.
A 5% report is filed by the investor, not by the company — so feeds built around company news have no natural place for it. Here you follow the filer itself: add a fund to your list once, and when it reports or moves a 5% position in any listed company in Japan, the facts reach your Telegram or inbox. Tender offer (TOB) documents and selected extraordinary reports arrive the same way — fact-only alerts from EDINET, Japan's official disclosure system.
Every alert carries the filing's facts and a link to the original document. Nothing is added: no scores, no commentary, no forecasts.
Three real alerts, generated from filings made on 25 August 2026, are printed further down this page exactly as they came out.

One email address. No card, no checkout, nothing to pay.

Filed in Tokyo. In Japanese. While you sleep.
Japan's statutory ownership disclosures are public, free, and detailed. They are also written in dense legal Japanese and filed during Tokyo business hours — the middle of the night in New York, dawn in London.
Large shareholding reports have a second quirk: they are filed by the investor, not by the company. A workflow built around company news and earnings calendars has no natural place for a document the company itself never issues.
English coverage of Japanese filings exists, and some of it is good. But much of it arrives in overnight batches or next-day digests, focuses on earnings and company-level reports, or is priced and built for institutions. A filing can be public for hours — sometimes a day — before the facts reach you in English.
The do-it-yourself route means watching a Japanese-language government system and machine-translating PDFs at 2 a.m. That is not a workflow. That is a second job.
One filing, one alert. Facts only.
Coverage
- Large shareholding (5%) reports — new reports, change reports, and corrections, filed when a holder crosses 5% of a listed company and when the position later changes by one percentage point or more
- Tender offer (TOB) documents — offer registration statements, the target company's position statements, amendments, and withdrawal notices
- Selected extraordinary reports — events such as changes of major shareholders or representative directors
"Selected" there means a fixed list of event types, decided in advance. It does not mean we go through the day's filings and pick. We do not choose which companies appear in this wire, and we do not choose which filers appear in it. Everything that matches the list goes out.
Follow the filer, not just the company
Add a filer to your list once; when that filer submits a large shareholding report on any listed company, the facts come to you. Follow companies too — you get the covered filings that name them. Follow lists are part of the paid plans; the free tier receives the whole wire instead of a filtered slice of it.
Corrections are part of the product
Filings get corrected and withdrawn. We track filing status and send a correction notice to the same channels, tied to the same document ID, so you can check any alert against the original on EDINET.
A weekly recap
Once a week, a plain list of the week's 5% and TOB filings, one line per filing, in the same fact-only format. No rankings, no trends, no narrative.
Delivery: Telegram and email
Use either or both.
This is a one-way wire
We send filings. We do not comment on them, interpret them, or answer questions about what any of them means, on any tier. The one exchange we do have: if an alert does not match the original document, tell us and we will correct it.
One honest note on timing
Two things we will not pretend away: filings only land on weekdays during Japan's business hours, and a 5% report may legally be filed up to five business days after the position crossed the threshold. We work on the last mile, from filing to your screen. We cannot compress the legal calendar.
These are real alerts generated from filings on 25 August 2026.
Not mock-ups, not dummy names. These three came out of our generator on 25 August 2026, from documents filed that day. They are reproduced here exactly as generated — same wording, same order, same links. Every one of them ends with a link to the original document on EDINET, so you can check our summary against the filing yourself before you decide anything about us.

Notice what the third one does not do. The stated purpose in that filing is a long legal passage, so the alert says so and sends you to the document, instead of paraphrasing a legal statement into something it does not say. If it is not in the filing, it is not in the alert.
Those three alerts are what the free tier sends, word for word. The paid tiers send the same three, without the 24-hour wait.
How quickly, measured
On 25 August 2026 we measured the gap between a document becoming available on EDINET and our system detecting it, across 35 filings: a median of 2 minutes 30 seconds and a maximum of 2 minutes 59 seconds.
That number is detection, not delivery. Formatting and sending an alert takes further seconds on top, and we have not yet measured that under live conditions with subscribers. We will publish delivery times when there are deliveries to measure, rather than quoting a number we have not earned.
That gap is the entire product difference between free and paid. Minutes on one side, a day on the other, and the same words in the message either way.
Where the filings landed
Of the 45 large shareholding reports processed on 25 August 2026, 15 named companies listed on the Standard market and 13 on Growth — 28 of the 45, or 62%. Prime accounted for 13 and TOKYO PRO Market for 4.
Those two segments are also where company-published English is thinnest. In the Tokyo Stock Exchange's survey as of the end of December 2025, 7.9% of Standard-listed companies and 14.1% of Growth-listed companies published timely disclosure materials in English, against 96.8% on Prime.
Two caveats, because the numbers are easy to over-read. This is one day of filings, not a trend — we will keep publishing the counts as they come, including the days that flatter us less. And the two figures measure different things: a shareholding report is filed by the investor, so no company's translation policy applies to it. What the survey describes is the English information environment around these names — the smaller the company, the less of it exists in English.
Free is the default. Pay only for time.
Start free. The free tier carries every filing this wire covers — not a sample of them, not the interesting ones, not the large caps. Every one, in the same format as the alerts printed above, with the same link to the same original document. It arrives 24 hours after the document becomes public on EDINET.
| Free — $0 | Individual — $29/month (planned) | Pro — $99/month (planned) | |
|---|---|---|---|
| Filings covered | All of them | All of them | All of them |
| When it reaches you | 24 hours after the document becomes public on EDINET | As soon as we can after the document becomes public — see the measurement above | Same as Individual |
| Follow list (filers + companies) | None — you receive the whole wire | Up to 10 | Unlimited |
| Delivery destinations | 1 | 1 | 5 (for example, team inboxes plus Telegram channels) |
| Facts, wording, links, corrections | Identical | Identical | Identical |
The three tiers differ in three numbers: how long you wait, how many filers you can follow, and how many destinations we deliver to. The content does not differ at all. Same filings, same wording, same links, same corrections, same weekly recap. There is no premium version of a fact.
Who should stay on free
If you read these filings to keep a record — to know who holds what, to write it up later in the week, to check a position before a meeting — then a one-day-old fact is the same fact. The free tier is the whole product for you. It does not expire, it does not ask for a card, and we would rather you sit on it for a year than pay us for a delay you never feel. Plenty of people should never upgrade, and we would rather say that here than let you find it out after a charge.
Who should pay
If a filing has stopped being useful to you by the time it is a day old — if you trade around these disclosures, cover them for readers, or answer to someone who saw it first — then the wait is the cost, and removing it is what the paid tiers sell. On the day we measured, that difference was minutes against a day. The follow list is the second half: on a 45-filing day, most of them are not about your names.
Prices are shown in USD. The $29 and $99 figures are planned prices for launch, not a live offer — nothing on this page can be bought and no payment details are collected here. If they change before launch, people on the early access list hear it from us while there is still nothing to pay.
There are broader and cheaper English services covering Japanese filings. We would rather you compare before you decide than feel cornered later — see "Are there alternatives?" in the FAQ.
Not open yet. Here is exactly what exists.
What exists today. The alert format is fixed. The generator runs against live EDINET filings — the three alerts above came out of it on 25 August 2026, along with 42 others the same day. Detection speed has been measured once, on real filings, and the figures are printed above.
What does not exist yet. Delivery to subscribers, follow-list management, and billing are not built. Nothing has been sent to anyone outside our own systems.
Why you cannot use it today, free or paid. We are completing legal and compliance checks before we take any money. The same checks gate the free tier, because a free alert and a paid alert are the same document leaving the same system — we would rather open once, late, than open twice.
What happens next. We will email you as soon as the free tier opens. If we later start charging for the paid tiers, you will hear that separately and in advance — not after, and not on the same day. If we decide not to open at all, people on the list will be told that too, in plain words.
We are not announcing a date we cannot yet stand behind. Early access is how you find out first, and it costs you an email address.
Questions you should ask
Do you tell me what to buy or sell?
No. We report what was filed — names, numbers, dates, and the purpose as stated in the document — and we link to the original. We do not interpret filings, score them, or express views on any security. The formal wording, which also appears in our terms and in every alert footer:
"This service provides English-language factual summaries and notifications of statutory disclosure documents (large shareholding reports, tender offer filings, and selected extraordinary reports) filed with EDINET, the electronic disclosure system operated by the Financial Services Agency of Japan. It is a news/translation service only. It does not provide investment advice or recommendations, does not express any opinion on the value or price outlook of any security, and is not registered as a financial instruments business operator under the Financial Instruments and Exchange Act of Japan. Summaries are edited by Hayato Miyauchi and are not official translations. Source: EDINET (https://disclosure2.edinet-fsa.go.jp/), used under the Public Data License 1.0 (PDL1.0). Always refer to the original filing (linked in each notice). Investment decisions are your own responsibility."
Is the free tier a trial?
No. It has no expiry date, no card field, and no reduced version of the content. You get every filing this wire covers, with the same wording and the same links as the paid tiers, 24 hours after the document becomes public on EDINET. If that suits you, stay on it.
Then what am I paying for?
Two things, and neither of them is information. Time: the paid tiers drop the 24-hour wait and send the alert as soon as we can after the filing becomes public. Capacity: a follow list, so a day's filings arrive narrowed to the filers and companies you chose, and more than one delivery destination on Pro.
What does getting early access commit me to?
Nothing. It is an email address, not an order. There is no card field, no checkout, and no charge — now or later — without you actively choosing a paid tier once one exists.
What will you send me?
One short note when the free tier opens. If we later start charging for the paid tiers, a separate note before that happens. Nothing else, and one click unsubscribes.
When does it open, and what will it cost?
We are not putting a date on this page that we cannot stand behind. The free tier will cost nothing. Planned pricing for the paid tiers is $29 per month for Individual and $99 per month for Pro — planned, because nothing is being sold today. People on the early access list hear about the date and the final prices before either becomes real.
Are those alerts really real?
Yes, and you do not have to take our word for it. Each of the three carries its document ID and a direct link to the original filing on EDINET. Open the document and compare it with the alert. That check is the whole point of printing them here.
Where does the data come from?
From EDINET, the official electronic disclosure system operated by Japan's Financial Services Agency, where these documents are filed and made public by law. Public data is used under Japan's Public Data License 1.0, with source attribution on every alert. Every alert carries the document ID and a direct link to the original filing, so you can verify every alert against the original. Stakewire Japan is independently operated. It is not endorsed by, and does not act on behalf of, the FSA, any exchange, or any issuer, and our summaries are not official translations.
Will you answer my questions about a filing?
No, on any tier. This is a one-way wire: filings go out, and that is the whole of it. We do not explain what a filing means, take requests to look into a company, or hold views on the names in it. The single exception is accuracy — if an alert does not match the original document, tell us and the correction goes out.
How will alerts arrive?
By Telegram and by email — either or both. Free and Individual deliver to one destination; Pro to up to five (team inboxes, multiple Telegram channels). If you do not use Telegram, email alone works fine.
Who runs this?
Stakewire Japan is operated by Hayato Miyauchi (Japan) — an independent operator based in Japan, working in Japan's time zone with the original Japanese documents. Support: contact@stakewirejapan.com.
Are there alternatives?
Yes, and we would rather say so here than have you find out later. Several services cover Japanese filings in English — some cheaper, some broader, some built for institutions. Most are organized around companies and their reports, and many deliver in daily digests. This wire does one narrow thing instead: 5% and TOB filings, filer-level following, fact-only alerts, to Telegram or email. If you want broad coverage or commentary, another service will fit you better. If you want this narrow thing done properly, start with the free tier and judge it against the documents.
What about corrections and withdrawals?
Filings get amended, corrected, and sometimes withdrawn. We track status and send a correction notice to the same channels, referencing the same document ID, on every tier. If we get something wrong, the correction goes out the same way the original did — not buried on a status page.
Who can sign up?
Customers residing outside Japan. That applies to the free tier exactly as it applies to the paid ones. The service is English-only and is not offered to residents of Japan.
Why is the content identical on every tier?
Because the difference between tiers should be time and capacity, not information. Everyone on a tier gets the same facts in the same words; nobody gets a better version of what a document says.
Can my fund or team use this?
That is what Pro is for: the same alerts, unlimited follows, delivered to up to 5 destinations — team inboxes, shared Telegram channels. If your operations people need paperwork beyond the standard terms, tell us when you get early access and we will take it up before launch.
