Help & Usage

A large shareholding report is a document that investors must submit to Japan's Financial Services Agency (EDINET) when they hold 5% or more of a listed company's shares, or when their ownership ratio changes by 1% or more. These reports allow you to track major investors' stock holdings.

Data is automatically retrieved from EDINET (Electronic Disclosure for Investors' NETwork), operated by Japan's Financial Services Agency. We use official data to provide accurate and reliable information.

You will receive notifications when new large shareholding reports are registered. Notifications are classified into five types: new report, ownership ratio increase, ownership ratio decrease, correction report, and amendment with no ratio change. There is no threshold — any change in ownership ratio is eligible for notification. You can filter notifications to receive only "important reports" related to activist activity or acquisitions. The Premium plan allows individual ON/OFF settings for each notification type.

The Free plan includes report viewing, search, push notifications, rankings (top 5), holding purpose classification, the watch feature (up to 3 registrations in total across issuers and holders), and disclosure document viewing (latest 1). Premium adds holding ratio trend charts, reference average acquisition price, highlighted changes in holding purpose, unlimited watchlist registrations, full ranking access (top 100), granular notification scope (watched targets only) and type settings, and access to past disclosure documents.

The free plan allows up to 3 registrations in total across issuers (stocks) and holders (investors). Premium removes the limit, so you can add as many items of interest as you like.

First, check that push notifications are enabled in the settings screen. Also verify that notifications are permitted for the app in your device settings. If notifications still don't arrive, try restarting the app or contact support.

Tap the "View PDF" button in the report details screen to open the official EDINET PDF file in an external browser. Use this to review formal disclosure content.

The app requires an internet connection. Report data is retrieved from EDINET, so an online environment is necessary to view the latest information.

The app covers large shareholding reports and disclosure documents filed on or after January 1, 2025. Scroll down on the home screen to load past reports, or use the search feature to narrow down to a specific stock or holder.

This feature automatically classifies holding purposes stated in large shareholding reports into categories such as "Significant Proposals" and "Tender Offers," displaying them as badges on report cards. It helps you quickly identify important reports related to activist shareholder proposals and tender offers.

It is the average price per share as of a given report, calculated from the acquisition funds and share count stated in the large shareholding report. It helps you gauge roughly what price level a major investor bought in at. It is a reference value derived by simple calculation from the figures in the report, and does not guarantee the actual purchase price or timing. This is a Premium feature.

When an amendment report's holding purpose differs from the previous report, the app shows a "Changed from previous" badge. This badge is available on the free plan. Premium adds a diff view that highlights the passages that were added or removed. Holding purpose appears as a preview in lists; open the full text via "Read more" to toggle between diff view and normal view.

Yes. You can view tender offer documents such as tender offer notifications and position statements. Issuer profile screens show them alongside disclosure documents like annual securities reports; holder profile screens provide access to tender offer documents. The free plan includes the latest single document; Premium unlocks past documents.

It marks a large shareholding report filed well after its reporting obligation date, so you can spot conspicuously late filings at a glance. You can set the threshold for what counts as delayed to 14, 30, or 90 days in the settings screen.

The holders tab on the issuer profile screen shows joint holders in addition to the representative filer. You can also navigate from a joint holder to the issuers (stocks) they hold. This is useful for tracking, for example, an individual investor involved with several activist funds.

Yes. In the settings screen you can choose whether to show the securities code next to the issuer name, and how to show it (badge, separate line, or hidden). The app interface is in Japanese only; turning off the setting labeled 「(株)等を表示する」 ("Show (株) etc.") omits company designations such as "Co., Ltd." from issuer and holder names. Securities codes also appear on report detail and ownership trend screens.
