Large Volume Holding Reports (EDINET)(/edinet/large-volume-shareholders)

GET /v2/edinet/large-volume-shareholders

Overview

Retrieves the issuer and filer information disclosed in Large Volume Holding Reports, their Change Reports, and Amendment Reports.

Attention

Available for filings submitted on or after July 1, 2021. Target documents are Large Volume Holding Reports and Change Reports (document type code 350) and Amendment Reports (document type code 360).
The method for calculating the number of share certificates held and the holding ratio may change due to regulatory revisions. Because such a change can give rise to a filing obligation, please note that a filing, or a change in the reported values, does not necessarily involve a purchase or sale. ※ Effective May 1, 2026, amendments to the Large Shareholding Reporting Rule changed its scope, the calculation of shareholding ratios, the definition of joint holders, and the reporting forms. Accordingly, changes in the number of shares held, shareholding ratios, or holder composition around this date may occur without any acquisition or disposal of shares. In particular, for reports with a reporting obligation date of May 1, 2026, do not identify trading activity solely from differences from the previous report. Also review the acquisitions and disposals during the preceding 60 days, the reason for the change, and the original report where necessary. The applicable rules and reporting forms are determined by the date on which the reporting obligation arose, rather than the filing date. For further information, please refer to the materials published by the Financial Services Agency.
Available on the Standard plan or higher (Free / Light plans cannot use this API). Historical range: Standard up to 10 years, Premium up to 20 years.
Large volume holding data is available via API only. File download (CSV / Bulk) is not supported.

We do not provide the date and time when each data item became available on J-Quants. For update frequency and approximate update times, see Update Timing of Provided Data.
Questions we have received about data specifications are also answered in the FAQ (Data & Specs).

Data correction policy

An amendment report does not replace the original document; it is delivered as a separate document with its own document ID (DocId). The original document is also retained, so DocId lets you identify which document a value is based on.
The record of an amendment report contains the document ID of the original document (ParDocId).

In this service, we may add or overwrite data due to data deficiencies or omissions. In such cases, the correction history is recorded on Data Correction History and Known issues, so please refer to it.
Note: In these cases, neither the correction history nor pre-correction data is provided via the API, CSV, or other means.
