変更報告書
Major Shareholding Notification Classification · 92% confidence The document is a Japanese “変更報告書（大量保有）” – a change report for large shareholding. It details the names of institutional holders, share counts, ownership ratios and regulatory references (法第27条の25), consistent with a Major Shareholding Notification rather than an annual or interim report or insider dealing.

発行登録追補書類（株券､社債券等）
Regulatory Filings Classification · 95% confidence The document is a '発行登録追補書類' (Shelf Registration Supplement) filed by Mizuho Financial Group, Inc. with the Kanto Local Finance Bureau. It details the issuance of specific corporate bonds (第25回 and 第26回). This type of document is a formal regulatory filing required under Japanese financial law for securities offerings.
