# Japan tender offer process

## Overview

Japan TOB analysis is a disclosure-control workflow: tender offer trigger, public notice, tender offer statement, target company opinion, amendments, EDINET statutory filing, TDnet timely disclosure, large-shareholding reports, settlement, and squeeze-out / delisting route. It belongs in [[finance/INDEX|finance]] because it is a public-company control-transaction process, not only a trading rule.

For acquisitions occurring on or after **May 1, 2026**, the amended regime's **30% rule** replaces the former one-third control threshold and extends that control-threshold rule to on-market transactions. The separate off-market 5% rule and statutory exemptions still require transaction-specific analysis; this page does not treat every purchase above 5% as a mandatory TOB.

## Process Map

Source: the table follows the FSA's [post-May 1, 2026 tender-offer rules, forms, guidelines, and Q&A](https://www.fsa.go.jp/news/r7/shouken/20250704/20250704.html) and [JPX TDnet](https://www.jpx.co.jp/english/equities/listing/disclosure/tdnet/index.html); filed notices control for each offer.

| Stage | Main artifact | Public relevance |
|---|---|---|
| Deal planning | Offer structure, financing, regulatory approvals, conditions. | Determines whether TOB is mandatory / voluntary and whether squeeze-out is feasible. |
| Trigger analysis | FIEA tender-offer rules and shareholding thresholds. | Outside-market acquisition and ownership thresholds can require a TOB route. |
| Public announcement | Tender offer public notice and press release. | Starts the public process and market reaction. |
| Tender offer statement | Statutory disclosure via EDINET / regulator route. | Core document for price, period, purpose, funding, conditions, and post-TOB policy. |
| Target response | Position statement / support, neutrality, opposition, or board position. | Central to minority-shareholder analysis. |
| Amendments | Correction / amendment filings and changes to terms. | Offer price, period, cap / floor, approvals, and conditions can change. |
| TDnet disclosure | Timely disclosure by listed company. | JPX route for prompt public dissemination and legal publication support. |
| Settlement / squeeze-out | Purchase settlement, delisting, share consolidation, demand for sale, or merger route. | Determines final control and minority-exit mechanics. |

## Large-Shareholding Overlay

Large-shareholding reports are not the same as TOB documents. They answer "who owns / controls a large block?" rather than "what is the offer process?"

Source: the table distinguishes the FSA's [large-shareholding filing route](https://www.fsa.go.jp/common/shinsei/tairyohoyu/index.html) from the [post-May 1, 2026 tender-offer regime](https://www.fsa.go.jp/news/r7/shouken/20250704/20250704.html) and [JPX TDnet](https://www.jpx.co.jp/english/equities/listing/disclosure/tdnet/index.html).

| Report route | Typical use |
|---|---|
| Large Shareholding Report | Initial block ownership / joint-holder disclosure around major shareholding. |
| Change Report | Later increase / decrease or material change. |
| TOB filing | Offer terms, purchase plan, funding, purpose, and tender process. |
| TDnet | Timely public dissemination by the listed company or target. |

Read large-shareholding reports together with [[finance/cross-border-m-a-japan|M&A context]] and [[securities/tokyo-stock-exchange|TSE listing / disclosure route]] before making control conclusions.

## What To Extract

Source: the table is a retrieval checklist keyed to the FSA's [tender-offer disclosure regime](https://www.fsa.go.jp/news/r7/shouken/20250704/20250704.html); only the actual public notice, tender-offer statement, amendments, and target response establish a transaction's terms.

| Field | Why |
|---|---|
| Offeror and target | Legal entity and group route. |
| Offer price and premium | Valuation and minority-shareholder fairness. |
| Offer period | Market-timing and competing-bid window. |
| Minimum / maximum purchase quantity | Control intent, squeeze-out feasibility, partial offer risk. |
| Disclosed funding source and supporting documents | Evidence described in the filed documents for the offeror's ability to settle. |
| Conditions / approvals | Antitrust, foreign investment, sector regulation, financing, or shareholder approvals. |
| Target opinion | Board process, special committee, fairness opinion, conflicts. |
| Post-TOB policy | Delisting, integration, strategy, dividend / capital policy. |

## JapanFG Relevance

- [[megabanks/sbi-hd|SBI HD]] / [[regional-banks/sbi-shinsei-bank|SBI Shinsei Bank]] are useful historical anchors for bank-control and public TOB analysis.
- [[megabanks/sony-fg|Sony FG]], [[payment-firms/wealthnavi|WealthNavi]], and other listed finance / fintech cases may need TOB / squeeze-out reading when control changes.
- Securities firms may act as tender-offer agents, brokers, underwriters, or advisers, but the role of [[securities-firms/smbc-nikko|SMBC Nikko]], [[securities-firms/mufg-mums|MUMSS]], [[securities-firms/nomura-hd|Nomura]], [[securities-firms/daiwa-sg|Daiwa Securities Group]], or any other firm must be confirmed from the filed offer and target documents.
- Check the [[financial-licenses/securities-license-stack|securities license stack]] only for the regulated activity actually performed; the generic label "financial adviser" does not by itself establish a licensing requirement.

## Research Checklist

1. Pull the offeror release, target release, EDINET tender offer statement, and target opinion.
2. Check TDnet / Listed Company Search for timely disclosures and amendments.
3. Check large-shareholding reports for pre-TOB stake, joint holders, and post-announcement changes.
4. Identify minimum / maximum tender quantity, squeeze-out condition, and delisting plan.
5. Check financing source, regulatory approvals, special committee process, and fairness opinion where public.
6. Use exact dates and source documents because TOB terms may be amended.
