Squeeze-Out Procedure in Japan: What to Know About Share Cash-Out Demands

In a squeeze-out, the issue most likely to end up in dispute is not the sequence of the procedure but the basis on which the cash-out price was determined. Deals that fail to document the valuation process in a form a court can later scrutinize tend to come out worse when a price determination petition is filed.

What Is a Squeeze-Out? Its Relationship to the Share Cash-Out Demand

A squeeze-out is an umbrella term for methods used to force minority shareholders out of their equity position for cash consideration. The principal methods are: (i) a share cash-out demand, used when a special controlling shareholder holds at least 90% of the voting rights of all shareholders in the target company (Japan's Companies Act, Article 179 et seq.); (ii) acquisition of shares subject to a wholesale acquisition clause, which requires a special resolution at a general meeting of shareholders; and (iii) a share consolidation (Article 180 et seq.). When a tender offer (TOB) is being followed by an MBO or a move to full subsidiarization, the share cash-out demand is often the method of choice, since it can be executed without convening a shareholders' meeting. This article focuses on the share cash-out demand.

How the Squeeze-Out Procedure Unfolds

The process starts with a TOB or similar transaction that brings the acquirer's holding up to the special-controlling-shareholder threshold — at least 90% of the voting rights of all shareholders (Companies Act, Article 179, paragraph 1). The special controlling shareholder then fixes the amount of cash consideration for the shares to be sold (or the method for calculating it), the acquisition date, and related terms (Article 179-2), and, in a company with a board of directors, obtains board approval (Article 179-3). The target company must notify the selling shareholders of these terms, or make a public announcement, no later than 20 days before the acquisition date (Article 179-4, paragraph 1, item 2). Following that notice — from the 20th day before the acquisition date through the day before it — selling shareholders who meet the statutory requirements may seek an injunction (Article 179-7) or petition the court for a determination of price (Article 179-8, paragraph 1). On the acquisition date itself, the shares transfer to the special controlling shareholder and the consideration is paid out.

How Should the Cash-Out Price Be Determined?

In practice, valuation typically blends the discounted cash flow (DCF) method, the market price method, comparable company analysis, and the net asset method. What matters more than the choice of method, though, is documenting the process behind it — why a particular third-party appraiser was engaged, how the underlying assumptions were set, how the result reconciles with the tender offer price — in a way that can withstand scrutiny after the fact. As the JCOM case below illustrates, what courts ultimately weigh is not the price level itself but the fairness of the process that produced it.

Lessons from the Case Law on Contested Cash-Out Prices

The JCOM case — formally, the price determination proceeding concerning Jupiter Telecommunications Co., Ltd. (JCOM), decided by the Supreme Court of Japan on July 1, 2016 — arose from the squeeze-out that completed Sumitomo Corporation and KDDI's full subsidiarization of JCOM through the acquisition of shares subject to a wholesale acquisition clause. The tender offer price was first announced at ¥110,000 per share and later raised to ¥123,000 per share for execution. The lower courts (the Tokyo District Court and the Tokyo High Court) applied a market-model regression analysis and arrived at ¥130,206 per share, but the Supreme Court overturned that figure. It held that where a tender offer has been conducted through procedures generally recognized as fair, the tender offer price should be treated as the fair price unless there are special circumstances sufficient to find an unexpected change in the underlying premises of the transaction — and on that basis fixed the acquisition price at ¥123,000 per share, matching the tender offer price (BUSINESS LAWYERS, "The JCOM Case," https://www.businesslawyers.jp/articles/346; Plutus Consulting, "Commentary on the JCOM Case," https://www.plutuscon.jp/reports/246). The practical takeaway is that courts give priority to whether the tender offer itself was formed through a fair process, ahead of the sophistication of the valuation model used.

What Happens When Minority Shareholders File a Price Determination Petition?

A price determination petition is heard by the court as a non-contentious matter, and the court itself sets the purchase price (Article 179-8, paragraph 1). Because statutory interest accrues on the determined amount for the period following the acquisition date (Article 179-8), the longer a price dispute drags on, the more it costs the special controlling shareholder — which tilts the incentives toward resolving it quickly. As a matter of practice, it is advisable to have the tender offer press releases, the third-party appraiser's valuation report, and the DCF assumptions organized and ready for submission to the court as soon as a petition is filed. As the JCOM case shows, the outcome of the proceeding turns less on the sophistication of the valuation model than on whether the fairness of the entire process can be demonstrated.

Timeline and Cost Benchmarks for a Squeeze-Out

Under the Companies Act, the target company must notify the selling shareholders no later than 20 days before the acquisition date (Article 179-4), and the window in which shareholders may petition for a price determination likewise runs only from the 20th day before the acquisition date through the day before it (Article 179-8, paragraph 1). At the statutory minimum, the period from notice to the acquisition date alone takes roughly three weeks. In practice, the preceding tender offer period and the third-party appraiser's valuation work add further time, so the total duration from public announcement to completion varies from deal to deal. Appraiser fees and legal costs likewise vary widely depending on deal size, complexity, and whether the price is contested; we were unable to identify published statistics on these figures, so no specific amounts are given here.

FAQ

Q1. Can a shareholder who opposes the squeeze-out stop the procedure?

An injunction is available under Article 179-7 of the Companies Act where the share cash-out demand violates the law, the target company fails to meet its notice or public announcement obligations, or the consideration is so unfair that it would prejudice the selling shareholders. The grounds are narrow, though — dissatisfaction with the price level alone does not qualify.

Q2. What options does a shareholder unhappy with the cash-out price have?

Under Article 179-8, paragraph 1 of the Companies Act, a shareholder may petition the court for a determination of price between the 20th day before the acquisition date and the day before it. As the JCOM case shows, the outcome largely turns on whether the underlying tender offer was conducted through procedures "generally recognized as fair."

Q3. How long does a squeeze-out typically take to complete?

Under the Companies Act, the target company must notify selling shareholders no later than 20 days before the acquisition date (Article 179-4), and a price determination petition must be filed by the day before the acquisition date (Article 179-8). That portion alone takes a statutory minimum of roughly three weeks, but the preceding tender offer period and valuation work extend the total timeline, which varies by deal.
