# 株式分配 (kabushiki bunpai) — Japan share-distribution / pure spin-off regime (適格株式分配) and how it differs from パーシャルスピンオフ

## Wiki route

This entry sits under [[corporate-strategy/INDEX|corporate-strategy INDEX]] and routes into [[finance/INDEX|finance INDEX]] for the capital-markets overlay. It is the **distribution-side** spin-off mechanism — the in-kind dividend that delivers subsidiary shares to a parent's own shareholders. It now also absorbs the **パーシャルスピンオフ (partial spin-off, retained-stake)** regime, covered in [§6](#6-パーシャルスピンオフ--partial-spin-off-2023-special-measure) below. Read it alongside [[corporate-strategy/japan-kaisha-bunkatsu-tax-regime|会社分割 tax regime]] (the *carve-out plumbing* that usually precedes a distribution) and [[corporate-strategy/spinoff-decision-tree-japan|the spinoff decision tree]] for placement against every other divestiture route.

## TL;DR

**株式分配 (kabushiki bunpai, share distribution)** is the Japanese mechanism by which a parent company distributes **the shares of a wholly-owned subsidiary to its own shareholders** as an in-kind dividend (現物分配). It is the legal core of a **classic / full spin-off (スピンオフ)** — the parent ends up owning **nothing** of the subsidiary, which becomes an independent listed (or listable) company held directly by the former parent's shareholders in proportion to their existing holdings.

The key distinction this entry settles — the one the [[corporate-strategy/INDEX|domain index]] flags as "commonly confused":

- **株式分配 (full spin-off)** — parent distributes **100%** of the subsidiary and retains **0%**. The qualified form is **適格株式分配**, created by the 2017 spin-off tax reform.
- **パーシャルスピンオフ (partial spin-off)** — parent distributes most of the subsidiary but **retains up to 20%**. This is the 2023 special measure — a relaxation built *on top of* the 株式分配 framework — detailed in [§6](#6-パーシャルスピンオフ--partial-spin-off-2023-special-measure) below.
- **会社分割 (company split)** — the *asset-level* mechanism that moves a **business** into a subsidiary; it is the **plumbing** often used to create the wholly-owned subsidiary that is then distributed. See [[corporate-strategy/japan-kaisha-bunkatsu-tax-regime|the 会社分割 tax regime]].

In short: **会社分割 creates the box, 株式分配 hands the box to shareholders.** A "spinoff" in the everyday sense is usually 新設分割 (to form the subsidiary) followed by 適格株式分配 (to distribute it), executed as one planned sequence.

The statutory layer:

- **Companies Act art. 454 / 剰余金の配当** governs the in-kind distribution (現物配当) used to deliver the shares; a 100%-subsidiary distribution to all shareholders pro rata is the qualifying pattern.
- **Corporation Tax Act art. 2(12-15-2) / 2(12-15-3)** and surrounding 組織再編成 provisions define **適格株式分配** and its tax-deferred treatment.
- **適格株式分配** turns off both the **corporate-level gain** on the distributed shares and the **shareholder-level deemed dividend / capital gain** that a normal in-kind dividend would trigger.

## 1. Two Faces of a Spin-off in Japanese Tax Law

The 2017 spin-off reform actually defined **two** qualified spin-off patterns. Both aim at the same economic result — a business becomes an independent company held by the original shareholders — but they reach it differently:

| Pattern | Mechanism | What moves | Typical starting point |
|---|---|---|---|
| **適格株式分配 (qualified share distribution)** | 現物分配 of subsidiary shares | **Shares** of an existing wholly-owned subsidiary | Parent already holds the target as a 100% subsidiary |
| **単独新設分割型分割 (independent incorporation-type split)** | 新設分割 whose consideration goes **straight to the parent's shareholders** | **A business**, carved into a new company whose shares land with shareholders | Business still sits inside the parent and must first be carved out |

Sources: the two spin-off forms and their legal / tax structure are summarized in METI's current spin-off guide and the Ministry of Finance's organization-restructuring tax overview. ^[Sources: https://www.meti.go.jp/policy/economy/keiei_innovation/keizaihousei/oshirase/spinoff-kaitei_20260522.html; https://www.mof.go.jp/tax_policy/summary/corporation/c06.htm.]

This entry focuses on **適格株式分配**, the more common route, because most spin-offs first use a [[corporate-strategy/japan-kaisha-bunkatsu-tax-regime|新設分割]] to put the business into a clean 100% subsidiary, *then* distribute that subsidiary via 株式分配. The split-type-split (分割型分割) collapses those two steps into one for businesses not yet siloed.

## 2. What "株式分配" Means Precisely

株式分配 is a **defined term** in the Corporation Tax Act: a 現物分配 (in-kind distribution) in which the distributing corporation hands over the shares of a **完全子法人 (wholly-owned subsidiary)** to its shareholders, such that after the distribution the shareholders hold the subsidiary directly **in proportion to their shareholding in the parent**.

Three features are essential:

1. **It is a dividend, not a sale.** No cash changes hands at the shareholder level; shareholders receive subsidiary stock instead of (or as) a distribution out of the parent.
2. **It must be pro rata.** Every shareholder receives subsidiary shares strictly in line with their existing parent stake. A non-pro-rata or selective distribution breaks the regime.
3. **The subsidiary must be 100%-owned immediately before.** 株式分配 distributes a 完全子法人; partial subsidiaries do not qualify (that is precisely the gap the パーシャルスピンオフ regime — [§6](#6-パーシャルスピンオフ--partial-spin-off-2023-special-measure) — later addressed from the *retention* side).

## 3. 適格株式分配 — the Qualified Tests

A bare 現物分配 of appreciated subsidiary shares would normally trigger tax twice — a corporate gain at the parent and a deemed dividend / capital gain at the shareholders. **適格株式分配** switches both off. To qualify, the distribution must satisfy a set of tests whose spirit matches the broader 組織再編成 framework in [[corporate-strategy/japan-kaisha-bunkatsu-tax-regime|the 会社分割 regime]]:

- **No prior control relationship that persists** — the parent must *not* be under the control of another party that would continue to control the spun-off company; the spin-off must genuinely cut the subsidiary loose (the "independence" spirit of a true spin-off).
- **No expected post-distribution control** — there must be no anticipated arrangement re-establishing a controlling relationship over the spun-off company after the distribution.
- **Pro-rata distribution of all subsidiary shares** — every share of the 完全子法人 is distributed, strictly in proportion to shareholders' parent holdings.
- **Employee retention (従業者継続)** — roughly **80%** of the subsidiary's employees are expected to continue in its business after the distribution.
- **Business continuation (事業継続)** — the subsidiary's main business is expected to continue after the spin-off.
- **Specified-officer continuation** — key officers (特定役員) of the subsidiary are expected to continue.

When these hold, the distributed shares move at **book value**, the parent recognizes **no gain**, and the shareholders are treated as simply **rolling their basis** into the new direct holding — **no immediate tax** at either level.

## 4. Tax Consequences — Qualified vs Non-Qualified

| | 適格株式分配 (qualified) | 非適格 現物分配 (non-qualified) |
|---|---|---|
| Parent-level gain on distributed shares | No immediate recognition under the qualifying rules; book-value treatment applies | Mark-to-market treatment can recognize embedded gain |
| Shareholder-level tax | No immediate recognition under the qualifying rules; basis allocation applies | **Deemed dividend (みなし配当)** and other taxable consequences can arise |
| Subsidiary's tax attributes | Generally preserved | Disturbed; can interact with loss-limitation rules |
| Net effect | Tax-deferred separation, subject to all qualification rules | Potential corporate- and shareholder-level taxation |

Sources: the table states only the high-level distinction between qualified and non-qualified treatment. Exact basis allocation, loss restrictions, and shareholder consequences must be determined under current tax law for the transaction. ^[Sources: https://www.mof.go.jp/tax_policy/summary/corporation/c06.htm; https://www.nta.go.jp/law/tsutatsu/kihon/hojin/01/01_04_05.htm.]

The shareholder-level **deemed dividend (みなし配当)** is the headline risk a non-qualified distribution creates: shareholders can owe dividend tax on stock they merely received in place of their old shares, with no cash to pay it — the same "tax on illiquid receipt" trap that the [[corporate-strategy/japan-business-succession-jigyou-shoukei|business-succession regime]] tackles on the inheritance side. 適格 status is therefore not optional in practice; it is the whole point.

## 5. 株式分配 vs パーシャルスピンオフ vs 会社分割 — the Confusion Settled

This is the comparison the domain index singles out. The three are different layers, not alternatives:

| | 適格株式分配 (full spin-off) | パーシャルスピンオフ (partial) | 会社分割 (company split) |
|---|---|---|---|
| Level it operates on | **Share** distribution to shareholders | **Share** distribution to shareholders | **Asset / business** transfer |
| Parent's residual stake | **0%** | **Less than 20%** after the distribution under the current special measure | N/A (no distribution by itself) |
| Reaches shareholders directly? | Yes — they hold the subsidiary | Yes — minus the retained slice | No — shares go to a successor company |
| Role | Hands an existing subsidiary to shareholders | Same, but keeps a minority alliance stake | **Creates** the subsidiary to be distributed |
| Regime | 適格株式分配 (2017) | Special measure (2023) — see [§6](#6-パーシャルスピンオフ--partial-spin-off-2023-special-measure) | 適格分割 — see [[corporate-strategy/japan-kaisha-bunkatsu-tax-regime|会社分割 tax regime]] |

Sources: METI's May 2026 guide reflects the FY2026 partial-spin-off amendments; the Companies Act and Ministry of Finance tax summary support the company-split and distribution boundaries. ^[Sources: https://www.meti.go.jp/policy/economy/keiei_innovation/keizaihousei/oshirase/spinoff-kaitei_20260522.html; https://www.mof.go.jp/tax_policy/tax_reform/outline/fy2026/08taikou_03.htm; https://laws.e-gov.go.jp/document?lawid=417AC0000000086.]

The decisive mental model: **会社分割 is the verb that builds the subsidiary; 株式分配 is the verb that gives it away; パーシャルスピンオフ is 株式分配 with a 20% leash.** A complete classic spin-off is usually **新設分割 → 適格株式分配** run as a single plan. The full option set sits in [[corporate-strategy/spinoff-decision-tree-japan|the spinoff decision tree]].

## 6. パーシャルスピンオフ — partial spin-off (2023 special measure)

The **パーシャルスピンオフ** regime is the *retained-stake* sibling of 適格株式分配. Created by the **2023年度 (令和5年度) 税制改正**, it relaxes the strict "distribute 100%, retain 0%" rule of 適格株式分配 so that a parent can hand most of a wholly-owned subsidiary to its shareholders **while keeping a minority stake** and still obtain tax-deferred treatment.

### 6.1 制度構造 (regime essentials)

| 項目 | 内容 |
|---|---|
| 対象 | 完全子会社を切り出す株式分配型スピンオフ (a 株式分配 of a 100%-owned subsidiary) |
| 特徴 | 親会社が切り出し後も一部持分を残せる — the parent may keep a residual stake |
| 持分上限 | 分配直後の親会社保有割合が **20% 未満** |
| 税務効果 | 要件充足時は親会社・株主の即時課税を繰り延べる |
| 政策目的 | 企業グループの事業ポートフォリオ再編促進 |
| 認定要件 | **産業競争力強化法の事業再編計画**の認定 (METI certification of a business-restructuring plan under the Industrial Competitiveness Enhancement Act) |

Sources: this is a non-exhaustive current-regime map based on the FY2026 tax-reform outline and METI's May 2026 guide. It does not replace the statutory qualification and plan-certification tests. ^[Sources: https://www.mof.go.jp/tax_policy/tax_reform/outline/fy2026/08taikou_03.htm; https://www.meti.go.jp/policy/economy/keiei_innovation/keizaihousei/oshirase/spinoff-kaitei_20260522.html; https://www.meti.go.jp/policy/economy/keiei_innovation/keizaihousei/saihenzeisei/spin-off.html.]

The decisive parameter versus full 株式分配 is the **retained stake**: a full spin-off retains **0%**, the partial regime allows **up to ~20%**, letting the parent keep a strategic alliance, brand, or cooperation link rather than severing the subsidiary entirely. Unlike a plain 適格株式分配, the partial measure is gated on **産業競争力強化法** certification — it is a policy-conditioned relaxation, not an automatic carve-out, and applies only to a 株式分配 of a 完全子会社, not to arbitrary 会社分割 / 事業譲渡.

### 6.2 Typical transaction flow

| Step | 処理 | 実務論点 |
|---|---|---|
| 1 | 切り出し対象事業を完全子会社に整理 | 事業・資産・負債・人員移管 (often via a [[corporate-strategy/japan-kaisha-bunkatsu-tax-regime|会社分割]]) |
| 2 | 事業再編計画・上場準備 | METI 認定 (産業競争力強化法)、TSE 審査、監査 |
| 3 | 親会社が子会社株式を現物分配 | 配当財源、会社法手続 (Companies Act art. 454 in-kind dividend) |
| 4 | 親会社が一部持分を保有継続 | **20% 未満**要件、ブランド・提携維持 |
| 5 | 子会社が独立上場 | 株主は親会社株式と子会社株式を併有 |

Sources: the flow is an analytical sequence consistent with METI's current guide and Sony's completed transaction. Certification, listing, corporate-law, tax, and operational steps can overlap and differ by case. ^[Sources: https://www.meti.go.jp/policy/economy/keiei_innovation/keizaihousei/oshirase/spinoff-kaitei_20260522.html; https://www.sony.com/en/SonyInfo/IR/library/SFG_pso/.]

### 6.3 Worked example and policy status

The first high-profile domestic application is the **Sony Group → Sony Financial Group** partial spin-off. METI certified the plan in February 2024; Sony Financial Group listed on **2025-09-29**, and Sony reported completion of the partial spin-off on **2025-10-01**. The full worked example lives in [[business/sony-fg-partial-spinoff-case|Sony FG partial spinoff case]].

Policy detail is still moving: METI revised the guide in **May 2026** after the FY2026 tax reform changed partial-spin-off requirements. Treat all parameters as needing re-confirmation against current METI / MOF / NTA materials per transaction.

## 7. Why a Parent Runs a Full Spin-off

- **Pure-play focus / conglomerate discount**: separating an unrelated business lets each company be valued on its own multiple — the classic argument that also drives the cases in [[business/japan-listed-corp-strategic-restructuring-matrix|the listed-corp strategic-restructuring matrix]].
- **No-cash separation**: unlike a sale, a spin-off needs **no buyer and no financing** — value passes to existing shareholders rather than to a third party, contrasting with the cash routes in [[finance/japan-mbo-and-squeeze-out-process|the MBO / squeeze-out process]].
- **Management incentive alignment**: the spun-off company gets its own equity currency and an independent board.
- **Tax neutrality**: 適格株式分配 makes the separation tax-free at both levels — the feature that distinguishes a spin-off from an outright [[finance/japan-acquisition-finance|financed]] disposal, which is taxable to the seller.

The trade-off versus パーシャルスピンオフ is alliance retention: a **full** 株式分配 severs the parent entirely, whereas the partial regime ([§6](#6-パーシャルスピンオフ--partial-spin-off-2023-special-measure)) lets the parent keep a strategic minority — the reason the 2023 measure was added.

## 8. Counterpoints and Caveats

- **適格 is the load-bearing requirement.** A spin-off that fails the qualified tests inflicts a double tax hit (corporate gain + shareholder deemed dividend) and is rarely worth doing. Confirm 適格 status per transaction against NTA guidance.
- **株式分配 ≠ パーシャルスピンオフ.** They share machinery but differ on the single most important parameter — retained stake (0% vs up to 20%). Do not treat them as interchangeable.
- **It needs a 100% subsidiary first.** If the business is still inside the parent, a [[corporate-strategy/japan-kaisha-bunkatsu-tax-regime|会社分割]] (or the 分割型分割 one-step variant) must precede the distribution.
- **Listing mechanics apply.** Spinning off a business as an independently listed company invokes exchange listing and disclosure rules — see [[securities/japan-ipo-listing-disclosure-route|the IPO listing / disclosure route]] — and FSA disclosure obligations referenced in [[finance/japan-large-shareholding-disclosure|large-shareholding disclosure]].
- **Policy guidance evolves.** METI refreshed its spin-off guide in May 2026 after the FY2026 amendments; treat regime detail as needing re-confirmation against current METI / MOF / NTA materials.
