Why does a single 2023 letter from the Tokyo Stock Exchange still matter in 2026? Because it created the first enforcement mechanism I’ve seen actually move the needle on Japan’s chronic book-value discount — and that’s exactly why this reform cycle deserves more than a one-time headline treatment.
Investment Thesis
Author’s View: Constructive | Fair Value Estimate (Author’s Model): Thesis-based — no single-ticker target; framework favors Prime-listed, sub-1x PBR companies with active buybacks
- Core thesis: TSE’s March 2023 request created a monthly, published compliance list — turning a governance ask into a repeatable, verifiable screen instead of a one-time disclosure exercise.
- Numeric backing: A meaningful share of Prime-listed firms still traded below 1x book value years after the mandate, while aggregate Japan buyback activity has run at record or near-record levels in multiple years since 2023 (JPX; verify current figures at source).
- Top risk: Compliance is self-reported and uneven — many firms file boilerplate language without operational follow-through, and downgrade enforcement against large-cap laggards has shown signs of softening.
Last updated: July 2026
Which Prime-listed companies are actually complying with Tokyo’s cost-of-capital mandate, and which are just filing paperwork to stay off a watch list? That’s the question this framework is built to answer, using the same Japanese-language disclosure trail that Tokyo-based institutional desks already track daily.

Why “Japan Is Cheap” Sounds Different in 2026
Foreign investors have heard “Japan is cheap” before. The 2013 Abenomics rally briefly pulled index levels off multi-decade lows and introduced Japan’s first formal corporate governance code.
But by the early 2020s many international allocators had filed Japan under “value trap” — a market that looked statistically cheap on P/E and P/B but never re-rated, because management teams treated governance-code compliance as a checkbox exercise rather than a capital-allocation mandate.
The intellectual groundwork for today’s reform goes back further than most English coverage acknowledges. METI’s 2014 “Ito Review” (伊藤レポート), chaired by Hitotsubashi University professor Kunio Ito, first proposed an 8% return-on-equity benchmark for Japanese corporates as a capital-efficiency floor. (METI, English portal)
A 2017 follow-up, known as Ito Report 2.0, shifted the conversation toward intangibles and long-term value creation. English-language coverage of the current reform cycle cites the 8% ROE figure constantly but rarely engages with the original Japanese policy reasoning behind it, or how directly it maps onto today’s PBR mandate.
Berkshire Hathaway’s public, escalating stakes in Japan’s sogo shosha since 2020 are frequently cited by English-language commentators as external validation that a large foreign allocator already sees Japan’s capital-discipline shift as real. That’s a useful anchor, not a signal to follow blindly into any specific name. (Berkshire Hathaway shareholder letters)
The Abenomics-era governance code and why it underdelivered
The FSA’s Corporate Governance Code (first published June 2015, revised 2018 and 2021) asked listed companies to “comply or explain” on board independence, cross-shareholding disclosure, and capital efficiency. (FSA, Corporate Governance Code)
Compliance was nearly universal on paper. Actual capital discipline lagged, because the code carried no enforcement trigger tied to a company’s own stock price — a firm could explain away a sub-1x PBR indefinitely without consequence.
What’s structurally different about the 2022–2026 reform sequence
The current sequence narrows the room to hide at each step. April 2022 reset listing criteria first. March 2023 attached a specific, named metric — price-to-book below 1x — to individual companies.
January 2024 turned that into a public, monthly-updated roster. March 2025 forced firms that still hadn’t met free-float and liquidity thresholds to act or face downgrade. Layered together, these function less like a single announcement and more like a compliance pipeline with recurring checkpoints.
The April 2022 Market Restructuring — Mechanics for Foreign Investors
Many foreign investors conflate “TSE reform” with the 2023 PBR letter alone, but the precondition was a market-segment overhaul effective April 4, 2022. TSE replaced the old First Section / Second Section / Mothers / JASDAQ structure with three segments: Prime, Standard, and Growth. (JPX, market segments)
Prime vs. Standard vs. Growth — what actually separates them
Prime is built for large, liquid companies with global institutional investor bases, carrying the strictest criteria on tradable share market cap, free-float ratio, and average daily trading value. Standard serves mid-sized, domestically-oriented companies meeting a baseline liquidity and governance bar. Growth is reserved for earlier-stage, high-growth companies with a business-plan disclosure requirement in lieu of a long track record.
For a dividend-focused foreign investor, Prime listing alone is a useful pre-screen: it filters out most companies too small or illiquid for a US brokerage account to trade efficiently, the same function a minimum market-cap screen serves on a US dividend ETF like SCHD.
The grace-period cliff and forced downgrades as a screening signal
Companies that didn’t meet Prime’s criteria at the April 2022 cutover weren’t delisted outright. TSE granted a transition period, provided the company filed a periodic “plan for compliance” (適合計画書) explaining how it intended to meet the threshold.
That grace period effectively closed around March 2025, at which point firms still short of the criteria faced downgrade to Standard. A company’s compliance-plan filing history — targets consistently missed and pushed back, or steadily closed — is itself a signal about management credibility that’s easy to check on JPX’s site but rarely discussed in English-language research.
The PBR Mandate — How a Single Letter Changed Boardroom Behavior
On March 31, 2023, TSE issued a request to all Prime and Standard-listed companies titled “資本コストや株価を意識した経営の実現に向けた対応について” — “Action to Implement Management Conscious of Cost of Capital and Stock Price.” (JPX, cost-of-capital request)
The request specifically targeted companies with a price-to-book ratio persistently below 1x, asking them to disclose their current assessment, an analysis of the causes, and a concrete policy with specific initiatives. This is what I mean by “PBR governance pressure”: TSE using persistent sub-1x valuation, tied publicly to a company’s name, as leverage to force a capital-allocation response.
What TSE actually asked companies to disclose and do
The Japanese-language original uses the phrase “持続的・継続的” — “sustained and continuous” — to describe the standard of implementation expected. That phrasing is stricter than how the request is typically paraphrased in English financial media, which often shorthands it as a one-time “PBR disclosure requirement.”
TSE’s actual ask was for an ongoing management practice, re-affirmed and updated over time — not a single disclosure filed once and forgotten. Investors judging genuine versus cosmetic compliance should weight this distinction heavily.
The monthly “naming” list as a de facto enforcement tool
Starting in January 2024, TSE began compiling and publishing a list of companies that had disclosed initiatives responsive to the request, updated on a monthly cadence. (JPX, compliance disclosure list)
This is the mechanism that converts a governance code into something closer to a compliance regime: a company’s name either appears on the list or it doesn’t, and continued absence functions as a dated, public signal that institutional allocators can screen against directly.
The Numbers: Compliance Rates, Buybacks, and Cross-Shareholding Unwind
The headline framing under-describes the real-economy impact, which shows up in three data series worth tracking directly rather than trusting a secondhand summary.
Reading the TSE monthly compliance list correctly
The share of Prime-listed companies appearing on TSE’s disclosure list was a minority in the early months after the January 2024 launch and has climbed since. The precise current percentage moves monthly — pull the latest figure directly from JPX’s release rather than a stale secondhand number.
Separately, the share of Prime-listed companies trading below 1x book value has narrowed from the roughly one-third-to-half range commonly cited around the 2023 request, though it remains a meaningful minority as of this July 2026 update. Verify the current reading at JPX before acting on it.
Buyback totals and cross-shareholding unwind as the real tell
Japan’s aggregate share buyback announcements have run at record or near-record annual levels in multiple years since the 2023 request, a pattern documented in JPX’s own market data and covered extensively by Nikkei. (Nikkei Asia)
Separately, Bank of Japan Flow of Funds data shows a multi-year decline in listed companies’ cross-shareholding balances, consistent with boards unwinding strategic stakes to improve capital efficiency and free-float metrics at the same time. (Bank of Japan, Flow of Funds)
Buybacks alone can flatter PBR without underlying earnings growth. That’s precisely why the screening framework below pairs a PBR filter with a compliance-list and follow-through check, rather than using PBR in isolation.
Japan Edge: Japanese-Language Sources U.S. Investors Miss
TSE’s monthly compliance-disclosure spreadsheet and individual companies’ TDnet (適時開示) filings for buyback authorizations post in Japanese, during Japan market hours, well before English-language wire services summarize them. (TDnet, timely disclosure)
Cross-referencing a company’s EDINET buyback filing (自己株式取得に関するお知らせ) against its presence — or absence — on the TSE compliance list lets an investor flag “compliant on paper, inactive in practice” companies before that gap becomes consensus knowledge. (EDINET)
Concretely: search EDINET or TDnet for a company’s most recent 自己株式取得 (treasury share buyback) filing, note the authorized amount and filing date, then check whether that amount was actually executed by the following quarter’s 決算短信 (earnings summary), not just authorized and left dormant.
A gap between authorization and execution — visible only in the Japanese-language filing sequence — is a stronger tell than the English-language press release announcing the authorization alone.
Separately, Japanese retail and domestic-analyst sentiment on sites like みんかぶ and Yahoo!ファイナンス掲示板 has run noticeably more skeptical toward “compliance theater” among large-cap laggards than English-language sell-side notes on the same names — a divergence invisible to an investor who only reads English research. (Minkabu, Yahoo! Finance Japan)
Investor takeaway: Before trusting any English-language summary of a company’s reform compliance, pull its own TDnet/EDINET filing history directly — the filing dates and the authorized-versus-executed buyback gap tell you more than the headline does.
A Practical Screening Framework for Foreign Investors
None of the above is a stock pick. It’s a repeatable filter, closer in spirit to how a US dividend investor already screens the S&P Dividend Aristocrats than to a traditional “buy Japan” macro call.
Step 1 — Filter for Prime-listed + sub-1x PBR
Start with JPX’s own company search tools, or a screener like TradingView, to isolate Prime-listed companies trading below 1x price-to-book. (JPX, company data)
This roughly replicates what TSE’s March 2023 letter targeted — but plenty of sub-1x companies are cheap for good structural reasons, so treat this as a first filter, not a buy list.
Step 2 — Cross-check TSE compliance list status
Cross-reference each candidate against TSE’s monthly compliance disclosure list. A company appearing repeatedly, with updated (not merely repeated) language across multiple filings, is showing the “sustained and continuous” engagement the original request demanded.
A company absent from the list, or present with only a single stale filing from 2023, is a lower-conviction candidate regardless of how cheap its PBR looks.
Step 3 — Confirm capital-return follow-through via TDnet/EDINET
Finally, check the company’s TDnet and EDINET filing history for actual buyback execution and dividend-growth track record, not just authorization announcements. A same-day TDnet disclosure alert surfaces buyback and governance-plan announcements in Japanese well before English-language aggregators translate and republish them.
A worked example: reading one month’s compliance list
Picture a hypothetical Prime-listed industrial manufacturer trading at 0.8x book value. Its name appears on TSE’s compliance list from the initial January 2024 batch, but the attached disclosure text is identical, word-for-word, across three subsequent monthly updates.
Meanwhile, its EDINET buyback filing shows a mid-2023 authorization that was never fully executed by the following fiscal year-end. That combination — a static disclosure plus an unexecuted buyback — is the “compliant on paper, inactive in practice” pattern this framework is built to catch, and it’s only visible by reading the primary filings.
Risks and Counter-View
The framework above has real limits, and a foreign investor should weigh three specific ones before treating reform compliance as a standalone thesis.
Compliance theater — the gap between disclosure and execution
A large minority of Prime-listed companies still file boilerplate disclosures that satisfy the letter of TSE’s request without much operational follow-through. Downgrade enforcement against large-cap laggards has, at points, shown signs of political softening rather than strict application.
Buyback-driven PBR improvement can also be financial engineering — shrinking the denominator (book value or share count) without growing the numerator (earnings or ROE) does little for long-term dividend capacity even as it flatters the ratio.
Macro overhangs that could swamp the micro reform story
Yen strength and Bank of Japan policy-rate moves are a bigger swing factor for USD-based total returns than reform-driven re-rating in many scenarios. A sharp BOJ tightening cycle or rapid yen appreciation could compress multiples market-wide, overwhelming company-specific reform progress.
Worth noting explicitly: Japanese-language domestic sell-side and academic commentary — including coverage of JPX advisory council minutes, published only in Japanese — has been notably more skeptical about “genuine” versus “cosmetic” compliance than English-language sell-side notes on the same companies. That’s both a source of edge and a reminder that consensus optimism abroad may be running ahead of domestic assessment.
Bottom Line
Author’s View: Constructive on the framework, not on any single ticker. The multi-year enforcement sequence — restructuring, mandate, monthly naming, deadline — gives foreign investors something prior “Japan is cheap” cycles never had: a dated, public, cross-checkable compliance trail.
The realistic window is 12 to 18 months for the population of laggard-to-complier transitions to compress meaningfully, assuming enforcement doesn’t keep softening for large-cap names.

Compared with a US dividend ETF like SCHD, this framework isn’t a substitute — it’s a satellite allocation for investors willing to do primary-source screening in exchange for exposure to a re-rating catalyst that doesn’t exist in the US market. TradingView’s screener is a reasonable place to build the Prime + sub-1x PBR shortlist before cross-checking each name against TSE’s compliance list.
Frequently Asked Questions
Q: How do I calculate the after-tax dividend yield on a TSE Prime stock as a US investor?
Japan withholds dividend tax at a statutory 15.315% at source. With a valid W-8BEN on file, that rate can be reduced to 10% under the US-Japan tax treaty. In a taxable brokerage account, IRS Form 1116 may generally let you claim the withheld amount as a foreign tax credit; that credit is not available for shares held inside an IRA, so the withholding there is effectively a permanent cost.
Q: Can I buy TSE Prime-listed stocks directly from a US brokerage like IBKR?
Interactive Brokers offers direct TSE market access for eligible account holders, letting you buy shares in JPY without relying on an ADR. Availability and requirements vary, so confirm current TSE access and minimum balances directly with the broker before funding a position.
Q: What’s the fastest way to check if a company is actually complying, not just filing paperwork?
Pull the company’s filing history directly from TSE’s compliance disclosure list and cross-reference it against its EDINET or TDnet buyback and earnings filings. Repeated, updated disclosure language plus executed (not just authorized) buybacks is the strongest signal.
Q: Does a sub-1x PBR always mean a stock is undervalued?
No. A persistently low PBR can reflect a legitimate structural issue — declining end markets, poor capital allocation, or governance concerns — rather than a temporary mispricing. That’s why this framework pairs the PBR screen with compliance-list status and buyback follow-through rather than using PBR alone.
Q: How does yen movement affect returns from this strategy?
Because returns are measured in USD, yen depreciation against the dollar can offset or reverse gains from share-price re-rating, while yen appreciation can amplify them. Size positions treating FX as a separate, largely uncorrelated risk factor from the reform-compliance thesis itself.
How U.S. Investors Access TSE Prime-Listed Dividend Stocks
Most TSE Prime-listed companies trade only in Tokyo, in JPY, without a US-listed ADR — a handful of large-caps (Toyota, Sony, Mitsubishi UFJ among them) are exceptions with sponsored ADR programs. For the broader Prime-listed universe this framework screens, direct TSE access is generally required.
International investors can access TSE Prime stocks directly through:
- Interactive Brokers (IBKR) — direct TSE access, competitive JPY/USD conversion, widely used by US-based investors for direct Japan exposure.
- Saxo Bank — full TSE coverage, available to investors in many countries outside the US; a common choice for readers outside US brokerage jurisdictions.
- Webull — lower account minimums and growing TSE coverage, useful for smaller position sizes.
U.S. tax notes: Japan withholds dividend tax at a statutory 15.315% at source. With a valid W-8BEN on file with your broker, that rate can be reduced to 10% under the US-Japan tax treaty.
In a taxable brokerage account, IRS Form 1116 may generally allow you to claim the Japanese withholding as a foreign tax credit against US tax liability. That credit is not available for shares held in an IRA, where the withholding is a permanent, non-recoverable cost — a meaningful reason to weigh account placement before building a position.
