Findings by question
F1Quarterly and full-year results summaries (tanshin) published in English5/5
Consolidated Financial Results for the Three Months Ended June 30, 2026, dated 10 August 2026 like the Japanese 第1四半期決算短信 and listed in English IR News that day: 9 pages against the Japanese 10, with the qualitative information, the statements and the notes (single segment, so sales by device type in place of segment results). The half-year (Six Months Ended September 30, 2025) is 12 pages against 12. Every period back to 2021 is in the English Financial Results list. Complete and on the Japanese cycle. Source document →
F2English results summary is a full translation, not an excerpt5/5
The latest English tanshin, Consolidated Financial Results for the Three Months Ended June 30, 2026 (10 Aug 2026), is 9 pages against the Japanese 10. Its contents match: outline of results (with sales by device type in place of segment results), financial position, the forecast explanation, the quarterly balance sheet and income/comprehensive income statements, and the notes (going concern, shareholders' equity, cash-flow note, segment note). The FY March 2026 English tanshin (13 May 2026) is 24 pages against the Japanese 23. It matches section for section: outline of results, financial position, cash flows, prospects, accounting-standards stance, the four statements, notes (basis of preparation, segment and related information, per share, subsequent events), and production/orders/sales. A whole translation. Source document →
F3Financial statements including notes available in English5/5
The Q1 FY2026 English tanshin (10 Aug 2026) carries the quarterly balance sheet, the income and comprehensive income statements, and the same notes as the Japanese. Neither language has a Q1 cash-flow statement; both have the cash-flow note instead. The FY March 2026 English tanshin (13 May 2026) has all four statements, with the notes on basis of preparation, segments and related information (sales by product and region), per-share data and subsequent events. Full statements and notes for the latest period. Source document →
F4Annual securities report available in English in any form0/5
The English IR menu (Financial Results, Briefing, Integrated Report, Other Timely Disclosure Documents, Stock Overview, Shareholders' Meeting) carries no securities report; the Japanese side has a 有価証券報告書 page with no English counterpart, and the English governance page mentions the Securities Report without linking one. No yuho in English under any name.
F5Segment revenue and profit disclosed in English, consistent definitions5/5
Riken Keiki is a single-segment company, and the English says so. Every tanshin states 'As the Group engages in a single segment of the manufacture and sale of various types of industrial measurement devices ... the disclosure of business segment information has been omitted.' In its place, every quarter's English tanshin gives sales by device type. Q1 FY2026: fixed ¥9,088m (+3.6%), portable ¥5,743m (+28.0%), other ¥371m. FY2025: fixed ¥33,616m, portable ¥20,238m, other ¥1,356m. The year-end note adds sales by product and by region. Every English deck adds orders by device type, overseas sales by region, and sales by customer industry, the last with the regional method change flagged (from Q4 FY2025). Scored on the device-type lines, which are stated and consistent every period. Source document →
F6Multi-year financial data file (Excel or CSV) downloadable in English0/5
No Excel or CSV file on the English IR site. We checked the IR top, IR News (6 pages), Financial Results, Financial Results Briefing, Mid-Term Management Plan, Integrated Report, Other Timely Disclosure Documents, Stock Overview, Stock Price (a link to Yahoo Finance), IR Calendar and Shareholders' Meeting for xls/csv/zip/excel links. There are none. Multi-year figures exist only as PDF charts: 7 years of sales, OP, orders, region and industry mix in the decks, and five years of cash-flow indicators in the tanshin. The Japanese IR top has a ZIP 'IR資料一括ダウンロード' of the latest PDFs, with no English counterpart; it is not a data file either.
F7Guidance disclosed in English with the basis explained4/5
The FY March 2026 English tanshin (13 May 2026, '(4) Prospects for the Future') and deck (p15) give the FY3/2027 forecast with the first half: sales ¥60.0bn, OP ¥12.7bn, ordinary ¥13.0bn, net ¥9.6bn, EPS ¥211.19, dividend ¥60. The basis is a market view. Semiconductor investment in advanced fields continues on generative-AI and data-centre demand, there is broad-based demand in North America, and the overseas semiconductor share is to be expanded with multi-point tape-type detectors. The temporary OP-margin decline is put down to investment in organisation and pricing strategy, and cost pass-through is noted. No FX assumption and no device-type or regional forecast is given. The Q1 tanshin (10 Aug 2026) says the forecast is unchanged, and there were no revisions in the year. Forecast with part of the basis (market view only). Source document →
F8English financial disclosure current to the latest Japanese filing period5/5
English results for the three months to 30 June 2026 published 10 August 2026, the same period and day as the Japanese first-quarter tanshin. Source document →
S1Medium-term management plan in English with numerical targets5/5
The English Medium-Term Management Plan from FY2026 to FY2028 (23 pages, the same as the Japanese 中期経営計画 2027年3月期～2029年3月期 at 23 pages) is complete. It reviews the previous plan, then covers the business environment, strategic direction, business strategy and financial strategy. Targets: FY2028 sales ¥70.0bn, OP ¥14.0bn or more, OP margin 20% or more, with an annual path (¥60.0/65.0/70.0bn sales; ¥12.7/13.3/14.0bn OP), ROE 10% or more against a 7% cost of equity, payout over 30%, DOE about 3%, total return about 40% (about ¥14.0bn cumulative), buybacks up to about ¥5.0bn, overseas sales ratio target 50%, and a three-year cash allocation (operating CF ¥32.0bn or more). The English IR News lists it on 13 May 2026, the Japanese TDnet date. Caveat: both the English and the Japanese website PDFs were created 18 May (the English modified 22 May), so on the listing-date rule this is same day. As complete as the Japanese, current. Source document →
S2IR presentations published in English5/5
The English Financial Results Briefing page mirrors the Japanese 決算説明関連 page item for item: decks for Q1 FY2026 (August 2026, 13 pages), the FY2025 full year (May 2026, 16 pages), Q3 and the half year, plus the English Q&A Summary of the May 2026 results and medium-term plan briefing (7 pages) and an English briefing video. The Japanese side publishes no deck for periods the English lacks. Every period, with the supplement. Source document →
S3English equity-story or investment-highlights page5/5
The English IR menu has a dedicated 'Reason for Riken's Growth' page framed for investors in three parts: What does RIKEN KEIKI do? / What are the strengths? / What is it aiming for? The strengths are quantified: about 70% share of gas detectors in Japanese semiconductor fabs, about 40% of sales to the semiconductor industry, in-house sensor development (Kasukabe R&D and production centres, 2015/2020), and a stable maintenance business. It adds consolidated sales of ¥55.2bn and an overseas ratio of 47.3% in FY March 2026, and links to the decks, the plan and the integrated report. A dedicated page with quantified strengths. Source document →
S4Growth drivers identified and quantified in English4/5
The drivers are named across the English plan, deck and Reason page. Semiconductors are the priority market, on AI and data centres, and shipping is the second (the plan's market-attractiveness table). The overseas push targets a 50% overseas sales ratio (47.3% now), focused on East Asia and North America with multi-point tape-type detectors and the FPM-80A. Maintenance services are expected to restore margin, and methanation and decarbonisation are named as a new field. Some are quantified: a 70% domestic semiconductor share, about 40% of sales to semiconductors, maintenance at 42.1% of non-consolidated sales, regional and industry sales histories, and the ¥70bn target. There is no market size or capacity figure, and no contribution of each driver to the target. Named, some quantified. Source document →
S5Results-briefing transcripts or Q&A published in English4/5
Only one briefing has a Q&A in either language: the 14 May 2026 results and new medium-term plan web briefing. The English 'Q&A Summary from Web Financial Results and New Medium-Term Management Plan Briefing' (7 pp) matches the Japanese 質疑応答要旨 (7 pp). Neither page dates the item, and the English IR News does not list it separately. On PDF creation dates the English is 1 Jun 2026 against the Japanese 27 May 2026, about five days later. Other briefings (Q1, H1, Q3) have no Q&A in either language; there are English and Japanese briefing videos for the full year. Every Q&A the Japanese publishes, but a few days late. Source document →
S6Integrated or annual report available in English4/5
Latest English edition is Integrated Report 2025, 46 pages (file dated 28 October 2025), which states it covers the fiscal year ended March 31, 2025 - same page count as the Japanese 2025 edition. The Japanese side already offers 統合報告書 2026 (56 pages, PDF created 1 October 2026, judged from the PDF creation date). Complete report, one edition behind. Source document →
S7Progress against the previous plan, including misses, explained in English5/5
The new English plan opens with a dated review of the FY2023-FY2025 plan (pp2-4), target against actual. Sales: target ¥50.0bn or more, result ¥55.2bn. OP: target ¥12.0bn or more, result ¥12.4bn. ROE: double digits kept every year (12.3/10.7/12.2%). Dividend: increased every year (¥40/45/55). A year-by-year chart sets the plan's sales path (¥46.4/48.0/50.0bn) against results. Variances are explained: sales above plan, OP met on volume and price increases since 2H FY2025, and the margin trending down on raw-material costs. Previous plan's targets against actuals, explained. Source document →
G1Corporate governance report available in English5/5
The Corporate Governance Report filed with the TSE, in English, 14 pages, 'Last updated: June 25, 2026', announced in English IR News the same day and linked from the English Corporate governance page. Current. Source document →
G2Director biographies in English with tenure, expertise and independence5/5
Integrated Report 2025 (English, pp30-31, 'Board of Directors as of July 1, 2025') gives every director a profile: date of birth, career summary, attendance, shares owned and 'Tenure as director'. That covers Matsumoto 16 years, Kobu 8, Kizaki 6, Nakano 14, Taga 6, Uematsu 4 and Takemoto newly elected, plus Chairman Kobayashi (22), who has since left. The June 2026 English AGM notice updates the three executive candidates with full careers, tenure (17/9/7 years) and reasons for nomination. The English Corporate Governance Report (25 Jun 2026) marks Taga, Uematsu and Takemoto as independent, with reasons for designation and expertise (corporate management, law, finance). The English Executive Team page flags the outside directors. Every current director has tenure, career and independence in English. Source document →
G3Board skills matrix published in English5/5
The English Notice of the 120th AGM (29 May 2026, p7) has a skills matrix for all seven directors of the post-AGM board: Matsumoto, Kobu, Kizaki, Nakano, Taga, Uematsu and Takemoto. It covers ten skills: corporate management, international business, sales/marketing, technology/R&D, production, corporate governance, finance/accounting, IT/digital, human resources and strategy/sustainability. Integrated Report 2025 has the previous year's matrix. The current matrix in English. Source document →
G4Executive remuneration structure and its performance linkage explained in English5/5
Integrated Report 2025 (English, p28) sets out the structure: fixed, performance-linked, and restricted stock for executive directors; fixed only for Audit and Supervisory Committee members. The KPI is consolidated operating profit, explained as an MTP target, with the target ¥11,600m against the actual ¥11,476m used. Amounts are given by type: executive directors ¥176.0m (fixed 87.1, performance-linked 67.4, restricted stock 21.6, 4 people), inside ASC member ¥22.4m, outside directors ¥15.1m. The pay mix rule is stated: there is no fixed ratio, but the performance-linked and stock share rises with position. The English CG Report (25 Jun 2026) repeats the structure and adds the cap: performance-linked pay at most 3% of consolidated operating income. The amounts are for the prior year. Structure, KPI and amounts by type. Source document →
G5AGM notice in English with sufficient lead time to vote4/5
Notice of the 120th Annual General Meeting of Shareholders in English, listed on 29 May 2026 (file created 26 May) for a meeting on 25 June - 27 days - 7 pages with the Reference Documents for the single proposal (election of three directors) with each candidate's career and reasons for nomination. It tells the reader to vote in writing or via the internet by 5:10 p.m. on 24 June; no Japanese-only label on the voting route (the '(in Japanese)' tags attach to the materials-posting websites). Re-checked 23 Oct 2026 (G5 voting-site sweep, after the independent audit): the company's shareholder pages name Mizuho Trust & Banking as share registrar, whose voting website (soukai.mizuho-tb.co.jp) is in Japanese only, with no English option, as for ESPEC (6859) and Nitto Boseki (3110). Every proposal in English, but a Japanese-only voting route, so 4. Source document →
G6Shareholder vote results disclosed in English0/5
The English Shareholders' Meeting page lists the 116th to 120th notices only, and English IR News and Other Timely Disclosure Documents carry no resolutions or voting results. The Japanese side posted 臨時報告書(議決権行使結果) and 第120回定時株主総会決議ご通知 on 25-26 June 2026; no English counterpart.
G7Cross-shareholdings in English with reduction schedule and rationale2/5
The only English treatment is the Corporate Governance Report (25 Jun 2026), Principle 1-4. Shares are held where there is a reasonable business reason and profitability (dividend yield, sound issuer), and are considered for sale otherwise. The Board verified the individual stocks in May 2026, and voting is examined on earnings, payout and ROE. We found no count, no amount, no per-stock list and no reduction target in English: not in the CG Report, Integrated Report 2025, the plan, or the cost-of-capital notice (Aug 2025). The yuho, which carries the holdings table, is Japanese only. Governance-report policy only. Source document →

The same sample of 25 links (see O2), from 2021 to Aug 2026, all opened in the rendered browser as PDFs with text. None was dead.

The question this leaves open
Investor question: How much of the outperformance is recurring, and what capital earned it? IR preparation: bridge segment growth, invested capital, margins and ROIC.
Our analysis, not a company statement
Balance sheet and capital-policy indicators
A source-backed first-pass capital-efficiency, balance-sheet and governance reading, separate from the accountability score.
Cash use and returns
Riken Keiki exceeded its FY2026 sales and operating-profit targets as semiconductor, construction, maintenance and overseas demand expanded.
Capital structure
The balance sheet remained highly equity funded and dividends increased, but the completed plan did not publish an explicit optimal-capital or leverage range.
Governance of capital decisions
Management disclosed plan targets and final actuals, yet the plan lacked quantified ROIC, capital allocation and project hurdle rates.
Preliminary and not scored: a selected-source reading, reviewed 30 September 2026. Surplus cash, leases, maturities, project ROIC, cost of capital, committed spend and peer comparability are not fully assessed; none enters the accountability score. Figures are the company’s own reported numbers; a large cash balance is not called excess without a defensible operating reserve and investment plan. Every company with a balance-sheet reading →
