Chubu Electric's Nuclear Restart Collapses Under Its Own Rigged Data

Chubu Electric Pulls Hamaoka Restart Applications After Its Own Seismic Data Turns Out to Be Rigged

Chubu Electric Power told Japan's Nuclear Regulation Authority on September 14 that it is withdrawing every application tied to restarting Hamaoka Units 3 and 4, including the reactor installation change permits and related construction and safety-rule approvals. The move closes out more than a decade of regulatory review with no restart date on the horizon.

What changed: An independent investigation into how the utility selected the seismic wave data underpinning the reactors' earthquake safety case found that staff manipulated those selections for years and built paperwork to disguise it. The committee stopped short of calling the conduct outright falsification, but it did not find the company's actions to have been appropriate.

Why it matters: Chubu Electric's president and chairman are both stepping down as a result, and the utility now has to rebuild the credibility of its own safety review process from scratch before any future restart attempt at one of Japan's largest nuclear stations.

What to watch: No new timetable exists for Hamaoka 3 and 4. Chubu Electric has not said whether it will resubmit the applications once new seismic work is done, or how long that would take.

Accounting Red Flags

MATSUMOTO INC. Flags Going-Concern Doubt as Quarterly Cash Halves

MATSUMOTO INC. (TSE: 7901), the school-album and commercial printer, disclosed a material uncertainty about its ability to continue as a going concern in the quarterly earnings it filed. Cash and deposits fell ¥362mn during the three months to July 2026, to ¥313.9mn from ¥676.7mn at the end of April, while short-term borrowings held flat at ¥200mn. Funds on hand, cash minus outstanding loans, dropped ¥360.9mn from the prior year-end after a fourth straight year of negative operating cash flow, even as the net loss narrowed to ¥100mn.

Why it matters: A cash pile that halves in three months while borrowings stay flat is a funding problem, not an accounting footnote, and the company itself says financing for the next twelve months is not assured.

Hamai Industries Restates Five Years of Profit After Auditor Balks at Its Inventory Count

HAMAI INDUSTRIES LTD. (TSE: 6497) filed five amended annual securities reports with the Kanto Local Finance Bureau on September 14, covering every fiscal year from 2021 through 2025. The trigger: the audit firm lined up to review the year ending this December withdrew from the assignment at Hamai's March shareholders meeting, telling the company it could not obtain evidence supporting the validity of its inventory valuation for the year ended December 2025.

The catch: Hamai is also changing how it grades slow-moving inventory as part of the correction, meaning the restated profit figures reflect a different valuation method, not just fixed errors, for stock counts going back five years.

REVOLUTION Misses Earnings Deadline Again as Its Auditor Still Won't Sign Off

REVOLUTION CO.,LTD. (TSE Standard: 8894) said it will not publish its third-quarter results for the year ending October 2026 on schedule because its auditor, Aria Audit Corporation, cannot finish an interim review within the required 45 days of quarter-end. Aria has withheld a conclusion since June, the latest turn in a nine-month standoff over how a batch of property-linked funds should have been recorded. An internal investigation found 28 of 251 affiliated property funds were wrongly booked as real estate deals rather than financial ones, pushing the small-cap real estate group toward correcting two years of past filings.

What to watch: A second missed deadline with the same unresolved auditor dispute raises the odds the eventual correction runs deeper than two years.

Deals and Defense Wins

Kakaku.com Bidder Raises Tender Price to ¥3,680, Pushes Deadline to September 29

Kamgras 1, the bidder taking price-comparison site operator Kakaku.com private, raised its tender offer price for the fourth time on September 10, lifting it to ¥3,680 a share from ¥3,571 and pushing the deadline back three weeks to September 29, 95 business days since the offer opened on May 13. The new price clears the ¥3,640 floor that holdout investor Oasis said it needed to tender.

Why it matters: Digital Garage and KDDI's combined 38% stake stays out of the tender itself under separate non-tender and buyback agreements tied to a later squeeze-out, so the fourth price rise is aimed squarely at getting Oasis inside the tender rather than forcing a contested vote afterward.

Beat Holdings Puts a 272.7% Dilution Vote to Shareholders, and Its Own Board Won't Back It

Beat Holdings Limited (TSE Standard: 9399), a Cayman-incorporated bitcoin-treasury company, will hold an extraordinary general meeting on November 24 in Tokyo to vote on two shareholder-proposed transactions, a debt-equity swap and a warrant issue, from its own 22.91% holder. The proposals could dilute existing owners by up to 272.7%.

The catch: The board says it cannot judge whether the terms are fair, yet it is letting the vote proceed anyway, leaving the fairness call entirely to shareholders facing a near-threefold dilution.

Terra Drone Alone Clears Japan's First Interceptor-Drone Mass-Production Trial

Terra Drone Corporation was the only company, out of 38 applicants, to pass Japan's first interceptor-drone acquisition trial and sign a mass-production contract under the country's Acquisition, Technology & Logistics Agency. The agency selected four companies, Terra Drone included, to supply demonstration units for the trial; the other three were foreign manufacturers. Only Terra Drone's TerraB1 model passed testing, clearing the way for delivery to the Maritime Self-Defense Force.

Why it matters: The contract win came alongside a widened first-half operating loss of ¥819mn and a new Tokyo-based subsidiary built to run the defense business, so Terra Drone now has a domestic-defense foothold even as its core drone operations still lose money.

On Our Radar

Otsuka's Taiho Unit Posts a Six-Month Survival Gain for a Rare Lung-Cancer Mutation

Otsuka Holdings' cancer unit, Taiho Pharmaceutical, said its Phase 3 REZILIENT3 trial of zipalertinib, combined with platinum-based chemotherapy, extended median progression-free survival to 14.5 months versus 8.5 months for chemotherapy alone in non-small-cell lung cancer patients with EGFR exon 20 insertion mutations, a hazard ratio of 0.50 (95% confidence interval 0.34-0.73, P=0.00015).

What to watch: Zipalertinib is approved nowhere yet, and Otsuka left its current profit forecast unchanged despite calling the drug a future growth driver, so the read-through for earnings depends on a regulatory filing that hasn't happened.

FSA Drafts New Tagging Rules for Japan's Mandatory Sustainability Disclosures

Japan's Financial Services Agency published on September 11 its draft annual update to the EDINET taxonomy, the XBRL tagging framework companies use to file disclosures. This year's draft creates a standalone sustainability-related taxonomy, built on the IFRS Foundation's own sustainability tags, for the disclosures companies must start filing under Japan's new Sustainability Disclosure Standards.

Why it matters: Public comments are due October 13, and the new tags become mandatory for reports covering the year to March 2027, giving compliance teams a tight window to build machine-readable reporting systems around a still-draft standard.
