Oasis Turns Up the Heat on Nidec — And Puts Delisting on the Table

Oasis lifts its Nidec stake to 7.97% and floats delisting and a board shake-up, while a Nagoya-listed firm gets an actual delisting date after its auditor refused to sign off — and Japan's record August exports still couldn't close a widening trade gap.

Oasis Lifts Nidec Stake to 7.97% and Puts Delisting, Board Control on the Table

Oasis Management has raised its stake in Nidec to 7.97%, up from 6.78% at its last filing, and used the update to spell out how far its campaign against the electric-motor and machinery maker now reaches.

What changed: The Cayman Islands-based activist fund's September 16 filing shows it holds 95,067,750 shares out of Nidec's 1,192,568,936 shares outstanding, held solely and without joint holders. The filing also renews a set of demands: new board directors, a delisting of Nidec from the Tokyo Stock Exchange, and a reworked capital policy.

Why it matters: Oasis has reserved the right to buy more than five additional percentage points of stock within roughly three months of the filing, a threshold that keeps the pressure compounding rather than plateauing at a single stake size.

What to watch: This filing does not show Nidec's response to the delisting or board proposals; the next marker is whether Oasis follows through on the additional purchase window it has kept open.

Oasis Management Raises SMS Stake to 26.97%, Puts Board Removals and Delisting on the Table

Oasis Management's SMS holding climbed to 26.97% from 25.93% in a filing that also formalizes proposals on director dismissals, asset sales, a business exit, and a possible delisting or change-of-control transaction, though the filing does not show SMS having agreed to or acted on any of them.

Nagoya Exchange Sets October 17 Delisting for ESPOIR After Auditor Refuses an Opinion

ESPOIR Co., Ltd. (3260, Nagoya Stock Exchange Next Market) will be delisted on October 17, the exchange said, after designating the stock "securities to be delisted" from September 16 through October 16. The exchange's stated grounds: the audit report attached to ESPOIR's financial statements carried a disclaimer of opinion, a finding the exchange treats as a threat to market order.

What to watch: Shares keep trading under the delisting flag for one more month before formal removal, leaving remaining holders a narrow window to exit.

Japan's Finance Minister Orders Review of Looser Business-Lending Rules for Growth Companies

Japan's financial services minister, Satsuki Katayama, has directed the Financial Council to study loosening regulation on money-lending businesses that lend to companies, aiming to widen the pool of funders available to growth firms and businesses restructuring their operations. The Financial Services Agency has published the agenda for the review panel's first meeting. What's on the table: A review of rules that currently constrain non-bank lenders, potentially opening room for private-credit and fintech players alongside conventional banks.

The catch: The mandate specifies no draft rules or timeline, so this is the start of a study, not a change in the law.

Japan's Labor Inspectors Flag Violations at Three-Quarters of Workplaces Hiring Foreign Trainees

Japan's labour inspectors are checking more workplaces that employ foreign technical trainees and specified skilled workers, and most of the workplaces they chose to inspect in 2025 failed the check.

The number: Of the workplaces labour inspectors examined — a group that includes sites already suspected of violations — roughly three in four had a rule violation, the Ministry of Health, Labour and Welfare said. That inspected-workplace rate is not a measure of every business that employs these workers, since inspectors target sites more likely to have problems.

Why it matters: Compliance risk for employers of foreign trainees runs wider than pay disputes, and inspection volume itself has been rising.

Eisai's Weekly Self-Injectable Leqembi Wins Japan Approval, Home Use Still Awaits Reimbursement Review

Eisai's newly approved subcutaneous Leqembi pen lets patients self-inject weekly at home instead of visiting a clinic every two weeks for IV infusion, but a Central Social Insurance Medical Council review and listing on the injectable drug list must happen first, and Eisai says the approval's effect on its coming-year earnings forecast is minor.
