3D Investment Partners Pushes Past 10% of J. Front, Puts Board Seats on the Table

3D Investment Partners Pushes Past 10% of J. Front Retailing, Reserves Right to Demand Board Changes
3D Investment Partners Pte. Ltd., the Singapore-based fund run by director Sai Fai Yip, has pushed its stake in J. Front Retailing past the 10% mark and shifted the stated purpose of its holding from pure investment toward engagement. The fund filed Change Report No.4 with the Kanto Local Finance Bureau on September 7, triggered both by a rise of more than one percentage point in its holding and by that change in purpose. J. Front's own same-day notice on the shift in its major shareholder register puts 3D's position at 11.18% on a voting-rights basis.
What changed: The purpose language is no longer boilerplate. 3D's filing now reserves the right to make statutory 'important proposals' — the formal mechanism under Japan's large-shareholding rules for pushing board composition changes, asset disposals, business transfers, or a dividend overhaul.
Why it matters: J. Front, the department-store operator behind Daimaru Matsuzakaya and Parco, has spent years fielding questions about capital efficiency. A shareholder above 10% with an explicit mandate to propose board changes is a materially different owner than a passive index fund.
What to watch: Whether 3D follows through with a formal shareholder proposal ahead of J. Front's next annual meeting, and how the board responds to an owner now large enough to make demands stick.

Activist Playbook, Round Two

Oasis Management Lifts en inc. Stake to 13.45% and Adds Delisting to Its Demands
Oasis Management's stake in en inc., the Tokyo-listed recruitment and HR-services company, has climbed to 13.45% from 12.41%, per the Cayman fund's sixth change report on the position. Oasis holds 6,687,539 of en inc.'s 49,716,000 shares outstanding as of August 31, funded entirely with fund money rather than the manager's own capital or borrowings — a cumulative outlay of ¥10.28bn.
The catch: Oasis has already proposed delisting the shares and a capital-policy change that could hand a third party majority control, and it has reserved a broader agenda — including a possible move to dismiss the representative director — for the next 12 months.

Digital Hearts Chairman Bids ¥1,060 a Share to Take the Company Private
Digital Hearts Holdings, the Tokyo Stock Exchange Prime-listed video-game testing and quality-assurance group, disclosed a large-shareholding change report whose real subject is a buyout. Chairman Eiichi Miyazawa and his holding vehicle, A-1 Godo Kaisha, jointly hold 45% of the company, and Miyazawa's own bidding entity is now offering ¥1,060 a share for outstanding stock.
The catch: The tender doesn't carve out all of the chairman's holdings. It excludes only Miyazawa's own 8,925,633 shares and treasury stock — Miyazawa will still tender 500,000 of his shares and A-1 will tender all 1,324,900 of its shares into the offer, which closes September 24, 2026.

Restructuring and Retail Consolidation

TSE Approves Crasus Chemical Listing, Clearing the Path for Resonac's Petrochemicals Spin-Off
Resonac Holdings has cleared a listing condition on its planned spin-off. On September 7, the Tokyo Stock Exchange approved the listing of Crasus Chemical, the petrochemicals subsidiary Resonac's board voted on August 25 to spin off, on the TSE Standard market.
What changed: with that approval in hand, the separation remains on track for October 1, when Resonac shareholders as of September 30 will receive one new Crasus share for every Resonac share they hold.
Why it matters: TSE approval not being withdrawn is one of the conditions attached to the spin-off's effectiveness, and the petrochemicals business comes off Resonac's consolidated books once the split closes.

Shimamura to Absorb 21 Stores From a Sumitomo-Owned Supermarket Chain, Price Withheld
Shimamura Co., the Tokyo Stock Exchange Prime-listed apparel discounter, told the exchange on September 7 that its board resolved a day earlier to take over the assets and site rights of 21 stores currently run by a separate retailer as an apparel business, and to reopen them as Shimamura outlets.
What changed: the 21 stores, previously run by a Sumitomo Corporation-owned supermarket operator, will convert to Shimamura outlets between January and March 2027.
The catch: Shimamura has not disclosed the price paid for the deal.
Nippon Paper to Close Hungarian EV-Battery Materials Plant by End of 2026
Nippon Paper Industries has decided to cease operations at its Hungarian subsidiary, Nippon Paper Chemicals Europe, by December 31, 2026. The plant began local production in 2025, making a lithium-ion battery chemical called SUNROSE MAC.
What changed: the company will book roughly ¥5bn in special losses, mainly fixed-asset impairment, in the year ending March 2027, though it warns the figure is a current estimate that could still move as accounting procedures continue.
Why it matters: Nippon Paper blames shifting European and US EV subsidies and rules for killing the plant's economics.
