Who bids for Japanese companies, explained

How to read the markers. [D] — verified from a source retrieved for this note, listed under Sources. [I] — industry-understood; not formally disclosed by a named party. [S] — our own inference or judgment. Every figure is either sourced or marked as an estimate.

The short version

When a Japanese listed company is “in play”, the buyers and the price-setters are a small, repeating cast. Four kinds of fund do the work. Activists (Oasis, Elliott, 3D, Effissimo, Palliser, Strategic Capital, the Murakami family’s vehicles) take stakes of 5% to 20%, publish letters and, increasingly, refuse to sell into a bid they judge too low — which is how Toyota Industries’ buyout price went from ¥16,300 to ¥20,600 and Mandom’s from ¥1,960 to ¥3,105. Engagement funds (Dalton’s Nippon Active Value Fund, Silchester, ValueAct, Symphony) do the same job quietly, through 5% filings and shareholder proposals. Event-driven holders such as Farallon build blocks and sign tender agreements that decide who wins. And buyout sponsors make the actual offers: the foreign group (Bain, KKR, EQT, Blackstone, Carlyle, and since 2026 Warburg Pincus and Lone Star) for the large take-privates; the domestic group (Japan Industrial Partners, Polaris, Advantage Partners, J-STAR, NSSK) for carve-outs and management buyouts. [D for the names and prices; S for the grouping]

Two facts about the cast are easy to get wrong. The Bain that bids in Japan is a Japanese entity, Bain Capital (Japan), LLC — renamed from Bain Capital Private Equity Japan, LLC on 1 April 2025, with a Tokyo office since 2006 under Yuji Sugimoto, and a self-described 50-plus investment professionals — not “Bain Capital” the Boston firm acting from abroad. [D — Bain Capital Japan site] And the government is now a fifth participant: in 2026 it told MBK Partners to drop its bid for Makino Milling Machine on dual-use security grounds, and Makino then rejected a rival domestic bidder, NSSK, because NSSK’s own backers included foreign co-investors.

This piece is the companion to The Japanese tender offer, explained, which covers the rules a bid runs on. Here the subject is the bidders.

1. Four kinds of bidder, and a gate

The useful way to sort the funds is by what they do once they own shares, not by where they are based.

• Activists hold 5–20%, write public letters, run “vote against” campaigns, and in a contest refuse to tender below their own number.
• Engagement funds hold 5–25%, file the same disclosure, but negotiate privately and use shareholder proposals rather than press releases.
• Event-driven holders build a block ahead of, or during, a take-private and sign a tender agreement with the bidder they prefer. They rarely say anything in public.
• Buyout sponsors make the offer: a tender offer for all shares, a management buyout (MBO) with the target’s own president, or a recapitalisation that ends in a delisting.
• The gate is the Foreign Exchange and Foreign Trade Act screening. It did not exist as a live constraint in most 2024 contests; in 2026 it decided one.

2. The activists who set the price

Oasis Management (Hong Kong; founder Seth Fischer) is the most active name in 2026 filings. It held about 19.5% of Kakaku.com and told both bidders it would not tender below ¥3,640 a share, above EQT’s live ¥3,570 offer; its tender agreement with the rival Bain–LY Corporation consortium had already expired. [D — Investing.com, corroborated by the Oasis release summarised there] At SMS it ran a campaign against the reappointment of the president and one director from an 18.3% stake. [I — Yahoo Finance] At Dentsu Soken it took about 5% roughly a week before Itochu announced a ¥2,880-a-share offer for the shares it did not already own. [I — Investing.com] The pattern is the same each time: a double-digit stake, a public number, and a refusal to sell below it.

Elliott Management ran the largest activist intervention of the two years. Holding 7.1% of Toyota Industries, it published a statement on 18 January 2026 opposing Toyota Fudosan’s revised ¥18,800 take-private price and putting the company’s net asset value at ¥26,134 a share. The final price was ¥20,600, up from the original ¥16,300, and Elliott tendered. [D — Elliott’s own release; a second outlet for the final price] Elliott also disclosed 5.03% of Tokyo Gas and pressed it to sell real estate, which the company then earmarked for sale [I — Mingtiandi], and engaged Sumitomo Realty on returns and cross-shareholdings, though the stake size was not disclosed in the report retrieved. [I — MarketScreener]

3D Investment Partners (Singapore; founder Kanya Hasegawa) runs multi-year campaigns. Its February 2025 Sapporo presentation, from a roughly 5% stake, asked for a tax-qualified spin-off of the real-estate holding company and a new outside director. [D — 3D’s own presentation] It filed 5.10% of J. Front Retailing in June 2026 and 5.03% of Casio in April 2026. [I — filing reports] In the 2024–25 Fuji Soft contest 3D and Farallon signed tender agreements with KKR — see the tender-offer explainer.

Effissimo Capital Management (Singapore) builds very large blocks over years. It held 9.89% of Toshiba as its largest shareholder when it agreed to tender into the JIP consortium’s ¥4,620 offer in 2023 [D — two reports agree], and raised UACJ from 21.22% to 22.23% in April 2025. [I — filing report]

Palliser Capital (London; founder James Smith, formerly of Elliott) works with stakes just above 4–5% and a specific thesis. At Keisei Electric Railway it proposed four outside directors from a stake “in excess of 4.5%” in 2025 [I — campaign coverage]; at Toto in February 2026 it argued the ceramics business is an under-valued AI-materials asset and asked for cross-shareholding sales, from a top-20 holding. [I — two reports]

Strategic Capital (Tokyo; Tsuyoshi Maruki) runs a proposal season every year. Its April 2026 release at Sanyo Denki, from a combined stake of about 16%, made six proposals: Maruki as a director, one-year board terms, a nomination committee, an annual capital-policy debate, and a 5-for-1 stock split. The committee proposal was withdrawn after the company set one up itself. [D — Strategic Capital’s own release]

The Murakami family’s vehicles (City Index Eleventh; Aya Nomura as named holder) file across a fast-rotating basket. In May 2026 they disclosed 5.86% of Air Water with language reserving the right to propose “an MBO including delisting”. [D — Reuters Japan] At Mandom, Aya Nomura’s stake of more than 20% forced CVC’s management-buyout price from ¥1,960 to ¥3,105 and saw off a KKR counter-bid before the tender closed on 26 February 2026 with about 72% of shares tendered.

3. The quiet engagement funds

Dalton Investments and Nippon Active Value Fund (NAVF) work as one: Dalton’s Tokyo research team (in Tokyo since 2000, with a marketing team added in 2024) manages the stakes, and Rising Sun Management voices them. [D — Dalton’s own release] In 2025 NAVF put a twelve-director slate to Fuji Media Holdings’ 25 June AGM with a “Renaissance of Fuji Television” charter; the board opposed it. [D — NAVF’s own statements] In 2026 the board of Ebara Jitsugyo rejected all three NAVF proposals on pay and buybacks before its 24 March AGM [I — TipRanks], and the group raised Noritz from 8.58% to 9.60% in May. [I — MarketScreener]

Silchester International Investors (UK) says nothing in public; its intent appears only in the “purpose” field of its filings. In August 2026 it disclosed a new 5.06% of Miura, built between 22 June and 20 August for about ¥19.97bn, with a purpose covering dividends, buybacks and governance. [I — ad-hoc-news] It is at the same time cutting older industrial holdings.

ValueAct Capital (San Francisco) takes board seats rather than campaigning — until it is refused. At Seven & i’s 25 May 2026 AGM all four of its nominees were voted down and the CEO was re-elected with 76.36% support; ValueAct’s stake was 4.4%. [I — CSP Daily News; source not retrieved this run]

Symphony Financial Partners (Singapore filer) is the slowest builder of all: its Infomart stake went from 22.95% in September 2025 to 24.86% in December 2025 through repeated filings, with no public ask recorded. [D — M&A Online filing log]

4. Event-driven blocks: Farallon

Farallon Capital does not campaign; it positions. In the Fuji Soft contest it signed a tender agreement with KKR alongside 3D, which is what let KKR clear the first stage. At Nikkon Holdings it raised its stake to 24.65% of the voting rights in March 2026, enough for Nikkon to reclassify it as an “other affiliated company”. [D — Nikkon notice via TipRanks] A holder that size decides whether a discounted take-private can work; the sponsors bidding for Nikkon in September 2026 (section 5) know that. No retrieved source says what Farallon has agreed with either of them.

---

5. The foreign sponsors

The large take-privates of the last two years were made by six foreign firms, two of which arrived in the market in 2025–26.

Three things stand out. First, contests are now the norm at the top end: Fuji Soft, TechnoPro, Mandom, Kakaku.com and Nikkon were all fought between two sponsors, and in three of the five an activist or a block-holder set the clearing price. Second, the price is negotiable downward as well as up: Bain’s eSOL MBO at ¥820 is below the ¥935 close before the announcement, and the Nikkon bidders are reported to be weighing a discounted offer after a 50% run-up — both rely on the pre-leak reference price argument covered in the tender-offer explainer. [I] Third, Apollo’s Nippon Sheet Glass deal shows a second route to control: a large share allotment and a debt-for-equity exchange, approved by shareholders, that ends in a delisting with no tender offer at all. [D]

6. The domestic sponsors

Domestic sponsors work the other end of the market: carve-outs from industrial parents, and MBOs with founders or presidents who stay on.

• Japan Industrial Partners (JIP), the firm that led the ¥2 trillion Toshiba take-private in 2023, launched a tender offer for Mitsubishi Logisnext on 30 September 2025 with a master agreement under which parent Mitsubishi Heavy Industries sells and reinvests. [I — PR Newswire]
• Polaris Capital Group: DD Group MBO with its president at ¥1,700 a share, about ¥28.3bn, July–August 2025. [I — MarketScreener]
• Advantage Partners: Nihon Chouzai tender offer, 31 July to 17 September 2025 [D — its own news page]; Furukawa Battery at ¥1,400, with the parent Furukawa Electric selling afterwards. [I — MLex]
• J-STAR: Nippon Concept tender via a purpose-built vehicle, “M Corporation”, from 30 June 2025. [D — its own release]
• NSSK: after MBK withdrew from Makino, NSSK proposed its own bid; Makino’s board rejected it on 1 August 2026, judging government approval unlikely because NSSK’s co-investors were foreign. [I — Nikkei Asia]
• Unison Capital bought Krispy Kreme Doughnut Japan from its US parent (agreement 19 December 2025, completed 2 March 2026) — an asset purchase, not a listed bid. [D — its own release] No Integral bid for a listed company was found in the window.

---

7. The gate: security screening decided a contest

Makino Milling Machine is the case to know. The government advised MBK Partners, a Seoul-based sponsor, to drop its bid because machine tools are dual-use technology. NSSK, a Tokyo sponsor, then proposed its own bid, and the target rejected that too, on the ground that NSSK’s foreign co-investors would face the same screening. [I — Nikkei Asia, two articles] For a foreign fund the lesson is not “domestic partners solve it”; it is that any foreign money in the bidding vehicle brings the review, and the target’s board can cite the review to refuse.

8. What this means for a reader of the NL2 or NL4 editions

• A price in a Japanese contest is set by three parties, not two: the bidder, the board’s special committee, and whichever activist or block-holder can deny the two-thirds squeeze-out vote. Read the 5% filings of Oasis, Farallon, Effissimo and the Murakami vehicles before reading the offer price.
• Foreign sponsors are Japanese businesses with Japanese names on the filings: BCJ-110, Kamgras 1, Lumina Japan Acquisition, Caron Holdings, M Corporation. Follow the vehicle, not the brand.
• The domestic sponsors are not a safe harbour from security screening if their funds include foreign LPs.
• Contests run longer than the 60-business-day tender-offer maximum suggests: Kakaku.com passed 85 business days; Mandom took eight extensions.

---

Caveats

• Kakaku.com is live. The last filing retrieved is 27 August 2026 (¥3,571, period to 10 September). Search results describe a further increase to ¥3,680 and an extension to 29 September, but the 10 September filing returned an error and no page carrying its content loaded; nothing after 27 August is asserted here.
• Dentsu Soken. Itochu’s own notice of 31 August 2026 gives ¥2,880 a share, a vehicle owned 80% by Itochu and 20% by IFP, and a launch aimed at early November after competition clearances; the ¥215.2bn total for the 38.2% not held by Dentsu Group is from Itochu’s announcement as reported. One report retrieved gives “about ¥250bn” without explaining the basis; it is not used.
• Farallon at Nikkon is 24.65% of voting rights on Nikkon’s own count as of 26 March 2026 and 23.00% on its large-shareholding filing; the two use different denominators.
• Fuji Soft’s final price, ¥9,850, is from the Reuters report cited in the tender-offer explainer; tonight’s retrieved recap gives the second tender’s opening price, ¥9,451, and the 57.92% result.
• Marked “source not retrieved”: Topcon, Fujitec, BPEA IX, TechnoPro, KFC Japan, CJP V, Sharingtechnology and the Seven & i vote came from search summaries of pages that returned errors on direct fetch (Blackstone, Business Wire, Japan Times, CSP Daily News). They are reported at [I], not [D], and none carries a URL below.
• Stakes and offices not found: no retrieved source gives a Tokyo office or assets figure for Oasis, Elliott, 3D or Effissimo; Palliser’s Japan Post position, Silchester’s Hakuhodo DY and Nikon filings, NAVF’s Myojo Engineering stake and Symphony’s other positions were not retrieved.
• The grouping in section 1 is ours. Several funds sit in two groups (Farallon signed tender agreements at Fuji Soft; Oasis took an event-driven stake at Dentsu Soken).
