In March 2026, global investment firm KKR announced a ¥528.56 billion (about $3.3 billion) tender offer for Taiyo Holdings, a 78-year-old, family-founded maker of electronic materials. Taiyo has been best known as the world’s top supplier of solder resist for printed circuit boards. Looking at the investor, it is easy to guess that the goal of the deal is to grow the company on the public market. The goal, however, is to take Taiyo Holdings entirely off the public market.

Taiyo Holdings has traded on the Tokyo Stock Exchange since 2001. Going private means walking away from public liquidity, public visibility, and the market discipline that comes with being listed. For a founding family that has watched over the company for three generations, agreeing to hand the keys to a New York-based private equity firm is a significant act of trust.

While many people may wonder why KKR wants Taiyo, I will look at this deal from the opposite perspective: why did Taiyo’s family, board, and largest shareholders trust KKR enough to say “yes”?

Trust Built Over Twenty Years

KKR has been investing in Japan for two decades, with more than $20 billion in assets under management in the country and a portfolio that includes KOKUSAI ELECTRIC, Bushu Pharma, Topcon, FUJI SOFT, and LOGISTEED. It is not a foreign fund parachuting in for a single opportunistic deal. It is a firm with an established Japanese branch which has a public history of how it has handled Japanese companies before. Even more importantly, it presents a visible pattern that Japanese boards and founding families could study before ever sitting down at the table.

In Japan, it is more important than almost anywhere else. Trust in Japanese business relationships is never extended on the strength of a pitch deck. It tends to accumulate slowly, through repeated, consistent behavior observed over years. KKR didn’t need to convince Taiyo’s stakeholders that it understood Japanese business culture in the meeting room because it had already been doing that for twenty years in full view of the same market which it was now asking to trust it with one of its own.

The Basis of Trust

Taiyo’s own language with regard to the deal reflects this. The company’s leadership has described KKR’s focus on employee ownership as closely aligned with Taiyo’s own long-held culture of partnership, which is a recognition of shared values rather than a concession being made to a foreign acquirer. That framing describes a foreign firm, a potential partner that has spent two decades proving, case by case, that “long-term partner” is not just a phrase it uses in deal announcements.

The moment a deal gets busy, foreign companies tend to forget this characteristic of Japanese business culture: long-term commitment and employee retention are often a core part of the negotiation. A structure that protects employee ownership and offers a multi-year horizon will do more to earn trust than almost any financial term on the table. It is a point worth revisiting on every engagement with a Japanese partner, not just the first one.

Shareholder Activism

Although this may look like a standard “foreign capital buys undervalued Japanese company” case, the real story is more layered and complex.

Currently, Japan’s public companies are under more external pressure to move quickly and engage more visibly than at almost any point in recent memory. The Tokyo Stock Exchange has been pushing listed companies to disclose their cost of capital and improve capital efficiency. Public activist campaigns in Japan rose sharply in 2025, making it one of the most active markets globally for shareholder activism outside the US. For many listed Japanese companies, the direction today is toward more stakeholder engagement, more disclosure, more public defense of strategy, more responsiveness to outside voices.

Taiyo has been in the middle of the wave of shareholder activism sweeping Japan. Among the shareholders whose support made the KKR deal possible is Oasis Management, a Hong Kong-based hedge fund and one of the most active shareholder activists in the Japanese market. Before this deal, Oasis had been publicly pushing back against Taiyo’s board, campaigning for shareholders to vote out two directors and pressing its own governance-reform proposals, citing concerns over the company’s governance and performance. Taiyo’s general public shareholder base is substantial too, at roughly 29.4% of shares outstanding, which is part of why getting board, family, and major-shareholder alignment mattered so much for the deal to succeed.

The Resolution

As a company already engaged in public, with an activist investor, instead of fighting the campaign to a standstill or giving in to Oasis’s governance demands, Taiyo – in a typical Japanese fashion – has converted the adversarial relationship into a shared exit. Oasis’s shares which the fund used to exercise pressure over Taiyo’s board now support the transaction which will remove that pressure.

This transaction reframes what “trust” means in this deal. It wasn’t only the trust a founding family extended to a foreign private equity firm with two decades of local history. In effect, it was also a negotiated peace between the company and a foreign activist. This is a deal where KKR’s structure and willingness to let the family reinvest and preserve employee ownership, has given Oasis a resolution it can support rather than continue contesting.

There’s also another layer here. While non-Japanese observers may feel the temptation to describe this move entirely as “going private to move faster” there is more to what meets the eye. Japanese organizational decision-making is deliberately unhurried by design. Organizations build consensus gradually and examine risk from every angle before they commit. That process doesn’t disappear just because a company delists. 

What changes is that the company is no longer required to justify that pace, quarter after quarter, to shareholders operating on a different clock. Privatization here isn’t an escape from having to change. Rather, it is a way of bringing a live external conflict to a resolution on terms the company can live with, and then returning to its own rhythm once the resolution is in place.

What This Means If You’re Working With a Japanese Partner

There are three main takeaways that carry beyond this specific deal.

First, if you’re a foreign company hoping to build trust with a Japanese counterpart — whether in an acquisition, a joint venture, or a long-term supply relationship — don’t expect a single strong pitch to do the work that only a strong record can do. Trust in Japan is compounded interest, not a lump-sum payment.

Second, when a Japanese partner seems to be moving slowly, or resisting a structure that would expose them to more external scrutiny, it is not necessarily resistance to change and lack of transparencey. It can be a preference to keep the process of change internal and carefully sequenced, rather than an attempt to avoid change and transparency altogether. Taiyo Holdings’ long-term management plan ‘Beyond Imagination 2030’ includes “working to develop opportunities arising from the expansion of generative artificial intelligence, data centers and communications infrastructure.” This makes the “company is resisting change” conclusion invalid and points to another one, that Taiyo is chosing the conditions under which the change will happen. 

Third, Oasis entered this situation pushing for governance change on its own terms: new directors, reform proposals, public pressure. It has gotten none of that. Instead, it’s got a going-private transaction it could support, on terms shaped far more by Taiyo’s own values of employee ownership, family continuity, long-term partnership, than by the activist’s original demands. The outcome is positive for everyone involved, and yet it isn’t the outcome Oasis set out to create.

Worth Remembering

That’s a pattern worth remembering by anyone entering a market that isn’t their own. In Japan in particular, conflict seldom delivers what its instigator imagined it would because the parties who shape outcomes are rarely the ones pushing hardest for their own terms. Those who manage to shape outcomes are the ones willing to adapt to what the other side actually values. KKR didn’t ask Taiyo to become more like a Western PE target but won its trust by speaking in terms Taiyo already recognized. That, more than the price tag, may be the real lesson of this deal for any company hoping to enter a market on someone else’s home ground.
