We engage with investors, enterprises, and society alike — turning capital into enduring growth and the creation of value for the future.
Whiz Partners is an independent investment firm. The continued fulfillment of three promises — to investors, to portfolio companies, and to society — is the foundation of all that we do.
Engagement investing in listed companies, and private-equity investments that help shape industry structures from the ground up.
The methods differ; what runs throughout is dialogue and a willingness to roll up our sleeves alongside our partners.
Through dialogue and mutual understanding with management, we provide both capital and tireless support —
what we ultimately seek is sustainable growth driven by the portfolio company itself.
That is the essence of our work.
We do not pursue hostile shareholder proposals or seek control. Nor do we simply commit capital and wait for prices to rise. We step into the business itself and roll up our sleeves alongside management — our strength lies in this combination of grounded effort and deep expertise.
For small- and mid-cap listed companies, we provide a distinctive capital structure combining convertible bonds and warrants, supported by hands-on engagement inspired by venture-capital practice. Through business development, partnership formation, and M&A support, we work with our network to create the catalytic events that drive enterprise value creation — pursuing substantive enhancement of enterprise value.
PIPEs: Private Investment in Public Equity
In private companies, we engage from company creation through active participation in management. Examples include Axcelead, carved out of Takeda Pharmaceutical’s research division, and ARCALIS, a Japan–US joint venture established with Arcturus Therapeutics of the United States. We are both investors and industry builders.
From our network, we actively generate the key events that drive share-price appreciation and business-value creation.
We incorporate the lessons of every prior engagement, continually refining our investment design — pursuing repeatable, dependable execution.
From the Takeda carve-out to the domestic manufacturing of mRNA medicines, we believe in the possibility of investment that helps shape industry structures from the ground up.
The starting point for sound judgment and action. We hold an ethical perspective in every decision we make.
The duty to honor the trust placed in us. We respond to the trust of our investors with the highest degree of integrity.
The bedrock that supports unprecedented endeavor. We hold creativity as the source from which innovation arises.
The wellspring of trust both within and beyond the firm. We ensure transparency throughout our processes to build durable relationships.
Balancing these two priorities is central to our management philosophy.
Grounded in healthcare, AI, and digital transformation —
extending to industries where capital can drive growth and change.
Building on the strengths we have cultivated in healthcare, AI, and digital transformation, we extend our reach to every domain where capital can support the growth and transformation of industry.
Expertise, for us, is not fixed; it expands as industries evolve. Across every field, we invest through dialogue and a willingness to roll up our sleeves alongside our partners.
Axcelead and ARCALIS — two companies that began as ideas, neither of which we could have built alone.
With the support of many partners, we brought together talent and capital and helped build entire industries.
Our role is to originate the idea, connect the participants, and stay alongside them for the long term.
Through investment, we are privileged to take part in shaping Japan’s future.
Inheriting Takeda Pharmaceutical’s drug discovery platform, Axcelead became fully independent from Takeda in 2019 under our leadership. This is more than a CRO. Spanning target identification, lead optimization, and translation from preclinical to clinical stages, Axcelead serves as a Drug Discovery Orchestration Hub that integrates AI, data science, and wet-lab capability — standing at the center of Japan’s drug discovery ecosystem. More than 300 global clients place their trust in the company.
Conceived, structured, and brought to life with deep involvement from our firm, ARCALIS was established in 2021 as a joint venture between our platform company Axcelead and Arcturus Therapeutics of the United States. Operating from two sites in Minamisoma (Fukushima) and Kashiwa-no-ha (Chiba), ARCALIS has a track record of commercial-scale manufacturing of the COVID-19 vaccine “Kostaive.” By bridging Arcturus’s advanced mRNA technology, Australia-based CSL Seqirus’s global reach, and Meiji Seika Pharma’s domestic distribution, ARCALIS serves as an implementation hub for international collaboration — anchoring Japan’s economic security and the global mRNA supply network.

Former Director of Nomura Securities and President & CEO of Benesse Holdings.


Former Senior Executive Vice President of Matsushita Electric Industrial (now Panasonic) and former Vice Chairman of the Japan CFO Association.


Certified Public Accountant and Licensed Tax Accountant; formerly of PwC. A specialist in corporate valuation.

Former Member of the Board and Head of Finance at Toyota Motor; first President of Toyota Financial Services; former Chairman of Aioi Nissay Dowa Insurance.

Career at Nomura Securities. Joined Whiz Partners in 2011 and led marketing through 2020. As Assistant to the Chairman from 2026, supports both management and on-the-ground operations of the firm.
Since 2010, we have raised and managed seven funds, with one additional fund currently being raised and managed.
This page is provided for informational purposes only and is not intended as a recommendation of any specific transaction or as a solicitation of investment.
Past performance is not a guarantee of future investment results.
The table above lists only the investment limited partnerships that the firm has established since 2010.
Japan’s first integrated drug discovery platform, and one of Asia’s largest. The carve-out from Takeda Pharmaceutical was led by Whiz Partners.
The Asia-Pacific region’s first GMP-compliant commercial-scale mRNA drug substance and drug product manufacturing facility. Whiz Partners conceived and led the company’s formation from the ground up.
Note: the companies above are listed as their names appeared when our investment was publicly disclosed.
In 2010, the firm became independent following its separation from the CSK Group, and changed its name from “CSK Venture Capital” to “Whiz Partners.” At that time, the fund business was often viewed with suspicion as something profit-driven or socially suspect. As Toshio Ando (former Chairman of the Japan Securities Dealers Association) stepped down from public office to return to leadership in the private sector, he made this commitment:
The pursuit of investment performance and uncompromising compliance.
The simultaneous fulfillment of both — this is what gives meaning to our work. — Toshio Ando, Founder & Chairman
When the firm became independent, leaders who have stood at the forefront of industry and finance — including Hiroshi Okuda (former President of Toyota Motor and Chairman of Keidanren), and Hideto Ozaki (former Member of the Board and Head of Finance at Toyota Motor, first President of Toyota Financial Services, and former Chairman of Aioi Nissay Dowa Insurance) — stood with us from their independent perspectives. They did so because they believed that this firm was not merely an entity pursuing economic value, but one that could be trusted to uphold its responsibility to society, uphold the dignity expected of a responsible enterprise, and create new value.
That relationship of trust is the origin of who we are.
We aspire to be an organization that shares a strong ethical compass, sense of purpose, and accountability for return performance as a fund manager, and that can translate them into tangible outcomes.
Each of our directors and employees cherishes dignity, intellect, and sincerity, alongside a steadfast commitment to investment results, fulfilling their responsibilities and continuing the work of bringing our principles to life.
We hope to walk this path with those who share these values and can grow alongside us.
What we have aimed for is not a fund that pursues returns alone.
We seek to break through the sense of stagnation that has settled over Japan —
through finance.
And to support the growth of Japanese industry.
During the biotech winter affecting listed biotech ventures, we supplied PIPEs capital to enable investments that bridge the “valley of death.”
Through the carve-out from Takeda Pharmaceutical, we built Axcelead.
Through a Japan–US joint venture, we built ARCALIS and helped establish domestic manufacturing of mRNA therapeutics.
And the many themes still ahead — healthcare, AI, DX, defense, semiconductors, tourism, regional revitalization, education, culture, and beyond
— all rest on the foundation of the commitment we made at the time of our independence.
And together with the shareholders, fund investors, portfolio companies, partners — every stakeholder who shares this vision, our directors and employees will work together to help shape the future ahead.
That is our commitment.
