Message from CEO & Founder
We at Arcana Partners, Inc. believe in the potential of fintech and the underlying strength of financial institutions and major corporations, and we aim to contribute to the advancement of Japan’s financial infrastructure.
With rapid changes in the external environment—particularly the evolution of generative AI—the financial industry is entering a new era.
We support this transformation by serving as a bridge between startups and major financial institutions.
The bank where our CEO, Hoshino, began his career as a new graduate went bankrupt due to cash flow problems. During the crisis, he was responsible for cash flow management strategies utilizing the bank’s securities portfolio, and he learned the hard way just how thin the layer of risk capital is in Japan’s financial markets.
Since then, he has built his career driven by a desire to “strengthen Japan’s financial infrastructure,” including from the perspective of an external advocate for change.
We believe that the current rapid environmental changes actually present a valuable opportunity to fundamentally transform Japan’s financial infrastructure, which is why we decided to start this company.
The company name “Arkana” is a portmanteau of “Ark” (Noah’s Ark, a bridge to the future) and “ana” (Latin for “accumulation of wisdom”). It embodies our aspiration to serve as a bridge to the future of Japan’s financial sector by drawing on the collective wisdom of our clients and partners.
Leveraging our extensive experience in strategic consulting and our broad network of banks and international card brands, we stand alongside business leaders to address their various challenges and serve as partners in finding solutions.
As partners in shaping the future together, let’s create new value with us.
President & CEO
Mato Hoshino
