Background & Biography
Kano completed graduate studies at the University of Tokyo’s Graduate School of Engineering before working at Goldman Sachs. A bitFlyer account of his early career describes settlement-system engineering followed by derivatives and convertible-bond trading. That combination provides a practical background for exchange-building: transaction processing and market risk are connected problems, even when they are handled by different teams. He co-founded bitFlyer, Inc. in January 2014, starting a business that would place those disciplines alongside the emerging demands of cryptocurrency custody and trading.
The company’s history records the launch of bitFlyer Lightning in July 2015 and the announcement of its original Miyabi blockchain in December 2016. International expansion followed. bitFlyer announced its planned US exchange launch in August 2017, while Reuters reported the launch of a European exchange in January 2018. In that interview, Kano welcomed regulatory engagement and acknowledged the risks of cryptocurrency trading, particularly when leverage was involved. The historical record therefore shows both a trading-platform founder and an executive concerned with the conditions under which the business could expand.
Today, the holding company is a distinct entity established in October 2018 and headquartered in Tokyo. Kano is its Representative Director & CEO; his current biography separately lists representative-director roles at bitFlyer, Inc. and bitFlyer Blockchain, Inc., plus directorships at bitFlyer USA, Inc. and Custodiem, Inc. These distinctions matter because group strategy, domestic exchange operations, technology development and overseas services carry different responsibilities. They also prevent an older executive title at one subsidiary from being mistaken for his present position across the group.
Notable Contributions
Kano’s most tangible contribution is the institution he helped build. bitFlyer developed beyond a single route for buying bitcoin into a group with exchange and blockchain businesses. The corporate timeline includes Japan’s exchange registration in September 2017, a later Type I financial-instruments business registration and the April 2024 launch of bitFlyer Crypto CFD. These milestones describe an expanding operating platform; they do not establish that every product is suitable for every customer or available in every jurisdiction.
Miyabi represents the engineering side of that development. Its technical documentation describes a permissioned, consortium-based blockchain using known participants and the BFK2 consensus algorithm. It supports smart contracts and digital-asset functions, with finality dependent on the documented fault assumptions. A concrete application came from Mitsui & Co. Digital Commodities, whose February 2022 announcement identified Miyabi as the underlying blockchain for Zipangcoin’s issuance system. Zipangcoin was designed to broadly track gold prices. This is a specific enterprise deployment, rather than evidence that Kano personally created every component or that the technology is universally superior to other systems.
The group’s institutional ambitions became clearer when bitFlyer Holdings completed the acquisition of all FTX Japan shares in July 2024. The acquired company was subsequently renamed Custodiem. The announced strategy involved a new custody business and possible services connected with spot crypto-asset ETFs, subject to the necessary Japanese legal framework. The current Holdings custody page still describes preparations for institutional and corporate services. The acquisition and renaming are completed events; the proposed business capabilities require separate evidence of launch.
A further direction appeared in April 2026, when Holdings announced an AI Strategy Office reporting directly to the CEO, established on April 1. Its remit includes internal productivity, research at the intersection of AI and blockchain, and financial infrastructure for AI agents. That is a concrete organizational decision with a research agenda. It does not, by itself, demonstrate a working autonomous-payment system, commercial adoption or a new revenue stream.
Why Katharos.ai Follows Yuzo Kano
Kano occupies a useful intersection between operators and rule-makers. The Japan Blockchain Association lists him as its representative director, while his company biography records his role among the founders of the exchange self-regulatory association established in 2018, now known as JVCEA. JBA and JVCEA are separate organizations. His participation offers a way to study how businesses try to shape the environment in which they operate, without treating an industry association as a government authority.
One specific example is JBA’s July 2025 submission for fiscal 2026 tax reform. It requested separate taxation at 20.315% for qualifying individual crypto gains and three-year loss carryforwards, with related changes for derivatives and account-based withholding options. These were advocacy requests, not a statement of enacted tax treatment. Katharos.ai follows the relationship between such proposals, subsequent official decisions and their practical consequences for users. Kano’s exchange interests make that relationship commercially relevant as well as politically interesting: the strongest reporting considers who benefits, what protections accompany a change and which responsibilities remain with intermediaries.
Areas to Follow
- Institutional custody: Track Custodiem’s transition from acquisition and preparation to clearly documented services, customer eligibility and operational responsibilities. Announcements should be matched with evidence that the relevant offering is actually available. - Enterprise deployments: Follow identifiable Miyabi customers and applications, including how permissions, governance and fault assumptions work in practice. A deployment is more informative than an isolated throughput headline. - AI research becoming products: Watch what the AI Strategy Office releases, which tasks it addresses and whether external users can test the results. Staffing and research commitments are early indicators, not proof of adoption. - Policy implementation: Compare association submissions with government publications and effective dates. Changes to taxation, market conduct or investment-product access should be reported at their actual stage of development. - Cross-border operations: Assess developments at the Japanese, US and European entities individually. Licensing, eligible customers and supported products cannot be inferred from the reach of the bitFlyer brand alone.
Reporting Scope
This profile covers Kano’s public professional record: company-building, disclosed executive responsibilities, enterprise technology and documented industry advocacy. Official biographies and announcements anchor roles and dates; independent Reuters reporting corroborates his part in international expansion. Technical descriptions are drawn from Miyabi’s own documentation and its customer’s announcement, with their limits preserved. Company history is not the same thing as an independent assessment of performance.
Coverage should keep the individual, the holding company, operating subsidiaries and trade associations distinct. It should also separate corporate decisions from statements made in an advocacy capacity. Plans for future custody services, tax requests and AI research should retain their conditional language until implementation is established. This approach makes it possible to examine influence without treating access to policymakers as proof of policy success, or an executive’s stated ambitions as completed achievements.
Areas of Influence
Exchanges & Infrastructure is Kano’s central category, reflecting the relationship between trading services, asset safekeeping and enterprise blockchain systems. Investment & Founders captures his role in building bitFlyer and directing a group that has used acquisition to pursue a broader infrastructure strategy. Policy & Regulation reflects his association leadership and participation in debates about how Japan’s digital-asset market should work.
Together, these categories describe influence through institutions rather than a single token or protocol. Kano is relevant to readers following the evolution of Japanese crypto businesses into more diversified financial-service providers. The durable test is whether those institutions deliver usable technology, clear accountability and services that meet the requirements of their intended customers. Katharos.ai follows that test through documented decisions and observable results.
