Jun 2018 — Present
Chief financial officer; executive director since June 2020
Yorihama Assurance
- Sector
- Commercial non-life insurance
- Ownership
- Privately held by long-term institutional shareholders
- Company scale
- JPY68bn gross written premium, year ended March 2026; premium is not accounting revenue
- Employees
- 960
- Geography
- Japan; nineteen offices and central teams
- Reporting to
- Chief executive; executive director from June 2020
- Team
- Sixty-eight finance colleagues; five direct reports
- Financial scope
- Finance accountability across JPY132bn assets at March 2026 and the insurer's reporting, planning and cash account
Mandate
Connect underwriting obligations, financial reporting and the resources required to honour the company's commitments.
Outcomes
- Collected JPY3.3bn from a defined JPY4.6bn overdue recovery cohort over fourteen months.
- Funded an eighteen-person service team after a JPY6.2bn-premium portfolio stopped renewing.
- Staged a JPY1.1bn proposed systems investment with JPY380m initially released.
- Kept a JPY2.4bn older-cohort claims revision separate from current underwriting performance.
Decisions in context
I became CFO after eight years leading financial control at Yorihama. The wider appointment brought responsibility for the financial consequences of decisions whose claims and service costs might extend well beyond the current plan. I lead sixty-eight colleagues through five direct reports and work alongside the heads of actuarial, claims, underwriting and technology. Their specialist decisions remain theirs. My executive directorship began in June 2020, two years after the CFO appointment, and is not an independent seat. I prepare management's financial account while participating in the board's consideration of the enterprise as a whole. The recovery programme and runoff plan made that dual responsibility tangible: I had to explain the cost of unfinished work and support resources for it when a simpler presentation would have looked more attractive. My present focus is the connection between older claim cohorts, recovery timing and the cash plan.
Reason for the move
Current executive appointment; considering one compatible external directorship.
Concurrent appointment
The executive directorship is part of the continuing CFO appointment, not a second employment role.
Jul 2010 — May 2018
Financial controller
Yorihama Assurance
- Sector
- Commercial property and liability insurance
- Ownership
- Private institutional ownership
- Company scale
- JPY43bn gross written premium in the final financial year of this role
- Employees
- 710 at the end of the appointment
- Geography
- Japan; fourteen offices at the end of the period
- Reporting to
- Chief financial officer
- Team
- Thirty-two reporting and financial-operations colleagues; four direct reports
- Financial scope
- Control and reporting for JPY84bn institutional assets at March 2018; no underwriting approval authority
Mandate
Make the insurer's reporting reconcilable across underwriting, claims, recoveries and the financial ledger.
Outcomes
- Established a monthly movement account separating claim payments from estimate changes.
- Reduced unresolved inter-system balance differences from 126 to nineteen during the first eighteen months.
- Created a common evidence pack for significant recovery balances.
Decisions in context
Joining Yorihama meant moving from a planning function into the responsibility for a complete financial control process. I managed thirty-two colleagues and reported to the CFO, with four managers coordinating the principal work streams. We brought claim, recovery and ledger movements into a shared reconciliation so that a difference could be traced to the originating record instead of circulated between departments. The reduction from 126 unresolved differences to nineteen described a control workload, not an equivalent reduction in monetary exposure. I learnt to present the value and cause beside the count. The role also taught me how to question an actuarial movement without presenting myself as its author. I prepared finance papers for senior review but did not hold a director's appointment during this period. Promotion to CFO followed a planned succession and widened my responsibility from explaining the account to supporting the company's major financial commitments.
Reason for the move
Promoted following the CFO's planned retirement.
Apr 2003 — Jun 2010
Manager, underwriting planning finance
Kanewara General Insurance
- Sector
- Commercial non-life insurance
- Ownership
- Privately held insurer
- Company scale
- JPY29bn gross written premium in the final full year of the appointment
- Employees
- 540
- Geography
- Japan; regional commercial insurance distribution
- Reporting to
- Head of corporate planning
- Team
- Eleven finance analysts; two team leads
- Financial scope
- Planning support for commercial portfolios representing JPY18bn gross annual premium near the end of the role
Mandate
Explain the financial development of underwriting portfolios without confusing premium volume with earnings quality.
Outcomes
- Introduced separate current-year and prior-year development views for six commercial portfolios.
- Added remaining-service costs to proposals for three portfolio changes.
- Reduced the quarterly planning preparation cycle from twenty-two to sixteen working days after two annual cycles.
Decisions in context
I led an eleven-person analytical team supporting underwriting plans, with two team leads helping coordinate recurring reviews. The portfolio premium figure describes the business we analysed; it was not revenue I personally generated or authority to accept risks. Underwriters owned selection and pricing, while planning finance examined the assumptions and the consequences for the institution. I introduced a clearer separation between business written in the current period and the later development of earlier commitments. That made it possible to discuss a stronger new book without hiding a difficult old one. I also began costing what remained after a portfolio change, including claims support and access to records. These were recommendations to senior management, not board decisions made by my team. Moving to Yorihama gave me the opportunity to connect this planning experience with the controls and reporting on which a broader finance appointment would depend.
Reason for the move
Moved to Yorihama for institution-wide financial control responsibility.
Apr 1996 — Mar 2003
Reinsurance accountant; settlement team supervisor from April 2000
Kanewara General Insurance
- Sector
- Property and casualty insurance
- Ownership
- Private domestic shareholders
- Company scale
- JPY17bn gross written premium in the final year of the role
- Employees
- 360
- Geography
- Japan; reinsurance counterparties in several markets
- Reporting to
- Reinsurance accounting manager
- Team
- Initially an individual contributor; supervised five settlement colleagues from April 2000
- Financial scope
- Preparation and follow-up of a JPY2.1bn recovery receivable account at March 2003
Mandate
Maintain recovery records and support settlement through complete, traceable documentation.
Outcomes
- Introduced a common record of documents required for material recoveries.
- Helped reduce files returned for missing references from forty-three to fourteen per quarter over one year.
- Supervised the monthly settlement schedule for five colleagues from April 2000.
Decisions in context
This role put the distance between an accounting asset and its collection into daily view. I prepared settlement records, followed missing references and worked with the reinsurance team on the status of larger items. I did not interpret contracts independently or agree a negotiated settlement. Those responsibilities stayed with the relevant specialists. From April 2000, I supervised five colleagues, making the quality of their preparation and review part of my own remit. We reduced files returned for missing references by recording the requirements before dispatch rather than correcting the same omissions afterwards. The JPY2.1 billion receivable account establishes the scale at the end of the appointment; it is not a claim that I collected that sum personally. The move to planning allowed me to ask why particular obligations had been accepted in the first place, while retaining the operational knowledge of what would later be required to settle them.
Reason for the move
Internal appointment to underwriting planning broadened the financial remit.
Concurrent appointment
Supervisory responsibility was added within the same reinsurance-accounting appointment in April 2000.
Apr 1990 — Mar 1996
Claims accounts assistant
Kanewara General Insurance
- Sector
- General insurance
- Ownership
- Privately held
- Company scale
- JPY10bn gross written premium near the end of the appointment
- Employees
- 240
- Geography
- Japan; central claims accounting support
- Reporting to
- Claims accounting supervisor
- Team
- Member of an eight-person team; no direct reports
- Financial scope
- Reconciliation support for approximately JPY420m monthly claims payments in the final year
Mandate
Match approved claims payments with records and raise unexplained differences for review.
Outcomes
- Maintained a dated log of unmatched payment references.
- Helped reduce the team's unresolved monthly reference queue from 170 to fifty-six over ten months.
- Prepared reconciliations for supervisor approval without settlement or payment-release authority.
Decisions in context
I started in a supervised accounting role after completing my degree. The team matched payments that claims colleagues had approved, investigated differences and prepared records for review. I had neither authority to decide coverage nor permission to release a payment independently. My useful contribution was often a careful question about a reference that did not agree. I learnt to distinguish a missing document from a disputed claim and to ask the person closest to the file before drawing a conclusion from the ledger. A dated reference log helped the team reduce its unresolved queue, but the improvement belonged to the group rather than to me alone. The monthly payment scale describes the environment late in the appointment, not a personal mandate. Moving into reinsurance accounting was a natural next step because it extended the same discipline to the recovery associated with an already paid claim.
Reason for the move
Selected for reinsurance accounting after developing a reliable claims-record practice.
What I am looking for next
I am looking for one external board contribution in an enterprise whose commitments last longer than its initial sale. Industrial service businesses, established insurance-service providers outside direct competition, or companies with substantial maintenance obligations could benefit from the questions I bring. I would want the chair to value careful examination of the cost still embedded in earlier decisions, alongside the ambition for new activity.
My current executive directorship gives me board experience from within management. An external non-executive appointment would require a different distance from daily operations, and I would discuss that transition explicitly. I can offer twenty days annually, subject to employer consent and a realistic provision for committee work, travel and exceptional events. I would review the company's relationship with Yorihama, its owners and its insurance arrangements before progressing. A credible contribution needs room for preparation and access to competent specialist advice. I am more interested in one role where I can remain engaged through difficult reporting periods than in accumulating appointments whose calendars I cannot responsibly support.
