About

A Tokyo-based advisory firm dedicated to family legacies.

A Tokyo-based advisory and planning firm. We work exclusively with a select number of UHNW families in Japan committed to long-term legacy across wealth, education, and shared experience.

Conflict-free and advisory-only — no commissions, no product sales, no execution. The founding partner serves clients directly, ensuring discretion, continuity, and a single point of accountability.

Full bilingual capability in English and Japanese — seamless advisory across cross-border interests, from London properties to UK boarding schools to European family travel, all through one trusted relationship.

The Legacy Framework

Three pillars. One framework for generational continuity.

The strategies that create wealth are not the strategies that protect it.

In the accumulation phase, risk is a tool. In the preservation phase, it becomes a liability. Families that fail to make this transition — deliberately, structurally — are the ones that lose what took generations to build.

The failure is almost always traceable to three points: wealth that wasn’t repositioned for preservation, heirs who weren’t equipped to manage it, and heirs who never felt it was theirs to protect.

We address all three. Simultaneously.

I

Wealth Protection

Rigorous analysis of every investment that crosses your desk — fixed assets, cross-border opportunities, and the bespoke structured products banks bring to clients at this level. Our role is to prevent capital erosion through disciplined, unconflicted evaluation — preserving the foundation that funds education, family experiences, and the heir’s future.

  • Analysis of investments brought to us
  • Quality, risk, and suitability assessment
  • Coverage across Japan and English-speaking markets
II

Quality Education

We design the heir’s full educational journey — from international schools in Japan through to boarding schools and universities across the UK, US, Canada, and Europe. Every step is chosen to build the judgment, capability, and character required to steward wealth responsibly.

  • International school selection
  • Long-term educational strategy
III

Family Experiences

Frameworks and sample itineraries for meaningful family travel; vetted partners handle execution. Shared experiences from an early age build the values and bonds that move the heir to carry the legacy forward.

  • Sample trip frameworks and itineraries
  • Destination-based planning
  • Vetted travel partner referrals

Frequently Asked Questions

Before you reach out.

Who do you typically work with?

Tokyo-based HNW and UHNW families in Japan committed to long-term legacy planning across wealth, education, and shared family experience. We deliberately serve a limited number of families at any one time.

Do you manage investments?

No. Capital K is advisory-only. We do not execute trades, sell products, or accept commissions. We provide independent analysis and counsel on the quality, risk, and suitability of investments our clients are evaluating.

Do you work internationally?

Yes. Full bilingual capability in English and Japanese enables seamless advisory across cross-border interests — from properties in London to boarding schools in the UK and family travel in Europe — all managed through one trusted relationship.

Project-based or retainer-based?

Primarily retainer-based. Legacy planning is multi-generational by nature and is most effective within an ongoing relationship. Specific terms are discussed during a confidential introductory meeting.

Can you advise on UK boarding schools?

Yes. Educational pathway design for the heir is a core service. We help families think through options across international schools in Japan and boarding schools and universities in the UK, US, Canada, and Europe — with the long view in mind.
