In recent years, Japan's ultra-high-net-worth population has become an increasingly visible presence. Households holding net financial assets of 500 million yen or more — the threshold Japan uses to define "ultra-high-net-worth" — were estimated at roughly 118,000 as of 2023, according to an estimate published by Nomura Research Institute on February 13, 2025. Combined with the broader high-net-worth bracket, the total reaches 1.653 million households, with combined net financial assets of roughly 469 trillion yen, and the real estate industry has taken notice, with a growing amount of business now built specifically around ultra-high-net-worth clients. This article examines the distinctive features of real estate business aimed at this segment, and the shifts in client needs we have observed first-hand.
What do ultra-high-net-worth clients actually want from real estate, and how does that differ from the broader wealthy segment?
In short, ultra-high-net-worth clients care about more than simply owning an expensive property. They place real weight on the experience and status a property confers, and on long-term considerations such as preserving and passing on wealth across generations.
Interest runs high in scarce, high-value locations — prime addresses in Tokyo's Minato ward, or exceptional properties overseas — but a growing number of these clients also pursue a deliberate strategy of diversification, building a portfolio of properties spread across multiple countries as part of broader asset allocation. This global outlook echoes a pattern seen among wealthy families in the US and Europe, who have long treated a second or third home abroad as a standard part of a diversified portfolio; for Japan's ultra-high-net-worth households, it is a comparatively newer development.
These clients care about the quality of the entire process, not just the property itself. From the initial inquiry through contract and after-sales service, they consistently expect a high degree of privacy protection and meticulous attention. At the contract stage, coordination with a team of professionals — lawyers, tax accountants, and others — is essential, as is a solid grasp of matters like the differences between Tokyo's central six, three, five, and seven wards and how to choose an investment area accordingly, a level of granular local knowledge that has no easy equivalent in flatter, less administratively subdivided real estate markets abroad.
The distinguishing features of service for ultra-high-net-worth clients can be summarized as follows:
- A pursuit of scarcity and status: A preference for rare properties that rarely reach the open market, or properties carrying genuine historical value.
- A customized experience: Special staging at private viewings, concierge service, and a general treatment of a property purchase as a milestone event in life rather than a mere transaction.
- Rigorous attention to privacy: A desire to limit how widely property information circulates, and to keep the contracting process itself highly confidential.
- One-stop specialist support: Comprehensive expertise spanning legal and tax matters through to asset management, delivered through a single point of contact.
How does INA put ultra-high-net-worth service into practice?
In short, we deliver consistently high-quality service through private viewings, comprehensive support for overseas real estate investment, and dedicated property-management teams that continue working with clients after purchase.
For luxury condominiums in central Tokyo, INA shares property information with our trusted client network ahead of any public listing and holds private viewings before the property reaches the open market. We also draw on our connections within wealthy communities both in Japan and abroad to introduce opportunities for overseas real estate investment. Our support is comprehensive, ranging from arranging on-site visits to introducing professionals well versed in the relevant local laws and tax systems — an area where clients moving capital across borders often need more hand-holding than they would for a purely domestic purchase, given how much legal and tax treatment varies from one jurisdiction to the next.
After a purchase, a dedicated team continues to support the management and operation of the property, handling everything from tenant selection and contract management to arranging regular maintenance whenever the property is let out. Our stress-free rental management system reduces the burden on owners while working to maintain and increase the value of the property.
What is the outlook for the ultra-high-net-worth business going forward?
In short, the ultra-high-net-worth population is on an upward trend, and its needs are becoming more diverse and more sophisticated. This is an era in which value lies not just in the tangible asset of real estate itself, but increasingly in intangible qualities — service, experience, and trust.
We believe that people are the foundation of corporate value, and in the ultra-high-net-worth business in particular, success depends on having people who can build deep expertise and genuine trust with clients. INA will continue to stand alongside clients who value authenticity, and to keep delivering value that cannot be found anywhere else.
