① Property Highlights The estate was completed in 2019 across 801.59 sqm (8,628 sq ft) of freehold coastal land. Reinforced concrete, two floors and basement, cedar and glass softening the structure’s presence. Elevator across all levels. Full air-conditioning and underfloor heating throughout. A garden-level spa opens toward camellia gardens and greenery. Upper levels frame shifting light — morning over the ocean, evening over Fuji.
The configuration — a three-bedroom wing alongside a fully self-contained two-bedroom suite — offers operational flexibility that few estates of this nature provide: primary residence with independent guest accommodation, multi-generational family living, or private staff quarters, without compromise in any direction.
The horizon from the rooftop terrace — Sagami Bay to the south, Enoshima at the edge of the water, Mount Fuji rising with quiet clarity to the northwest — is not a view that today happens to exist. It is a view the law has guaranteed will not be taken.
Coastal freehold land of this scale, within a protected low-rise zone, no longer comes to market in this part of Japan. That sentence will only become more true with time.
To own this estate is not to acquire a residence. It is to secure a legacy — measured not in years, but in generations.
② The Neighbourhood There are coastlines that are beautiful. And there are coastlines that are protected — legally, permanently, and in a way that means what you see today is precisely what will remain. The Shōnan coast is Japan’s most celebrated coastal lifestyle destination — the stretch of Pacific shoreline southwest of Tokyo that has long drawn those seeking space, nature, and a quieter cadence of living. It is to Tokyo what the Hamptons are to New York, or the Côte d’Azur to Paris.
And within it, Kugenuma Matsugaoka sits in a first-class low-rise residential and scenic preservation district where vertical development and subdivision are legally prohibited.
Kugenuma Station is a three-minute walk. Central Tokyo is approximately 60 minutes by direct rail. Kamakura’s historic streets and temples are minutes away. Enoshima’s waterfront is within immediate reach.
③ Why TonTon This is the kind of asset that does not reach the open market through conventional channels. As the exclusive Japan licensee of Forbes Global Properties, TonTon operates at the precise intersection of deep local knowledge and a truly global network — giving our clients access not only to properties of this nature, but to the discretion, due diligence, and cross-border expertise that a transaction of this significance demands.

From corporate structure establishment and tax advisory coordination to post-acquisition asset management, we provide end-to-end support across the full acquisition journey.
For clients whose ambitions extend beyond the visible, our private portfolio awaits.
Japan holds something rare in the world of luxury real estate: properties that do not announce themselves, estates
Japan holds something rare in the world of luxury real estate: properties that do not announce themselves, estates shaped by centuries of cultural intention, and land whose value is understood only by those who seek it with patience.
TonTon Forbes Global Properties was founded to serve that pursuit. As Japan’s exclusive partner of Forbes Global Properties, we operate at the intersection of deep local knowledge and a truly global network — giving our clients access not only to the finest listed properties, but to the opportunities that never reach the open market.
We work with a deliberately small number of clients at any one time. This is a choice, not a limitation. It allows us to provide the level of attention — to due diligence, to cultural nuance, to long-term advisory — that exceptional real estate demands.
Our team is fluent in the language of international acquisition: the questions that matter, the timelines that must be respected, and the sensitivities that distinguish a transaction from a legacy.
For clients whose ambitions extend beyond the visible, we are ready to begin.
Our advisory team brings together backgrounds in international finance, Japanese property law, and cross-border transaction management. All client engagements are led by a named advisor — ensuring continuity, accountability, and the depth of relationship that exceptional decisions require.
