The Villa That Faces Mount Fuji — Beachfront On The Bōsō Coast

Property Highlights:

Built by Mitsui Home on a low bluff above the Uchibō shoreline, two white volumes step down the slope to a terrace, a lawn, and a floodlit basketball court. The sea sits directly in front, a wooded ridge behind, and on clear evenings Mount Fuji stands across Tokyo Bay — all of it little more than an hour from central Tokyo by car via the Tokyo Bay Aqua-Line.

The residence spans 295.47 sqm across three storeys of certified long-life quality timber-frame construction (2×6), completed circa 2020 — 169.61 sqm on the ground floor, 99.94 sqm on the second, 25.92 sqm on the third, set on a footprint of 200.03 sqm. Five bedroom-capable rooms, two bathing suites, and three WCs are arranged as configured for short-stay operation, with a living and dining volume of 63.76 sqm beneath a 3.0-metre ceiling. The grounds carry a private basketball court, an outdoor kitchen, a fire pit, lawn, palms, and a stone motor court.

Original construction cost was approximately ¥500 million; Japanese construction costs have risen steeply enough since completion that rebuilding today would exceed ¥1 billion. The property runs today as a licensed short-stay villa, with booking and revenue records available under NDA — so it comes to market with an operating history rather than a theory of one. It answers a brief most Japanese inventory at this level cannot: a large-format, resort-grade house barely an hour from Tokyo and warm enough to use year-round, where comparable properties at Karuizawa, Hakone, or Niseko sit inland, cold, and three hours away.

Freehold, foreign ownership permitted. 295.47 sqm. ￥900,000,000.

The Neighbourhood:

The property sits on Ryū Shima, in Kyonan-machi, on Chiba’s Uchibō coast along the Bōsō Peninsula — a stretch of coastline defined by sea frontage across the local coast road and a wooded ridge behind, with Ryū Shima Beach a few minutes on foot. From Tokyo, the drive runs just over an hour via the Tokyo Bay Aqua-Line and the Tateyama Expressway; from Haneda Airport, approximately 45 minutes.

Because the property is not publicly marketed, access follows a private sequence: an expression of interest, a signed non-disclosure agreement, then release of the full memorandum — address, title, survey, complete drawing set, operating accounts, and guide price. Private inspections are arranged around the operating calendar, typically with a few days’ notice, with viewing days hosted from Tokyo, road transfer included.
