An Oceanfront Villa With Private Pool, Rooftop Terrace, And Sauna — Minamiboso

Property Highlights:

A private oceanfront villa on the southern Bōsō Peninsula, set apart from the city and built around a single view: open water from nearly every room. The living and dining room is conceived so that the sea remains present wherever one sits, and the bedroom looks directly onto it, so that the sound of the water carries into sleep. Large windows on the second-floor balcony open the interior to the horizon, in a monochrome palette softened by warm timber.

The outdoor spaces carry the house. A private pool faces the ocean, and a rooftop terrace is furnished with lounge seating and sun loungers for long afternoons and sunsets over the water. A private sauna offers a quiet counterpoint, and a built-in barbecue turns the terrace into a dining room at dusk. On clear nights, the lights of distant ships and the stars above the sea complete the view.

The villa is currently operated as a whole-house resort rental, so it comes with a working record as a hospitality asset. It can be kept as a private retreat, used as a business, or both.

The Neighbourhood:

Minamiboso sits at the southern tip of Chiba’s Bōsō Peninsula, where the climate is warm enough that spring arrives earlier than elsewhere in the Kantō region. Sea and mountains meet here, and the local table is built on fresh seafood and farm produce. The pace is unhurried, and the coast is far less crowded than Tokyo’s better-known resort shores.

Despite that distance, the peninsula is straightforward to reach from Tokyo. Guests arrive by car, train, express bus, or across Tokyo Bay by ferry, which makes the villa practical as a weekend house as well as a destination in its own right.
