Ark Hills Sengokuyama: The 20 Minute Radius A Legacy Of Security, Positioned Above The Ordinary.

Sengokuyama sits on a historic ridge that once formed part of Tokyo’s imperial and aristocratic estates — a zone of elevated ground that the city’s ruling class understood, long before the concept of real estate existed, as the correct place to be. That understanding has not changed. Today, the same ridge maintains a 30% greenery ratio in the heart of the urban core, constant diplomatic security patrols, and a residential character defined by precisely the kind of people who do not need to announce where they live.
The residence itself is engineered for performance, not display. 130.60 sqm across two bedrooms, walk-through closet, and living and dining — positioned on the third floor of a 47-storey tower designed by Cesar Pelli, with intentional street-level access that eliminates elevator wait times and maximizes daily mobility. A 30.81 sqm balcony. Fully renovated January 2026 with premium materials throughout.
Haneda International Airport is 20 minutes away — direct, without friction, from private jet to residence. Ginza and Roppongi are five minutes by car. Azabudai Hills, the most significant new mixed-use development in Tokyo’s recent history, is within immediate reach. Three stations and three major subway lines are within walking distance.
The building carries the structural and architectural pedigree of Cesar Pelli. Private backup power systems and solar generation ensure continuity in any scenario. Sky Lounge, View Lounge, Rooftop Garden Corridor, 24-hour concierge, guest rooms, trunk rooms, and secured underground parking complete an amenity profile that functions with the efficiency of a world-class managed property.
