326 Sqm Single Floor Residence In Hiroo, Tokyo — Only 4 Homes In Building

① Property Highlights
In Tokyo, space is the ultimate currency. Privacy is its highest denomination. Most developments in this city chase vertical height. This residence defines itself by something rarer: horizontal scale — 326.29 sqm across a single floor, on the top floor of the building. In central Tokyo, at this address, that number is not a specification. It is an anomaly.

Within this address, just four residences. Not four per floor. Four in the entire building — joined by two private lounges, across four floors of reinforced concrete, constructed by Shimizu Corporation and completed June 1982. The scale renders the concept of neighbors almost theoretical — the discretion of a private mansion, held within the structure of a managed estate.

The interior was reimagined by OEO Studio, Copenhagen — their philosophy of Compelling Minimalism, a precise fusion of Scandinavian restraint and Asian aesthetics. Four balconies. Living, dining, the master suite and the secondary bedrooms each open to their own outdoor space, dissolving the boundary between interior and the greenery of one of Tokyo’s quietest residential streets. A master suite arranged with the logic of a boutique hotel, its own walk-in closet and en-suite bathroom, joined by two further bedrooms. A kitchen island designed for those who cook with intention and entertain without effort.

326.29 sqm (98.70 tsubo). 4LDK. Top floor. 4 residences in the building. Freehold. Hiroo, Shibuya-ku.

② The Neighbourhood
Hiroo’s diplomatic enclave is home to more than 50 embassies. Arisugawa-no-miya Park — 63,000 sqm of mature woodland — borders the neighborhood to the east. National Azabu, Tokyo’s most internationally stocked market, is within walking distance. The register here is immediate and instinctive to anyone who has lived in South Kensington, the 7th arrondissement, or Orchard Road. It does not need to be explained. It simply is.

Hiroo Station, on the Tokyo Metro Hibiya Line, is nine minutes on foot. Roppongi, Shibuya, Daikanyama, and Tokyo Tower are all within the immediate surrounding radius — Ginza and the Imperial Palace a short drive beyond.

Embassies do not relocate. International schools do not move. The community built around them is permanent — and so is the value it sustains.
