The Aristocratic Heights Of Mita: A Master Planned Urban Estate With Imperial Hotel Service.

① Property Highlights
In central Tokyo, the rarest form of luxury is not height. It is not visibility. It is land — and what land, at this scale, in this ward, now means.

Mita Garden Hills rises upon one of the largest residential landholdings in Minato-ku — a site of over 25,000 sqm, set approximately 20 metres above sea level on elevated ground that has, across every global city from London’s Hampstead to Hong Kong’s Peak, historically defined where enduring residential value is held. The elevation is not incidental. It is structural — reducing flood exposure, improving seismic resilience, and creating a natural separation from surrounding urban density that no planning regulation can replicate once it is gone.

At the entrance to the estate stands the preserved 1929 façade of the former Postal Insurance Bureau. Residents pass through a century of history before entering contemporary life. That transition is not symbolic. It is experiential — and it happens every time you come home.

Within a master-planned estate of over 1,000 residences, the Park Mansion collection occupies a far more limited allocation — a quieter layer within a larger vision, developed by Mitsui Fudosan Residential, Japan’s most established residential developer, constructed by Taisei Corporation, and completed March 2025. The concierge service operates in partnership with the Imperial Hotel Tokyo. Valet parking. Fitness, spa, lounges, dining facilities, and guest suites on-site. This is not a building with amenities. It is a residence supported by hospitality — every element designed to make ownership feel effortless.

The residence spans 128.43 sqm (1,383 sq ft) across three bedrooms with walk-in closet and shoe closet, positioned on the third floor of a 14-storey building.

Land of this scale in Minato-ku is not replicable. It was assembled once. It will not be assembled again.

128.43 sqm. Park Mansion. Mita Garden Hills. Freehold. Minato-ku.

To own here is not simply to reside in Tokyo. It is to hold a position within it — quietly, permanently, and with certainty.

② The Neighbourhood
Azabu-Juban Station — Tokyo Metro Namboku Line and Toei Oedo Line — is a five- to seven-minute walk. From there, the city opens in every direction: Roppongi in two minutes, Otemachi in seven, Shinjuku in twelve, Shinagawa in twenty. Mita Station, on the Toei Mita and Asakusa lines, is a further option, minutes from the estate.

The neighbourhood itself has held its character for generations. The Italian and Australian embassies stand nearby. Tsunamachi Mitsui Club, one of Tokyo’s most storied private clubhouses, sits within the same quiet blocks. Keio University’s main campus is a short walk away. Azabu-Juban’s shopping street, with its long-established restaurants and boutiques, is approximately 900 metres from the estate. Shiba Park — one of Tokyo’s oldest public parks, laid out in the shadow of Tokyo Tower — and Arisugawa-no-miya Memorial Park are both within 1.3 kilometres. Azabudai Hills, the city’s newest landmark district, is 1.8 kilometres away.

This is Minato-ku at its most established — embassies rather than office towers, private clubs rather than public spectacle, a residential fabric that has changed remarkably little while the rest of Tokyo transformed around it.
