World City Towers is a group of towers at 4-6-2 Konan in Minato Ward, completed in October 2005; Aqua Tower rises forty-two storeys above ground and two below. This thirtieth-floor residence is a 2LDK of 94.02 sq m, south-east facing and dual-aspect, with a balcony of 5.90 sq m.
The 94.02 sq m is recorded on the internal measurement — the area inside the walls. Japanese listings quote floor area on one of two conventions, the internal measurement or the larger wall-centre measurement taken to the centre line of the walls, and a residence quoted on the internal basis is therefore larger than the same number quoted on the wall-centre basis elsewhere. The distinction matters when comparing this residence with others on this site.
The building is managed under a fully outsourced contract by Sumitomo Real Estate Building Services with a resident caretaker and a management association in place. Shared facilities recorded in the listing material include a front service, a children's room and a rooftop garden, with security cameras and 24-hour security, and the grounds are landscaped between the towers. The residence is occupied by its owner and handover is by consultation.

Floor area is the internal measurement from the listing material and remains subject to verification against the register; it is not directly comparable with a wall-centre figure. The source records do not state the total number of residences in the building.
Monthly charges are the management fee of JPY 23,178 and the repair reserve contribution of JPY 48,660 as stated in the listing material. Parking, if taken, is a further JPY 48,000 a month.
The repair reserve is the larger of the two charges, which is normal in a building of this age and scale and indicates that contributions have already been stepped up on the long-term repair plan.
Floor area is quoted on the internal measurement. See the note in the details table.
The towers stand at 4-6-2 Konan in Minato Ward, on the bay side of Shinagawa between the station and the Tennozu canal. The listing material records Shinagawa Station on the JR Yamanote Line at approximately fifteen minutes on foot, Tennozu Isle on the Tokyo Monorail Haneda Line at five and Tennozu Isle on the Rinkai Line at eight.
Shinagawa is one of Tokyo's principal interchanges, with the Tokaido Shinkansen, the Yamanote and Keihin-Tohoku lines and the Keikyu line to Haneda Airport; the monorail from Tennozu Isle reaches Haneda directly. Journey times vary with the service and any changes, so none are stated here.
Konan is a waterfront district of towers, offices and canals, with the shops and restaurants of the Shinagawa station complex, the Tennozu Isle waterfront and Shinagawa Central Garden close by.

In the At Home – Sumitomo Mitsui Trust Research Institute Mansion Rent Index for Q1 2026, the family-type index for Tokyo’s 23 wards — units of 60 to under 100 sq m, the band this 94.02 sq m residence falls into — rose approximately 12.3% year on year.
In the Reiwa 8 (2026) Official Land Price Survey, residential land in Minato Ward rose 16.6% on the previous year, and the all-use average for the ward rose 15.0%. The Ministry of Land, Infrastructure, Transport and Tourism’s Real Estate Price Index puts condominium prices in Tokyo at 234.8 for December 2025 against a 2010 average of 100 — a rise of approximately 9.6% on the same month a year earlier.
These figures describe Tokyo’s 23 wards, Minato Ward and Tokyo as a whole, not this individual property. The rent index covers quality-adjusted contracted rents for condominium-type buildings, not this address; the land figure is an average across all official reference points and is not an appraisal of this address; the price index is a nationwide statistical series for Tokyo. None of them guarantees future rent, value or performance.

Ninety-four square metres in Minato Ward is a proper family home rather than a compact city flat, and the figure here is measured the conservative way. Japanese listings quote floor area either internally or to the centre of the walls, and this one is quoted internally — so against a residence advertised at the same number on the wall-centre basis, this one is the larger home. It is the single most useful thing to understand about this listing.
The thirtieth floor of forty-two, south-east facing and dual-aspect, over the water toward Shinagawa. The building dates from 2005, has a resident caretaker rather than a daytime one, and carries a repair reserve of JPY 48,660 a month — more than twice the management fee. That ratio is what a well-run twenty-year-old tower looks like: the money for the next major repair cycle is already being collected rather than deferred to a future lump-sum levy.
The fifteen-minute walk to Shinagawa is the honest figure and the reason this is priced where it is; the monorail at Tennozu Isle is five minutes away and reaches Haneda directly, which for an owner who travels is worth more than the Yamanote line. Minato Ward recorded a 16.6% rise in residential land prices this year, the highest of the five central wards. The long-term repair plan and the management rules can be confirmed on enquiry.
This property is introduced through a Japanese real estate partner. Availability, price and property details remain subject to confirmation at the time of enquiry.
