How We Checked This Property

We checked two sheets of the FY2026 road price map, the on-site photos in the SUUMO listing of the same property, and GSI elevation data to verify how the road price was chosen, the level differences around the lot, and the listed restrictions.

Locating the road price

We counted each local road section in Kotoyahoncho 3-chome on the FY2026 road price maps (sheets 51011 and 51007) and used the most common value, 240,000 yen/m², as the representative price. Roads around the property are also in the 235,000–250,000 yen/m² range. The same road was 210,000 yen/m² in 2024 and 225,000 yen/m² in 2025.

On-site check from photos

The Kenbiya photos had no exterior shots, so we checked the on-site photos in the SUUMO listing of the same property (price, areas, completion date and building permit number all match). The private road and the parking area are at almost the same level, and the boundaries with both neighbours are one or two courses of block (about 0.2–0.4 m). The lot is a regular rectangle about 8.3 m wide and 13.9 m deep, not flag-shaped, and the house is not attached.

Rights and restrictions

The restrictions section states "Article 53 area under the City Planning Act". Because the listing does not give the affected area, no area was deducted and the full 115.07 m² was used. Land within the area of a planned city facility may be valued lower in the market because of building restrictions and the possibility of future expropriation.

Effective land area

The private-road burden is listed separately as a co-ownership share (1764/11303 of 113 m²), and the dimensions on the lot plan (8.26 m × about 13.9 m) match the 115.07 m² land area, so we concluded that the private road is not included in the land area. The road in front is 4.0 m wide and no setback is required.

Building valuation assumptions

The house is a new wooden building completed in September 2026, so the full 22-year statutory useful life is included in the building value.

What We Could Not Confirm

  • The listing does not give the name, width or approval status of the plan behind the Article 53 area, or how much of the lot it affects.
  • The listing does not state the type of the 4.0 m private road in front (for example, a designated road).
  • The southeast (rear) boundary is not shown in the photos; we only confirmed less than 0.4 m of relief on GSI elevation data.
  • The layout is described differently across listings, as 2LDK+S and as 4LDK+S.
  • The road price used is the block's most common value of 240,000 yen/m². At 220,000 yen/m² the ratio would be about 81.5%, and at the block's lowest band of 210,000 yen/m² about 79.5%.

※ Rather than reproducing the listing as-is, we verified the figures against public sources such as the official road price maps and the listing photos. This is not based on a site visit, so please confirm on site and with the seller before deciding.

About This Property

⚠️ The restrictions section of one agent's listing states that the property is in an "Article 53 area under the City Planning Act", meaning all or part of the lot may lie within the area of a planned city facility such as a city-planned road. The listing does not give the name of the plan, the area or proportion of the lot affected, or whether the project has been approved. Building within such an area requires permission and is in principle limited to structures of two storeys or fewer, with no basement, that can easily be moved or removed. If the project goes ahead, the affected part may be subject to expropriation (compulsory purchase). Please confirm the details of the plan with Adachi Ward's city planning office before considering a purchase.

This is a newly built detached house (a single-unit development) in Kotoyahoncho 3-chome, Adachi Ward, a 14-minute walk from Toneri Station on the Nippori-Toneri Liner. Completed in September 2026, it is a two-storey wooden house with 99.36 m² of floor area on a 115.07 m² freehold lot, in a Category 1 low-rise exclusive residential zone (50% building coverage, 150% floor area ratio). The ground floor has an LDK of about 16 tatami mats, and the second floor has three Western-style rooms and a walk-in closet. There is outdoor parking for two cars, and the house is currently vacant.

The asking price is 57.9 million yen, the same in both SUUMO listings. The FY2026 road price is 240,000 yen/m², the most common value among the local roads in the block, up about 14.3% from 210,000 yen/m² in 2024. The assessed land value is about 27.62 million yen and the new building is assessed at about 21.86 million yen, for a total of about 85.5% of the price. Because the building is new, its full value is included; it will fall by about 0.99 million yen for each year of age (about 83.7% a year from now at the same price).

The lot faces a 4.0 m private road on the northwest side and comes with a co-ownership share of that road. The listing does not state the road type, but the house was built with a building permit. In the photos, the level differences to the road and to both neighbours are small, and no retaining wall or stepped access is visible. The southeast (rear) boundary is not shown in the photos, but GSI elevation data shows less than 0.4 m of relief around the lot. The details of the city planning area should be confirmed before considering a purchase.

Estimated Financing

Assessed value ¥49,476,000 → estimated loan ¥49,470,000 (85% of the asking price)

※ Actual loan availability, amounts and terms are subject to each bank's screening.
