How We Checked This Property

Rather than reproducing the listing as-is, we enlarged the FY2026 road price map PDF to pick a representative point, then checked whether the spread of nearby values would change the conclusion.

Locating the road price

On the FY2026 road price map for Kawagoe (sheet 26144), we took ¥77,000/m² from the block street bordering Nakadai-Minami 1-chome, west of Nakadai-dori. The district runs ¥75,000–79,000/m²; at either end of that band the assessed ratio still lands between 105% and 110%.

Effective land area

The listing marks the private-road burden as "none" and notes no setback or flagpole extension, so the full registered area of 125.1 m² is used for the land valuation.

Building valuation assumptions

Against the 22-year statutory life for wood-frame construction, the building dates from September 2017 — 8 years old with 14 years remaining. Its assessed value exceeds the land, making up more than half of the 107.9% ratio.

Rights and restrictions

The only restriction noted is landscape-act regulation; there is no mention of a cliff ordinance, retaining wall, level difference, slope, land development control zone, restriction on rebuilding or leasehold. The land is held in freehold.

What We Could Not Confirm

  • The listing gives no direction, width or contact length for the frontage road, so we recommend confirming the road situation from documents and on site.
  • The southeast part of Nakadai-Minami 1-chome falls in a multiplier zone with no road price. Once the street number is known, the frontage road price is worth re-checking.

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

A pre-owned detached house in Nakadai-minami 1-chome, Kawagoe City, Saitama, an 18-minute walk from Minami-Otsuka Station on the Seibu Shinjuku Line. In front of the station are the Marunaka Minami-Otsuka and Inageya Kawagoe Minami-Otsuka Ekimae supermarkets, plus the Chinese restaurant Ajisai just outside the north exit, covering everyday shopping and eating out. Buses also run to Hon-Kawagoe Station, giving access to central Kawagoe.

The property is a 4LDK on 125.1 sqm of land (registry) with a 92.32 sqm building (registry), wooden and two storeys, built in September 2017. There is no private-road burden and the land is held in freehold. Zoning is Category I Low-Rise Exclusive Residential with a 50% building coverage ratio and an 80% floor area ratio; the only other restriction noted is landscape-act regulation. Specifications include parking for two cars, an LDK of 15 tatami or more, a face-to-face kitchen, two toilets and double-glazed windows.

On the assessment side, against the 2026 inheritance-tax roadside land value of 77,000 yen/sqm the land assesses at roughly 9.63 million yen. At eight years old the building still has 14 of the 22-year statutory useful life for wooden construction remaining, adding roughly 12.92 million yen. The total assessed value comes to about 22.56 million yen, or roughly 107.9% of the 20.90 million yen asking price. In this price band, the thick remaining building value of a relatively new house is what makes the difference.

That roadside value has risen only 1.3% in three years from 76,000 yen in 2024, but because the price is restrained the assessed value still exceeds it. The station is a fair 18 minutes away, but two parking spaces are secured.

Estimated Financing

Assessed value ¥22,557,500 → estimated loan ¥20,900,000 (100% of the asking price)
