How We Checked This Property
Rather than reprinting the listing, we checked the figures against the 2026 road-price map, four listing photographs and national elevation data.
What We Could Not Confirm
- For the 3.8 m private road on the north, the listing does not state whether a share in the road or written consent to pass and excavate is included. This needs confirming with the seller.
- The site fronts a private road under 4 m wide, yet the setback field is blank. Whether a setback will be required on rebuilding needs confirming with the local authority.
- The building assessment uses the listed 114.85 sqm including the 15.10 sqm garage. Excluding the garage gives 78.7 percent, so the treatment of the garage moves the property across the 80 percent line.
- The remarks note that part of the adjoining land to the east has the form of a road but is private property and cannot be entered. The actual route of access should be checked on site.
- Construction is still under way, so external works and the finished state of the front road may differ from the photographs.
※ 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 newly built detached house in Minami-Hatogaya 8-chome, Kawaguchi, Saitama, a 10-minute walk from Minami-Hatogaya Station on the Saitama Railway Line. Hatogaya Station on the same line is 21 minutes on foot. The line runs through to the Tokyo Metro Namboku Line at Akabane-Iwabuchi, giving a direct ride towards Oji, Iidabashi and Meguro.
Two points deserve attention up front. The first is the front road: the site faces a 3.8 m private road on the north. Although this is under 4 m wide, the listing leaves both the setback and private-road-burden fields blank, and says nothing about whether a share in the private road or consent to excavate and pass is included. Building confirmation has been issued (No. KSI26-312051039) and construction is under way, so buildability itself is evidenced, but as this affects future rebuilding and utility work, please confirm the share and the consent documents with the seller.
The second is the floor area. The 114.85 sqm floor area includes a built-in garage of 15.10 sqm, or 13 percent of the total. This site uses the listed floor area as published for the building assessment, so the garage is valued at the same unit rate as living space. Calculated on 99.75 sqm excluding the garage, the building value would be 21,945,000 yen and the assessed ratio would fall to 78.7 percent. This property sits across the 80 percent line depending on how the garage is treated.
The house is a three-storey wooden 4LDK built in September 2026, on 64.30 sqm of land (surveyed). The land is freehold, the category is residential land, and the zoning is Category 1 mid-to-high-rise exclusive residential (60 percent building coverage, 200 percent floor-area ratio). The 2026 road price is 185,000 yen per sqm, giving a land value of 11,895,500 yen. As the building is brand new, its full assessed value of 25,267,000 yen remains, so against the asking price of 42.99 million yen the assessed ratio is 86.4 percent. The road price rose 15.6 percent over three years, from 160,000 yen in 2024 to 185,000 yen in 2026.
Four listing photographs show the site level with the private road, with one or two steps (20 to 30 cm) up to the entrance. Boundary walls on the east and west are all under 0.5 m of retained height with essentially equal ground levels on both sides. Elevation data sampled at 49 points across 60 m shows relief within 0.3 m, and the site plan confirms a regular plot fronting the north road rather than a flagpole lot.
