How We Checked This Property

We checked the 2026 road price map against the Kenbiya, SUUMO and HOME'S listings, the lot plan and exterior photos to resolve the differing floor areas and how to treat the private road share.

Locating the road price

We traced the block roads of Hanazono 1-chome on the 2026 road price map (sheet 34011). Three roads are ¥130,000/m² and two (dead ends) are ¥125,000/m², so we used the most common value, ¥130,000/m², both for the northern area where the house is and for the whole district. The ¥145,000–150,000/m² roads in the southern part are away from the house and were not used.

Effective land area

HOME'S and SUUMO list a private road share of 19.88 m², but Kenbiya does not. The lot plan's 9.77 m × about 11.45 m matches the 112.04 m² of land, and if the share were included the floor area ratio would exceed the designated 80%, so we treated it as a separate parcel and did not deduct it (assessed ratio about 90.0%). If deducted, the effective site area would be 92.16 m² and the ratio about 83.2%.

Building valuation assumptions

The floor area is 90.46 m² on Kenbiya and HOME'S but 89.23 m² on SUUMO (with a 1.23 m² storage room listed separately), so we used the smaller 89.23 m². Using 90.46 m² would give an assessed ratio of about 90.7%. There is no built-in garage; parking is for two cars side by side on the lot.

On-site check from photos

We checked the listing photos and the lot plan. From the northern road, the front is a concrete apron level with the road and the entrance has two steps (about 0.3 m). There is no retaining wall, no drop of 1 m or more and no stepped access, and the neighbours to the east and west are at the same level. The lot is a regular rectangle, not a flag lot, and the house is detached.

What We Could Not Confirm

  • The listings do not establish whether the 19.88 m² private road share is included in the 112.04 m² of land or is a separate parcel. If included, the effective site area would be 92.16 m² and the assessed ratio would fall to about 83.2%, so this needs to be checked against the registry and cadastral map.
  • The front road (north side, 4 m wide) is described as public, but because a private road share is also listed, part of the road may be a private share; the road classification needs to be confirmed.
  • There are no photos of the southern (rear) boundary, so its condition and any level difference could not be confirmed.
  • The yield is listed as not yet set, and the rental income cannot be determined from the listing.

※ 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

This is a newly built detached house in Hanazono 1-chome, Tokorozawa, Saitama. It is an 18-minute walk to Shin-Tokorozawa Station on the Seibu Shinjuku Line and a 36-minute walk to Kotesashi Station on the Seibu Ikebukuro Line. The area is a Category 1 low-rise exclusive residential zone. Measured in a straight line from the map coordinates in the listing to each store, nearby are York Foods Tokorozawa Hanazono (about 650 m), Co-op Shin-Tokorozawa (about 630 m), Yamada Udon (about 630 m), Tokusei Ramen Hasegawa (about 640 m) and Ootoya (about 720 m). These are straight-line distances, not walking routes.

Completed in March 2026, this is Building No. 1 of the development: a two-storey wooden (post-and-beam) 3LDK house with an LDK of about 19.7 tatami mats, built to ZEH standards. The land is 112.04 m² (registry), held freehold, with a 50% building coverage ratio and an 80% floor area ratio. It faces a 4 m-wide public road to the north with about 9.7 m of frontage and no setback. The floor area is listed as 90.46 m² on Kenbiya and HOME'S but 89.23 m² on SUUMO (with a 1.23 m² storage room listed separately), so the assessment uses the smaller 89.23 m². There is no built-in garage; the lot has parking for two cars side by side. The house is vacant and available immediately, and the yield has not been set.

⚠️ HOME'S and SUUMO list a private road share of 19.88 m² (Kenbiya does not), and the listings do not make clear whether it is included in the 112.04 m² of land or is a separate parcel. Because the side lengths on the lot plan (9.77 m × about 11.45 m) match the listed land area, and because treating it as included would push the floor area ratio to about 96.8%, above the designated 80%, we judged it to be a separate parcel and did not deduct it. On that basis the assessed ratio is about 90.0%. If it were deducted from the land, the effective site area would be 92.16 m² and the assessed ratio about 83.2%.

Because the house is new, the building is valued close to its full replacement cost. The road price is ¥130,000/m² (2026), up about 4.0% from ¥125,000 in 2024. Whether the private road share is included in the land, whether part of the front road is a private share, and the condition of the southern boundary could not be confirmed from the listings or photos, so they should be checked against the registry and cadastral map and with the agent.
