How We Checked This Property

Because neither on-site photos nor the street address are published, we estimated the location from the listed distances to nearby facilities and checked it against the 2026 road price maps, Tokorozawa's assessment multiplier table and other sites listing the same property.

Locating the road price

Oaza Yamaguchi is a district where road-price areas and multiplier areas are mixed. We confirmed in Tokorozawa's 2026 assessment multiplier table that the urbanization promotion area of Yamaguchi uses road prices while the urbanization control area uses multipliers, and valued this property, which lies in the urbanization promotion area, by road price. As the district is large and has no chome subdivisions, we counted the local streets in the southern half of road price map sheet 34084, which corresponds to an 8-minute walk from Nishi-Tokorozawa Station, and used the most common value, 130,000 yen/㎡ (about 13 sections, leasehold ratio D). The next most common is 140,000 yen/㎡ (about 7 sections); we did not use the 145,000 and 150,000 yen/㎡ values along the Tokorozawa-Ome prefectural main road, which are of a different character. For the three-year trend we followed the same street near the property: 125,000 yen/㎡ in 2024, 125,000 yen/㎡ in 2025 and 130,000 yen/㎡ in 2026.

Effective land area

The listing shows no private road burden and a 7.6m-wide public road to the north. There is no mention of setback, sloped portions or a flag-shaped access strip, so we used the land area of 107.49㎡ as is. However, the only drawing in the listing is the floor plan of the building, with no site plan, so we could not confirm whether the lot is flag-shaped.

Listing check

The address is published only down to the district, and the map pin in the listing appears to be a representative point for the district (from there to Yamaguchi Nursery School is about 130m, which does not match the listed 850m). The only area that satisfies all the listed facility distances (7-Eleven Nishi-Tokorozawa Yamaguchi 160m, Izumi Elementary School 670m, Yamaguchi Nursery School 850m, Seiyu Nishi-Tokorozawa 860m, Yamaguchi Junior High School 1,540m, Nishi-Tokorozawa Station 8 minutes on foot) is within about 160m of 7-Eleven Nishi-Tokorozawa Yamaguchi. Road prices in that area range from 98,000 to 140,000 yen/㎡; even the lowest, 98,000 yen/㎡, gives an assessed ratio of about 82.1%, and 125,000 yen/㎡ gives about 92.3%.

On-site check from photos

The 10 listing images on SUUMO are one floor plan and nearby facilities only, and the 11 images on LIFULL HOME'S, which lists the same property, are likewise one floor plan and 10 nearby facilities. We could not find this property in the Tokorozawa pre-owned house listings on Yahoo! Real Estate or at home either. Retaining walls, height difference from the front road, step-only access, whether the lot is flag-shaped, whether the house is attached, and the exterior could not be judged from photos. The floor plan shows windows on the west side of the ground-floor LDK and the east side of an upstairs Western-style room, so the house has openings on both side walls and is probably not attached, but this has not been confirmed by photos. The entrance faces the road to the north. Because the street address is unknown and elevation data for the estimated location could not be obtained, we could not gauge height differences from the terrain either.

What We Could Not Confirm

  • With no on-site photos, we have not been able to confirm whether there is a retaining wall or a height difference from the front road (including whether the lot can only be reached by steps). This needs an on-site check or an inquiry to the agent.
  • No site plan is published, so it is unknown whether the lot is flag-shaped (reaching the road through a narrow strip), or what its frontage and shape are. It has also not been confirmed by photos that the house is not attached to a neighbouring building.
  • The condition of the exterior of the 2018 building (walls, roof, foundation, etc.) has not been confirmed because there are no photos.
  • The address is published only down to Oaza Yamaguchi, and the road price was taken at a location estimated from the listed distances to nearby facilities. The precision is therefore rough; applying the lowest value in the estimated area, 98,000 yen/㎡, gives an assessed ratio of about 82.1%.

※ 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

⚠️ None of the listings for this property include a single on-site photo (the listing images are only a floor plan and nearby facilities), so we have not been able to check for retaining walls, a height difference from the front road, whether the lot can only be reached by steps, whether the house is attached to a neighbouring building, or the condition of the exterior. The thumbnail is an illustration made by this site. This is a pre-owned detached house in Oaza Yamaguchi, Tokorozawa, listed as an 8-minute walk from Nishi-Tokorozawa Station on the Seibu Ikebukuro and Sayama Lines and a 19-minute walk from Shimo-Yamaguchi Station on the Seibu Sayama Line. The address is disclosed only down to the district (oaza), and the map pin in the listing appears to be a representative point for the district, so we estimated the location from the listed distances to nearby facilities as within about 160m of 7-Eleven Nishi-Tokorozawa Yamaguchi.

The house is a two-storey wooden building completed in November 2018 (7 years old) with 86.94㎡ of floor area and a 4LDK layout (16-tatami LDK, a 4.5-tatami Japanese-style room and Western-style rooms of 6.2, 5 and 5 tatami). All rooms face south and have storage, and there is parking for one car. The land is 107.49㎡, freehold and registered as residential land, with no private road burden, and it faces a 7.6m-wide public road to the north. The zoning is Category 1 Residential (building coverage 60%, floor area ratio 200%) within the urbanization promotion area, with public water, public sewer and individual LPG. Listed restrictions are the Civil Aeronautics Act, the landscape ordinance, Tokorozawa's location optimization plan (inside the residential inducement area) and the ordinary zone of Sayama Prefectural Natural Park. The price is 28.7 million yen; the seller currently lives in the house and the handover date is negotiable. The listing is aimed at owner-occupiers and shows no yield.

Oaza Yamaguchi is a district where road-price areas and multiplier areas are mixed, but Tokorozawa's assessment multiplier table treats the urbanization promotion area of Yamaguchi as a road-price area, and this property lies within that area. For the road price we used 130,000 yen/㎡ (leasehold ratio D), the most common value among local streets within an 8-minute walk of Nishi-Tokorozawa Station; it has risen about 4.0% over two years from 125,000 yen/㎡ in 2024. The building is still young enough to carry value, and the assessed ratio of land plus building is 94.1%. Streets around the estimated location range from 98,000 to 140,000 yen/㎡; applying the lowest, 98,000 yen/㎡, gives about 82.1%.

This is a fairly new wooden house 8 minutes on foot from the station, with a land-plus-building assessment close to the asking price. However, since nothing could be confirmed from photos, retaining walls, height differences, the shape of the lot and the exterior condition need to be checked at a viewing or with the agent. Among the nearby places, the three shops use the distances in the listing's surroundings section, and the three restaurants use straight-line distances from 7-Eleven Nishi-Tokorozawa Yamaguchi (the reference point of the estimated location) to their OpenStreetMap positions; we confirmed that all of them are in Tokorozawa.

Estimated Financing

Assessed value ¥27,014,700 → estimated loan ¥27,010,000 (94% of the asking price)
