How We Checked This Property
Because the road-access fields are blank, we located the property on the route price map from the listing's coordinates, and checked all eight listing photos, elevation data and other sites, separating what we could confirm from what remains unconfirmed.
What We Could Not Confirm
- The road access, private-road share, setback, terrain and remarks fields are all blank. The front road's classification, width and frontage length, and whether the house can be rebuilt, need to be confirmed with the agent.
- The only exterior photo shows the front door; the front road and boundaries are not shown. Any level difference to the road, whether it is a flag lot, retaining walls around the site and whether the house is terraced need to be confirmed on site or with the agent.
- The lot number is not disclosed, so the route price is a representative value of the local streets around the listing's coordinates. The value depends on the road the lot actually faces; across the local streets on this map sheet (69,000-83,000 yen/m²) the assessed ratio ranges from about 121% to 146%.
- The 3,900,000 yen price is below the route-price land value (about 5.48 million yen). The listing does not explain why, and this needs to be confirmed together with the road access and whether rebuilding is allowed.
- The house is a vacant 54-year-old wooden building built to the pre-1981 seismic code. Its condition, whether repair or demolition is needed and whether there is parking space are not stated in 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
⚠️ In this listing the fields for road access, private-road share, setback, terrain and remarks are all blank ("-"), so the classification and width of the front road and whether the house can be rebuilt have not been confirmed. The only exterior photo shows the front door and not the road, and we found no listing of the same property on other sites. We present it with road access unconfirmed; anyone considering it should first confirm with the agent the front road's classification, width and frontage length, and whether rebuilding is allowed.
A used detached house in Oaza Kita-Iriso, Sayama (lot number not disclosed), a 20-minute walk from Iriso Station on the Seibu Shinjuku Line. The two-storey wooden 3K house was built in October 1972 (54 years old), before the June 1981 seismic code revision. The freehold land is 68.51 m² (registered area) and the building 51.33 m², in an urbanisation-promotion area zoned Category 1 low-rise residential (50% building coverage, 80% floor area ratio), with public water, sewer and propane gas. It is vacant, handover is negotiable and no parking is mentioned. Measured in a straight line from the listing's map coordinates to OpenStreetMap locations, Welcia Sayama Kita-Iriso drugstore is about 480 m away, a Yaoko supermarket about 550 m and Lawson Sayama Kita-Iriso about 610 m; for dining, Teuchi Soba Jinsaku is about 530 m, Hidakaya Sayama Kita-Iriso about 590 m and Coco's Sayama about 700 m.
The fiscal 2026 inheritance-tax route price, taken as the representative value of the local streets around the property, is 80,000 yen/m², up 1.3% from 79,000 yen in 2024. The land is valued at about 5.48 million yen; the building is past its statutory useful life and counted at zero, giving an assessed ratio of about 140.5%. ⚠️ The 3,900,000 yen price is below the land value based on the area's route price (about 5.48 million yen). Possible reasons include the 54-year-old wooden building built to the pre-1981 seismic code and demolition costs, but the listing does not rule out that the road access makes rebuilding difficult.
What the photos show: the front door is at ground level with a stepping-stone path; the block wall on the right (about 0.8 m) is freestanding with the same ground on both sides, and the low concrete wall on the left is under 1 m. No retaining wall of 1 m or more, stairs or steps are visible. What they do not show: the front road and the rear and side boundaries are not in any photo, so the direction, width and level difference of the road access, whether the path to the door is a flag-lot strip, retaining walls around the site and whether the house is terraced could not be determined. No yield or expected rent is given.
