How We Checked This Property

We checked two FY2026 route price maps, the athome exterior and parking photos and floor plan, and the other agents' listings for the same house to examine the flag-shaped lot and the private road burden.

Locating the road price

On the FY2026 route price maps (sheet 40307; the northern part of 4-chome is on 40303), the local streets of Owada 4-chome are ¥150,000/㎡ on about nine sections and ¥145,000/㎡ and ¥155,000/㎡ on one section each, so we adopted the most common value, ¥150,000/㎡. The 6m private road in front has no route price, and the ¥175,000–185,000/㎡ values on arterial roads such as the Kawagoe–Niiza prefectural road were excluded. Using ¥145,000/㎡ would give an assessed ratio of 78.8%. The map position differed between listings, but the local streets around both positions are ¥150,000/㎡. The same street was ¥145,000/㎡ in 2024 and ¥150,000/㎡ in 2025 and 2026.

Effective land area

Treating the lot as flag-shaped with a 2.5m frontage, we deducted the access strip as 2.5m × 5.0m = 12.5㎡ (a minimum estimate based on one parking space), giving an effective area of 104.04㎡. Taking the strip as about 6m deep (15㎡) from the fence in the photos gives 79.3%; without the deduction it is 86.8%. The private road burden differs: 27.32㎡ in three SUUMO listings, 'none, surveyed 116.54㎡' at Tokyu Livable, and blank on athome. We did not deduct it, treating it as a separate parcel, because including 27.32㎡ in the lot would put the building coverage at about 63% based on the ground-floor area measured from the floor plan (approx. 56.5㎡), above the designated 60%, and because Tokyu Livable says 'none'. Deducting it as part of the lot gives 73.1% (66.8% with the strip also deducted).

On-site check from photos

We checked three exterior photos, a parking photo and the floor plan on athome. The private road and the parking space are at the same level, and the entrance porch has two or three steps. The land sits above a narrow channel-like passage outside the southwest boundary; the step reads as about 0.3–0.5m at the road end and up to about 0.85m at the far end, judged against the fence height. No step of 1m or more, retaining wall or stairway access was seen. The left side of the building front is hidden behind the neighboring house and the lot connects to the road only through the parking space, which is why we treat it as flag-shaped.

What We Could Not Confirm

  • No lot plan is available, so whether the 27.32㎡ private road burden is a separate parcel or part of the lot has not been confirmed. The listings also do not show the share of the private road or whether consent for passage and excavation exists.
  • The flag shape is inferred from the 2.5m frontage and the exterior photos (the left side of the building front is hidden behind the neighboring house), and the area of the access strip (12.5–15㎡) is also estimated from the photos. The actual dimensions need to be confirmed on a survey plan.
  • The step to the southwest passage (up to about 0.85m) is read from the photos, not measured. The rear (southeast) boundary does not appear in the photos.
  • The lot number is not disclosed, and the map position differs between listings. The route price of the nearby local streets is ¥150,000/㎡ at either position.

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 pre-owned detached house in Owada 4-chome, Niiza, Saitama. It is a 15-minute walk from Niiza Station on the JR Musashino Line; the listing also gives a bus route from Shiki Station on the Tobu Tojo Line with a 3-minute walk from the stop. The land is in a quasi-residential zone (building coverage 60%, floor area ratio 200%) within the urbanization promotion area, and is also covered by a landscape plan area and a height control district. It fronts a 6.0m-wide private road on the northwest side. Nearby are Sukiya (approx. 190m), 7-Eleven (approx. 240m), Kohikan (approx. 270m), Kentucky Fried Chicken (approx. 400m) and LOPIA (approx. 480m). These are straight-line distances from the centroid of Owada 4-chome, not from the property itself.

The building is a two-story wooden house built in March 2012 with a 4LDK layout (LDK approx. 17.1 tatami mats) and a total floor area of 104.96㎡, on 116.54㎡ of freehold land. According to the listing it was built by Hajime Kensetsu, the interior has been renovated, there is a parking space, and the house is vacant and available for immediate handover. The price is ¥29.8 million. No rent or yield is listed; the house is intended for owner occupation. In the photos, the land sits above a narrow channel-like passage outside the southwest boundary; the step is roughly 0.3–0.5m at the road end and up to about 0.85m at the far end, which is under 1m. The private road and the parking space are at the same level.

The assessed ratio is 80.5%. Because the road frontage is only 2.5m and the left side of the building front is hidden behind the neighboring house, we treat the lot as flag-shaped and deduct the access strip as 2.5m × 5.0m = 12.5㎡ (a minimum estimate), valuing the land on an effective area of 104.04㎡. If the strip is taken at a middle estimate of about 6m deep (15㎡), counted from the fence panels in the photos, the ratio is 79.3%; without deducting the strip it is 86.8%. The private road in front has no route price, so we adopted ¥150,000/㎡, the most common value on the local streets of Owada 4-chome. Using ¥145,000/㎡ would give 78.8%.

⚠️ The private road burden differs between listings: three SUUMO listings state 27.32㎡, the Tokyu Livable listing states 'none' with a surveyed area of 116.54㎡, and the athome listing leaves it blank. We treat the private road as a separate parcel and have not deducted it, for two reasons: counting 27.32㎡ as part of the 116.54㎡ would put the building coverage at about 63% based on the ground-floor area measured from the floor plan (approx. 56.5㎡), above the designated 60%; and the Tokyu Livable listing says 'none'. If the 27.32㎡ were deducted as part of the lot, the ratio would be 73.1% (66.8% if the access strip is also deducted). No lot plan is available, so whether the private road is a separate parcel or included in the lot has not been confirmed. The share of the private road, consent for passage and excavation, and the actual dimensions of the access strip need to be confirmed with the agent.
