How We Checked This Property
Because the lot number is not disclosed and road access is not listed, we counted every local road price in Kitasuna 6-chome on the 2026 route price map to see how the valuation changes depending on which road the lot faces, and checked the exterior photo and listing history.
What We Could Not Confirm
- The type and width of the road access, and whether the lot faces a road recognized under the Building Standards Act (i.e., whether the house can be rebuilt), are not listed. Because the price is below the route-price land value, it should be checked whether restrictions apply such as no rebuilding, no private road share, a flag-shaped lot or a setback.
- Zoning, building coverage ratio, floor area ratio and fire-prevention designation are blank in the listing.
- The lot number is not disclosed, so the route price of the road the lot faces (¥290,000–430,000/m² within Kitasuna 6-chome) has not been identified.
- The road in front is not visible in the photos, so the height difference with the road and whether the gravel path on the right is a narrow access strip (flag-shaped lot) cannot be determined.
- The lease terms (rent breakdown, lease period, etc.) and the difference in layout descriptions (4DK vs. 3LDK or larger) cannot be read from the listing and should be confirmed along with the surveyed area.
※ 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
⚠️ For this property, the road access, zoning, and building coverage/floor area ratio fields are blank on both Kenbiya and Rakumachi, so we could not confirm the type or width of the road in front or whether the house can be rebuilt. The road in front does not appear in the exterior photo either. The price is below the land value based on route prices, which could point to restrictions not shown in the listing, such as the house not being rebuildable, no share in a private road, a flag-shaped lot with a narrow access strip, or a required setback. None of these has been confirmed, so we cannot say that any of them applies.
⚠️ On Rakumachi the listing was registered on March 23, 2026 and updated on September 23, so it has been on the market for about six months since it first appeared (Kenbiya registered it on September 23). The lot number is not disclosed, so the route price of the road the lot actually faces has not been identified; we used ¥390,000/m², the most common value among local roads in Kitasuna 6-chome, as the representative figure.
This is a used detached house in Kitasuna 6-chome, Koto Ward, a 13-minute walk from Ojima Station on the Toei Shinjuku Line. The price is ¥29.8 million for 85.86 m² of land and an 80.31 m² two-story wooden house (49.57 m² on the first floor, 39.74 m² on the second), built in September 1989, with a 4DK layout (described differently across listings); both land and building are freehold. It is sold with a tenant in place (owner change), with an expected yield of 7.24% and expected annual rent of ¥2.16 million. The only photos are one exterior shot and a floor plan; the exterior shows a detached two-story wooden house (not a row house) on flat ground with no retaining wall visible. Whether the gravel path on the right is a narrow access strip cannot be determined from the photo.
The building is 37 years old and past its statutory useful life, so it is valued at ¥0 and only the land is assessed. Even if the lot faces the lowest-priced road in the area, ¥290,000/m², the assessed ratio would be 83.6%. Kitasuna is flat lowland along the Arakawa River. Distances to nearby places are straight-line distances measured with map data (OpenStreetMap) from the centroid of Kitasuna 6-chome, not from the property itself. The listing is handled by Rita Fudosan Co., Ltd. as the agent.
