How We Checked This Property
We traced every local block road in Kamiaokinishi 2-chome on the FY2026 route price map and checked the level of the lot against the road using the listing photos and GSI elevation data.
What We Could Not Confirm
- The road-access field in the listing is blank; the type, width and direction of the frontage road are not stated. If the road is narrower than 4 m, setback would reduce the usable lot.
- The street address is not disclosed, so we could not identify which road the lot faces. Block roads in the area range from 210,000 to 245,000 yen/m2; at the lowest band the assessed ratio is about 86.7%.
- The house is currently occupied and a deposit is mentioned, but no rent or yield is listed, so it is unclear whether it is tenanted or seller-occupied.
- Only one exterior photo is available; the level difference to the neighbors on the right side and at the rear is unconfirmed.
※ 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
A two-story wooden detached house built in October 2021 in Kamiaokinishi 2-chome, Kawaguchi, Saitama, a 20-minute walk from Nishi-Kawaguchi Station on the JR Keihin-Tohoku Line (29 minutes from Warabi Station). The site is in a quasi-industrial zone (60% building coverage, 200% floor area ratio) within the urbanization promotion area, land category residential, with freehold land.
The 105.59 m2 lot (about 31.94 tsubo) carries a 96.46 m2 4LDK (LDK of about 16 tatami and a 6-tatami Japanese room on the first floor, three Western-style rooms on the second floor) with one parking space. The house is currently occupied; a security deposit is mentioned but no rent or yield is listed (yield undetermined). The transaction is brokered and the handover date is negotiable.
For the land we used 240,000 yen/m2 (FY2026), the most common value among the local block roads across Kamiaokinishi 2-chome, and the listed lot area as is because no private-road burden is stated. The building is valued as a 4-year-old wooden structure (59 months elapsed) with 18 of its 22 statutory years remaining, giving an assessed ratio of about 93.7%. The same road segment was 220,000 yen/m2 in 2024 and 230,000 yen/m2 in 2025. Even at the lowest band in the block area (210,000 yen/m2) the ratio is about 86.7%, and treating the building as 5 years old, as one listing states, gives about 91.5%.
Points to note: the road-access field in the listing is blank, so the type, width and direction of the frontage road are unconfirmed. If the road is narrower than 4 m, setback would reduce the usable lot. The street address is not disclosed, so we could not identify which road the lot faces. Photos show the house fronting a paved road directly, with the parking slab at almost the same level as the road, but only one exterior photo is available and the level difference to the neighbors on the right side and at the rear is not shown. Distances to the drugstores and supermarket are from the listing; restaurant distances are straight-line distances from the block centroid.
