How We Checked This Property
To check whether a rear retaining wall could exist, we compared pre-development ground with the front road using GSI 5 m elevation data, and examined Unit 3 with SUUMO photos and the lot plan for the same development and the 2026 road price map.
What We Could Not Confirm
- ⚠️ There may be a retaining wall along the rear (west) boundary, and its height is unconfirmed (estimated at roughly 0–1.1 m from elevation data). Whether it exists and how high it is need to be checked on site or with the agent.
- Excluding the larger 9.31 ㎡ of garage space included in the floor area gives an assessed ratio of about 79.1%, and taking JPY 120,000/㎡ for the cul-de-sac branch road south of the site also gives about 79.1%.
- 154 kV and 66 kV transmission lines run close to the south of the site. The listing does not mention high-voltage lines overhead, and whether they pass over this lot is unconfirmed. If they do, the assessed ratio overstates the real value.
- The lot number is not disclosed, so the site's position outside the Sato Land Readjustment Project area and the frontage road price (JPY 140,000/㎡) were judged by estimating its location from the road price map and map coordinates. If the area is extended to the part of Oaza Sato on the adjacent map (28124), the most common value may become JPY 135,000/㎡, in which case the assessed ratio would be about 82.5%.
- The Kenbiya road-access field is blank; the frontage on the roughly 7 m public road to the east and the absence of a private-road share were confirmed from the SUUMO lot plan and road field.
※ 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 Unit 3, there may be a retaining wall along the rear (west) boundary, and its height has not been confirmed. GSI elevation data (5 m mesh) show the pre-development ground about 0.4–1.0 m below the front road, while the photos show the current site at road level, so the site appears to have been raised with fill. In that case we estimate a retaining wall of roughly 0–1.1 m could exist at the rear boundary toward the Shiba River embankment, but no photo shows the rear, and a 5 m mesh cannot resolve a step of about 1 m. This site does not list properties with a retaining wall holding back 1 m or more of earth, so whether there is a rear retaining wall and how high it is need to be checked on site or with the agent.
Unit 3 of a four-house new development in Oaza Sato, Kawaguchi, an 11-minute walk from Hatogaya Station on the Saitama Rapid Railway Line. The price is JPY 45.8 million for 102.38 ㎡ of land (freehold, residential land category, no private-road share) and a two-story wooden 3SLDK house of 108.88 ㎡, scheduled for completion in October 2026 (currently unfinished), with handover in late November 2026; the building confirmation number is 26UDI1W-Ken-03469. It fronts a public road about 7 m wide on the east and has a built-in garage for one car and an LDK of over 18 tatami. It is in a Category 1 residential zone (building coverage 60%, floor area ratio 200%), with restrictions including the River Act (the site adjoins the Shiba River embankment) and the Act on Regulation of Residential Land Development and Specified Fill. Kenbiya lists it under the "detached rental house" category, but it is a newly built house for owner-occupation, and no yield or expected rent is given.
The assessed ratio is about 83.6%. On 2026 road price map sheet 28113, both the embankment road the site fronts and the most common value on local streets in the surrounding area are JPY 140,000/㎡ (JPY 125,000 in 2024 → 135,000 in 2025 → 140,000/㎡ in 2026). The development lies outside (south of) the Sato Land Readjustment Project area, where road prices are published. If the area is extended to the part of Oaza Sato on the adjacent map (28124), the most common value may become JPY 135,000/㎡, in which case the assessed ratio would be about 82.5%. ⚠️ On the other hand, excluding the larger 9.31 ㎡ of the 7.27–9.31 ㎡ garage space included in the floor area brings the ratio down to about 79.1%, and taking JPY 120,000/㎡ for the cul-de-sac branch road south of the site also gives about 79.1%.
⚠️ 154 kV and 66 kV transmission lines run close to the south of the site, and a pylon and wires appear in the front-road photo. Aerial photos suggest the wires pass at least about 35 m south of Unit 3, but the listing does not mention high-voltage lines overhead and whether they pass over this lot is unconfirmed. If they do, the assessed value overstates the real value. Summit Store Hatogaya Ekimae is 797 m away and Yaoko Kawaguchi SKIP City 844 m (distances from the SUUMO listing); distances to Co-op Mirai and the restaurants are straight-line distances from the development coordinates shown by the listing source (LIFULL HOME'S), per OpenStreetMap.
