How We Checked This Property
The Kenbiya listing had only two photos of schools, so we checked Unit 2 against the SUUMO photos and lot plan for the same development, the 2026 road price map and GSI elevation data.
What We Could Not Confirm
- 154 kV and 66 kV transmission lines run 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 rear (west) borders the Shiba River embankment; whether there is a retaining wall at the rear boundary, and how high it is, cannot be confirmed from the photos.
- 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 lot-number notes on the road price map and map coordinates. The most common value across southern Oaza Sato is JPY 145,000/㎡, and the cul-de-sac branch road south of the site is JPY 120,000/㎡.
- The Kenbiya road-access field is blank; the frontage on the roughly 7.0 m public road to the east and the absence of a private-road share were confirmed from the SUUMO lot plan and road field. The lot plan shows five lots, while the sale is listed as four houses.
※ 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
Unit 2 of a four-house new development in Oaza Sato, Kawaguchi (marketed on SUUMO as "Meldia Sato"), an 11-minute walk from Hatogaya Station on the Saitama Rapid Railway Line. The rear (west) of the site borders the Shiba River embankment, and the front faces a public road about 7.0 m wide on the east. It lies in a Category 1 residential zone (building coverage 60%, floor area ratio 200%) within the urbanization promotion area, and the listing names restrictions under the Landscape Act, the River Act (the site adjoins the Shiba River embankment), shadow regulations, an Article 22 fire-prevention zone and the Act on Regulation of Residential Land Development and Specified Fill. Summit Store Hatogaya Ekimae is 797 m away and Yaoko Kawaguchi SKIP City 844 m (both distances as given in the SUUMO listing).
The price is JPY 44.7 million for 102.73 ㎡ of land (freehold, residential land category, no private-road share) with a two-story wooden 4LDK house of 110.96 ㎡ under construction. Completion is scheduled for October 2026 and handover for late November 2026; the building confirmation number is 26UDI1W-Ken-03468. The ground floor has a built-in garage for one car, and the house has an LDK of about 18 tatami, a south-facing balcony, a dishwasher and a bathroom dryer, with city gas and public water and sewerage. Kenbiya lists it under the "detached rental house" category, but it is in fact a newly built house for owner-occupation, and no yield or expected rent is given.
The assessed ratio is about 86.8%. We used JPY 140,000/㎡, the 2026 road price of the embankment-side road the site fronts, from road price map sheet 28113. JPY 140,000 is also the most common value on the local streets around the development (south of the land readjustment area), and the price rose from JPY 125,000 (2024) to 135,000 (2025) and 140,000/㎡ (2026), up 12.0% in two years. The northern part of Oaza Sato is the Sato Land Readjustment Project area and has no road prices, but this development lies outside it to the south, where road prices are published. Counting all of southern Oaza Sato, the most common value is JPY 145,000/㎡; a cul-de-sac branch road south of the site is JPY 120,000/㎡. The floor area includes 7.27–9.31 ㎡ of garage space; excluding the larger 9.31 ㎡ gives about 82.2%.
⚠️ 154 kV and 66 kV transmission lines run south of the site and cross the Shiba River; a pylon and wires are visible in the front-road photo. 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. ⚠️ Toward the Shiba River embankment at the rear (west), the photos show only a grassy slope, but no photo shows the rear boundary head-on, so whether there is a retaining wall and how high it is remain unconfirmed. Distances to Jason and the restaurants are straight-line distances from the development coordinates shown by the listing source (LIFULL HOME'S), per OpenStreetMap.
