How We Checked This Property
Rather than reprinting the listing, we traced every district road in Oaza Angyo-Jirin across seven 2026 route-price map sheets, checked the level difference and the position relative to the expressway in the SUUMO listing's road photos, and recorded the power-line restriction as stated.
What We Could Not Confirm
- The exact position and extent of the roughly 50 sqm under the power lines is not shown in the listing; how it affects building or parking layout needs confirmation on site or with the broker.
- The ground-floor hair-salon space is unregistered and its area and structure are not stated.
- A sewer pipe is connected to the site but the house currently uses a septic tank; the need for and cost of connection work are not stated.
- No lot number is given; the route-price location relies on the listing's coordinates and the expressway viaduct seen in the photos. If the site were east of the expressway the band would be 105,000 yen and the ratio 75.5%.
- Arrangements for managing the co-owned public-road parcels (1/26 shares) are not stated.
※ 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 detached house built in 1969 in Oaza Angyo-Jirin, Kawaguchi City, a 12-minute walk from Araijuku Station on the Saitama Rapid Railway. The neighbourhood lies west of the Shuto Expressway Kawaguchi Line and south of the Tokyo Gaikan Expressway; a Seiyu supermarket, a 7-Eleven and Angyo-Jirin Kami Park are within about a five-minute walk, and Jirin Elementary School is about 550 m away. Trains from Araijuku run through onto the Namboku Line into central Tokyo without a change.
The land is a flat, regular plot of 129.49 sqm (registered) fronting a 4 m public road on the south-east for 16 m. The building is a two-storey wooden 4DK with a registered floor area of 45.76 sqm, plus an unregistered hair-salon space on the ground floor. Freehold, category-2 residential zone (60% coverage, 160% floor-area ratio), city gas. The house is vacant and handover is by negotiation.
For the assessment we traced every district road in Oaza Angyo-Jirin across seven route-price map sheets for 2026 and took the most frequent band, 120,000 yen/sqm (120D). The land alone comes to about 15.54 million yen, 86.3% of the 18 million yen price. The 57-year-old building is beyond its statutory life and is not valued. The same band rose 5,000 yen a year from 110,000 (2024) to 115,000 (2025) and 120,000 (2026). The block the property sits on is likely in the 130,000-140,000 band, which would give 93-100%.
Note: about 50 sqm of the site lies under high-voltage power lines, where building and bamboo planting are prohibited to protect the lines. Following our assessment rules we did not deduct this area, so the usable land is smaller than the valuation suggests; deducting it brings the ratio down to about 53%. The co-owned shares in ten public-road parcels (1/26 each, 40.65 sqm in total) are treated as separate parcels. A sewer connection exists on site but the house currently uses a septic tank, and together with the unregistered salon space these are points to confirm before purchase.
