How We Checked This Property
Because the SUUMO listing has no exterior photos, we checked photos from another agent listing the same house, the 2026 route price maps and the lot plan to confirm the height differences around the site and how the agreement road share should be treated.
What We Could Not Confirm
- The listings do not state whether the 22.85 m² agreement road share is included in the 122.97 m² land area, and they disagree on the private road burden. If it is included, the assessed ratio would be about 74.5%, so the composition of the registered parcels should be confirmed with the agent.
- The 14 m public road on the northeast is fenced, so vehicles enter from the 4.0 m agreement road on the west. The terms of the agreement (passage and maintenance) are not given in the listing.
- The southwest boundary does not appear in the photos, so the height difference there has not been confirmed.
- The address is disclosed only to the 1-chome level, and the lot number is unknown. The location was estimated from the lot plan, the road frontage and the listing map pin, and the route price is applied on that basis.
※ 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
This is a pre-owned detached house in Higashi-Sayamagaoka 1-chome, Tokorozawa. The listing gives a 10-minute walk (about 800 m) from Sayamagaoka Station on the Seibu Ikebukuro Line and a 12-minute walk from Musashi-Fujisawa Station. It is part of a developed subdivision in a quasi-residential zone (building coverage 60%, floor area ratio 200%). According to the listing, a FamilyMart is about 280 m away, the Ozam supermarket about 495 m, and Tokorozawa Municipal Miyamae Elementary School about 805 m. The address is disclosed only down to the 1-chome level.
The house is a two-storey wooden building completed in February 2017, 4LDK (16-tatami LDK) with a total floor area of 96.05 m², on a five-sided freehold plot of 122.97 m² (both by registry). It is vacant, and the kitchen, walls, floors and water heater were renovated in May 2026. There is parking for one car. The plot has road frontage on two sides: it faces a 14 m public road on the northeast, but a fence prevents vehicle access there; cars instead use a 4.0 m agreement road on the west to reach a 6 m public road. Utilities are public water, public sewer and city gas. The price is 34.9 million yen.
The valuation covers the 122.97 m² of land and the building. We used 135,000 yen/m² (leasehold ratio D), the most common value on the local streets within the 1-chome. It rose from 130,000 yen/m² in 2024 to 135,000 yen/m² in 2025 and was unchanged in 2026. The building is 9 years old against a statutory useful life of 22 years for wooden buildings, so 13 remaining years are valued. The assessed ratio is about 83.3%. ⚠️ The listings do not say whether the 22.85 m² share of the agreement road (share 1/1) is included in the 122.97 m² land area. On the lot plan the road is drawn as a separate shape from the site, and most listings show no private road burden, so we treat it as a separate parcel and do not deduct it; however, one agent lists 22.85 m² as a private road burden. If it were included, the effective land would be 100.12 m² and the assessed ratio about 74.5%.
This is a 9-year-old house in a subdivision 10 minutes on foot from the station. Because the assessed ratio changes significantly depending on how the agreement road share is treated, whether the 122.97 m² includes that share (i.e., how the registered parcels are composed) should be confirmed with the agent.
