How We Checked This Property
We compared the Kenbiya, SUUMO and HOME'S listings for the same property and checked the 2026 route price map, the listing photos and GSI elevation data to confirm the location, the land area to assess and any level differences.
What We Could Not Confirm
- The listing does not explain the arrangements with the other buildings for passage over and maintenance of the 21.43 m² agreed passage.
- Whether the registered land category is still "field" or has been changed to "residential" differs between listings and needs to be confirmed.
- The rear boundary does not appear in any photo, so the presence and height of any retaining wall there could not be determined.
- The lot number is not disclosed and Oaza Kume is large, so the route price of the road the lot touches has not been identified. Within the estimated band values range from 110,000 to 140,000 yen/m², giving 88.5-97.8%.
- The yield is undetermined and no rent has been set, so rental income is not shown. The completion and handover date also differs by listing (end of April or June 2026).
※ 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 newly built detached house in Oaza Kume, Tokorozawa, an 18-minute walk from Tokorozawa Station on the Seibu Ikebukuro and Shinjuku lines. Nishi-Tokorozawa Station (Seibu Ikebukuro Line) is a 23-24 minute walk and Higashi-Murayama Station (Seibu Shinjuku Line) a 36-minute walk. It is Building 1 of the three-unit development "Tokorozawa Kume No. 21", in a Category 1 low-rise residential zone (building coverage 50%, floor area ratio 80%) with landscape and aviation law restrictions. Among nearby facilities, the supermarket Amaike With Kume (760 m), FamilyMart Tokorozawa Matsugaoka (680 m) and the Emiterrace Tokorozawa shopping complex (1,100 m) are distances from the property given in the SUUMO listing. The three restaurants are shown by straight-line distance from the reference point of Oaza Kume returned by the GSI address search, based on OpenStreetMap locations. All are in Tokorozawa.
The price is 38.9 million yen. The land is 143.09 m² (surveyed, freehold, no private road burden), and the building is a two-story wooden house (post-and-beam) with 95.58 m² of floor area, 3LDK plus a storeroom (LDK about 18 tatami, telework room about 3 tatami) and parking for two cars. The front road is a 4.2 m wide paved public road according to the SUUMO listing; the Kenbiya listing only says "one side" for road access, with no width or type. It has public water, public sewer and individual LPG, and is vacant and available immediately. A design housing performance evaluation has been obtained and a construction performance evaluation is scheduled. ⚠️ The completion date differs between listings (end of April 2026 on SUUMO, June 2026 on Kenbiya), and we adopted the earlier April 2026. ⚠️ The land category also differs: "field" on Kenbiya and HOME'S, "residential" on SUUMO. The yield is undetermined and no rent has been set.
Oaza Kume spans 11 sheets of the 2026 route price map, so we narrowed the location to an east-west band using the listed distances to schools and stations, and adopted 125,000 yen/m² (leasehold ratio D), the most common value on local streets in Oaza Kume. This street was 120,000 yen in 2024 and 2025 and 125,000 yen in 2026, up about 4.2% over two years. ⚠️ The 143.09 m² of land includes 21.43 m² of agreed passage for Building 1, which serves as access for the other buildings; we deducted it and assessed 121.66 m². Together with the new building, the assessed ratio is 93.1%; without the deduction it would be 100.0%. Even at 110,000 yen/m², the value of the neighboring band, it is 88.5%.
The photos show the front road and parking at the same level, with two or three steps up to the entrance. The boundaries with the neighbors on the left and right are low curbs at about the same level, but the rear boundary does not appear in any photo and has not been checked. Another broker's listing gives the building area as 102.44 m², but we adopted 95.58 m², which matches the sum of the first and second floors on the floor plan. Please confirm the arrangements for using and maintaining the agreed passage, the registered land category and the completion and handover dates with the broker before considering the property.
