How We Checked This Property

With no listing photos and an address given as a lot number, we checked the valuation zones and route price bands of Owada 1-chome on the 2026 route price maps and multiplier table, and examined height differences within the district using GSI elevation data.

Locating the road price

Counting the local streets of Owada 1-chome on the 2026 route price map (sheet 40307), 155,000 yen/m² is the most common value (about 17 sections), and we use it as the representative value (leasehold ratio D). Including the adjacent sheets that cover parts of 1-chome (40303, 40308, 40311), local streets fall into bands of 145,000–165,000 yen/m²; arterial roads such as Prefectural Road Niiza-Wako (185,000 yen/m²) are not used. Even the lowest band, 145,000 yen/m², gives an assessed ratio of about 102.0%. The same road moved 150,000 (2024) → 155,000 (2025) → 155,000 (2026) yen/m².

Listing check

The "1-87-6" in the address does not match the residence-indication blocks of Owada 1-chome (1–28) and appears to be a land lot number. The map position on Rakumachi is only about 55 m from the GSI representative point of 1-chome, so we judged it to be a district-level position and did not use it. According to the 2026 multiplier table, Owada 1-chome is divided into three categories: a route price area, the project area of the Niiza Station North Exit Land Readjustment Project (valued individually), and an urbanization control area. The listing states an urbanization promotion area with designated zoning, so it is not in the control area. Even if it is inside the project area, the roads bordering that area are 160,000–185,000 yen/m², not below the representative value. A 16-minute walk from Niiza Station fits the northern part of 1-chome (blocks 24–28), about 1.0 km in a straight line from the station, and fits poorly with the readjustment area (about 0.6 km).

Effective land area

The private road burden and road access fields are blank, so the width of the front road and whether a setback is required are unknown. We therefore use the registered area of 128.65 m² as is. If it were a flag-shaped lot and an access strip of about 30 m² were excluded, the ratio would be about 93.3%; a setback of a few square metres for a road narrower than 4 m would still leave it above 100%.

Building valuation assumptions

A two-storey wooden house (total floor area 104.54 m²) built in June 2024, with 20 of the 22-year statutory useful life for wooden structures remaining. The building accounts for nearly half of the assessed value. With no exterior photos, the condition of the building and the exterior works has not been checked.

On-site check from photos

The Rakumachi listing has zero photos, and we could not find the same property on SUUMO, athome or Kenbiya. Instead we checked Owada 1-chome with GSI 5 m mesh elevation data: blocks 24–28 in the north are at about 12.7–13.7 m and block 21 at about 28.2 m, so a terrace escarpment with a height difference of about 14 m runs through the district. Because the position of the site is unknown, the height differences between the site and the road or neighbouring lots could not be measured. If the lot is on the slope side, there may be retaining walls or level differences.

What We Could Not Confirm

  • There are no site photos, so whether there are retaining walls and whether there is a level difference with the front road (including whether the site is reached by steps) have not been checked. A terrace escarpment with a height difference of about 14 m runs through Owada 1-chome, and a lot on the slope side may have retaining walls or level differences. An on-site check or an enquiry to the listing agent is needed.
  • Whether it is a flag-shaped lot, and whether it is not a row house attached to a neighbouring building, could not be checked because there are neither photos nor a lot plan. If it is a flag-shaped lot with an access strip of about 30 m², the assessed ratio falls to about 93.3%.
  • The building was built in June 2024, but with no exterior photos the condition of the building exterior and the exterior works has not been checked.
  • The address "Owada 1-87-6" does not match the residence-indication blocks (1–28) and appears to be a land lot number, so the position has not been identified. If it is inside the Niiza Station North Exit Land Readjustment Project area, there is no route price and it is valued individually, so the lot number and the area need to be confirmed.
  • The road access and private road burden fields are blank, so the width and type of the front road and whether a setback is required are unknown.

※ 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 listing has no photos at all, and we could not find the same property on SUUMO, athome or Kenbiya. As a result, we have not been able to check whether there are retaining walls, whether there is a level difference with the front road (including whether the site is reached by steps), whether it is a flag-shaped lot, whether it is a row house attached to a neighbouring building, or the condition of the building exterior. GSI elevation data show a terrace escarpment with a height difference of about 14 m running through Owada 1-chome, so if the site is on the slope side there may be retaining walls or a level difference with the road. In addition, the road access and private road burden fields are blank, so the width and type of the front road and whether a setback is required are unknown.

The address is listed as "Owada 1-87-6, Niiza", but the residence-indication blocks of Owada 1-chome are numbered 1 to 28, so "87" appears to be a land lot number, and the position of the site has not been identified. Besides areas with route prices, Owada 1-chome includes the project area of the Niiza Station North Exit Land Readjustment Project (valued individually, without route prices) and an urbanization control area. The listing states an urbanization promotion area with designated zoning, so it is not in the control area, but whether it is inside the readjustment project area is unknown. The listing gives a 16-minute walk from Niiza Station on the JR Musashino Line, which fits the blocks in the northern part of 1-chome (blocks 24–28), about 1.0 km in a straight line from the station.

The property is "Libre Fine Niiza Owada Phase 2", a two-storey wooden 4SLDK house (total floor area 104.54 m²) built in June 2024. The land is 128.65 m² on the register, freehold, land category residential, straddling a Category 2 Medium-to-High-Rise Exclusive Residential Zone and a Category 2 Residential Zone, with 60% building coverage and 200% floor-area ratio. It is leased and fully occupied, with projected annual rent of 2.136 million yen (178,000 yen per month) and a gross yield of 5.50%; the price is 38.8 million yen. The seller is Hajime Construction Co., Ltd., and a designated property management company applies. Nearby are 7-Eleven (Owada 1-chome, about 560 m), Beisia (about 760 m), and Nakau and CoCo Ichibanya (both about 360 m). Distances are straight-line distances from the centroid of Owada 1-chome; because the property's position has not been identified, actual distances may differ considerably.

The assessed ratio is about 105.3%. For the 2026 route price we use 155,000 yen/m² (leasehold ratio D), the most common value on the local streets of Owada 1-chome. Local streets in 1-chome fall into bands of 145,000–165,000 yen/m² (excluding arterial roads such as Prefectural Road Niiza-Wako at 185,000 yen/m²); even the lowest, 145,000 yen/m², gives about 102.0%, so the ratio stays around 100% whichever band applies. The same road was 150,000 yen/m² in 2024 and 155,000 yen/m² in 2025 and 2026. Built in 2024, the building has a long remaining useful life and accounts for about half of the assessed value. Even if it were a flag-shaped lot and an access strip of about 30 m² were excluded, the ratio would be about 93.3%. With no photos, the retaining walls, level differences, road access, whether it is a row house, and the position of the site need to be confirmed with the listing agent or on site.
