How We Checked This Property
Because the listing has no exterior photos, we checked the FY2026 road price map, two listings of the same property on other sites, and GSI elevation data to verify how the road price was chosen and the terrain around the lot.
What We Could Not Confirm
- There are no on-site photos, so neither a retaining wall nor any level difference to the road has been confirmed. With a terrace edge southwest of the estimated location, the height of any retaining structure along the boundaries needs to be checked on site or with the agent.
- Whether the lot is flag-shaped, whether the house is attached to a neighbour, and the condition of the exterior could not be confirmed from photos (the listing states a frontage of about 10.8 m).
- The lot faces a private road (about 4.0 m wide) on the south side, but the listing does not state whether a share of the road or consent for passage and excavation is included.
- The lot number is not disclosed, so the location was estimated from distances to nearby facilities. The road price used is the block's most common value of 125,000 yen/m²; at the lowest band of 115,000 yen/m² the ratio would be about 101.7%.
- The house is currently occupied, and the listing gives no indication of the rent or yield if it were let.
※ 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
⚠️ The listing photos show only a floor plan and nearby facilities; there are no on-site photos of the building exterior, the frontage road or the boundaries with neighbouring lots. Whether there is a retaining wall, any level difference to the road, and the condition of the exterior have not been confirmed. GSI elevation data shows a terrace edge where the ground drops about 4 m some 30–45 m southwest of the estimated location; if the lot sits on this edge, there may be a retaining wall along a boundary. The lot number is not disclosed, so the location was estimated from the listed distances to nearby facilities. Please confirm the site conditions with the agent before considering a purchase.
This is a pre-owned detached house in Sakuracho 5-chome, Kawaguchi, a 12-minute walk from Araijuku Station on the Saitama Rapid Railway Line. Built in October 2024, it is a two-storey wooden house with 124.0 m² of floor area on a 260.16 m² freehold lot, in a Category 1 low-rise exclusive residential zone (60% building coverage, 100% floor area ratio). The 5LDK layout is designed for two households, with a bathroom and toilet on each floor and a mini kitchen on the second floor. Parking is available for two standard cars and one light car.
The asking price is 53.8 million yen. The house is currently owner-occupied and no rent or yield is listed. The FY2026 road price is 125,000 yen/m², the most common value among the local roads in the block, up about 8.7% from 115,000 yen/m² in 2024. The assessed land value is about 32.52 million yen and the two-year-old building is assessed at about 24.80 million yen, for a total of about 106.5% of the price. Even at 115,000 yen/m², the lowest band in the block, the ratio would be about 101.7%.
The lot faces a private road about 4.0 m wide on the south side, with a frontage of about 10.8 m. The listing does not state whether the lot includes a share of the private road or whether consent for passage and excavation has been obtained. The assessed value leaves a comfortable margin, but the retaining wall and level questions that the photos could not answer, and the rights to the private road, should be checked before considering a purchase.
