[Assessed 82%] Detached house in Kawaguchi, Saitama — 13 min from Hatogaya Sta.

A newly built detached house in Oaza-Sato, Kawaguchi, Saitama, a 13-minute walk from Hatogaya Station on the Saitama Rapid Railway. Arai-juku Station is also usable at 19 minutes on foot; completion is scheduled for December 2026. A beef-bowl restaurant is 53 m from the property, a convenience store 104 m and Aeon Mall Kawaguchi 557 m.

The land is 82.00 sqm by the register and the wood-frame three-storey 4LDK building has a floor area of 122.55 sqm. The land is freehold with no private-road burden, fronting a 4.0 m public road on the north side over a 7.8 m frontage. Zoning is quasi-industrial with a 60% building coverage ratio and 200% floor area ratio; the land category is residential and the terrain is flat. It has a 17.5-mat living-dining-kitchen and 4.5-mat, 6-mat, 6.5-mat and 10-mat western rooms, a 6 sqm balcony and parking for two cars. The house is under construction, with handover expected in late December 2026. The thumbnail on this page is the artist's impression from the listing, not a photograph of the finished building.

This property sits in a land-readjustment project area, so no inheritance-tax road price is published for it. Applying 120,000 yen/sqm — the lowest value in the surrounding published band — the land assessed value comes to 9.84 million yen and the newly built structure to 26.96 million yen, 36.80 million yen in total, an assessed ratio of 82.0%. That band minimum is tracked over three years and has risen 9.1% from 110,000 yen in 2024.

With the full 22 years remaining of the statutory life for wood construction, the building carries its assessed value in full. Please read the research notes on why the road price here is an estimate.
