[Assessed 88%] Detached house in Sakado, Saitama — 10 min from Sakado Sta.

The address is published only to the town name, and the coordinates in the listing are the stations', not the property's. We therefore obtained the coordinates of all 43 block reference points in Nakatomi-cho from the Geospatial Information Authority and triangulated using the three stated distances — 450 metres to the drugstore, 650 to the supermarket and a 10-minute walk to the station — narrowing the position to the north-east of the district with a residual of 114 metres. We took the 89,000 yen on the district road serving those blocks. Even the lowest in the candidate zone, 75,000 yen, gives 81.4 percent.

The remarks note a shared-ground share of about 1 sq m, but the listing alone does not say whether it sits inside the stated 100.01 sq m or on a separate lot. Since this is a corner plot, a cut corner — that is, road land — cannot be ruled out, so we deducted the 1 sq m conservatively. With the deduction the ratio is 88.0 percent; without it, 88.5 percent. Either way it is well above 80 percent.

We enlarged and checked two exterior photographs and one of the entrance. The concrete parking area in front runs on at much the same level as the road, with no step and no stairs. The planter wall along the front is about two courses of decorative block, which we put at 0.3 to 0.4 metres against the outdoor unit and the front door in the same frame. The mesh fences on the west and south boundaries are see-through and retain no soil, with the ground at the same level either side. Japan's 5-metre-mesh elevation data gave 28.3 to 29.7 metres across 30 measured points.

Against the 22-year statutory service life for timber the building is 12 years old, so ten years of value remain. The building accounts for 52 percent of the assessment. Built in 2014, it comes with a system kitchen, reheating bath function, two toilets and warm-water washing seats.
