How We Checked This Property
Rather than repeating the listing, we read the block roads on the 2026 road price map, deducted the flagpole strip from the plan, and checked the frontage in another site's exterior photos. The disclosure item is also recorded.
What We Could Not Confirm
- The nature and timing of the disclosure item are not in the listing and must be confirmed with the seller.
- The strip area (about 35 ㎡) is estimated from plan proportions; without the deduction the ratio is 118.7%.
- SUUMO gives the frontage as north-west 6 m while athome and HOME'S say south-west 6.0 m; we followed the plan note (Article 42-1-1 road, 6.03 m).
- The reason for two price cuts in just over two months is not given.
※ 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's other restrictions state "disclosure item present", but its content is not given. This site does not exclude properties with disclosure items, but the content must be confirmed with the seller. The lot is also a flagpole plot reached through a 3.0 m wide strip. The strip is drawn as part of the lot on the plan and lies within the registered 152.24 ㎡, so we read it as about 35 ㎡ (3.0 m by about 11.5 m) from the plan proportions and deducted it, giving an effective area of 117.24 ㎡. The plan has no dimensions, so the strip area is an estimate.
A used detached house in Higashi-Osawa 2-chome, Koshigaya, 15 minutes on foot from Kita-Koshigaya Station on the Tobu Isesaki Line. Price 23.8 million yen, wooden two-storey 4LDK built in May 2018, building 96.38 ㎡ and land 152.24 ㎡ (both registered), freehold. Category 1 mid-to-high-rise residential zone, 60% building coverage, 150% floor area ratio, no private road burden; it fronts a 6.03 m public road (Article 42-1-1) on the south-west with a 3.0 m frontage. Interior refurbishment (wallpaper in every room, house cleaning) was completed in June 2026, and the house is vacant with immediate handover.
We located the block from the address in the HOME'S listing (Higashi-Osawa 2-chome 34-12) and used the lower of the block roads around it, 97,000 yen/㎡. Land: 117.24 ㎡ effective area gives 11.37 million yen; the 8-year-old wooden building gives 13.49 million yen at 220,000 yen/㎡ × 96.38 ㎡ × (22 − 8) ÷ 22; total 24.86 million yen, an assessed ratio of 104.5%. Without deducting the strip (152.24 ㎡) it would be 118.7%. The 99,000 yen/㎡ road on the other side of the block gives 105.0%, so the conclusion does not change.
Saitama Sogo Jutaku Koshigaya also lists the same house on athome and HOME'S. In the two athome exterior photos the plot is flat and level with the road and neighbours, with no retaining wall, step or stair access. HOME'S history shows two price cuts from 25.8 million yen at release in June 2026 to 24.8 and then 23.8 million yen. Kita-Senju is about 30 minutes from Kita-Koshigaya by express and Ueno about 45 minutes.
