How We Checked This Property
Rather than taking the listing at face value, we traced every local road in Aihara 4-chome on the 2026 rosenka map, checked road access and level differences in the Kenbiya and SUUMO photos and plot plan, tested the private-road share, which the three sites treat differently, against the floor-area ratio, and also show the figure with the deduction applied.
What We Could Not Confirm
- The listings differ on whether the 34.21 sqm private-road share is inside or outside the 121.27 sqm land area. We treat it as outside (no deduction, 90.9%) based on the floor-area ratio, but deducting it would give 79.3%, so this is a borderline case where the interpretation changes the conclusion. Confirmation with the broker is recommended.
- The classification of the 4.5 m private road to the east (designated road or Article 42-1-2 road) and whether passage and excavation consent exists are not stated. The lot abuts the 4 m public road to the north, so road access for rebuilding is satisfied on the public-road side, but the terms of use of the private road need checking.
- The 97.65 sqm floor area slightly exceeds the 80% floor-area-ratio ceiling of about 97.0 sqm; whether the listed area includes space not counted toward the ratio (such as attic storage) cannot be determined from the listing.
- The lot number is not disclosed, so the location is estimated from the listing's facility distances (nursery 64 m, elementary school 270 m). The site is in a regulated residential land development area, and whether there is a level difference at the rear of the lot not shown in the photos needs an on-site check.
- Kenbiya lists the house as a rental house, but no expected rent or yield is 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
A newly built detached house in Aihara 4-chome, Midori Ward, Sagamihara, Kanagawa, a 19-minute walk (about 1,463 m) from Aihara Station on the JR Yokohama Line. Hashimoto Station (Keio Sagamihara Line / JR Yokohama Line) is a 32-minute walk. The listing cites Aihara Nursery School (64 m), Aihara Elementary School (270 m), 7-Eleven Sagamihara Nihonmatsu 4-chome (410 m) and Shinmachi Kindergarten (716 m). The site is in a Category 1 low-rise residential zone (building coverage 50%, floor-area ratio 80%) and is subject to an Article 22 fire-prevention designation, the Sagamihara landscape plan, the Cultural Properties Protection Act, the residential land development regulation (regulated development area), a height limit and shadow regulations.
This is Building 1 of the two-house development "Aihara 5th Phase": a two-story wooden 4LDK with shoes-in closet completed in July 2026, floor area 97.65 sqm on 121.27 sqm of land; building confirmation No. 25UDI1S-14888. Freehold, no setback required. It is a corner lot on a 4 m public road to the north and a 4.5 m concrete-paved private road to the east (shared by seven lots, co-ownership share 237 sqm x 1/7 + 2.19 sqm x 1/6 = 34.21 sqm), so it abuts a public road directly. No built-in garage; two open parking spaces. Kenbiya lists it as a rental house but gives no rent or yield; it is effectively a new single-family home. The same property appears on SUUMO (43.99 million yen) and LIFULL HOME'S (42.99 million yen, published 14 June 2026); we use the lowest price, 42.99 million yen.
For the assessed value we traced every local road in Aihara 4-chome on the 2026 rosenka map (sheet 78018) and took the most frequent value, 145,000 yen/sqm (leasehold ratio symbol D); the 4 m public road to the north is in this band. Land comes to about 17.58 million yen and the brand-new building to about 21.48 million yen, a total of about 39.07 million yen or 90.9% of the 42.99 million yen price. ⚠️ The listings disagree on the 34.21 sqm private-road share: SUUMO says it is "included in the land area", whereas Kenbiya by definition shows land area net of private road and HOME'S lists the same 121.27 sqm without a private-road note. Because 97.65 sqm / 121.27 sqm = 80.5% almost exactly matches the 80% floor-area ratio, we treat 121.27 sqm as the net plot and do not deduct. ⚠️ If 34.21 sqm were deducted as included, the effective plot would be 87.06 sqm and the ratio would fall to 79.3%. Unlike the adjacent Building 2 (88.2% even after deduction), this is a borderline case where the interpretation changes the conclusion.
Four Kenbiya photos plus SUUMO's site photo and plot plan show both the north public road and the east private road level with the lot, with no step other than the two porch steps (about 30-40 cm). The low block wall in front (two or three courses, about 40-60 cm) is a decorative wall with the same ground level on both sides, not a retaining wall; there is no level difference with the neighbors to the west or south (Building 2), and no retaining wall, stepped access or slope is visible. It is a regular lot, not a flag lot and not a row house. Vacant, immediate handover, brokered by ME PLUS Machida. The adjacent Building 2 (38.99 million yen, assessed 100.9%) is offered by the same seller at the same time and is 4 million yen cheaper with a higher ratio.
