How We Checked This Property

We counted the local roads in Mukaikogane 2-chome across three sheets of the 2026 route price maps, and checked the treatment of the private-road share and the height differences around the lot using the listing's lot plan, exterior photo and GSI elevation data.

Locating the road price

Mukaikogane 2-chome spans three sheets of the 2026 route price maps (map numbers 09268, 09271 and 09272), and its local roads range from ¥100,000 to ¥120,000/m². Five roads were at ¥110,000/m² and five at ¥120,000/m², an even split, so we took the lower value, ¥110,000/m² (leasehold ratio D), as representative. The arterial roads along the chome boundary, Prefectural Road Matsudo-Kashiwa Line (¥130,000 and ¥145,000/m²) and the road along the Joban Line (¥135,000/m²), were not counted. The map position in the SUUMO listing is near a ¥110,000/m² road on map 09271. On the same map the three-year history is ¥86,000/m² in 2024, ¥96,000/m² in 2025 and ¥110,000/m² in 2026. Even the lowest value in the chome, ¥100,000/m², gives an assessed ratio of about 81.5%, and ¥120,000/m² gives about 88.3%.

Effective land area

The private-road burden is listed as "4.12m² co-owned share (1/1)". On the lot plan the house lot (frontage 7.870m, rear 8.043m) and the road portion are drawn as separate shapes, so we judged them to be separate parcels and used the registered land area of 135.43m² as is. If the 4.12m² were part of the land area and had to be deducted, the usable land would be 131.31m² and the assessed ratio about 83.7%.

Building valuation assumptions

A wooden house completed in October 2022. The listing calls it three storeys, but the third level is a rooftop penthouse and sky balcony. The assessment uses the registered floor area of 99.36m²; at three years old, 19 of the 22-year statutory useful life for wooden buildings remain. It is marketed to owner-occupiers, and no yield is stated.

On-site check from photos

There is one on-site photo, of the exterior, which we examined enlarged. At the front (north side, designated road) the concrete parking area for two cars is level with the road, with only a gutter grating at the boundary. The west and east boundaries have foundations about 0.3–0.4m high topped with mesh fences, and the neighbours' paving and cars sit at almost the same level, so any retained height is about 0.3m or less. The entrance is only two steps up, so there is no stair access; the house stands apart from its neighbours and is not on a flag-shaped lot.

Other checks

The rear (south) side, which is not in the photo, was supplemented with GSI 5m-mesh elevation data (laser survey). Residential land near the SUUMO map position is 22.9–23.6m, the adjoining paddy field 22.4–22.7m and the surrounding roads 22.5–23.5m, so we estimate the difference from the paddy field and road to the south at around 0.5m.

What We Could Not Confirm

  • Only one exterior photo is published, and the rear (south) boundary is not visible. GSI elevation data suggest a difference of around 0.5m from the surroundings, but whether there is a retaining wall needs to be checked on site or with the agent.
  • Only "Mukaikogane 2-chome" is disclosed and the lot number is unknown, so the route price is a representative value (¥110,000/m²) from counting the local roads in the chome and may differ from the road the lot actually fronts. Values within the chome range from ¥100,000 to ¥120,000/m².
  • Whether the private-road share of "4.12m² co-owned share (1/1)" is a separate parcel from the 135.43m² land area is a judgment based on how the lot plan is drawn; it needs to be confirmed with the certificate of registered matters.

※ 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 pre-owned detached house in Mukaikogane 2-chome, Nagareyama. The listing gives walking times of 15 minutes from Minami-Kashiwa Station and 24 minutes from Kita-Kogane Station on the JR Joban Line, and 31 minutes from Shin-Kashiwa Station on the Tobu Noda Line. The zoning is Category 1 Residential (building coverage 60%, floor-area ratio 200%). The regularly shaped lot fronts a 4.5m-wide designated road (Building Standards Act Article 42-1-5) on the north side with a frontage of about 7.9m. According to the SUUMO listing, Lawson Nagareyama Mukaikogane 2-chome is 360m away, Belx Minami-Kashiwa 530m and Across Plaza Nagareyama (Matsumoto Kiyoshi) 830m.

The building is a wooden house completed in October 2022: two storeys plus a rooftop penthouse and sky balcony, making it three storeys, with a 4LDK layout. The building is 99.36m² and the land 135.43m² (both registered areas), freehold. It has parking for two cars side by side and a system kitchen with a dishwasher. The price is ¥39.8 million. It is marketed as a pre-owned home for owner-occupiers, and no yield is stated.

For the 2026 route price, the local roads in Mukaikogane 2-chome were evenly split, with five roads at ¥110,000/m² and five at ¥120,000/m², so we took the lower value, ¥110,000/m² (leasehold ratio D), as representative. It has risen about 27.9% over two years from ¥86,000/m² in 2024. Because the building is new and most of its statutory useful life remains, its assessed value is large, and the assessed ratio is about 84.9%. Even the lowest value in the chome, ¥100,000/m², gives about 81.5%, and ¥120,000/m² gives about 88.3%. ⚠️ The listing shows a private-road burden of "4.12m² co-owned share (1/1)". On the lot plan the house lot and the road portion are drawn as separate shapes, so we judged them to be separate parcels and made no deduction; if the 4.12m² were included in the land area and deducted, the usable land would be 131.31m² and the assessed ratio about 83.7%.

Only one on-site photo, of the exterior, is published. The concrete parking area at the front is level with the road, and the east and west boundaries have only foundations about 0.3–0.4m high topped with fences; there is no retaining wall of 1m or more and no stair access, and it is neither a flag-shaped lot nor a row-type building. ⚠️ The rear (south) boundary does not appear in the photo, so we supplemented it with GSI 5m-mesh elevation data and estimate the difference from the surroundings at around 0.5m, but it has not been confirmed on site. For nearby places, the distances to the three shops are those stated in the SUUMO listing. The restaurants are places confirmed in OpenStreetMap to be in Nagareyama, and their distances are straight-line distances from the centroid of Mukaikogane 2-chome (coordinates from the GSI address search).
