How We Checked This Property
Rather than reposting the listing as is, we checked the 2026 route price maps and seven exterior photos in the listing to confirm the representative route price, the level difference between the road and the lot, and the condition of the boundaries.
What We Could Not Confirm
- The northern and rear boundaries are hidden behind the building and do not appear in the photos, so the level difference with the neighbouring lots and whether there is any retaining wall there have not been confirmed.
- The listing's feature tags include "corner lot", but the road access field mentions only the 6.0 m-wide public road on the southeast side. Whether there is a second road, and its type, must be confirmed with the broker.
- The level difference from the road up to the garden (about 0.5-0.7 m) is an estimate from the number of steps and block courses in the photos, not a measurement.
- The address is published only down to Isobe 3-chome, without a lot number, so the route price of the road the lot faces has not been identified. We used 150,000 yen/㎡, the value of most local roads in the chome.
※ 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
This is a pre-owned detached house in Isobe 3-chome, Mihama Ward, Chiba City, Chiba. The nearest station is Kemigawahama on the JR Keiyo Line, an 18-minute walk. The listing's neighbourhood section gives these distances from the property: 7-Eleven Kemigawahama (Isobe 4-chome) 640 m, Yaoko Kemigawahama (Isobe 5-chome) 1,140 m, Naka-Isobe Park 310 m, Isobe Elementary School 590 m, Kaihin Hospital 610 m and Isobe Junior High School 620 m. The listing gives no restaurants, and because the exact position of the property is not published, we measured straight-line distances from the centroid of Isobe 3-chome to each OpenStreetMap position: Daily Yamazaki Chiba Isobe 2-chome about 410 m, the restaurant THE SURF OCEAN TERRACE inside Inage Seaside Park about 410 m, the soba restaurant Teuchi Soba Yamamoto about 560 m and an Italian restaurant-cafe (リストランテカフェ・アンリエチェリー) about 600 m.
The building is a two-storey reinforced concrete (RC) house with a 4LDK layout, built in March 2012 (14 years old), with a total floor area of 122.14 ㎡. In February 2026 the exterior walls and roof were repainted, the kitchen, bathroom, toilets, washbasin and water heater were replaced, and the wallpaper in every room was renewed. The land is 205.80 ㎡ (registered area) of freehold with no private road share or setback, and it fronts a 6.0 m-wide public road on the southeast side for 11.7 m. It is in a Category 1 Low-rise Exclusive Residential Zone with a 50% building coverage ratio and a 100% floor area ratio, and is subject to the Landscape Act. There is parking for two or more cars, and the house is vacant and available for immediate handover. ⚠️ The lot sits about 0.5-0.7 m above the front road, and three steps lead up from the roadside parking space to the garden (estimated from the photos at under 1 m).
The property is not listed as an income property, and no assumed rent or yield is given. We used the 2026 route price of 150,000 yen/㎡ (leasehold ratio D), which has risen about 11.1% over three years. As an RC building only 14 years old, the building carries a large assessed value, and land and building together give an assessed value of about 86.0% of the 68.8 million yen price, with the building accounting for nearly half of it. Note that the building's assessed value falls each year as it ages, and that the February 2026 renovation is not reflected in the assessment.
The area is a flat residential district on reclaimed land, and the front road is a 6.0 m-wide public road. ⚠️ However, while the listing's feature tags include "corner lot", the road access field mentions only the southeast side, and the northern and rear boundaries do not appear in the photos, so any level difference there has not been confirmed. The broker is Mitsui no Rehouse Shin-Kamagaya Center (Mitsui Fudosan Realty, general brokerage), and the listing was published on September 25, 2026.
