[Assessed 104.7%] Apartment building in Totsuka Ward, Yokohama, Kanagawa — 10 min from Odoriba Sta.

Kumizawa 2-chome spans five roadside-value map sheets. We obtained the coordinates of all 27 blocks from the Geospatial Information Authority and matched them against the block numbers on the maps. Every block that could be sold as housing carries 185,000 yen or more; the 145,000 yen figure applies only in front of a high school. We conservatively took 190,000 yen, the value on the district road serving the southern blocks that correspond to a 10-minute walk from the station. Even the lowest residential figure of 185,000 yen gives 102.0 percent.

The listing carries no site photographs at all. Examining the page HTML showed there is no photograph frame — they were not missed in retrieval, they were never posted. The same property could not be found on the other three sites, the seller's own website or in a web search. Retaining walls, steps, stair access, flagpole shape and shared walls are therefore all unjudged.

We measured elevation at all 27 block reference points in Kumizawa 2-chome using Japan's 1-metre-mesh data. The plateau to the north is fairly flat at 62.1 to 64.6 metres, but the south-east drops sharply from 58.3 to 45.3 metres, a difference of 19.3 metres across the district. The southern blocks corresponding to a 10-minute walk fall on that slope, so retaining walls or a step at the road are far from unlikely. The lot number is withheld, so the site itself could not be measured.

The notes state that both the floor area and building coverage ratios are exceeded, making this legally non-conforming. On 165.34 sq m of land the 264.41 sq m of floor area works out at about 160 percent against a designated 150 percent, so it cannot be rebuilt at the same size. Part of the land also carries a registered easement for a transmission line.
