Reading the Nagareyama numbers
The ¥400K/m² median is the midpoint of 463 recorded home sales in Nagareyama between 2023Q2–2026Q1, and half of those sales fell between ¥250K and ¥522K per m². That is 405.8% above the national home median of ¥79K per m², measured across the 1,684 municipalities with enough recorded sales to publish one. Against that, 684 home listings were tracked as of Aug 2026, and their asking prices come to ¥465K per m² once each location counts once, 16.2% above what the recorded sales say. 18.4% of those listings have already been reduced at least once.
The asking figure takes a midpoint within each location before taking one across locations, so a single bulk listing cannot set it. Asking prices and recorded sales are also different properties measured at different times, so treat the gap as where negotiation starts, not as a discount anyone is offering.
