Sale prices

Source: Ministry of Land, Infrastructure, Transport and Tourism (MLIT), Real Estate Information Library (link to the Real Estate Information Library) — real estate transaction price information, collected by MLIT through a survey of buyers and processed so that individual properties cannot be identified. Used under the Public Data License (Version 1.0). Aggregated and processed by Japan Home Prices; not created by the Government of Japan.
Required notice (original Japanese): 「このサービスは、国土交通省の不動産情報ライブラリのAPI機能を使用していますが、提供情報の最新性、正確性、完全性等が保証されたものではありません」 — This service uses the API of MLIT's Real Estate Information Library, but the latest status, accuracy and completeness of the information provided are not guaranteed.
Method: medians by prefecture, municipality, ward and year. House = "residential land (land and building)" with residential use and up to 250 m² of floor space. Condo = "pre-owned condominiums" of 15–200 m², shown as price per m² × 70. Land = residential-area land only. Sales with special circumstances (auctions, related parties, private roads and others) are excluded. Building age = sale year − construction year.
MLIT adds new sales every quarter, so the latest year is incomplete.

US dollar figures use the monthly average of the European Central Bank (ECB) euro foreign exchange reference rates, cross-calculated to USD/JPY by Japan Home Prices (via the Frankfurter API). Source: ECB. Rounded to the nearest $1,000.
