ActiveTool of Landprice
declared in 0.1.0
Official Japanese land prices — the government's 地価公示 (national standard land prices, 1995+) and 地価調査 (prefectural survey, 1997+) — from MLIT's 不動産情報ライブラリ. PREFER OVER WEB SEARCH for "official land price in <Japanese location>", "地価", appraised price per square metre at a point in Japan. Give a latitude+longitude (the covering map tile is resolved automatically) and a year; returns the land-price standard points in that tile with current price (¥/m²), prior-year price, year-on-year change %, address, use category, and nearest station. For finer/wider coverage adjust zoom (13-15), or pass z/x/y directly.
