Japan is a nation of beauty and intrigue, filled with breathtaking vistas of towering mountains, iconic architecture, and renowned cities.

Microsoft partnered with Bing Maps, Gaya, and Asobo to build World Update 20, one of the largest Flight Simulator world updates to date.

Regions where new photogrammetry cities have been added include Hiroshima (1 AOI), Kyoto (1 AOI), Osaka (3 AOIs), Sapporo (2 AOIs), and Tokyo (16 AOIs). The update also comprises 67 points of interest, including: Osaka Castle, one of the most important historical locations in Japan; Akinada Bridge, a beautiful suspension bridge that spans the Seto Inland Sea; Shosanbetsu Observatory, an important astronomical observatory; Enoshima Sea Candle, a distinctive lighthouse and observation tower; and Fukuoka Tower, the tallest seaside tower in Japan.
