Japan Pilot Weather

Central Japan Weather briefing

The Japan Weather Agency (JMA) provides several charts, forecasts and documents for the aeronautical operations. Navigation inside all the documents could be difficult when you don’t know all the expressions, words and abbreviations used. Aim of the page is to present the documents, not to recall the traditional abbreviations used inside METARs, TAFs…

You should be able to find the charts on this page: link: http://www.data.jma.go.jp/airinfo/index.html[jma website]
