Japan country watch

Exposure to Japan means watching the Bank of Japan and the yen, Tokyo's economic-security and subsidy decisions, earthquakes and typhoons that halt plants and ports, the ports of Tokyo, Yokohama and Nagoya, and the autos, electronics, machinery, chemicals and trading-house groups that anchor Asian supply chains. We read Nikkei, Asahi, Yomiuri, NHK and Toyo Keizai every morning.
