If you are wondering which Japanese stock to be invested at the market downturn, I would suggest this, AEON. In March 2011, most of Japanese had to stay at home due to the radiation and many Japanese tried to buy everything they need as many as possible. The same excess purchase has been seen here in Japan after the Corona spread, and AEON looks getting prepared for those who are anxious and buy everything they need until they feel comfortable. The notice said each customer can buy 10 boxes of toilet paper. AEON looks very quick and is caching the demand at the best timing.
