On Tuesday (I first wrote “Monday” but Tuesday is correct) the 26th, the PM2.5 level for Arao was 82 – more than double the recommended upper limit of 35. The government is telling people to stay inside when levels are double the limit of 35 but the problem is that it’s hard to know the levels in advance. By the way, when Arao reached it’s high, Mashiki (near Kumamoto City) was 51 – well over the upper limit. http://taiki.pref.kumamoto.jp/kumamoto-taiki/taikiHourItem/020/taikiHourItemvalueindex.htm http://www.pref.kumamoto.jp/soshiki/43/kankyoutaikiosen.html
