This map is hard to make out (particularly if you don’t read Japanese) but it shows the current situation in the Kumamoto City area. Many of the camera marks on the map are on the Shirakawa River, so if you know where the Shirakawa is, that may help you make sense of the map. The red triangles indicate waterways that have reached the flood level. (They may not have flooded yet, but they are very close to doing so.) One of them is the little waterway that runs by the Nishikigaoka Park in Kengun – a favorite jogging spot of mine. As far as I can tell, major rivers such as the Shirakawa are still OK but smaller waterways are having trouble handling the sudden surge. Be careful around such places.
