Wildfires in Japan

295 fires over 200 hectares with a perimeter estimated by GWIS since 2016, adding up to 148,777 hectares burned across 129 municipalities.

Only fires of 200 ha or more get an entry: smaller ones are not in the lists or the entry totals, but they are in the GWIS yearly series.

These figures leave out 2 provisional pages, seen only as heat detections and still without a perimeter. They appear in the lists, marked.
