Kirk here with more sad news. There was a major fire in Yamaga, not too far from Yachiyoza, the Toro Museum, and other places of historic and cultural significance. Fortunately, no one seems to have been hurt and none of those iconic facilities were directly affected.
The aerial image of the fire is from the following news page, on which you can see a video:

What I saw in the video (including a simple map) helped me find the location of the fire on Google maps. I’ve added a screenshot of the Google map I looked at with a little clipart fire image to show which part of the downtown area burned.
