I revisited the Akagi village in Tanimura. I think the largest mansion, which looks like an old folk house, belonged to the Watanabe family, who pioneered this area. I learned about Mr. Watanabe from the monument, but it was damaged so I could only read part of it.
I've seen the display version of "Home of the Stars" in several places, and it seems that the stars can be seen more beautifully.
There was a house a little far from this area, but it seems like there were still people living there, so it doesn't seem to be an abandoned village yet.
