One day, his wife, Tsumugi, gives him a camp circular. Naturally, I said that I couldn't go because of work, but Tsumugi, who was concerned about the eyes of the town and the women's association, seems to participate alone. That night, when I sent my wife off to see if there were a lot of people, she emailed me and informed me that there were only four participants. The radio waves are bad, and it is difficult to turn back for two nights and three days in the mountains ... I was told by a person in the town that it was an unofficial event.
