It's very warm here in Tokyo again. And, it would be warmer in the afternoon. Spring has come, and birds sing. But, many crazy old crackpots make turmoil around in my community. Most of them are divorced and abandoned by their families due to their own faults and responsibilities. Those criminals are a problem here in Japan, and it has been highlighted since the year of 2016. The rate of criminal of males beyond the age of 60 has been 13 times for these sixteen years. It is record-breaking in the criminal history of Japan. There are many analyses and descriptions that would explain why the specific age of male is statistically significant rather than other generations. However, any of them are not successful for giving a persuasive answer to the problem. But, it is true that our community has been much more dangerous than before here in Japan, that was once believed to be safe.
