Why Tokyo-twentyfive?

This blog is TOKYO-TWENTYFIVE because (1) it has been 25 years since I lived in Tokyo and (2)  we are currently in the Year Heisei 25.  The Japanese count their years according to each emperor's rule.  The current Emperor Akihito came to power 25 years ago, when his father, Emperor Hirohito, died on January 7, 1989.  Each era is given a specific name.  Under Emperor Hirohito, the period was called Showa. This period is Heisei.
