From Daily Life - 89: Tracing back in time

 To mark the 80th anniversary of the end of the Pacific War, I compared the 80 years after the defeat with the 80 years before, which I introduced on my homepage two months ago. The prewar period, a time of consecutive wars, and the postwar period of continued peace were completely different eras. There are many other ways to contrast eras by tracing back in time.
 As a person, I have lived for 94 years since my birth. However, as shown in the picture above, if we place a time mirror at the year of my birth, we can imagine my life in the mirror tracing back in time as time passes. In this way, my real life is reflected to a life in mirror spanning 1837–1931. What kind of era was that?
 My life in mirror dates back to 1837 (Tenpo 8). This year the Oshio Heihachiro Rebellion occurred. By then, cold weather and poor harvests had caused continued hardship, and the repeated arrival of foreign ships had confused the people and deepened distrust of the shogunate's rule. Ohira Heihachiro raised an army to save the common people suffering from famine, but although the rebellion was quickly suppressed, it had caused a great deal of damage to the shogunate's prestige.
 Subsequently, foreign demands for opening this country grew stronger, and in 1854, Commodore Perry arrived in Shimoda with seven black ships, leading to the signing of the Treaty of Peace and Amity between Japan and the United States. In 1858, the shogunate launched the Ansei Purge to stifle anti-shogunate movements, executing patriots such as Hashimoto Sanai and Yoshida Shoin one after another.
 However, anti-shogunate forces, seeking to expel foreigners and restore imperial rule, only grew stronger, and the following decade leading up to the dawn of the Meiji era was marked by turmoil that could be described as a civil war. It was a turbulent decade that produced many historic dramas, including the battle between the Choshu clan and the French-Dutch fleet, the Anglo-Satsuma War, the Kinmon Incident between the Tokugawa shogunate and Choshu, the secret Satsuma-Choshu Alliance brokered by Sakamoto Ryoma, and the Boshin War that brought the Edo period to an end.
 A new era began in 1868 with the accession of Emperor Meiji. In my life in mirror I was 31 years old in the prime of my working life, and might wish to join the great reforms of the Meiji Restoration.
 My life in mirror experienced 11 eras—Tenpo, Koka, Kaei, Ansei, Man'en, Bunkyu, Genji, Keio, Meiji, Taisho, and Showa, while real life has experienced only three—Showa, Heisei, and Reiwa. The worlds of two lives are so different that it's difficult to find common ground.
 Everyone can see that technological progress has completely changed the world we see. But if I were asked what the most valuable change is for me, I would say it is the respect for human rights and the advancement of equality. I would be much happier living in the world we live in now.
 Looking at the picture above, the Tokugawa era doesn't seem like something from the distant past, but rather feels much closer to me. What a long time I've lived!
