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!
