This top page is to transmit the proof that I am still alive and enjoying
retired life, mainly to my relatives, friends and former students. A story
or an event is selected from daily life and my thoughts and experience
are introduced.

Eighty years have passed since 1945 when Japan defeated in the Pacific
War. The decade leading up to 1955 was considered the period of rebirth
as Japan emerged from turmoil and established the foundation of a peaceful
nation under a constitution that renounced war. In the successive 35 years
leading up to 1990, rapid economic growth continued, and Japan was once
called "as Number One." However, the economy bubble eventually
burst and Japan entered a long period of stagnation. Over the past 35 years,
while growth as measured by GDP has been slow, Japan has worked hard to
build a prosperous and attractive nation amid an aging population and declining
birthrate. While some people refer to these stagnating years as the lost
years, I would rather characterize them as the "maturity period."
If we consider that human memories begin to remain after the age of five,
the generation with war memories is now 85 years or older. Those who were
drafted into the military are now over 99 years old, making them a rare
breed. Those enrolled in military training schools, such as the Army Cadet
School, the Army Academy, and the Naval Academy, were destined to join
the battle if once the allied forces invaded our mainland. Among these
people, I was a first-year student at the Tokyo Army Cadet School when
Japan accepted the defeat. I was 14 years old at the time and am now 94
years old. I am absolutely the youngest among those who once belonged to
military organizations including schools. Wartime experiences, as well
as memories, of people are rapidly fading.
The 80 years since the end of the war have been peaceful and free of war, but what about the 80 years before the end of the War? It dates back to 1865, the first year of the Keio era as shown the chart above. This was a time of internal battle leading up to the restoration of imperial rule. Three years later, the Meiji era began, and the great reforms of the Meiji Restoration began. The nation as a whole worked to enrich the country and strengthen its military in order to compete with the Western powers. After overcoming the internal Seinan War, Japan continued to win the Sino-Japanese War, the Russo-Japanese War, and World War I, before moving on to the Manchurian Incident, the Second Sino-Japanese War, and the Pacific War. The era of war came to an end in 1945, with over 3 million military and civilian casualties. Eighty years of fighting continued as our society was modernized from feudal to democratic.
Take a look at the chart above. The 80 years of peace since the ceasefire
shine like a miracle in history.
We cannot maintain peace if we forget the preciousness of peace. Humanity
cannot be said to have progressed unless we put aside wars that show no
regard for the dignity of the individuals. I have witnessed many advances
in human knowledge, from DNA and the Big Bang to AI, but we are still far
from the wisdom to put an end to war. I long for the day when war is eradicated.
