ヒロシマの被爆体験講話　梶矢　文昭（かじや　ふみあき）証言者

Overview

A survivor’s lecture-testimony from Hiroshima recounts how World War II unfolded for the speaker’s generation, then focuses on the immediate circumstances and long-term meaning of the atomic bombing of Hiroshima on August 6. He frames the bombing as a turning point in warfare: after years of fighting that seemed, at the time, as if it might end quickly, the war escalated into a fundamentally different scale of destruction through atomic weapons.

World War II Background and Escalation

• The speaker explains the timeline relative to his childhood:
  • The war began with Germany’s invasion of Poland (1939).
  • Japan entered WWII after attacking Pearl Harbor (1941).
  • Japan’s defeat came when he was about six years old.
• He emphasizes a general lesson: wars rarely end quickly once started—in Japan’s case, the conflict continued until the creation and use of the atomic bomb.

Targeting Details and the “Decision Paths” of the Mission

• He describes the planned bombing in terms of historical targeting:
  • Hiroshima was the first target.
  • For the second bomb, Kokura was intended, but weather prevented confirming the target, so the aircraft proceeded to Nagasaki.
• He also references a third target concept:
  • Niigata was considered, but it was not used because Japan surrendered after Hiroshima and Nagasaki.

Hiroshima’s Destruction and the Explosion Mechanics

• Using today’s Peace Park as a reference, he explains:
  • The intended drop point near what is described as the “Aoi Bridge (Blue Bridge)”.
  • The actual outcome: the bomb landed about 200 meters off target, and it detonated in the air rather than on the ground.
• He describes key effects:
  • Blast radius: approximately 2 km.
  • His location: about 1.8 km away, at a temporary classroom near Hiroshima Station.
• He emphasizes that:
  • The atomic bomb destroyed the city within that radius as a single event.
  • People nearby suffered quickly and massively.

Eyewitness Accounts: Evacuation, Student Deaths, and Personal Loss

• He recalls being a first-year junior/high school student and describes evacuation “dispersal meetings,” where students were separated from the city center.
• He states that of around 8,000 junior high students involved in work related to creating firebreaks/empty spaces (by demolishing houses to reduce fire spread), thousands—especially girls and boys—died at the moment of the bombing.
• He narrates intense sensory trauma:
  • The flash followed by a boom (“Pika-don”).
  • Collapsing houses.
  • Shattering glass as a lethal hazard—glass fragments embedded in family members caused severe injury and lasting harm.
• Family tragedy:
  • His sister was described as being killed instantly when a pillar fell on her.
  • He later reflects on the unsettling detail that she had a slight smile in death.
  • His mother survived severe injuries, including many glass shards embedded in her body, and lived to an old age.

Escape Attempts and the Dead in Rivers

• He recalls crawling out of rubble and witnessing long lines of people fleeing.
• He describes rivers near the Peace Park being filled with bodies after the blast.
• He stresses confusion:
  • People didn’t truly understand what an atomic bomb was.
  • Some only later realized the true nature of the disaster.
• He references an illustrated story based on his testimony (by a high school student), depicting survivors attempting to escape—fleeing into burning areas and toward rivers.

Memory, Testimony, and Reconciliation Through Narration

• He includes references to writers and later works connected to the bombing aftermath, showing how the horrors were recorded and communicated.
• He describes receiving small relief food and how rescue efforts provided brief moments of survival support.
• He recounts a family tragedy shaped by evacuation policy:
  • His sister chased after a bus to return to their mother.
  • The decision ultimately led to her death in the bombing—reinforcing the theme of desperate desire to remain with family.

Nuclear Weapons Warning and Modern Relevance

• He ends with a direct anti-nuclear message:
  • The Hiroshima bomb’s scale is contrasted with modern nuclear arsenals, arguing present weapons are vastly more powerful.
  • He warns that the entire region could be devastated.
  • He urges containment and action to prevent nuclear use.
• He calls on global responsibility to stop nuclear weapons from being used and concludes with hope that collective awareness and action can prevent catastrophe.
