In approximately 1939, during a period of heightened tensions and escalating conflicts, a captivating photograph was taken in Tokyo, Japan. The image showcases a group of schoolgirls diligently wearing gas masks as they engaged in a drill specifically designed to prepare them for the potential threat of a poison gas attack. This exercise was conducted as a precautionary measure in response to the prevailing global climate of fear and uncertainty.

During the late 1930s, the world was on the brink of another devastating war, which would later become known as World War II. In Asia, specifically, Japan had already embarked on an aggressive military campaign, expanding its influence and territorial control through conquests in Manchuria (1931) and China (1937). As these military advancements continued, fears of potential warfare tactics involving the use of chemical weapons grew among the civilian population.

In response to the perceived threat of poison gas attacks, various countries, including Japan, implemented drills and safety measures to safeguard their citizens. In the case of the photograph taken by Masao Horino, it portrays young schoolgirls clad in gas masks, embodying the vulnerability of civilian populations amidst the looming possibility of chemical warfare.

The image serves as a poignant reminder of the stark realities faced by individuals, even the youngest members of society, during a tumultuous period of history. It symbolizes the efforts made to protect and prepare the populace, as well as the anxiety and apprehension that permeated everyday life in anticipation of potential conflict and its devastating consequences.
