The Nagoya City Board of Education has ordered elementary, junior high, and high schools to cancel club activities in environments without air conditioning [1].

This directive comes as a response to dangerous temperatures in Japan's Tokai region, where heatstroke risk has reached critical levels. The decision highlights the increasing vulnerability of students to extreme heat during summer months and the necessity of climate-controlled spaces for safety.

Temperatures in the region have climbed rapidly, with Nagoya recording a high of 37.8 degrees Celsius [1]. Gifu recorded a high of 36.7 degrees Celsius [1]. These figures are part of a broader heatwave where some forecasts predicted highs reaching 39 degrees Celsius in Nagoya and 38 degrees Celsius in Gifu [4, 5]. Some reports suggest temperatures in the area could approach 40 degrees Celsius [3].

Heatstroke alert warnings were issued for Aichi, Gifu, and Mie prefectures [6]. The board's notification to schools was issued to cover a period from yesterday through tomorrow to prevent heat-related illnesses among students [2].

Local residents have noted the severity of the weather compared to other urban centers. "It is hot. It is crazy. Tokyo is hot, but Nagoya was hotter," a resident said [7].

The move by the education board follows a pattern of increasing heatstroke warnings across Japan. By restricting activities to air-conditioned environments, officials aim to mitigate the risk of heat exhaustion and heatstroke during the peak of the afternoon heat.

The suspension of school activities in Nagoya reflects a growing systemic shift in Japan's approach to public health during extreme weather. As temperatures frequently approach 40 degrees Celsius, the reliance on air conditioning is moving from a luxury to a safety requirement for educational infrastructure. This trend likely signals a future where traditional outdoor school schedules are permanently modified to accommodate a warming climate.
