It sure is hot in Japan. My kids had to sweat through weeks of heat before they were finally released for summer vacation in the third week of July. They go back to school next Monday, and I feel sorry for them. It's likely to be hot and humid for a few more weeks.
The classrooms at the elementary school my kids attend aren't air-conditioned. This is typical of public schools in Japan, although most private schools now have air conditioning. In my older son's classroom, on the top floor of the school, the temperature stays above 30 degrees for most of the summer. Sometimes it hits 36 degrees. I didn't get alarmed when I first heard those numbers because I'm American and can't think in Celsius. But when I did the math, I realized my babies are baking in classrooms that hit 97 degrees Fahrenheit.
I worry my kids aren't learning when school is so hot. And such high temperatures aren't healthy for children, who are more vulnerable to heat than adults are.
