The Hidden Smoke Alarms of Japan

When we bought our home in Japan in 2006, it didn't come with any smoke alarms. Concerned about fire safety, we installed a smoke alarm ourselves, not because we knew of any legal requirement, but simply because it seemed like a sensible precaution.

That is why I was recently shocked to learn that smoke alarms have actually been mandatory in Japanese homes for many years. Despite living in Japan for nearly two decades, I couldn't immediately think of a single friend or acquaintance who had ever mentioned having one. In fact, I have asked friends and acquaintances, and they say they don't have any. So, I assumed that smoke alarms were far less common here than in my native Ireland.

It turns out that homes built from 2006 onwards were required to have residential fire alarms installed. Often, these are small, unobtrusive devices mounted on ceilings or walls, making them easy to overlook. Some people may not even realize they have them. Whether they are hidden in plain sight or simply not something people talk about, they seem to attract far less attention than I would expect.
