🌏 What It Means for Foreign Residents
Japanese summers are humid, and heat builds up in the body even on days when the temperature does not look extreme. If you apply the sense of "hot" you learned back home, your precautions will often fall short. The biggest practical gap is what happens if someone collapses. You call an ambulance by dialing 119, and many foreign residents worry about explaining the situation in Japanese. Some fire headquarters provide three-way calls with an interpreter or other language support, so the priority is to stay calm, say "kyukyu" (救急, ambulance), and give your address plus a landmark. For the earlier stage — when you are unsure whether to call an ambulance at all — some areas offer #7119, an emergency advice line. Check before the heat arrives which numbers work in your municipality. At work, many foreign workers are in exactly the high-risk settings: outdoor sites, hot kitchens, warehouses. Risk rises further when your position makes it hard to ask for a break or water. Saying something the moment you feel off is the single most effective form of self-protection.
💡 Key Points to Know
1Dial 119 for an ambulance. Start with "kyukyu desu" (it's an emergency), then give your address, a nearby landmark, and the symptoms in short phrases — you do not need long sentences
2If saying your address in Japanese worries you, keep your residence card, a note with your home address, or a map on your phone ready to read from
3When you are unsure whether to call an ambulance, some areas let you consult #7119 (emergency advice line). Check your municipality's official site in advance for which numbers apply
4If heatstroke is suspected: move to a cool place, loosen clothing, cool the neck, armpits and groin, and if the person is conscious, give water and salt
5If the person cannot drink on their own, responds strangely when spoken to, or cannot walk straight, consider calling 119 rather than waiting to see
6FDMA heatstroke transport data is published continuously from April through September. Remember the difference: preliminary figures are provisional, monthly finalized figures are the official ones
7If your job involves outdoor work or hot environments, confirm with your employer how breaks, hydration and working hours are handled
