Emergency Services Day (Kyuukyuu no Hi)

What Is Emergency Services Day?

Every September 9th is "Emergency Services Day" (Kyuukyuu no Hi). It was established in 1982 by the Ministry of Health and Welfare (now the Ministry of Health, Labour and Welfare) and the Fire and Disaster Management Agency, based on a wordplay reading: 9 ("kyuu") and 9 ("kyuu") together sound like "kyuukyuu," the Japanese word for "emergency." The aim is to deepen public understanding of emergency services and emergency medical care, and to encourage everyone to learn basic first-aid skills. It's an important day for turning awareness about protecting your own life and the lives of loved ones into concrete action.

The Historical Evolution of Emergency Medicine

Emergency care has dramatically advanced through systems built on scientific evidence.

• The birth of paramedics: In Japan, the Emergency Life-Saving Technicians Act took effect in 1991, allowing trained personnel to provide advanced first aid on the scene. This marked a major paradigm shift, turning "time spent traveling to the hospital" into "time used to actively save lives."
• The importance of bystanders: Analysis of historical survival data has proven that first aid given by bystanders—people who happen to be present—has a decisive impact on survival rates and long-term recovery. This fact has driven the nationwide spread of AEDs and first-aid training courses.

The Science Behind How First Aid Saves the Brain and Life

The first few minutes of treatment after cardiac arrest hold the key to protecting brain function and keeping someone alive.

• The brain's tolerance for lack of oxygen, and chest compressions: When oxygen supply stops, the brain begins to suffer irreversible damage within minutes. Chest compressions performed at the scientifically correct pace (100-120 per minute) act as a physical pump, continuing to send blood to the brain in place of the heart and minimizing damage.
• The logical algorithm inside an AED: An AED (Automated External Defibrillator) uses a built-in computer to instantly analyze the heart's rhythm and determine whether an electric shock is needed. Thanks to this "scientific eye," even people without medical training can safely and confidently take part in saving a life.

Fascinating Facts About Emergency Services

• The spirit of "Good Samaritan" protections: The principle that someone who provides first aid in good faith shouldn't be held legally responsible if the outcome is unfortunate. Even today, this remains an important legal and psychological foundation that supports people's willingness to act courageously.
• "Smart emergency response" in 2026: AI now analyzes the content of emergency calls in real time, instantly matching the most appropriate dispatch route and checking which hospitals are ready to receive patients. A data-driven life-saving system is helping to close the "gap" where every second counts.
• The history behind "119": Japan's emergency number was originally "112," but to prevent misdialing on rotary phones, it was changed to "119"—placing the "9," which requires the longest dial pull, at the end. A simple but clever piece of human-centered design.
• The case for appropriate ambulance use: A rise in calls for minor issues risks delaying response to patients who truly need urgent care. Using the telephone consultation hotline "#7119" is a smart way to help allocate limited resources where they're needed most.
• Psychological First Aid (PFA): Care isn't just for physical injuries—it also matters for the mind after a shock. At the scene of a disaster or accident, simply "staying close and offering reassurance" is recognized as a scientifically supported way to help reduce the later risk of PTSD.

Tips for Spending Emergency Services Day

• To mark "September 9th, Emergency Services Day," check where the nearest AED is located in your neighborhood. Having this information mapped out in your mind helps prevent panic in an emergency and is one of the most effective ways to train your brain's executive function.
• Watch a video on basic first-aid procedures to refresh your memory. Taking in visual information and mentally rehearsing the steps helps activate your motor system and prepares you to respond instinctively when it matters.
• Check the contents of your first-aid kit and replace any expired medicine or worn-out bandages. Keeping your supplies up to date is a logical step toward strengthening your own readiness for a crisis.
• Turn your own health information into data. Register allergies, existing conditions, and emergency contacts in your phone's medical ID. Accurate information for first responders can serve as a lifeline for you.
