How to Handle Emergency Situations (Burns, Severe Pain) and other health issues in Japan?

Hi everyone,

I'm currently living in Japan and have social insurance. I want to be prepared for any emergency situations, such as severe burns on the hand or other places, or experiencing severe pain. Could someone guide me on what steps to take in such emergencies?

Here are a few specific questions I have:

1. What should I do first in case of an emergency like a severe burn or severe pain?
2. Should I go directly to the hospital, or is there an emergency number I should call first?
3. Do I need to bring any specific documents when I go to the hospital in an emergency?
4. How does the process work with social insurance in emergency situations? Are there any immediate costs I need to be aware of?
5. Are there any emergency services or hospitals in Osaka, Suminoe Ward, that you would recommend?

Thank you for your help!
