“3 days of emergency food is enough.”
Many people think this way, but depending on the situation, you may need more.
According to Japanese government guidelines, 3 days is the minimum standard.
This period is based on the time when rescue operations are prioritized.
To maintain your daily life, preparing more than that is important.
* First, check what kind of food you have prepared

■ Day 1: Adjust to sudden changes
Power outages and water cuts can drastically change your daily life.
Limited light and information can increase anxiety.

Hygiene conditions directly affect comfort and health.
■ Day 3: Information and stability matter
When your phone battery runs low, communication and information access become limited.
Being informed affects your sense of safety.
