Most Japanese homes and companies keep stocks of emergency food to ensure survival if a disaster strikes. These range from bread, canned to preserve its freshly baked softness, to retort pouch meals that can also be eaten cold. Freeze-dried foods are also popular, since all you need to do to prepare a meal is add water. Today, the availability of delicious emergency foods helps people avoid waste by rotating emergency stocks to form part of their daily meals. These new technologies mean that even in a disaster, you can have meals that are safe to eat and taste great.
