Canned Bread in Disaster

The following message arrived from our apartment management office.  We arrived too late to grab free goods but even if we had, we don't own a can-opener!

Our lodge office provides an emergency kit and three days' worth of preserved foodstuffs for residents.  They are distributed to residents for free:
1.Canned Fruit
2.Canned Bread
3.Canned Tuna

What is canned bread??  I looked on the web and found the following advertisement.  

"Are you prepared for an unexpected natural disaster?  When the electricity, water and gas all stop...? We would face many problems in such a disaster, and food is one of them. Akimoto-Pan's Canned Bread is just as soft and delicious as fresh bread, can be stored long-term, and easily opened when needed!  This yummy bread is made using a special process allowing it to be stored long-term. There are three to choose from; orange, raisin, and strawberry. You can have your favorite flavored fresh baked bread anywhere, anytime, you want!"

The Japanese plan well for disaster.  They live one of the most seismically-active parts of the globe!
