My friend Jason and I checked out the boat show in Tokyo. I leared a lot including that a big issue is if you are going to be out on the ocean for extended periods, like if you have a sailboat for example, storing and keeping food is a problem and people complain that the food that you can keep gets boring. Which brings up one company's solution...

It's bread in a can. (Bread in Japanese is called Pan. Pronouced "pawn").

According the company the bread stays good for a year. They were handing out samples and it tasted great! 😊
