Survival kit

In Japan where many natural disasters have happened, we have lots of products which are very useful in case of emergency.

Some purchase a backpack which has a light, emergency blanket and long-lasting food and water for a few days. Others prepare a bag with own choices of emergency goods.

Some products are very convenient and uprising in a way. For example, there is a battery which generates electricity when any liquid is inserted. Those are so useful when there is no electricity that we take for granted in everyday life.
