This article provides informations about mobile battery available in Japan and aims at contributing positively to the preparation of your upcoming trip.

Imagine you are walking for hours in the beautiful city of Kamakura for visiting the magnificent Buddha, or that you are playing Pokemon Go in the streets of Shibuya. You are having fun, you are enjoying your Tokyo life, but the worse happens : your mobile phone’s battery level falls to 5%. Then you realize : how am I going to take pictures, videos, listening to music, opening the map for going back to my hotel ? This situation is just horrible.

While reading this you may think that it will not happen to you, but it actually could. In order to avoid this situation occurring, let’s prepare a plan B : a mobile battery.

A mobile battery is an external battery that ones can charge and use for charging any electronic device. It is not much used abroad, but in Japan, be sure almost everybody have one in his or her bag.

In Japan, smartphone is used in lots of cases. In addition of using it for Internet, checking the map, sending messages and posting pictures on SNS, we actually use it also to pay at the supermarket, to take the train, to check our bank account and so on.

The disadvantage of this multi-purpose usage is that battery consumption becomes terrifically fast. Personally, I need to charge my phone at least twice to three times a day. In that case, a mobile battery can literally save a life.
