How to Save Money on Electricity Bill in Japan

How to Save Money on Electricity Bill in Japan Money

A few years ago, electricity retailing was liberalized in Japan. In this article, I will write about how to save money by changing power companies. Up until now, consumers have not been able to freely choose the power company they contract with. As a result, there were limited ways to save on electricity bills at home. Now you can choose the power company that suits you. I was able to lower my electric bill by changing my power company.
