Mobile phones are essential in daily life. As a tool for communicating with friends or coworkers, looking up something, translating, and contacting in an emergency, a mobile phone has many important roles in our lives. We can’t think about life without a mobile phone anymore.

When you have a mobile phone in Japan, it’s important to choose the best mobile carrier for you. Many mobile phone carriers have many plans, from the largest carriers to cheaper SIM carriers.

Though new cheaper SIM carriers are increasing these days, I would love to introduce the 4 largest Japanese mobile phone carriers in this article.
