There are 3 major cell-phone companies in Japan. NTT Docomo, AU, and Softbank. NTT Docomo coveres the largest area. But the cost is high. When you make a contract of mobile phone after you come to Japan, if you buy mobile phone through these cell-phone companies, it may be cheaper than usual. If you bring your mobile phone, it is cheaper to make only a contract of SIM card.
How to buy mobile phone
The necessary documents are as follows.
２、National Health Insurance card

When our school has new student orientation, cell-phone company’s staffs who speak English, Chinese, and Vietnamese etc. will come to school to explain about goods and sale. If your Japanese level is not so high, you can buy it with an easy mind.
