Cellphones in Japan
Having a cellphone during your time in Japan can make the difference between enjoying your free time a bit, and enjoying it a lot. It's the one tool that massively simplifies making friends, so we absolutely recommend either bringing your own (if you can confirm that it works in Japan) or renting one here. For stays of one or two weeks, GenkiJACS rents prepaid cellphones. However, for any longer stay, we recommend you to rent one through AIRS, a rental cellphone provider. They offer cheaper rates, and credit card payment.
If you plan to bring your own phone, confirm with your cell phone company that your phone supports Japanese 3G networks. Also confirm the roaming charges, so you aren't hit with a big bill at the end of your stay!
If you won't bring your own phone, use the chart below to decie which rental option is best for you.
