In Japan the most cell phones are sim locked and Japanese don't usually change between SIM cards. That's why you can't find SIM cards in the stores in Japan and when you ask a Japanese they don't know; even though they are simple to find in other countries. In the end, you often hear the complaints of foreign visitors who can only connect to the internet in their hotel room and use public phones that are not so easy to find.
But even in Japan there are services for foreign visitors to rent SIM cards, smart phones and portable wifi devices and these will be introduced in this article.

■b-mobile VISITOR SIM 14Days Prepaid■

With this SIM card you can use the internet as much as you want during 14 days. The internet speed however, is rather slow at 300kbps. It takes 10 seconds to open the yahoo homepage from a smart phone and even longer from a PC. You should consider this service as helpful for viewing emails. It isn't exactly clear which devices you can use with this service, but it is safe to assume that only iPhones and iPads work with this service.
