I am pretty sure I already know the answer ("Get stuffed"), but I guess I'll ask.
Apart from renting a 3G type access point (or USB data stick), are there any prepay options for getting a SIM _INCLUDING DATA_ when visiting Japan? It would seem that unless you're a Japanese resident then you have a REALLY hard time getting prepay mobile services over there.
I am going for a couple of weeks in July and would prefer not to rent a phone, or rent a 3G access point. I would ideally like to buy a prepay SIM but the vast majority of the options are voice and text only (ie. they actively exclude data).
There is one place ( http://www.bmobile.ne.jp/lineup.html ) I have found that apparently does prepay sims but you need to order them in advance and I couldn't negotiate their site easily.
All the people I have spoken to have essentially said this is impossible but I'm hoping maybe someone has visited there recently and has better news.
