[sumo] [non-sumo] cell phone rental in Japan

[Danji]

Howdy Sumoans,

Sorry for this non-sumo-related post during the lull between honbasho, but I
would like to rent a cell phone for my one-week stay in Japan next month and
I'm wondering if any of the list members out there have any recommendations.
I have only lived in Japan as a resident and have never had to rent a phone,
so this is new territory for me. I remember Rannohana telling us about his
rented cell phone over chanko in Osaka a couple of years back, but I forget
the company. Anybody have any suggestions?

And yes, my visit just happens to coincide with the Haru Basho. It would be
cool to hook up with any other ML members who might also be attending, but
I'll save that for a separate post.

Many thanks in advance!

Dan (Danjinoumi in a past life)
