I will be moving to Japan in a few months and I am wondering about what kind
of telephone plans there are.  I'm wondering if I should get a cell phone or
a land line?  What kind of coverage do cell phones get?  What kind of plans
are there?  Here in the US, audio quality is often poor, coverage is spotty,
and most companies require minimum service agreements.  I also know that
cellphones have many options, they can take pictures, connect to the
internet, etc.  What are the best phones, best coverage, best quality,
etc...?
