Hi All:

I am a gaijin who is about to move to Japan, and I have a few
questions that I was hoping someone who has made the move could
answer:

Is there a residential broadband internet service that has English
technical support in Japan?  (I speak no Japanese).  I would be
looking for the fastest speeds possible, as I am used to cable modem
service in the U.S.  If possible, I would also be interested in IP
phone services, if they are available.  My research indicates that
Japan has a lot of ADSL options, but I was wondering what someone who
actually lives there has to say about them.

Also, I am very interested in studying martial arts, and could not
imagine spending time in Japan without studying some.  Could you
please give me some tips as to how to locate a dojo/teacher, and any
important information about training in Japan?  (Tokyo area-- Akasaka
or so).

Also, I will need to find a cell phone in Japan.  I am leaning towards
getting a NTT/DoCoMo phone, as they seem to be the most widespread and
most accessible, but I would like to hear about your experiences with
whichever phone you use, as I would like to get the best and easiest
to use.  I will probably want web-access and e-mail on the phone as
well.

If you have any other tips about locating housing, renting an
apartment, dealing with the government, or otherwise setting up a home
in Japan, I would be most appreciative if you could post them. 
Thanks, I look forward to hearing from everybody.
