new in Tokyo!

Hi all,
I am here since almost a week. My interests are Acupuncture but mostly Moxibustion.

I have two problems, one is that I am vegetarian and cannot find Japanese vegetarian restaurant and the other is I don't get wifi for cell phone for a decent price. I am here as a tourist and plan to stay two months.

Would be nice to get some advice from the Tokyo pros :)
Have a wonderful Sunday all,
Sibylle
