Will I be able to find a doctor/psychiatrist who prescribes Clonazepam in Tokyo?

Hi there!

I'm an American planning a to move to Tokyo, and am faced with a logistical problem.

I’m current taking 1mg of Clonezepam a day for for anxiety. Clonazepam – like Xanxan/Alprasolam – is a "benzo" that's a controlled substance in America, and is allowed in Japan (where it's classified as a "Psychotropic").

I’ve been on Clonazepam for over 10 years and am able to provide documentation of this (in the form of filled prescriptions).

My questions:

1. Which types of doctors in Japan can prescribe Psychotropic drugs? Is it only psychiatrists, or can general practitioners do so as well?
2. How likely is it hat I'll be able to find an English-speaking doctor willing to prescribe it to me? I'm not sure how commonly prescribed this medication – or other benzodiazepines – is in Japan…
