Medical School in UK to Japan

Hi

I am a 2nd Year Medical Student in the UK . My ambition is to live and work in Japan as a Doctor . I understand the first step to being able to do this is to pass JLPT N1 and sit the Japanese Medical Licensing Exam. Is this exam available in English or would I have to sit it in Japanese? One of my parents is a citizen of Japan although I am a UK Citizen only. After this , what is the process for specialty training in Japan?

Alternatively , I could go to Japan after my Medical degree ( 5 years ) as Dr.... and seek work in the pharmaceutical/healthcare finance sector. Is this a feasible option with N1 Japanese?

Although not impossible, I would put this up with astronaut in terms of difficulty.

N1 Japanese would be a starting point. Your Japanese would need to be at medical level. Non-trivial.

Of course, you need to pass the licencing exam. Of course, in Japanese. How can you be a physician in Japan if you don't have sufficient Japanese ability to pass the exam?

Other work may be easier and more likely to succeed.
