I’m a diagnosed epileptic will this effect my chances? And is there any advice on how I can get my prescription and its legality in Japan?

As stated I am a tonic clonic epileptic, other than that I an quite healthy. Stereotypically I don't get seizures from photosensitive reasons, its more down to stress. And I normally have a seizure between 1-6 months. (It can fluxuate depending how stressed I am)
