Topical finasteride Availability

I've looked up a little bit about the availability of these 2 treatments for AGA in Japan and I found out that Minoxidil is available as "Rogaine" and can be purchased without prescription, while topical finasteride is not "approved" or widely distributed. I was wondering if there was any chance of being able to bring from Europe to Japan a 18mL bottle of topical finasteride and, once arrived, find a dermathologist or a clinic who could prepare the equivalent to use there. I'm worried about the fact that it might not be legal or that you can have problems even if it's for personal use and only a bottle. The treatment with topical min and fin, just to make it clear, is already ongoing in my country (where both are widely available in topical solutions), and at the moment I'll go to Japan it will be 1.5 years from the beginning of the treatment.
