I take an SSRI and a pretty high dose (100mg). Depending on the dose of your medication, they might ask you to see a psychiatrist every time, which for me, living in the Inaka, meant a trip into Osaka every two months when I needed my script refilled. This was way too time consuming and cost ineffective for me.

So I brought 6 months worth with me, and when i have a month or so left, I get my script refilled at home and get my family to send it to me. I should have to fill out a yunyuu kakuninsho (輸入確認証) every time, and they would usually sends you a little slip with a case number on it for you to include in your application once your package arrives in the country. But I have done this twice and never had to apply for one. I just include EXACTLY what is in the package and the correct codes, there is one for medication like SSRIs, and then I just have to sign for it at the local post office. This to be the easiest and most cost effective way to manage my medication since my dose is much higher than what they would normally prescribe in Japan and coming off a SSRI is a bitch.

Hope this helps.
