Japan Pharmacies

Has anyone successfully ordered Ketotifen from a Japanese pharmacy? I live in Canada, it's not covered so it costs me $170/month, which is pretty expensive! I've seen a few posts on here that mention Japanese pharmacies selling it over the counter, but have seen few actual company names mentioned. My doctor is useless and keeps prescribing me 1 month at a time for some reason and it's becoming a hassle... I came across Bio-Japan. net, but is it legitimate?

Any leads would be greatly appreciated!
