It's been a while, but I updated the first page
with the current viewing info. Currently, FMA:Brotherhood is re-airing in Japan on TokyoMX.
I'd like to update the info for official viewing options for other countries as well.
If you're living in outside of U.S. or Japan, and has official/licensed viewing options to watch FMA:Brotherhood episodes currently available, please post here and share! ETA
: For a limited time, Gyao in Japan will re-run full 64 episodes of FMA:Brotherhood through Aug. 8.(Source: Ad in GanGan July issue that will come out in June 11)
