Beyond the boumdary

I went to Kohata station to get a reserved seat to go to Kagoshima/Hakata tomorrow. The train I wanted was full. So was the next one. And the next one. So I'm now going at the break of dawn and will be there two hours early...

I'd noticed this place outside the station cefore, but assumed it was a small animation school or something. Turns out it's a bona fide studio, and I've actually seen some of their current series, Kyokai no kanata/Beyond the boundary, and quite enjoyed it.
