Recently made a trip to Kyoto so I could not miss a chance to pay KyoAni headquarter a visit. I have no idea what size an animation studio in Japan is in general, but my first thought when I saw the yellow building was "it really is small." Basically the same size as the houses nearly. Pretty easy to get to though, so I think it's worth the time.
When I was there, their car (in the picture) was out to get something and the person on the right came out to bring the package in. He offered to take a picture for me. I don't think I was lucky enough to meet one of the important staff, but he looked like a senior one so I should have asked for his name or picture nonetheless, just in case.
And finally (part of) the goods I bought from KyoAni shop.
