Not sure if this has already been posted, but I found a video on youtube of Hare Hare Yukai in 1080p

the embedded video might not be 1080p, and I'm not sure if you can change it from there, so click on the link if you want to make sure.
never mind, you can change it, just click play and the option to change quality is shown in the bottom left
