As we saw from their hilarious textbook doodles not too long ago, Japanese school children seem to be bursting at the seams with creativity. Now, with the slightly more public and temporary space of a classroom blackboard, some students with encouraging teachers were able to create some very impressive murals.

The bulk of these works were tweeted by one Kami-chan and seemed to have been made by a group of three students called “Kaiteru” over the previous school year.

According to comments written online, these guys take about an hour or two to make the murals, but mistakes can sometimes set them back to about three and a half hours. They also insist that they get all their studying done.

Or course these blackboard murals aren’t all done by these guys. Others seemed to have picked up where Kami-chan and friends left off.
