Japanese Flipbook has a Surprise at the End (video)

From the you can't do this with ebooks dept ...

Flipbooks have been around for so long that they are arguably the oldest type of animation, but you rarely see them these days outside of kid's books and the occasional art project.

That's why when I came across the following video of a flipbook, I thought everyone would get a kick out of it. The video is short, so watch it all the way through to see the surprise.

The video showed up in the Twitter feed of Dear Author  a couple days ago, but other than the fact it was made in Japan and that there are a bunch of similar videos uploaded from that account, I can't tell you anything about it.

Does anyone have info on the flipbook's creator?

Update: Ask and you shall receive.  Igorsk did some sluething and found the publisher's website and its Youtube channel. Thanks, igorsk!
