Window Opening Book Discovery Picture Book Plus Yokai (Japanese monsters/spirits) I've read it a few times, but I think you can still enjoy it. It's a window-opening type, so they enjoy the action of flipping and closing the windows, and they played with it alone with concentration for a while (lol). Because a child was reading it, there is one tear (see photo 4). Immediate purchase OK! ^_^ Yokai Picture book Book Yokai Ghost Picture book Pop-up book
