Ramen Bowl w/ Lid? (like in Ponyo)?

There is a bowl that exists, that has a lid, that you put ramen in and broth and cook the ramen (like in the animated movie Ponyo), and I would like to shop for one for my sister, but I have no idea what they are called. Does anyone know the style bowl I am talking about? Googling "ramen bowl with lid" isn't getting me much, hehe.
