I'm sorry, my Japanese is not good, so I will have to write in English: The red cheese, is actually just a little wheel of cheese covered in red wax. You are supposed to remove the red wax part, it should have a loose strip for you to peel it away. I am sorry that this was not clear. I think it is safe to eat though, and I know many children eat it by accident too because they haven't seen it before either - so it must be ok (health-wise). Also the cottage cheese is meant to taste sour, but I don't eat it - I think people often eat it with salad. 😊 Great video!
