In some cultures, you must not wrap your gift, so that everyone can see what you’re giving. In other places you don’t unwrap a present when the person who gave it to you is there. What if you don’t like it?
In Japan people put a lot of time and effort into wrapping gifts. The more layers the better. The exhibition includes a huge, highly instagrammable installation of furoshiki (Japanese gift wrapping cloths) which you can step inside, making you the gift!
