The picture shows a big group of young people having a barbeque in a park. I think they are from Japan.
There are about 20 people in the group, and most of them are wearing jeans and blue or dark-coloured shirts. They are having a lot of fun, and some of them are making faces at the camera. Everybody is trying to get in the picture.
They are in some kind of a park or a forest. They could be on holiday, or it could be a school trip. I don't know what they are cooking. It could be hamburger, but it could also be some special Japanese food!
