Help with TV program
 

I am a photographer from Scotland, I will be taking photographs of the Japanese footballer Koki Mizuno, I like to research people who I photograph it helps me understand them and get better pictures. I have found a clip on youtube of Koki Mizuno appearing on a Japanese TV program. Would it be possible for someone to tell me what this program is about and why is he peeling an apple? I have posted a link bellow for the youtube clip. In return If I can help with your English questions or anything to do with Scotland I will do so.
Thanks for your help.
