As she said, "I was able to capture a natural, unguarded expression that I don't usually show," this shot perfectly reflects her sparkling, radiant smile while also showcasing a refreshing, open expression as she enjoys an extraordinary experience in Europe. ■ Profile Sayo Kanagawa (born October 31, 2001). 24 years old.
