61-year-old Masahiko Sato, who has become a kind of "poster boy" for Japan's growing number of people with dementia, strolls during a cherry blossom viewing event at Omiya park in Omiya, north of Tokyo, Japan, March 27, 2016. Encouraging people with dementia to speak out is part of Japan's effort to ease the negative image of a disorder that affects nearly 5 million citizens and is forecast to affect 7 million, or one in five Japanese age 65 or over, by 2025.
