Nearly 5 million people in Japan live with dementia and thousands are going missing from their homes and carers every month.
In Japan’s second biggest city, Osaka, Atsuko Hajihata is frantically looking for her missing grandfather Akinori Matsuyama.
For the last several months she has been handing out leaflets on street corners and train stations, asking people to contact her if they see her grandfather.
He walked out of the family home in January and has not been seen since. Ms Hajihata says she is nervous because she thinks he has dementia.
“I still have hope of finding him but I’ve heard that bodies of drowned people have been found,” she said.
“But maybe he’s being looked after by people.”
Some of the missing turn up in mental institutions or aged care homes.
