Ginmaku Cafe has been showing classic films to their elderly patrons as a way to prevent dementia. Movies dating back to the 1940’s and earlier were edited to 20-minute long clips and shown on their 80-inch screen. This is a form of reminiscence therapy, which aims to maintain brain activity and memory retention. The old films, which are full of information and images from the past, induce nostalgic memories that keep the brain cells from dying and the brain from shutting down. This is said to counter dementia, a mental illness that usually afflicts the elderly and severely damages the intellect, memory, and other brain functions.

The Okinawa-based video production company Net TV Kaisou established the cafe in February 2018. There are plans to build cafes of the similar concept in other parts of the country. Moreover, the company aims to broaden the reach of its research by distributing copies of the edited films to hundreds of nursing homes in Japan. The company has also expressed the possibility of renting out the curtailed versions of the classics to customers.
