Dementia: Japanese students are learning how to help people living with it

After school in western Tokyo, 10 students of different ages sit quietly in a classroom at Haijima High School. They have come voluntarily to learn about dementia from Naomi Saeki, an older woman who teaches the subject as a volunteer.

Saeki writes several key figures on the board, then raises a colorful brochure. “Since 2025, care and dementia have been a huge problem. Why?” she asks. She explains that most baby boomers turned 75 that year, and that the statistical risk of developing dementia rises at that age. Around 15 percent of Japan’s population is now 75 or older, she says.

Since 2025, care and dementia have been a huge problem. Why?

The lesson focuses on situations families may already recognize. “Some of you may have a grandfather with dementia. Maybe he only takes out rubbish that isn’t rubbish? Or perhaps he makes unwise financial decisions!” Saeki tells the students. “I want to inform you today so that you can support them better.” The students respond with quick nods.

The class reflects a broader challenge for Japan. Growing numbers of people with dementia are pushing the social systems of aging societies to their limits and weighing on national economies. The article looks at the social and economic approaches Japan is using to manage what it presents as a growing crisis, and considers what the country might learn from Germany.
