We start in Tokyo, where one small cafe has become famous for far more than its cakes and coffee.

At Orange Day Cafe, muddled orders, long pauses and gentle confusion aren't mistakes, they're the point.

The monthly pop-up was created to give people living with dementia a place to volunteer, and one of its best-known helpers is Toshio Morita, an octogenarian living with dementia who's become something of a local celebrity.

Our correspondent Shaima Khalil went to meet him and to see how a simple cup of coffee can turn into an act of community.

Once a month, this small cafe in Sengawa, western Tokyo, turns into something different.

There's still delicious cakes, coffee and tea, of course, but the mood and the purpose of this place change.

87-year-old Morita-san has been living with dementia for years.

He's one of the volunteers at the Orange Day Cafe, or the Cafe of Mistaken Orders, as it's now famously known.

Morita-san welcomes customers wearing an orange apron, a black and white headband, and a charming smile.

This monthly pop-up gives people with dementia a chance to volunteer and connect with the community for a few hours.

You can see just how much Morita-san enjoys it.

Mix-ups can happen, of course, but it's all part of the experience and all taken in good humor.

Morita-san is supported by another younger volunteer.

The menus and tables have been color-coded to make it easier for the elderly waiters to take the orders.

We have six tables here, so we put the six colors of the flowers on each table.

Aki Kokanna is the founder of the pop-up cafe.
