Research achievements


■ Background of the development of the long-term care medical field art "Mikkel Art" 

As the company name suggests, for several years after starting the business, we were engaged in the landscape formation business in the area by working on mural paintings centered on "spray art".


The turning point was in 2010 when I got the job of drawing spray art on the outer wall of a pay nursing home. Looking at the users of the facility while drawing the mural, I felt that there were few opportunities for communication because I only had to go back and forth between my room and the dining room. When asking the user, "What kind of picture do you want to see?", Many answer the scenery of their hometown, and the elderly people value their hometown and old memories. I found out. Conversations were lively, such as places of memories, play as a child, and stories of first love, and sometimes I talked with users for more than two hours. Looking at such users, I thought, "Let's make art that will trigger conversations that make you want to talk to someone!" Is the origin of Mickel art development. However, although I was able to draw pictures, I had no knowledge of the medical / nursing field. We steadily interviewed the issues at the nursing care site and what the elderly are looking for, and asked for their cooperation with specialized institutions. The effects of Mickel Art, which was shown through joint research with Tokyo Medical and Dental University, are highly evaluated for their contribution to dementia care. I received the Urakami Award.

"Mikkel" in Mickel Art means "find". This is because the person who sees the picture "finds memories" and "finds what he wants to do" while talking. For that reason, Mickel Art has been devised in many ways to make people look like a picture-like puzzle.


In the future, Mikkelart will continue research toward further evidence building that it is effective in preventing dementia and improving higher brain dysfunction.


■ Purpose and significance of Mikkel Art

To solve problems such as an aging society, a shortage of human resources in the nursing care field, isolation of the elderly in the community, and lack of communication through art.

Support message

I sympathize with Spray Art Exin Co., Ltd.'s corporate philosophy of "working on social issues through art."

We hope that the company's Mickel Art will expand "communication that can only be achieved by art" in medical / nursing care and childcare settings, and create an environment where various people can spend time comfortably.
