The Concept "Playful"
Children possess programs to fully use the capabilities of the mind and body. CRN's starting point is the concept that playfulness starts these programs in operation. When children are absorbed in play, filled with excitement and a joie de vivre, the programs of the mind and body work at full capacity. We also define the "playful spirit" as a certain feeling or emotion, the thoughts, curiosity and inquiring mind that arise when an individual is absorbed in something. The definition of "playful spirit" also includes sympathy for others, positive attitudes, and a concern for people and things. In other words, a playful spirit encourages children's spontaneous learning.

CRN started playful research in 1999. In November 1999, CRN held a workshop called "Playshop 1999 - Let's Experience the Playful Spirit!" CRN held Playshops in July 2000 and March 2001 to continue its research activities.

In April 2001, Nagayama Chi-kichi was established as a new laboratory for learning and play. There we hold Playshops and make an open space available to younger children in elementary schools to come and play while we carry out our ongoing research.
