No matter when, where, or under what circumstances, nothing can change or replace the smile of a child. The smiling faces of these adorable children are burned on canvas. Wooden panel, acrylic paint, pastel. The "Akkun" series is a symbol of ever-changing life. Akkun" is a part of Kumagai's own childhood memories and traumas that still remain in him as an adult, a part of him that remains a child, an inner child-like existence. While people are constantly changing, the influences of their childhood experiences and environment survive inside their veins. Kumagai created this new work based on his view of the inner child as a symbol of "transmigration," the interweaving of all life. The inner child is also an existence that lies dormant in the hearts of all people. Viewers will encounter their "hidden self" through the "Akkun" series.
