What is Slam Dunk: 10 Days After?

In December 2004, to mark Slam Dunk passing 100 million copies in Japan, Takehiko Inoue returned to his cast for one short epilogue, 10 Days After, set ten days after the manga's final chapter. He drew it in colored chalk on 23 blackboards in the classrooms of the former Misaki High School in Kanagawa, a closed school, and opened the rooms to the public for three days, December 3 to 5. More than 5,000 fans came to see drawings that were then wiped away.

The epilogue survived through its documentation. Coverage and the chalk art were printed in the February 2005 issue of Switch magazine, a documentary of the event reached DVD in May 2005, and the book Slam Dunk 10 Days After Complete followed on April 10, 2009 from publisher Flower, which remains the form in which the chapter is collected.

As an object it is the strangest on the Slam Dunk shelf: a manga chapter whose original art no longer exists, drawn for a milestone and an audience standing in a school corridor. The experience fed directly into Inoue's later museum work, where he treated exhibition walls as pages.
