Justin Guarini, the runner-up on season one of "American Idol," will perform at the International Heart Expo 2007 to take place this weekend in Kanazawa City, Ishikawa Prefecture.

The International Heart Expo 2007 is a charity event that aims to take "direct action" to support children in developing countries. Volunteers from Japan and abroad will participate, The Japan Times reports.

Clothes made with silk from Cambodia and Ishikawa Prefecture's Komatsu City and designed by Japanese fashion designers will be on view. Children from Myanmar, Cambodia and Sri Lanka will model for the show.

"Direct action" is an approach advocated by Japanese Buddhist monk Gayuna Cealo, whose charity work includes the setting up of orphanages in countries such as Myanmar and Cambodia.
