This report summarizes the most important results presented at the recent conference held at the Yukawa Institute of Theoretical Physics in Kyoto, devoted to the recently confirmed light sigma resonance. Remarkably, all speakers at this meeting took the light sigma for granted and many mass and width estimations near 500 MeV were presented. We emphasize that if the light and broad sigma is accepted as a true resonance it explains many basic problems of low energy hadronic physics in a simple way, especially if the linear sigma model is used as an approximate effective low energy theory.
