Studies on exotic hadrons at Belle

In this talk, we will present updated results on exotic hadrons from the Belle experiment at KEK. First, we will present results from reanalysis of the Z(4430)+ resonance using the Dalitz plot technique. We have observed the signal peak with more than 6 sigma significance, consistent with our previous measurement. We will also present some more new results obtained by Summer 2009. Then, we will present on the plan for the upgrade of the KEKB accelerator and the Belle detector to the Super-KEKB and Belle II, and discuss future prospects of research in this area
