摘　　要：In the past 20 years,many new hadrons that are difficult to explain within the conventional quark model have been discovered in the quarkonium region;these are called exotic hadrons.The Belle I experiment,as the nextgeneration B factory,provides a good platform for exploring them.The charmonium-like states can be produced at Belle I in several ways,such as B meson decays,initial-state radiation processes,two-photon collisions and double charmonium production.Bottomonium-like states can be produced directly in e^(+)e^(-) colliding energies at Belle I with low continuum backgrounds.Belle I plans to perform a high-statistics energy scan from the BB threshold up to the highest possible energy of 11.24 GeV to search for new Y_(b)states with J^(PC)=1^(--),X_(b)[the bottom counterpart of χ_(c1)(3872),also known as X(3872)]and partners of Z_(b)states.We give a mini-review on the status and prospects of exotic hadrons at BelleⅡ.
