The design luminosity of the machine is 8 × 1035 cm−2 s−1 and the Belle II experiment aims to record 50 fb −1 of data, a factor of 50 more than its predecessor. From February to July 2018, the machine has completed a commissioning run and main operation of SuperKEKB has started in March 2019. Belle II is uniquely capable of studying the so-called "XYZ" particles: heavy exotic hadrons consisting of more than three quarks. First discovered by Belle, these now number in the dozens, and represent the emergence of a new cate- gory within quantum chromodynamics. This talk will present the prospects of Belle II to explore both exotic and conventional quarkonium physics. 000001730 8560_ $$fdoris.yangsoo.kim@desy.de 000001730 8564_ $$uhttps://docs.belle2.org/record/1730/files/BELLE2-TALK-CONF-2019-137.pptx
