  After the major success of B-factories to establish the CKM mechanism and its
proven potential to search for new physics, the Belle II experiment will
continue exploring the physics at the flavor frontier over the next years.
Belle II will collect 50 times more data than its predecessor, Belle, and allow
for various precision measurements and searches of rare decays and particles.
This paper introduces the B-factory concept and the flavor frontier approach to
search for new physics. It then describes the SuperKEKB accelerator and the
Belle II detector, as well as some of the physics that will be analyzed in
Belle II, concluding with the experiment status and schedule.
