There have recently been several anomalies in rare B decays, and lepton-universality measurements, specifically involving the b → sl+l− quark transition. These results tend towards a non-Standard-Model interpretation. The Belle II experiment is a next-generation b physics experiment located at SuperKEKB, an upgraded B factory e+e− collider, in Tsukuba, Japan. The first collisions are expected in early 2018 with full physics data expected in 2019. This document describes prospects for several rare B decays at Belle II including b → sl+l− processes and others, such as b → (s, d)γ and b → sνν . Areas where the Belle II program is complementary to that of the currently running LHCb experiment are highlighted. 000000669 6531_ $$arare decays 000000669 6531_ $$aelectroweak penguin decays 000000669 6531_ $$aradiative 000000669 6531_ $$aFCNC 000000669 6531_ $$aBelle II 000000669 6531_ $$aSuperKEKB 000000669 6531_ $$aflavour-changing neutral current 000000669 8560_ $$fsamuel.thomas.cunliffe@desy.de 000000669 8564_ $$uhttps://docs.belle2.org/record/669/files/BELLE2-CONF-PROC-2017-028.pdf 000000669 8564_ $$uhttps://docs.belle2.org/record/669/files/BELLE2-CONF-PROC-2017-028.gif?subformat=icon$$xicon 000000669 8564_ $$uhttps://docs.belle2.org/record/669/files/BELLE2-CONF-PROC-2017-028.gif?subformat=icon-700$$xicon-700
