  Recent works have suggested that the entanglement wedge of Hawking radiation
coming from an AdS black hole, will include an island inside the black hole
interior after the Page time. In this paper, we propose a concrete way to
extract the information from the island by acting only on the radiation degrees
of freedom, building on the equivalence between the boundary and bulk modular
flow. We consider examples with black holes in JT gravity coupled to baths. In
the case that the bulk conformal fields contain free massless fermion field, we
provide explicit bulk picture of the information extraction process, where we
find that one can almost pull out an operator from the island to the bath with
modular flow.
