A rotary impact tool according to one aspect of the present invention includes a motor, an impact mechanism, a drive unit, an impact detection unit, and a control unit. The control unit reduces a driving force for the motor caused by the drive unit when a count of impacts detected by the impact detection unit has reached a determination count set in advance, which is a value greater than one.
