PROBLEM TO BE SOLVED: To provide a flushing water-circulating flush toilet continuously usable for a long period of time while effectively preventing the generation of a mal odor from a discharged filth. SOLUTION: A control device 10 drives a first pump 3 and a second pump 6 in turning-on of a seating switch 11 for detecting the sitting state of a user in a toilet seat to control the aeration/stirring in a first tank and the supply of flushing water from a second tank to a closet bowl. The control device 10 has an automatic aeration period monitoring means 10a for monitoring the period of automatic aeration and a waiting time counting means 10b for counting the waiting time up to execution of automatic aeration. During automatic aeration period, an aeration/flushing control means 10c drives the first pump 3 every fixed time to perform aeration, and when the seating switch 11 is turned on during waiting of aerating operation, the waiting time counting means 10b is reset once, and then set after turning-off of the seating switch 11.
