A closed tank system includes: a fuel tank; a canister adapted to adsorb evaporative fuel generated in the fuel tank; a fill-up limiting valve provided inside the fuel tank so as to be communicated with the evaporative fuel discharge passage and adapted to operate to close the evaporative fuel discharge passage when a fuel level reaches a predetermined full tank liquid level; a shut-off valve adapted to operate to open or close the evaporative fuel discharge passage; a fuel remaining amount sensor adapted to detect a remaining amount of fuel; and a hardware processor that causes a control section to carry out control for allowing the shut-off valve to be opened or closed. The hardware processor causes the control section to inhibit the control for allowing the shut-off valve to be opened when an engine is in operation and the detected remaining amount of fuel exceeds a predetermined threshold.
