To provide a fuel tank system capable of reducing the discharge of fuel vapor to the atmosphere.SOLUTION: The fuel tank system includes: a fuel tank; a fuel feeding port through which fuel is fed into the fuel tank; an inlet pipe causing the fuel tank to communicate with the fuel feeding port; a canister for adsorbing fuel vapor from the fuel tank; a circulation passage causing the inlet pipe to communicate with the fuel tank to guide the fuel vapor to the inlet pipe; a vapor passage communicating with the canister and guiding the fuel vapor to the canister; an atmosphere passage causing the canister to communicate with the atmosphere; a first on-off valve for opening/closing the atmosphere passage; a purge passage causing the canister to communicate with an internal combustion engine; and a second on-off valve for opening/closing the purge passage.SELECTED DRAWING: Figure 1
