Abstract: According to one embodiment, a wireless power transmission system includes a first resonator and a second resonator, an adjustment circuit and an adjuster. The first resonator includes a first inductor. The second resonator includes a second inductor. The adjustment circuit includes a third inductor that receives AC power from the first inductor through a coupling with a first mutual inductance, a fourth inductor transmitting the AC power to the second inductor through a coupling with a second mutual inductance, and a capacitor being connected in series with the third inductor and the fourth inductor. The adjuster adjusts at least either one of the first mutual inductance or the second mutual inductance.
