A tilting pad journal bearing includes a pads disposed on the outer circumferential side of a rotating shaft, pivots supporting pads such that the pads are tiltable, a plurality of guides disposed between pads, and a casing. The pads have an oil passage extending from side to side in the circumferential direction, the guides having first and second guide passages. The first guide passage introduces lubricating oil from an oil-supply hole of the casing and exhaust it to the oil passage of the pad adjacent to the guide on the other side in the circumferential direction. The second guide passage introduces lubricating oil from the oil passage of the pad adjacent to the guide and on one side in the circumferential direction and exhaust it to between the inner circumferential surface of the pad on the other side and the outer circumferential surface of the rotating shaft.
