Under the right, front of the engine, in front of the oil pan.
A Toyota\Lexus oil filter will have a drain spout that is snapped into the oil filter housing to drain the oil inside of it. Unscrew the cover, then the outer cap assy with a oil filter cap removal tool.
Replace the cartrige filter and orings.
