An irradiation apparatus includes a shielded object detecting unit, an illumination setting unit, an irradiating device, and an illumination controlling unit. The shielded object detecting unit detects a shielded object. Glare is allowable to the shielded object at an upper limit of illumination brightness or less. A driver can visually recognize the shielded object at an lower limit of the illumination brightness or more.
