We predict that the YORP thermal-emission effect can be directly detected through a measurable increase in the rotation period of the several-hundred-meter near-Earth asteroid 25143 Itokawa. The fractional change of Itokawa's rotation rate in between 2001 and 2004 should be $(1{-}2)\times 10^{-4}$, significantly larger than its currently estimated uncertainty $\simeq$$ 5\times 10^{-5}$. The corresponding change of sidereal rotation phase, normalized to unity in a cycle, is $\simeq$$ (0.09{-}0.25)$ in January 2004, producing $\simeq $$(1{-}3)$ h delay of lightcurve maximum.
