  We overview the recent progress in the investigation of the antikaon dynamics
with single nucleon and with few-body nuclei, based on chiral SU(3) symmetry.
We first show how the Lambda(1405) resonance emerges from the coupled-channel
Kbar N-pi Sigma interaction. Next, we present the construction of an up-to-date
Kbar N interaction in response to the recent measurement of kaonic hydrogen.
Finally, we discuss the possibility of the antikaon bound states in nuclei from
the perspective of few-body physics.
