We investigate the structure of the Λ(1405) resonance and [Formula: see text] phenomenology in the perspective of chiral SU(3) dynamics. Utilizing the chiral coupled-channel approach which well describes the [Formula: see text] scattering observable, we perform three different analyses to clarify the structure of the Λ(1405) resonance. The results consistently indicate the meson-baryon molecule picture of the Λ(1405). We argue the consequence of the chiral dynamics in [Formula: see text] phenomenology and the antikaon bound state in nucleus, emphasizing the important role of the strong πΣ interaction.
