Low density states near the 3alpha and 4alpha breakup threshold in {sup 12}C and {sup 16}O, respectively, are discussed in terms of the alpha-particle condensation. Calculations are performed in OCM (Orthogonality Condition Model) and THSR (Tohsaki-Horiuchi-Schuck-Roepke) approaches. The 0{sub 2}{sup +} state in {sup 12}C and the 0{sub 6}{sup +} state in {sup 16}O are shown to have dilute density structures and give strong enhancement of the occupation of the S-state c.o.m. orbital of the alpha-particles. The possibility of the existence of alpha-particle condensed states in heavier nalpha nuclei is also discussed.
