Bipolar explosion models for hypernovae (very energetic supernovae), associated with the black hole formation, are presented. The model features are as follows: (1) Fe-peak elements are ejected at high velocities to reach the surface region, while dense O-rich materials occupy the central region at low velocities. (2) The abundance ratios (Zn, Co)/Fe are enhanced while the ratios (Mn, Cr)/Fe are suppressed. The overall abundances are consistent with those observed in extremely metal-poor stars formed at the very early phase of the Galaxy, suggesting significant contribution of such explosions to the early Galactic chemical evolution. (3) Certain relations among the optical luminosity, the chemical composition, and the property of the central remnant are predicted. Such relations may serve for identifying possible gravitational wave emitters in the future.
