We present results of direct imaging observations for HAT-P-7 taken with theSubaru HiCIAO and the Calar Alto AstraLux. Since the close-in transiting planetHAT-P-7b was reported to have a highly tilted orbit, massive bodies such asgiant planets, brown dwarfs, or a binary star are expected to exist in theouter region of this system. We show that there are indeed two candidates fordistant faint stellar companions around HAT-P-7. We discuss possible rolesplayed by such companions on the orbital evolution of HAT-P-7b. We concludethat as there is a third body in the system as reported by Winn et al. (2009,ApJL, 763, L99), the Kozai migration is less likely while planet-planetscattering is possible.
