It is well known that a significant fraction of known extrasolar planets has significant orbital eccentricity. Moreover, recent measurements of the Rossiter-McLaughlin effect have revealed that about one-third of transiting planets have tilted orbits. Those eccentric or tilted planets are believed to evlolved through dynamical planetary migration due to the interaction with some kind of outer massive bodies. We started high-contrast direct imaging observations as a part of SEEDS (Strategic Explorations of Exoplanets and Disks with Subaru) project to search for counterparts of planetary migration mechanisms. In this talk, we report SEEDS first/second year results which may shed light on the relation between eccentricity/obliquity of inner planets and the existence of outer companions.
