I present the images of protoplanetary disks around intermediate-mass stars with ages of a few to several million years, collected from Subaru and ALMA. Disk spatial/density structure is an important key to understand how disks evolve possibly under mutual interaction with new-born planets. In our near-infrared observations, rich structures have been uncovered such as radial gaps and spiral arms in remnant envelopes or disks. The strong non-axisymmetry has also been found with ALMA in dust continuum for a few disks with wide gaps, suggesting localized accumulation of dust particles. Although the sample size is still very small (~10), gaps and non-axisymmetry seem common, implying that the significant fraction of disks harbor stellar/planetary-mass companions, or planet-forming activity is already triggered.
