Hakubundo on Kapiolani is a little Japanese store that carries all types of Japanese materials, including comic books, oragami papers, stamps and other gift items. The prices are pretty expensive but they often hold sales, so you can pick up some cool stuff for a little cheaper. As the other reviewer mentioned, Girls Day and Boys Day is probably one of their bigger events and that's when they sale special items like fish lanterns.
It is one of the few Japanese craft stores left on the island.
