From the Autumn Kyushu Fair (ends on 28th Sep), this rolled up red bean filling encased in warabi mochi (made of bracken starch- a type of edible fern), then covered in Kinako (soy bean flour). It differs from true mochi made from glutinous rice.

Super soft texture as compared with typical chewy mochi. Couldn’t possibly hold its shape on its own if not for the filling inside. They also sell the warabi mochi with no filling, cut into cubes and tossed in Kinako powder.
