1. A three-dimensional data encoding method, comprising:
generating pieces of encoded data by encoding subspaces obtained by dividing a current space including three-dimensional points; and
generating a bitstream including the pieces of encoded data and pieces of first information each of which corresponds to a corresponding one of the subspaces,
wherein each of the pieces of first information indicates whether the bitstream includes second information indicating a structure of the corresponding one of the subspaces, and
wherein the second information includes origin coordinates of the corresponding one of the subspaces, the origin coordinates including a first origin coordinate, a second origin coordinate, and a third origin coordinate of the corresponding one of the subspaces.
