Differences in the shape of the two trees
Hinoki cypress, his branches are very characteristic, arranged in a whorl.

Also, when the Juniper's cold winter months arrive, its leaves will become the same as the usual ones of the Marsh Juniper. It will shrink to the size of a needle. The shape is like that of a fish scale. However, when you touch the white fuzz that grows on the leaves of the Juniper during the winter, it will feel smooth. These are some of the differences in shape between the two trees when compared to the Juniperus communis.
