Koyamaki, or Japanese umbrella-pine, a very attractive evergreen tree and is popular in gardens, despite its slow growth rate, it's a unique conifer endemic to Japan. It can get to 15 - 27m tall and the main shoots bear whorls of long felxible cladodes - they look like and perform the function of leaves, but are actually composed of stem tissue. The small cones mature in about 18 months, and have flattish scales that open to release the seeds.
As with all woody plants, plant high exposing as much of the taper at the base of the trunk as possible. Allowing soil to accumulate round the base of a tree or shrub can be fatal.

General Point about Plant Hardiness: The commonly held belief that it's better to 'plant small' is perfectly true with herbaceous plants, but not necessarily true with woody plants. They need some 'wood' on them to survive severe cold - so plants of marginal hardiness in very cold areas should really be planted LARGER, rather than smaller, wherever possible.
