description
The Japanese tree of life is a shrub or tree with a stature height of up to 18 meters. It has a narrow, pointed and dense tree crown . The individual branches are curved sickle-shaped and have irregular branches. The scale sheets are yellowish-green and dull, on the underside they have gray-green stomata . The edge leaves are blunt, which distinguishes them from the pointed ones of the giant tree of life ( Thuja plicata ).
The flowering time is in March. The Japanese tree of life is single sexed ( monoecious ), so male and female cones are located on one plant specimen. The male cones are first dark red and later yellow and are very small - only about 0.1 centimeters wide. The female cones, which consist of ten to twelve seed scales, are egg-shaped and about 1.2 centimeters tall, while they change color from bright green to dark brown as they ripen. The seed is 5 to 6 mm long with 6 to 7 × 2 to 2.5 mm large with wings.

Thuja standishii was listed as not endangered on the IUCN Red List of Endangered Species in 1998 .
