Thujopsis dolabrata

Japanese hiba or Japanese false arborvitae is in the cypress or Cupressaceae family and is native to Japan, where it also is called asunaro, which is short for "asu wa hinoki ni narou", which translates as "tomorrow, let's become hinoki" (hiba being hinoki's poor cousin).

It is a dense, slow-growing understory conifer species generally less than 20 m tall, although it will reach 40 m on occasion.

• Hiba is closely related to Arborvitae (Thuja) but has broader leaves arranged in dessucate pairs, 3–10 mm long, emerald green above and white below with green stems and outer edges. Sprays are distinctly broader than those of Thuja.
• The species is monoecious, bearing both male and female flowers on the same plant. The males are pollen cones on the tips of branches; females are upright, ovoid, 7–15 mm long and 6–10 mm across with 6–12 thick scales.
• Bark is red-brown and peels in vertical strips.
