Diversity of Japanese Forests

It is perhaps a little known fact that approximately 67% of Japan’s landmass is covered by forests, making Japan the second most-forested country in the world following Finland. Furthermore, Japan’s forests are extremely diverse largely due to the fact that the country stretches across a long span of distance from the northern island of Hokkaido to the subtropical Ryukyu islands (Okinawa) in the south.

We at Yuica extract essential oils from 9 different types of Japanese trees, both deciduous and coniferous (evergreen), that grow in the Hida region in central Japan. Even within this small area, there are various kinds of trees, allowing us to produce a wide range of aromatic notes for you to enjoy.
