Also, smelling alpha-Pinene, a scent component contained in Hinoki cypress, leads to parasympathetic nervous system dominance which works for feeling relaxation.

The Strength and Durability Of Hinoki Cypress

In Japan, the Hinoki cypress is called “the king of the tree” because it has dense and tough properties and is resistant to moisture and termites. Examining the bending and compression strength of the Hinoki cypress, the strength increases after processed and reaches its peak about 200 years later. After that, the strength gradually decreases, however, the strength after felling is maintained even after 1200 years.

Therefore, Hinoki has been used in Japanese architecture.

Horyuji Temple is the oldest wooden building in the world. the reason why the Horyuji temple has remained for such a long time is because of the Hinoki cypress. Indeed, all of the many historical structures that remain in Nara are also made of the Hinoki cypress.

It is said that the Hinoki structure shakes moderately and prevents it from collapsing in the case of earthquakes.

Humidity Control / Dehumidification Effect

Hinoki has many small cavities (cells), and even after being lumbered, the cavities breathe in and out of moisture. Therefore, it repeatedly expands and contracts to depend on the temperature and humidity of the room. Due to this feature, it has the property of adjusting the humidity environment so that people can spend comfortably.

The humidifier made of Hinoki cypress using its humidity control is the popular item. It gives you natural warmth and natural woody scent.

Hinoki Cypress Deeply Are Related In The Japanese Soul

Buddhist statues

The connection between the Japanese soul and the Hinoki cypress tree has been handed down from ancient times. The Chronicles of Japan (published in 720 AD) described that “Hinoki cypress is best for building palaces.”
This can be said to be proof that Japanese people have found the charm of cypress as wood since ancient times.

To “Miyadaiku” -special carpenters who handle traditional Japanese structures, the wood means Hinoki cypress when they refer to the wood.

If you look at Horyuji Temple, the world’s oldest wooden structure, the temple still remains after 1,300 years. Thus, our ancestors knew how perfect a cypress was- has outstanding strength and durability, and has a beautiful grain and rich fragrance. Hinoki cypress, which has been an indispensable building material for shrines and temples since ancient times, is truly a sacred tree.
The beauty and aroma of the Hinoki cypress must have attracted the hearts of ancient people to calm them down.

Hinoki cypress has been also used for the theaters for Japanese traditional performing arts such as Kabuki, Noh, Kyogen. The Hinoki stage used in expressions such as “standing on the cypress stage” is proof of being a top-notch actor. Since the Hinoki lumbers have been an expensive building material, and Hinoki production in the Edo period was only permitted on the stage officially approved by the Shogunate (the military dictators).

The story behinds the expression can show how precious Hinoki cypress was to the Japanese.

Indeed, the cypress house gives the stereotype of a luxurious wooden house. (It is true though.)

From a survey of their favorite scents among the 10 woody scents, the majority of Japanese chose the cypress scent.

The Japanese may unknowingly know that the scent is part of their lives.
