NAKED WOOD™

Promoting Global Health through the sustainable use of wood for a Greener Earth

Why was the Sanjusangendo Temple in Kyoto, known as a temple for preventing headaches, using willow as the ridgepole? Why have the treasures of the Shoso-in, stored for over 1200 years, not decayed?

In a world where sustainable wood utilization is crucial, we have found the answer in NAKED WOOD.

なぜ、頭痛封じの寺として知られる三十三間堂は棟木にヤナギを使用していたのか。なぜ、正倉院の宝物は1200年以上も朽ちることなく保存されたのか。

世界で持続可能な木材活用が必要とされる中、私たちはその答えをNAKED WOOD に見出した。

Relationship between Japanese and trees 

In Japan, since ancient times, the gods have dwelt in the mountains and trees have been considered to be possessed by the gods. When a tree is cut down, people offer grains and pray to receive the life of the tree given by the god. Forests are nurtured by the abundant precipitation brought by the oceans surrounding the Japanese archipelago, and as the people of the forests, they have developed a close relationship with trees.

日本では古来、神は山に宿り、樹木が憑代と考えられた。木を伐採するには、神が与えた木の命をいただくために五穀を供え祈願した。日本列島を取り囲む海がもたらす豊富な降水量によって育まれた森は、森の民として木々と密接な関係を築かせた。

Promoting Global Health with Wood Volatile Compounds

NAKED WOOD™

As people suffering from physical ailments caused by the stresses of modern society seek healing in nature, the benefits of forest bathing are becoming increasingly well known. In 2022, in a joint research with Kyushu University, we found that people are affected by odorless volatile substances of wood (the effect is lost when the scent is felt). Wood finished in the traditional Japanese way (air dried planed finish without painting) retains many substances* produced by trees. In modern times, aspirin, an analgesic, is derived from the salicin in willow bark, while it has been discovered that the volatile substances from the cedar trees in the Shosoin Repository have preserved ancient treasures for many years. We named such wood "NAKED WOOD". Promoting the utilization of volatile compounds from wood for a healthier world – benefiting both people and forests.

*Plants, which cannot move, produce various chemical substances for survival. Since its birth, mankind has used these substances to create many medicines.

木材揮発成分で世界を健康にする

2022年、九州大学との共同研究から、木材からの無臭の揮発性物質に人が影響を受けていることを突き止めた(香りを感じると効果はない)。日本古来の方法で仕上げられる木材(天然乾燥カンナ仕上げ無塗装)には、樹木が作り出す物質が多く残っている。現代において、ヤナギの樹皮のサリシンから鎮痛剤アスピリンが作られ、正倉院のスギによる揮発性物質による防腐効果が、古い宝物を長年保存してきたことが解明された。我々はこのような木材を” NAKED WOOD “と名付け、木材からの揮発性物質を活かす木材活用で世界の人・森林を健康にする。

Living with NAKED WOOD™

NAKED WOOD HOUSE

We are utilizing not only coniferous trees but also broad-leaved trees for planing and finishing, without any coating, as an effort to carry on Japan's tradition of SHIRAKI (which refers to untreated timber) culture.
