Izumo black pine [Powerswood]

Izumo black pine

The black pine is the prefectural tree of Shimane Prefecture.
Izumo is famous for being the home of Izumo Taisha Shrine, but it is also known for the myths of the White Rabbit of Inuyama and the transfer of the country, which appear in the Japanese mythological texts "Kojiki" and "Nihon Shoki." It is a mysterious and important place that is inseparably linked to ancient Japanese history.
It is said that wood cannot be used until it is at least 100 years old. The reason for this is that only the heartwood can be used; the white part of the sapwood is soft and contains a lot of moisture, so it is prone to mold.
This is an extremely valuable tree, becoming difficult to obtain due to a rapid decline in logs caused by pine bark beetles and salt damage.

Kuromatsu (black pine) is the prefectural tree of Shimane Prefecture.
Shimane's Izumo City is famous for its Izumo Taisha Shrine, but it is also known for Inaba's white rabbits and Kuniyuzuri myths that appear in the Japanese "Kojiki" and "Nihonshoki." Since ancient times, it has been an important, mysterious place, inseverable from Japanese history.
It is said that Izumo Kuromatsu wood cannot be used as a material until it has passed at least over 100 years of age – the reason being that only the heartwood is used, since the white part of the sapwood is soft and high in water content, which encourages the growth of mold.
This type of wood is very valuable and hard to obtain, because the amount of pulpwood available has radically declined, due to pine weevils and salt water damage.
