 The species is now tried in the Japanese garden is the Japanese black pine or Thumberg pine (Pinus thunbergii) which in Japan is known as Kuromatsu (黒 松). It is a species that also in Japan and outside the archipelago now increasingly grown more as bonsai because it is a taxon very durable and easy to model. The black pine species is very representative of the Japanese garden easily differentiated by the modeling work and pruning of Japanese gardeners.

Pinus thunbergii called Japanese Black Pine, and in Japanese: Kuromatsu (黒松), is a species of woody plant native of coastal areas of South Korea and Japan (Kyushu, Shikoku and Honshū, but not Hokkaidō. Pinus thunbergii is big tree reaching heights of 25 m, rarely 35-40 m.

Among the most important we highlight the following: Pinus thunbergii ‘Kotobuki’, P.t. “Arakawa-sho”, P.t. “Kujaku”, P.t. “Miyajuna”, P.t. “Yoshimura”, P.t. “Nishiki-ne”, P.t. “Shio-guro” and P.t. “Iwai”.
