Sandai Shōgun
Sandai Shōgun is one of the oldest-known living bonsai trees. Considered one of the National Treasures of Japan, it is in the Tokyo Imperial Palace collection. A five-needle pine known as Sandai Shogun is documented as having been cared for by Tokugawa Iemitsu.
The tree is thought to be at least 500 years old and was first trained as a bonsai by, at latest, the year 1610.
