This is a Japanese video about Japanese walnuts.
On 25 July 2015 there was a storm in the Netherlands. In the botanical garden in Leiden, it damaged an old tree. It was a Japanese walnut tree.
In 1859, famous Japanologist Philipp Franz von Siebold had brought it from Japan to the garden. Now, the storm broke off its branches, and only the trunk still stands.
The botanical garden is investigating whether the tree can be kept alive.
