Yes indeed Mauro. In fact it is my third kozuka with the same topic! ( from Internet: Lovely scene of the warrior Kojima Takanori kneeling beneath a cherry tree, having just written a poem on a tree's trunk. Takanori was a loyal supporter of the exiled Emperor Go-Daigo, and attempted to rescue him while he was being transported to a remote location. The samurai was able to sneak into the camp, but could not reach the emperor, so according to legend, he carved a poem of encouragement in Chinese for the emperor on a cherry tree. In the morning, the guards found the poem but could not read Chinese, but the emperor could, and was heartened by the message. A shower of delicate petals falls down over him in the cool evening breeze, and a full moon glows softly overheard.)
