In 1615 the lord of Owari ate this tree's nuts before going to war, and his successors kept eating them every New Year for two and a half centuries. The signboard records it plainly: Tokugawa Yoshinao, first lord of the Owari branch, took the nuts of this kaya before setting out for Osaka, and the summer campaign that followed finished the Toyotomi and settled the Tokugawa on Japan for good. After that the Owari lords ate its nuts each January to open the year. The tree has been a National Natural Monument since July 1932. It splits into several trunks from the base, the form Japanese calls a broom kaya or a thousand-stem kaya, and it is held up now by a crowd of props with wire on some of the limbs; the thin lower branches would be better off cut, and cannot be, because it is a national monument. What makes the New Year story land is what came next. Nagoya Castle and its honmaru palace burned in the air raid of 1945, and the kaya took the fire and did not die.
