The "Ohka," or "cherry blossom," was a weapon associated with users performing this action, earning it the nickname "Baka" from Allied troops. The Honno-Ji incident ended when (*) Oda Nobunaga performed this action, which is highly associated with Aokigahara forest. Performing the banzai charge effectively equated to doing this, and the "divine wind" that repelled Mongol invasions names a form of this action used to sink American ships, the kamikaze.
