In this iconic and rare print, Miyamoto Musashi (1583-1647), famed as a sword master and inventor of the two-sword style of fencing (nito-ryu), is shown plunging his sword into a giant whale off the coast of Higo (present-day Kumamoto prefecture). The clever composition shows the triptych format at its best; exaggerating the whale's form so that it almost completely fills the entire picture frame, producing an extremely powerful image.
