Japanese researchers have uncovered a rare, centuries-old, Ninja oath pledging never to divulge the secrets of their spying and sabotage skills — on pain of divine retribution for generations. Kizu was a Ninja from a clan in Iga, a mountain-shrouded town near the ancient imperial capital of Kyoto. The oath was among some 130 ancient documents left to the university by the 16th head of the Kizu family. The existence of the oath was unveiled five decades ago in Japan but its whereabouts were unknown until now, according to Takao. Inosuke, who submitted the oath, was the fifth head and last Ninja from the Kizu family.
