Fodor's Expert Review Hanzo Gate

The house of Hattori Hanzo (1541–96) once sat at the foot of this small wooden gate. Hanzo was a legendary leader of Ieyasu Tokugawa's private corps of spies and infiltrators—and assassins, if need be. They were the menacing, black-clad ninja—perennial material for historical adventure films and television dramas. The gate is a minute's walk from the subway.
