服部正成
After his death on 4 November 1596, Hattori Hanzō was succeeded by his son, whose name was also Masanari, though written with different kanji. He was given the title of Iwami no Kami and his Iga men would act as guards of Edo Castle, the headquarters of the government of united Japan. Hanzō is actually a name passed down through the leaders of the Hattori family meaning his father was also called Hanzō and so was his successor. Indeed, there are five people known as Hattori Hanzō throughout history
