“Yonaoshi Junan! Ninjoken,” premieres Thursday, Aug. 3, at 7:35 p.m.
Junan, a former instructor of swordplay for the Shogun family, went to Nagasaki to study medicine. After returning to Edo he becomes known to be highly skilled doctor since he is the medical examiner for the magistrate’s office. But no one knows of his “dark” side: he goes out and punishes evildoers using his secret weapon . . . “needle of death.” Fully subtitled in English.
