上杉 (Japanese: Uesugi, Mandarin: Shàngshān) is the famous Sengoku-era samurai clan whose most celebrated head was Uesugi Kenshin (
上杉谦信, 1530-1578), legendary rival of Takeda Shingen (
武田信玄). When Japanese names like this appear in Chinese subtitles, the characters are read with their Mandarin pronunciations, not transliterated phonetically from Japanese.
