Zhu Zhiyu (Chinese: 朱之瑜; 1600–1682), courtesy name Luyu (魯璵), and commonly known as Zhu Shunshui (朱舜水; romaji: Shu Shunsui) in Japan, was one of the greatest scholars of Confucianism in the Ming dynasty and Edo Japan. Zhu remains the best remembered of the Ming political refugees in Tokugawa Japan and the one who contributed most to Japanese education and intellectual history.
