introduced them to Japan and they were allowed to flourish due to the interest of powerful warrior elites. Musō Soseki (1275–1351) was a Zen monk who was advisor to both Emperor Go-Daigo and General Ashikaga Takauji (1304–58). Musō, as well as other monks, served as a political and cultural diplomat between Japan and China. Musō was particularly well known for his garden design. Another Ashikaga patron of the arts was Yoshimasa. His cultural advisor, the Zen monk Zeami, introduced the tea ceremony to him. Previously, tea had been used primarily for Buddhist monks to stay awake during meditation. Education In general, samurai, aristocrats, and priests had a very high literacy rate in kanji. Recent studies have shown that literacy in kanji among other groups in society was somewhat higher than previously understood. For example, court documents, birth and death records and marriage records from the Kamakura period, submitted by farmers, were prepared in Kanji. Both the kanji literacy rate and skills in math improved toward the end of Kamakura period. Some samurai had buke bunko, or "warrior library", a personal library that held texts on strategy, the science of warfare, and other documents that would have proved useful during the warring era of feudal Japan. One such library held 20,000 volumes. The upper class had Kuge bunko, or "family libraries", that held classics, Buddhist sacred texts, and family histories, as well as genealogical records. Literacy was generally high among the warriors and the common classes as well. The feudal lord Asakura Norikage (1474–1555 AD) noted the great loyalty given to his father, due to his polite letters, not just to fellow samurai, but also to the farmers and townspeople: There were to Lord Eirin's character many high points difficult to measure, but according to the elders the foremost of these was the way he governed the province by his civility. It goes without saying that he acted this way toward those in the samurai class, but he was also polite in writing letters to the farmers and townspeople, and even in addressing these letters he was gracious beyond normal practice. In this way, all were willing to sacrifice their lives for him and become his allies. In a letter dated 29 January 1552, St Francis Xavier observed the ease of which the Japanese understood prayers due to the high level of literacy in Japan at that time: There are two
