Eisai was a significant Japanese Buddhist priest during the Heian and Kamakura periods. He is most famous for founding the Rinzai school of Zen Buddhism in Japan. This school is a Japanese branch of the Linji school from China. Eisai believed that Zen Buddhism could serve as a tool to protect and unify the country. He felt that the religious schools existing in Japan at the time were not working well. Through his work, he sought to bring Buddhism back to its moral foundations. His influence extended beyond religion into the daily lives of people through the introduction of tea.

Eisai's path to becoming a Zen master involved two major journeys to China. His first trip began in 1168 when he traveled to Mount Tiantai. He wanted to study the origins of the Tendai sect, which he had joined as a monk. This trip lasted only six months, but it taught him about the importance of the Chan school. Later, from 1187 to 1191, he made a much longer journey to China. During this second trip, he stayed at the Jingde Si monastery. There, he became a disciple of the master Xuan Huaichang. He was eventually initiated into the Linji school by the master Hsü an.

Upon returning to Japan in 1191, Eisai began establishing the foundations of Zen. He brought back important Zen scriptures and green tea seeds from his travels. He immediately founded Shōfuku-ji in Kyūshū, which was the first Zen temple in Japan. He also integrated specific monastic routines into his practice. These included prayer rituals and the recitation of sutras. These practices were based on the Rules of Purity from the Chinese Song dynasty. Later, in 1202, he founded Kennin-ji in Kyoto on land gifted by Minamoto no Yoriie.

Eisai faced significant challenges while trying to spread his new faith. He used careful diplomacy to try and gain respect from the Imperial court. However, he encountered violent opposition from traditional Buddhist schools like Tendai, Shingon, and Pure Land. To find more support, he moved to Kamakura in 1199. This area was home to the shōgun and the rising warrior class. These leaders welcomed his teachings with enthusiasm. Hōjō Masako, the widow of Yoritomo, helped him build Jufuku-ji, the first Zen temple in Kamakura.

Beyond religion, Eisai is credited with starting the tea tradition in Japan. He brought green tea seeds from China and planted them in the garden of the Ishigamibo at Seburiyama. He also wrote a book titled *Kissa Yōjōki*, or *Drinking Tea for Health*. Eisai viewed tea primarily as a medicine rather than just a drink. He lived during a time when many believed the world was in *mappō*. This was a period thought to be a time of spiritual decline. Eisai believed tea could help people cope with the ailments of this difficult era.

Eisai's medicinal theories about tea were based on Chinese science. He connected the five elements—earth, fire, water, wood, and metal—to five major organs. These organs include the liver, lungs, heart, spleen, and kidneys. He also linked these to five flavors: acidic, pungent, bitter, sweet, and salty. Eisai observed that the standard Japanese diet lacked the bitter flavor. He claimed this lack of bitterness caused many heart diseases. He argued that green tea was essential to provide the bitter flavor needed for a healthy heart.

Eisai's political and religious views were closely linked in his writing. He wrote a famous piece called *Kōzen Kokoku Ron*, or *A Treatise on Letting Zen Flourish to Protect the State*. This work was heavily influenced by the Humane King Sutra. This scripture states that preserving Buddhism is tied to preserving the country. Eisai used this idea to argue that Zen could help create a stable society. He wanted to convince the Minamoto military rulers to support a Zen-based government. Some historians view this writing as a form of nationalistic propaganda.

Eisai remained an eclectic thinker throughout his life. Even after founding the Rinzai line, he never gave up his status as a Tendai monk. He continued to use Tendai esoteric practices until he died in 1215 at age 74. His legacy lived on through his students, such as Eihei Dōgen. Dōgen also traveled to China and eventually founded the Sōtō school of Zen in Japan. Eisai is buried on the grounds of the Kennin-ji temple he founded. His life helped shape the religious and cultural landscape of Japan for centuries.
