Shunoku Sōen

Sōen returned to Kyōto in 1589 and resided at the Daisen-in and Jukō-in sub-temples of Daitoku-ji before founding a new sub-temple Sangen-in under the patronage of Ishida Mitsunari and Asano Nagamasa.^[1] While at Sangen-in, Sōen founded Zuigaku-ji Temple in Omi Province, again sponsored by Mitsunari, and Yakusen-ji under the patronage of tea master and Sakai merchant Yamaoka Sōmu (?-1595).^[1]

Shunoku Sōen is famous for his deep connection with the Way of Tea.^[3] He held many tea wares now in the Sangen-in estate. In the collection of Sōen's poetry and Buddhist verses (gatha) entitled ‘Ichimoku Kō’ 一黙稿, he writes about the beauty of some of the most famous art objects in chanoyu history including the Chigusa, Miroku and Akebono tea jars and the Seitaka Katatsuki, and Enza Katatsuki tea caddies.^[3] The tea masters that studied Zen under him are a veritable who's who of chanoyu: Sōen bestowed Buddhist training names to Furuta Oribe (Kinpo 金甫), Ueda Sōko (Chikuin 竹隠), Kobori Enshū (Daiyū 大有), Sen Dōan (Min'ō 眠翁), Sen Sōtan, (Genshuku 元叔) and Yabunouchi Jōchi (Kenchū 剣中). Sōen was also closely associated with Imai Sōkyū and Sen Rikyū. In 1589, Sōen was the officiating priest for the opening ceremony of the Sanmon gate, reconstructed from funds donated by Rikyū.^[1] Three days after the opening, Sōen again officiated for the 50th anniversary memorial for Rikyū's father at the Sanmon gate.^[1]After the completion of the Sanmon gate (金毛閣), in the offering written by Shunoku Sōen at the request of Rikyū, thousands of households opent their door at once said this sentence , which angered Hideyoshi then became a turning point of the relationship between Rikyū and Hideyoshi. Finally Hideyoshi ordered him to commit ritual suicide. Rikyū's grandson, Sen Sōtan, was sent to live at Sangen-in under the supervision of Shunoku Sōen at the age of ten through the wish of Rikyū. The calligraphy inscription of Rikyū's famous portrait by Hasegawa Tōhaku was written by Sōen at the request of Sen Dōan.

Sōen died in 1611 at the age of 83. His grave is at Sangen-in.

As a spiritual leader, he did not create works of art for commercial purposes, so it is not appropriate to talk about his "most expensive work."

However, Shun'oku Sogen is renowned for his calligraphy and is considered one of the greatest Zen calligraphers in Japan's history. Some of his calligraphy works are highly valued and considered national treasures, but they are not sold in the market. Instead, they are preserved and exhibited in museums and temples for their historical and cultural significance.

Shun'oku Sogen is known for his contributions to the development and transmission of the tea ceremony in Japan, particularly the incorporation of Zen principles into the ceremony. One of his famous offerings is the "Jukoan Tea Ceremony," which emphasizes the Zen concept of "ichi-go ichi-e," meaning "one time, one meeting." This concept emphasizes the importance of being fully present in the moment and cherishing each encounter as a once-in-a-lifetime experience. The Jukoan Tea Ceremony is still practiced today and is considered a valuable contribution to Japanese tea culture.
