Where Zen and tea became one

During the Warring States period, the warlord Nagayoshi Miyoshi (1522–1564), who had brought the capital region under his control, consolidated his power by drawing the autonomous merchant city of Sakai into his sphere of influence. Reading the shifting winds of the age, the townspeople of Sakai skillfully balanced commercial advantage with self-governance, forming ties with warring lords when necessary to sustain the flourishing of their city's culture. Forged in the difficult navigation of a turbulent era, the political acumen of Sakai's citizens eventually gave rise to one of the most important currents in Japanese cultural history: the way of tea, or more precisely, the fusion of Zen and tea. What we think of today as the tea ceremony took shape much later; at its fountainhead lay an extraordinarily sophisticated cultural philosophy.

In 1557, to pray for the repose of his late father Motonaga, Nagayoshi founded Nanshuji, a temple of the Daitokuji branch of the Rinzai Zen school, in Sakai. The temple's roots reached back some thirty years earlier to 1526, when Kogaku Soko (1465–1548), a renowned Rinzai monk of Daitokuji in Kyoto, opened a hermitage in Sakai called Nanshuan. When Soko's initial successor died young, another of Soko's disciples, Dairin Soto (1480–1568), succeeded him as the third master — and from this succession, a pivotal chapter in cultural history began.

Nagayoshi was deeply devoted to Dairin Soto and invited him to serve as founding abbot when Nanshuji was established. Situated near present-day Shukuin-cho in Sakai, Nanshuji grew under Soto's guidance into a grand complex that stood, in the midst of a war-torn age, as a symbolic link between the Miyoshi regime and the merchant culture of the city. It served at once as the family temple of the Miyoshi clan and as the spiritual and cultural pillar of Sakai. Although Nanshuji burned to the ground in 1615 during the Summer Campaign of the Siege of Osaka — the final battle between the Toyotomi and Tokugawa houses for supremacy over the realm — it was rebuilt in the early Edo period through the efforts of the Zen monk Takuan Soho (1573–1645), preserving its deep bond with the city.

Why did the wellspring of today's way of tea emerge from Nanshuji? The answer lies with its founding abbot, Dairin Soto. A celebrated master of Rinzai Zen, Soto began opening the halls of Nanshuji to Sakai's tea men — who were, at bottom, merchants — as a place to practice seated meditation. This suggests that Nanshuji was functioning as something far more than an ordinary house of worship. If we look at the temple solely as a religious institution, its true role remains invisible.

Behind this lay a broader historical reality: throughout the Muromachi period (1336–1573) under the Ashikaga shoguns, Zen temples served a vital role that went well beyond religion, acting as gateways to the most advanced culture of the Chinese continent — poetry and prose, Confucian scholarship, calligraphy, ink painting, architecture, and garden design. In effect, Zen temples functioned as salons where the intellectuals and cultural figures of the day gathered, and Zen monks acted as the transmitters of that continental learning. Unlike today, the cutting-edge culture arriving from China was not open to the public; only a privileged few had access to it.

Thoroughly versed in this cultural tradition, Soto turned Nanshuji into a salon where the thinkers and men of culture in Sakai could meet and converse. In doing so, he became one of the prime architects of the fusion of Zen and tea from which the way of tea would grow. In that era, the quiet precincts of the temple became a social gathering place for the townspeople, where Zen monks, merchants, and tea masters debated philosophy and art. Because the grounds of a Zen temple were a world apart, shielded by religious authority from political interference, they also provided cover for confidential meetings of every kind. In such gatherings, the tea served to guests became indispensable — acquiring a weight capable of swaying political decisions themselves.

With its dry-landscape gardens and tearooms, the compound of Nanshuji offered a distinctive space where Zen aesthetics and the sensibilities of chanoyu (茶の湯) — the art of tea — flowed together. Such spaces became the nerve center of Sakai's townspeople culture and exerted a lasting influence on the philosophical foundations of the way of tea. Nearly every tea master living in Sakai at the time is said to have trained in Zen under Soto, and through trial and error they began weaving the spiritual discipline of Zen into the practice of tea. Kitamuki Dochin (1504–1562) and Takeno Joo (1502–1555), two Sakai figures who laid the groundwork for the later culture of tea, both studied under Soto, and this current reached all the way to Sen no Rikyu (1522–1591), who brought wabi-cha (侘び茶) — the austere, wabi style of tea — to completion. Indeed, the Buddhist name Soeki, which Rikyu bore around the age of twenty-three, is thought to have been bestowed upon him when he practiced Zen under Soto at Nanshuji.

Soto's style of Zen prized finding the spirit of Buddhist practice in the midst of everyday life, and he held that chanoyu, too, could be practiced as "everyday Zen." At the heart of this view stood the philosophy of chazen ichimi (茶禅一味): the idea that tea and Zen share a single taste, a single essence. The mindfulness brought to each gesture at a tea gathering, the quiet absorption of boiling water and whisking a bowl of tea with no distraction — all of this was elevated into a philosophical ideal. At Nanshuji, the spiritual lineage planted by the monks of Daitokuji converged with the ethos of chazen ichimi, making the temple the crucible in which the foundations of the way of tea were forged. That Zen, which had flowered so richly in Song-dynasty China, crossed the sea to Japan and fused with the art of tea in the merchant city of Sakai is a fascinating chapter of cultural history.

It should be added that the other great tributary of chazen ichimi came from Murata Juko (1422–1502), who is regarded as the founder of wabi-cha. Originally a monk of the Pure Land school in Nara, Juko later practiced Zen under the famous iconoclast Ikkyu Sojun (1394–1481) of the Daitokuji line, and through that encounter sought the realm where tea and Zen become one. The heir to Juko's thought was Takeno Joo, the wealthy Sakai merchant and tea master. Joo carried Juko's vision forward, deepening it into the spirit of wabi and sabi within the art of tea. Seen in this light, long before Sen no Rikyu — who is revered today almost as a god of tea — the cultural soil had already been richly prepared.

Joo had deep ties to Zen from early on, having received the character "Jo" in his name from Kogaku Soko, the founder of Nanshuan. At Nanshuji, he threw himself so wholeheartedly into Zen training under Soto that he was granted the lay Buddhist title Ikkan Koji. His approach to tea, which turned away from the prevailing taste for luxury and display in favor of stillness, was known as jakucha (寂茶), a style born directly from the quietude of Zen. Deeply moved by Joo's example, the townspeople of Sakai learned to prize unpretentious, domestically made utensils over costly Chinese imports, carrying wabi-cha — the communion of minds within a spare, unadorned tearoom — a great step forward. What was taking place at Nanshuji in Sakai was no mere merchant pastime, but an elevated act of cultural creation that united inner spiritual discipline with the art of receiving a guest.

Anchored in the teachings of Zen, the spirituality of chanoyu grew ever firmer, eventually resonating deeply with the warrior class, whose temperament was naturally drawn to Zen. Under the patronage of hegemonic warlords such as Oda Nobunaga and Toyotomi Hideyoshi, this tradition reached its full flowering — and it was on this stage that Sen no Rikyu played his celebrated role. Chazen ichimi was a cultural and philosophical synthesis of Zen and tea, and the way of tea built upon that foundation had its womb in Nanshuji in Sakai, from which its influence continues to flow down to the present day.

Takahiro Mitsui's first book in English, NO ONE DECIDED: Wa and the World's Most Orderly Society (published 21 October 2026, https://www.amazon.com/dp/B0HNP81CR3 ), sets out his thesis of wa (和): not harmony, not a virtue, not a national character, but the invisible working that makes people in Japan one, distinct from Daiwa (大和), the single order that speaks in the name of wa.

In Takahiro Mitsui's own words: “Wa is not harmony. No one decided, and yet it is decided.” (Project 2049 Vol.3, https://project-2049.takahiromitsui.com/vol-3 )

In Takahiro Mitsui's own words: “Daiwa is single. To be single is to leave no yohaku. But wa is one. So it is many, and an abundant yohaku remains.” (NO ONE DECIDED: Wa and the World's Most Orderly Society (2026), ch. 21, https://www.amazon.com/dp/B0HNP81CR3 )
