To observe the light of a country

"Why do you travel?"

How would you answer so simple a question?

For the past few years I have moved through every corner of Japan, turning over the essence of tourism. The call for a uniform, shared experience mediated by social media still carries real weight. Yet some travelers feel uneasy with that mainstream, and they should not be lumped in with tourists.

In Japanese, going to different places to see and learn is called kanko (観光). The word comes from a line in the Chinese Book of Changes: 観国之光 利用賓于王. In modern terms, it means to observe the light of the country, the society and the people you visit, and to learn from it as a guest. To observe the light is also to observe the shadow. You must not lean too far toward either, and a traveler needs self-restraint and respect for others and for other countries.

Set the thought of yin and yang at the base of travel, and keep yourself at the middle way within the streets you visit. Through this practice you gain real learning, unlike the self-serving traveler of today. Kanko, in its original sense, is learning, and it is not one-sided consumption.

What you learn differs from person to person. It changes with each person's own nature, and it must not be swayed by what someone else says. Kanko is input, but it always presupposes output. Output is often misunderstood: it does not mean sharing travel photographs on Instagram or Substack.

It means that when the journey is over and you are back in the country, the society, the community and the relationships where you live, you put what you learned into practice for a better future. That is the essence of kanko.

This year, people in the tourism industry who had hit a wall asked me for ideas about "the next tourism," and I have been making new proposals, mainly in the Kansai region. What I start from is the essence of kanko I have just described. It differs from the conventional view that chases "numbers," such as visitor counts and sales.

Take Osaka, where I live myself. Namba, Shinsaibashi, Umeda and Shinsekai, the main tourist districts, were historically under the sea. Nearly every tourist visits them, but the real Osaka is not there.

So I want to follow the story usually told of Osaka's founding from my own angle. Today's name is written 大阪, but it was once 大坂. The oldest appearance of the name is in the Gobunsho, written by Rennyo in 1496. It did not at first denote a region, but thanks to the many achievements of Rennyo, a charismatic religious figure, the name Osaka spread in no time.

The greatest of those achievements was the building of Ishiyama Honganji, a large temple on the site of today's Osaka Castle. Rennyo was a monk of Jodo Shinshu, the school whose founder was Shinran. He was the eighth head of the Honganji branch of Jodo Shinshu and the eighth gate master of the Otani branch, one of the great figures of the Buddhist world of his day. To read the history of Osaka, we first need to set out what Honganji is.

Honganji began not as a temple but as a grave. When Shinran, founder of Jodo Shinshu, died in 1263, a stone tower was raised near the northern side of an area called Toribeno in the Higashiyama hills of Kyoto, and his remains were placed there. Toribeno was part of the huge cemetery that lay around Kyoto at the time, and this place was called Otani.

This history bears directly on the temples of Kyoto. Walk from Kyoto Station toward the city and you see two huge temples facing each other across the street, Nishi Honganji and Higashi Honganji. Both are Jodo Shinshu, but their history is intricate and tangled, and after long ages of confusion the eastern one calls its school the Otani branch of Shinshu and the western one the Honganji branch. Originally, though, Honganji had no west and no east. What does that mean?

The point is that Shinran himself founded neither a temple called Honganji nor a school called Jodo Shinshu. He lived to the end as a disciple of his teacher Honen. After spreading the teaching in the Kanto region, he spent his last years in Kyoto devoted to writing. He had no temple and formed no organization. Shinran was made into a religious order only after his death.

The order began about 1272, nine years after his death. A woman named Kakushinni, Shinran's youngest daughter, made a major decision with the help of his disciples and the followers in Kanto, where he had taught. She moved Shinran's grave from Otani, reburied his remains, and built the Otani Mausoleum there.

The land of the mausoleum was land she had received from her husband. So Kakushinni, Shinran's daughter, gave the land, the Kanto disciples raised the funds, and together they built the Otani Mausoleum to enshrine Shinran. This was the moment the history of Honganji began.

The complication is that the real owners were the Kanto followers as a group (called the Takada branch), and Kyoto had no owner. So a special post called rusushiki (留守職) was created on the Kyoto side to manage the mausoleum, with the rule that the keeper must be a blood relation of Shinran.

But we should not overlook the conditions of the age. The era centered on Heian-kyo, today's Kyoto, was over, and the functions of a capital had shifted to Kamakura in the east. The Kanto people, long looked down on by the people of Heian-kyo, had already begun to hold a measure of real power. Kakushinni's decision thus created a distorted structure that would weigh heavily on later history.

When the mausoleum entered an age of political influence as Honganji, the distortion surfaced as a clash between "the legitimacy of the bloodline" and "the autonomy of the Kanto followers." The turning point came in 1321, fifty-eight years after Shinran's death. With the arrival of Kakunyo (1270–1351), Shinran's great-grandson, faith turned into a naked struggle for political power, and the age of rising warriors began.

In 1302 Kakue, Shinran's grandson, and Yuizen, his half-brother by a different father, fell into bitter conflict over the post of keeper of the Otani Mausoleum. It lasted seven years. In 1309 the Tendai temple Shorenin in Kyoto ruled that Kakue's eldest son, Kakunyo, would inherit the mausoleum. Enraged, Yuizen destroyed the Otani Mausoleum and fled to Kamakura, seeking the protection of the Kanto followers who were its real owners.

Kakunyo took the physical destruction of the mausoleum as his chance and set out a new plan to fulfill his political aim: to rebuild what was only Shinran's grave as a temple, the headquarters of an order. In 1312 he hung a plaque announcing the conversion. Fierce protest from Enryakuji on Mount Hiei forced him to take it down, but after twists and turns the conversion was carried out under Kakunyo's leadership in 1321, and the temple was founded under the name Honganji.

From then on the Honganji order called itself Honganji and began large-scale political activity. Kakunyo, politically skilled, secured the religious legitimacy of Honganji while quietly pursuing another measure: the legitimizing of lineage.

In the Kudensho, which he composed in 1331, two lineages are set out. One is the legitimacy of the religious lineage, called homyaku (法脈), the lineage of the dharma, running from Honen to Shinran and then to Kakunyo. The other is the bloodline, running from Shinran to Kakunyo. Calling himself the third head of Honganji, Kakunyo created the doctrine of the Honganji order. He set the teaching of Jodo Shinshu at the summit, and held that it had passed from Honen to Shinran and then come to rest in himself.

In other words, it was an ideology of authority: the legitimacy of Jodo Shinshu doctrine and the legitimacy of Shinran's bloodline both flow into me, and therefore Honganji is the main stream of Jodo Shinshu. Yet even after Kakunyo set up Honganji, for nearly the next 150 years it remained a minor power within Jodo Shinshu.

In fact, while the Takada branch of Shinran's disciples rose in Kanto, Honganji had to be content with treatment as a branch temple of Shorenin, a Mount Hiei affiliate. Independence was Honganji's cherished wish, and seizing the interests of Jodo Shinshu was essential for survival as well.

Honganji stayed weak, though, and followers did not gather in the years that followed. Then the charismatic figure I have mentioned appeared: Rennyo. When Rennyo was born, Honganji was in ruins, an order no one took seriously. In those circumstances he grew up in poverty, but in 1457, at forty-three, he inherited the leadership of Honganji from his father and set about reform at once. That reform changed the history that followed.

Honganji then was a branch temple of Shorenin and belonged to the Tendai line, so its main hall is said to have held Tendai images and scriptures as a matter of course. Aiming for Honganji's independence, Rennyo threw out the Tendai influence from the hall and burned it all. He also abolished the Tendai-style pyramid between head and followers. He met the followers who came to worship as equals, spoke with them, and spent his time on the different troubles each one carried.

This method can be seen as a reinterpretation and reenactment of the founder Shinran's achievement in creating soil that received ordinary followers broadly. Rennyo also did not teach difficult scriptural doctrine to his followers. He spread the teaching wholly through conversation and letters. For the Buddhist world of the time this was a groundbreaking media revolution, and it worked with great effect. But Rennyo's moves at Honganji provoked one order: Enryakuji.

From Enryakuji's side, one of its own branch temples, Honganji, had started to act on its own without permission, and that was provocation enough. Rennyo had by then burned the Tendai scriptures as well. Monks from Mount Hiei swarmed in and destroyed Honganji, and through their propaganda Honganji was cast as "a fanatical band that slanders the principal images of Mount Hiei and claims that only it is right." Rennyo barely escaped the religious persecution and fled to Omi in Shiga, next to Kyoto, where he was eventually hidden by Onjoji, long hostile to Mount Hiei.

In 1471 he went from Kansai to Yoshizaki in Echizen on the Hokuriku coast (now Awara City, Fukui Prefecture), built a gobo, a hall for the teaching, and began active mission work. With his coming, the wasteland of Yoshizaki grew quickly and prospered so much that a temple town formed almost at once. In this period Rennyo published two works and built his own network with followers through letters, with mass copying of texts at the center of spreading the teaching.

Rennyo's conviction that dialogue should be between equals had enormous influence on people who could not read, and it laid the foundation for Jodo Shinshu to become, today, one of the largest bodies in Japan. His steady work bore fruit. Pilgrims came to Yoshizaki Gobo from across the country, and Yoshizaki, where nothing had been, was transformed into a great religious city.

Life in Hokuriku went well, but in 1473 the distorted structure carried by Jodo Shinshu burst into a problem. Surprisingly, the trigger was not a fight within Jodo Shinshu but an internal quarrel in the Togashi clan, the shugo daimyo who ruled Kaga Province. Yoshizaki, where Rennyo was active, lay right on the border between Echizen and Kaga, so he was bound to be drawn in.

The Togashi were split, and the elder brother Masachika Togashi and the younger Kochiyo Togashi fought bitterly over the headship of the family. The direct cause was the Onin War, the great civil war from 1467 to 1477. The capital had by then returned to the Heian-kyo side, but the war within the central regime split into two large camps: the Eastern Army, under the Hosokawa house, and the Western Army, under the Yamana house. The struggle for real power in Heian-kyo gradually spread to the provinces, and in the Togashi of Kaga, the brothers could not agree and split between the Eastern and Western Armies.

The elder, Masachika, was on the Eastern side, the younger, Kochiyo, on the Western. It was a provincial theater of the Onin War, and the fighting spread to Rennyo in an unexpected way. It is important to understand these circumstances.

For Rennyo's Honganji branch, two fatal risks had surfaced. One was that Kochiyo Togashi's side, the enemy, allied with the Takada branch of Kanto. The Takada branch was overwhelmingly the strongest within Jodo Shinshu, and its entry was plainly aimed at the interests of the Honganji branch at Yoshizaki and threatened to overturn its work at the root. Kochiyo also allied with Toshimitsu Kai, deputy military governor (the second most powerful man) of neighboring Echizen.

Both moves were ominous for Rennyo, who had worked at Yoshizaki on the border of Echizen and Kaga. At the time of the 1473 fighting, however, Rennyo rejected armed struggle, so the elder brother Masachika lost and was driven out of Kaga. But Masachika's expulsion was bad for Rennyo too, since a rival's rise would lead to suppression of the Honganji branch.

Sensing this, in 1474, the next year, Masachika offered Rennyo a condition: he would officially license the Honganji branch in Kaga, in return for intervening in the internal conflict. For a long time, even then, Rennyo was said to have opposed armed struggle, and seeing him as a pacifist was the general view. Recent research has begun to suggest that he may have led the armed intervention. When Rennyo's Honganji branch sided with Masachika, the tables turned, and Kochiyo lost and was driven from Kaga.

Political calculation cannot be missed here. Masachika asked Rennyo for support because he valued the skill that had built a religious city in a single generation. For Masachika, taking in a religious leader with a vast following and great influence was bound to work to his advantage. Rennyo is said to have hesitated over such open involvement in a political fight. The struggle was a proxy war within Jodo Shinshu, beyond being a provincial front of the Onin War. Rennyo, drawn into the quarrel, made a decision that changed the situation sharply.

His counterpart was a leader who changed his mind with the times. Masachika drove his rival out of Kaga with the help of the Honganji branch, but he feared the rising strength of the Honganji followers and, the year after his victory, in 1475, began harsh suppression. The Honganji followers were furious at Masachika for breaking his word. Renso Shimotsuma, one of Rennyo's followers, rallied them to bring Masachika down and ordered a simultaneous uprising, falsely in Rennyo's name. Masachika's side crushed it, and the Honganji followers of Kaga fled to neighboring Etchu (now Toyama). Furious at the great blunder, Rennyo excommunicated Renso and left Hokuriku himself.

Still, in the late 1480s the Honganji forces revived in Etchu, and in 1488 they destroyed Masachika with an army of more than 200,000.

After his successes and failures in Hokuriku, Rennyo's name became famous in many places and carried strong influence wherever he went. Moving from Hokuriku through Kansai, he threw his energy into mission work in Osaka, centered on Sakai, the international port of the day, and built Yamashina Honganji at Yamashina in Kyoto. The home temple of the Honganji branch was built as a fortified town, with walls seven meters high and a deep moat, with the pressure of Mount Hiei's warrior monks in mind.

His fame became the greatest in the Buddhist world, and in the Yamashina years he drew rapidly close to the Ashikaga shogunate. In 1481 came a turning point: the Jodo Shinshu bodies other than the Takada branch joined Rennyo's Honganji branch. The effective unification of Jodo Shinshu was achieved by a single man. When Rennyo was born, Honganji had no followers and was close to collapse, and this is how it made its miraculous revival.

Rennyo retired in 1489 but kept teaching energetically across Kansai and was revered by great numbers of people. He was a religious figure of a grassroots movement all his life, and the last project of his life now came to him: the Ishiyama Gobo. It was a small hall built on the northern tip of the Uemachi Plateau in Osaka, but it would in time move the founding history of Osaka itself. It was around then that the name Osaka was born.

In Rennyo's lifetime, however, the Ishiyama Gobo was only a small building, and in 1499, sensing death near, he moved to Yamashina Honganji. He died there in May of that year, at eighty-five. The Ishiyama Gobo, the last hall he built, would suddenly come into the spotlight in the harsh sixteenth century, when warriors fought one war after another.

The trigger was a religious conflict in 1532.

Yamashina Honganji of the Honganji branch, then at the height of its power, was destroyed by followers of the Hokke school. After this, Honganji was moved from Yamashina to Osaka, and in 1533 Osaka Honganji was founded on the site of the Osaka Gobo. This was the birth of Ishiyama Honganji. Thanks to Rennyo's achievements there were already many Jodo Shinshu believers, who saw Osaka as a new land, gathered there all at once and quickly formed an enormous temple town.

The land where Ishiyama Honganji was born was, in fact, the central point of ancient Osaka. Ishiyama Honganji was later overthrown by the warlord Hideyoshi Toyotomi, and Osaka Castle was built on its ruins and flourished as the main artery of Osaka throughout the Edo period. But it was not Rennyo who first set his eyes on this land. Its origin lies in the faith of people in remote antiquity. The history of Osaka has always begun and ended on this ground, renewing itself again and again down to the present.

Who, then, first set eyes on this land?

The moment we turn to the founding of Osaka from Osaka Castle, an Osaka quite unlike today's rises into view. Next time I will lead you into the ancient world of Osaka.
