Ieyasu died at Sunpu in 1616 and was buried at Kunōzan. His enshrinement required decisions about a divine title and ritual form. Sūden supported a myōjin title, while Tenkai advocated the gongen form associated with Tendai Buddhism. Hidetada chose to seek court approval for a gongen title, and Tōshō Daigongen was selected from the court’s proposals.
Construction and ceremonial arrangements proceeded alongside that decision. In 1617 the founder was enshrined at Nikkō, where existing mountain worship and temples provided the sacred setting. Kunōzan remained a place of worship and received its own formal shrine ceremony later that year.
The title and shrines established lasting sites for honoring the Tokugawa founder. Hidetada’s government provided patronage, clerics supplied ritual precedents and the court authorized the designation. The elaborate Nikkō complex familiar today followed Iemitsu’s major rebuilding in 1634–1636. Its scale belongs to that later campaign rather than to the original enshrinement alone.
Ieyasu died in 1616. His body was first interred at Kunōzan in Suruga, the province around present-day Shizuoka, before the dynasty established its principal cult center at Nikkō in 1617. The burial rites and the choice of a divine title involved different authorities. Bonshun, a priest of the Yoshida Shinto tradition, participated in the initial ritual arrangements.
Ieyasu’s death in 1616 required the successors to decide how he would be worshipped. Sūden supported the divine honorific myōjin. Tenkai, a monk of the Tendai school, argued for gongen, a deity understood as a Buddhist manifestation. Hidetada ruled in favor of gongen. The government sought court authorization, then selected Tōshō Daigongen from the proposed titles. Clerical counsel, shogunal judgment and imperial procedures contributed different powers to the result. Sūden’s participation gave him a voice, but it did not give him the final decision.

In 1607 Razan encountered members of a mission from Joseon, the Korean kingdom, at Sunpu, Ieyasu's retirement center in what is now Shizuoka. Classical Chinese gave learned Japanese and Korean participants a way to communicate in writing when their spoken languages differed. Questions and poems could move across the linguistic boundary.
The visit followed Hideyoshi's invasions of Korea, which had ended in 1598. Its purpose included answering Japanese diplomatic correspondence and recovering people taken to Japan during the wars. Joseon called it an answer-and-repatriation mission. The familiar label 'communications envoys' groups it with a later series whose diplomatic circumstances changed over time.
Returning captives was part of the settlement, not a picturesque accompaniment to literary exchange. Research summarized by Ritsumeikan's Asia-Japan Research Institute describes more than six thousand people returning through different routes, including the missions and their own efforts. Others remained in Japan. A courteous exchange between scholars took place alongside these unfinished human consequences of war.
Tsushima, the island between Japan and Korea, supplied essential intermediaries. Its ruling Sō family depended on Korean trade and maintained contacts that the Tokugawa government could not readily replace. Envoys crossed a chain of official instructions and local negotiation before they met a scholar such as Razan. His contribution belonged within that larger process.
The shared written culture could make disagreement precise. A title or a historical reference carried assumptions about which ruler stood above another. Korean representatives had their own diplomatic standing to defend. Razan's early contact helped establish a field of work that would become more important in the 1630s, when the shogunate scrutinized the documents passing through Tsushima.
At Ieyasu’s instruction Sūden composed the declaration against Christianity associated with the traditional year 1613. It was promulgated in Hidetada’s name, a sequence distinguishing the founder’s decision, the monk’s formulation and the shogun’s order. The text invoked a country founded upon deity worship, Confucian learning and Buddhism, presenting Christian teaching as disruptive to its proper order. This was the government’s justification for exclusion. The document gave religious condemnation a form through which officials could act.
Construction and ceremonial arrangements proceeded alongside that decision. In 1617 the founder was enshrined at Nikkō, where existing mountain worship and temples provided the sacred setting. Kunōzan remained a place of worship and received its own formal shrine ceremony later that year.

The National Archives of Japan describes a dispute between Sūden, who favored a myōjin title, and Tenkai, who favored gongen. Myōjin designated an illustrious kami, or sacred deity. Gongen interpreted a deity as a manifestation of a Buddha or Buddhist being. Hidetada settled on the latter form; the imperial court then supplied alternatives from which the government selected Tōshō Daigongen.
One reason attributed to Tenkai was political. Hideyoshi had been worshipped under a myōjin title, yet the Toyotomi dynasty had fallen. The Archives illustrates the argument with a biography of Tenkai published in 1789, long after the decision. That retrospective text is evidence for how the explanation was preserved, not a transcript of a meeting in 1616.
Razan is often added to a simplified contest in which Confucian or Shinto learning loses to Buddhism. The archival account just described identifies Sūden and Tenkai as the advocates. Razan's studies of ritual and sacred tradition make him relevant to the intellectual setting, but this account does not establish his precise intervention in the decision. His continuing career cannot be explained through an imagined defeat.
The outcome kept Buddhist manifestation theory at the center of the founder's cult. Razan nevertheless remained a scholar in the same government. The combination was administratively workable: Tenkai's temple organization and Razan's teaching or documentary work supplied different capacities. Their coexistence is clear; a private rivalry governing every shared episode is not.
Seika died in 1619. Ishida Ichirō's account of Razan's thought places a clearer declaration of his allegiance to Zhu Xi's account of principle and material force after that death. Razan had read more widely than one school. His subsequent commitment was a choice within that learning, not the simple repetition of everything taught by his master.
Principle made things and relationships intelligible; material force accounted for their concrete forms. Moral cultivation required people to study and correct their conduct within everyday relationships. A ruler or parent held obligations as well as authority. In Razan's account, occupying a position without meeting its duties damaged order. Ritual trained conduct by giving those relationships repeated visible form.
These ideas supplied Tokugawa rule with a moral language beyond military victory. They could justify hierarchy, but also set standards for judging someone who exercised authority badly. The second function did not make subjects equal to rulers. Whether criticism could be safely voiced depended on power. Razan's account gave inequality an ethical justification while insisting that a superior's conduct mattered.
In 1629 he received the rank Minbu-kyō Hōin. Hōin was a high clerical designation, and he served under the name Dōshun. The government recognized a Confucian scholar through categories long used for learned clergy. His criticism of Buddhist doctrine did not prevent him from accepting that public status.
Historical disagreement · Did Razan establish one exclusive Tokugawa ideology?
His appointment is sometimes treated as the beginning of one exclusive Tokugawa ideology. The later school history does not support that compression. The Hayashi academy initially remained a family institution, and direct government administration came much later. Nor did Razan personally devise a uniform 'four-class system' covering all inhabitants. The familiar samurai-peasant-artisan-merchant formula omits other statuses and differences among jurisdictions.
His more demonstrable contribution was a teachable language of moral duties and hierarchy, sustained through a patronized scholarly household.
Emperor Go-Mizunoo granted Sūden the title Enshō Honkō Kokushi in 1626. Kokushi, or national teacher, was an honor bestowed upon a distinguished monk. Court recognition remained meaningful to someone serving the warrior government. The following year Sūden and Doi Toshikatsu, a senior government official, challenged the admission and advancement of monks at Daitokuji and Myōshinji. At these Kyoto Zen monasteries, imperial permissions recognized appointments and the right to wear purple robes, signs of elevated religious status. The challenge placed that practice against rules issued in 1613 and 1615.
Monks including Takuan Sōhō submitted a protest in 1628 to Itakura Shigemune, the government’s senior Kyoto official. Resistance continued, and in 1629 the government sent protesting monks into exile in the northeast. Sūden pressed for severe punishment. The sequence involved regulations, objections, negotiations and penalties rather than a robe alone. A symbol of religious distinction carried a dispute about the power to make appointments and the authority to require obedience. The punishment removed particular opponents from their communities.
Razan helped turn classical learning into a durable service for Tokugawa government. His teaching and work with documents supplied language and precedent for regulating warrior houses, communicating with Korean envoys and arranging family histories. His defense of hierarchy gave rule a moral vocabulary, while his compilations preserved earlier records and framed them within the victorious dynasty's interests.
The Hayashi household joined books, ritual, teaching and inherited access to rulers. Descendants and later patrons transformed that base into a more directly official institution: restrictions favoring the Chinese philosopher Zhu Xi's teaching came in 1790, and direct shogunal administration in 1797. Razan's importance lies in the service and scholarly lineage he established, not in personally imposing one uncontested doctrine on every aspect of Tokugawa society.
Tenkai helped organize the Buddhist institutions and rites through which the early Tokugawa dynasty represented its authority. His Tendai explanation of Ieyasu's posthumous cult joined religious learning with shogunal resources and court recognition. Nikkō's worship linked the ruling successors with their founder, while Kan'ei-ji established a major eastern Tendai center beside Edo, now Tokyo.
The complete Buddhist canon printed in Japan was another enduring achievement. It depended on inherited Chinese texts, skilled printing work and support that continued after his death. Tenkai secured a central place for Tendai without monopolizing Tokugawa religion: other Buddhist institutions retained funeral and prayer roles. The temples, rites and books show how religious expertise could become a durable organization rather than only personal access to a ruler.
