Omoikane, who formulates the plan for the rock cave, is the god who was first commanded to "think" in the darkness. When Amaterasu-Omikami hid in the Heavenly Rock Cave and the world was filled with calamity, the Kojiki recounts that the myriads of gods gathered at Ame-no-Yasukawara and there bade Omoikane, child of Takamimusubi-no-kami, to ponder. Amaterasu is at the center of the crisis, Ame-no-tajikarao is the one who reaches out at the end, and Ame-no-uzume is the one who turns the situation with her dance. However, it is Omoikane who places them all within the same strategy. He is not just a "god of wisdom," but the architect of crisis management. Omoikane's wisdom manifests not as quiet abstraction, but as highly specific procedural arrangements. After his deliberation, he has the long-crowing roosters of Tokoyo crow, takes hard rocks and iron of heaven, seeks the smith Amatsu-mara, has Ishikoridome make a mirror, has Tamanoya make magatama jewels, and tasks Ame-no-koyane and Futodama with divination, reciting norito prayers, and holding gohei offerings. These are not disjointed props. Just as Kokugakuin University's artifact commentary reads the Heavenly Rock Cave myth as an origin tale of rituals equipped with mirrors, jewels, cloth, iron products, and divination bones, Omoikane's plan is the compositional power to organize ritual technology into a single drama. The core of this compositional power is not in "persuading" Amaterasu, but in creating a situation where she approaches the doorway on her own. The mirror shows Amaterasu a strange presence outside, the jewels and cloth decorate the sacred space, the prayers establish order as words, and the dance and laughter break the enclosed atmosphere. Ame-no-tajikarao hides beside the door, but the only moment he can act is when Amaterasu attempts to step outside slightly. In other words, Omoikane's strategy is not one of coercion. It is a strategy to arrange the conditions that change the opponent's consciousness, creating a single point where the final force can act. It is significant that the Kokugakuin University annotations connect the meaning of Omoikane's name to "possessing the wisdom of deep thought" from an alternate account in the Nihon Shoki. Thoughtfulness is not merely having a lot of knowledge. It is the ability to read the situation, the stakeholders, and the procedures, thinking about what order of actions will cause the maximum change with the minimum destruction. At the Heavenly Rock Cave, merely breaking the stone door with military force was not the solution. The sun goddess's reappearance had to be established as a ritual, a council, a laugh, and the act of looking into a mirror. Omoikane is the god who reads that totality. His reappearance during the Descent of the Heavenly Grandson shows that this god's wisdom was not a one-time cleverness. Amaterasu-Omikami adds Tokoyo-no-omoikane-no-kami, Ame-no-tajikarao, and Ame-no-ishikadowake-no-kami alongside the sacred treasures, and commands that the mirror be worshipped as her own spirit. Furthermore, Omoikane is given the role of "taking charge of preceding affairs and governing." The god who assembled the ritual before the rock cave takes charge of the rituals centered around the mirror on earth, and engages in governance. Here, "thinking" transitions from mythological crisis response to the intellect of operating institutions. Ame-no-yagokoro-omoikane-no-mikoto at the Chusha of Togakushi Shrine preserves this character as a tactical god within mountain worship. The official history states the Chusha's deity is Ame-no-yagokoro-omoikane-no-mikoto, describing him as the god who originated the Iwato Kagura (sacred dance) during the Heavenly Rock Cave event. Here, Omoikane is not simply a smart god, but the inventor of rituals including performing arts. The Iwato Kagura belongs not only to Uzume who danced it, but also to the wisdom of Omoikane who constructed that setting. The Chusha's faith in academic success and business prosperity can be read as a faith in the power to synergize multiple conditions, beyond the simple wish that wisdom works well for exams or commerce. Yagokoro-omoikane-no-mikoto at Chichibu Shrine provides further political and regional context. The official page identifies this god as the ancestral god of politics, scholarship, industry, and good fortune, marking Chichibu-hiko-no-mikoto's enshrinement of his ancestral god as the origin of the shrine. The combination of politics, scholarship, and industry is very close to Omoikane's essence. Politics is the intellect to position people, scholarship is the intellect to establish logic, and industry is the intellect to actualize materials and techniques. The god who combined mirrors, jewels, iron, divination, and personnel allocation at the Heavenly Rock Cave being worshipped as the ancestral god of these three domains in later eras shows a perfect alignment between his mythological deeds and his divine virtues in faith. Reducing Omoikane to a light metaphor like "brain trust" obscures the gravity of the myth. He is a god who, when darkness covered the world, did not fight the darkness itself, but designed a space so the world could regain its brightness on its own. Amaterasu, Uzume, Tajikarao, the mirror maker, the jewel maker, norito, divination, and the sakaki tree—only when all of these are aligned does the rock cave open. Omoikane's power is not individual cleverness, but the power to weave multiple forces into a single restoration. What is needed in a deadlocked situation is neither shouting nor destruction, but the intellect to find the sequence. Omoikane is the god of that quiet sequence.

Ame-no-koyane, who recites norito before the rock cave, is the god in charge of the "voice" in the Heavenly Rock Cave myth. When Amaterasu-Omikami hid in the cave and the gods gathered at Ame-no-Yasukawara, Omoikane's plan could not succeed with just mirrors and jewels. In the Kojiki, Ame-no-koyane and Futodama-no-mikoto were summoned, prepared divination using the shoulder bone of a stag from Mount Amanokagu and Hahaka wood, and after hanging jewels, a mirror, and cloth on a sacred sakaki tree, Futodama held the gohei while Ame-no-koyane fervently recited the Futonoritogoto. Here lies the essence of this god. Through norito, Ame-no-koyane transforms the items prepared by the gods into acts performed before the divine. The scene at the Heavenly Rock Cave is often told with a focus on Ame-no-uzume's dance and Ame-no-tajikarao's strength. However, before the dance and the strength, the space is prepared as a ritual. The deer bone divination is a method to ask divine will, the mirror, jewels, and cloth are sacred signs, and the sakaki tree is the medium upon which they are hung. When Kokugakuin University's artifact commentary reads the myth as an origin tale of ancient rituals, Ame-no-koyane is at its center, taking the role of establishing the ritual as "words." Norito is not an explanation. It is a vocal technology that arranges the state of the world towards the divine. The contrast with Futodama is also important. Futodama holds the gohei, while Ame-no-koyane recites the norito. The ritual is first completed when what is held in the hand is combined with the words spoken from the mouth. With objects alone, it remains a silent offering; with words alone, it lacks form. Ame-no-koyane's norito binds Futodama's gohei, Ishikoridome's mirror, Tamanoya's jewels, Uzume's dance, and Tajikarao's hiding into a single space. He is not a god who performs conspicuous actions, but a god who unifies the meaning of the space. Kokugakuin University annotations note that in the Descent of the Heavenly Grandson, Ame-no-koyane is recorded as the ancestor of the Nakatomi muraji, descending as one of the Itsutomonoo accompanying Ninigi-no-mikoto. This is highly significant. The god who recited norito at the Heavenly Rock Cave becomes the ancestral god of the Nakatomi clan on earth, bearing the origin of the priestly function. Because the Nakatomi clan later connects to the Fujiwara clan, Ame-no-koyane is not merely a supporting character in an old myth, but a divine figure deeply involved with ancient state rituals and words, and further with the tutelary faith of aristocratic society. Ame-no-koyane at Kasuga Taisha conveys this lineage in its most visible form. The official history states that in the second year of Jingo-Keiun (768), a main sanctuary was built at the foot of Mount Mikasa for Takemikazuchi, Futsunushi, Ame-no-koyane, and Himegami. Alongside the martial gods of Kashima and Katori, Ame-no-koyane and Himegami constitute the Kasuga deities. Furthermore, Kasuga Taisha received reverence from emperors and retired emperors since ancient times, receiving many offerings as the tutelary shrine of the Fujiwara clan. Ame-no-koyane's norito expands into the prayers of the state and the clan at the Kasuga shrine. The power of Ame-no-koyane cannot be taken lightly as simply a "god of words." In myth, words create the space, invoke divine will, determine the meaning of objects, and support the order of the community. To bring Amaterasu out of the rock cave, not just a commotion but the legitimacy of a ritual was required. Norito is an utterance to "re-establish order" in a world sunken in darkness. Ame-no-koyane is the god responsible for that utterance, changing the direction of the world through voice. Seen in a modern light, Ame-no-koyane resonates deeply with domains where words build trust in a space, such as writing, oaths, prayers, hosting, legal affairs, ceremony design, and research presentations. Not raising one's voice, but arranging one's words. Not shouting a passing thought, but stating it in the correct order. Ame-no-koyane, who bundled the gods' powers into a ritual before the Heavenly Rock Cave, is a god who reminds us of the gravity of presenting words before the divine, especially in an age where words tend to be taken lightly. Moreover, Ame-no-koyane's mythological strength also lies in the fact that norito is not "personal words" but "words of the community." The norito recited before the Heavenly Rock Cave is not the emotional expression of the single deity Ame-no-koyane. It is a voice that bears all the ritual implements, divination, dance, laughter, and strength prepared by the myriads of gods, presenting the consensus of the gods to Amaterasu-Omikami. That is precisely why those words represent the space and correct the space. His later development as the ancestral god of the Nakatomi clan is also connected to this character of "speaking before the divine on behalf of the community." Ame-no-koyane is the god who elevates words from personal talent to the public nature of ritual.

Yamatohime appears as the mitsueshiro who guided Amaterasu Omikami to Ise. A mitsueshiro is not a vessel that controls the divine, but a being that serves the divine will and receives its destination in the human world. Her journey is not an escape far from the Yamato court. It is a tour to search for where the great goddess should be enshrined, to read the physiognomy of the land, to cross through provinces, and to find the center where the deity can settle in peace. In the official history of the Jingu Administration, Yamatohime left Yamato, passed through Iga, Omi, and Mino, and entered Ise Province. Ise, the endpoint of her journey, is not a mere destination. It was chosen as a land capable of quietly receiving the divine authority of Amaterasu Omikami, where clear water descends from the mountains to form the Isuzu River flowing to the sea, where the ocean opens to Tokoyo, and where the forests envelop the shrine. The expression "the upper reaches of the Isuzu River" found in the history of the Naiku perfectly illustrates Yamatohime's power. She is not a hero who calls back the light, but a deity who searches for a place where the light can remain without becoming muddied. Therefore, Yamatohime's spiritual power resides in "selection" and "order." Dividing the sacred realm from the secular world, maintaining purification and abstinence, and ensuring the rules of offerings and festival days are not disrupted. The Jingu Administration explains that after creating Kotai Jingu, Yamatohime established the systems of rituals and purification, building the foundation of the shrine. There is a different kind of tension here from the sudden bizarre occurrences often found in yokai tales. Unseen things become unruly if not welcomed correctly. Sacred things exhaust people if placed in the wrong location. Yamatohime knows that boundary and measures the distance between the divine and humans. Her presence manifests not as a loud oracle, but as a stillness that makes one stop at a fork in the road. The sound of water suddenly becoming clear, the wind changing at the entrance of a forest, words becoming sparse before an old shrine ground. To those who do not misread such small signs, Yamatohime indicates the next step. Conversely, to those who rush to conclusions, who try to paint over sacred sites with their own desires, or who disregard purification as a troublesome formality, the road will feel long, as if wandering in circles. Her protection is not in speed, but in correct anchoring. When understanding Yamatohime, it is best not to separate the three roles: the priestess who hears oracles, the traveling imperial princess, and the institutionalizer who creates the shrine system. The enumeration of her historical touring sites shows that she is not a deity of a single point, but a being who sanctifies the road itself. A road can be a symbol of being lost, but for Yamatohime, it is a process of discernment. The lands she passed through were not failed places. They were necessary memories to confirm the conditions for welcoming the deity one by one, heading toward the conclusion called Ise. Therefore, her story is better suited to the repetition of stopping, purifying, and walking again, rather than flashy moments of victory. For those who pray, Yamatohime is less a "deity who grants wishes" and more a "deity who teaches where wishes should be placed." When one wishes to rebuild the foundations of work, home, relationships, or study, she does not bring sudden change, but guides people toward preparing the environment, restoring order, and washing away unnecessary impurities. Before asking what to seek before the deity, she makes you question with what state of mind and body you stand before the deity. That strictness is also Yamatohime's gentleness. The Yamatohime-gu in Kusube-cho, Ise City, rests quietly in the forest of Mount Kurata, midway along the Miyuki Road connecting the Naiku and Geku. Although established as a Betsugu (auxiliary shrine) in the Taisho era as a new shrine, the deity enshrined there touches the oldest layers of the Ise faith. This overlapping of old and new befits Yamatohime's figure. She is not a legend closed in the past, but a memory that exists to continuously renew the places where deities are enshrined. The deity who established the shrine at the end of her journey still quietly asks in today's noisy world, "Where should the heart be calmed?" The time spent listening closely to that question itself becomes a pilgrimage to Yamatohime.

The Peculiarity of Japanese Mythology: Sun God = Female. While the base description touched on the primary myths of Amaterasu-Omikami, this detailed explanation delves into the comparative religious peculiarity of Japanese mythology in making the sun god female. Sun deities in ancient world mythologies—such as Greece's Apollo, Egypt's Ra, India's Surya, Inca's Inti, and Babylonia's Shamash—are predominantly male. On the other hand, female sun deities like Japan's Amaterasu, Norse's Sól, Baltic's Saulė, and some in Eastern Europe are relatively rare. In post-war Japanese mythological studies, scholars like Takeshi Matsumae proposed the male deity theory, stating that "the archetype of Amaterasu was various male sun gods (Amateru deities) who were later feminized," which became a central controversy. If we adopt this theory, the feminization of the sun god can be read as a unique deification process that advanced within the kingship, religion, and agricultural rituals of ancient Japan. The "Hiding in the Rock Cave" Tale ── Comparative Religion of Sun Disappearance Myths. The "Hiding in the Rock Cave" tale, where Amaterasu-Omikami hides in a cave and plunges the world into darkness, is a prime example of "sun disappearance and rebirth" in world mythology. Myths recounting the disappearance and rebirth of the sun—such as the Aten faith of ancient Egypt, Surtr in Norse myth, the Hittite sun god disappearance myth, and the Baltic sun god rebirth myths—are widely distributed as religious responses to the winter solstice, solar eclipses, and agricultural cycles in ancient farming societies. Amaterasu's seclusion is interpreted as the origin myth of Shinto kagura and ritual ceremonies, where "ritual tools like Ame-no-Uzume's kagura dance, the Yata mirror, jewels, evergreen trees, and the eternal bird (announcing the eternal dawn)" summon the sun god from the cave. As the root myth of religious rituals like the ancient Japanese winter solstice festival, Niiname-no-Matsuri, and Kanname-no-Matsuri, it holds cosmological significance far beyond a simple heroic tale. The Three Sacred Treasures ── The Unity of Kingship and Religion. The Three Sacred Treasures (the Yata mirror, Yasakani jewel, and Kusanagi sword) that Amaterasu-Omikami bestowed upon Ninigi during the heavenly descent symbolize the unity of kingship, religion, and mythology in ancient Japan. The Yata mirror embodies sunlight and Amaterasu's spirit; the jewel is a symbol of spiritual power and prayer in ancient Japanese religion; and the Kusanagi sword is a symbol of martial power and rule obtained through Susanoo's slaying of the Eight-Headed Serpent. The Three Sacred Treasures became the core of ancient imperial enthronement rituals and continue to function as the central apparatus of imperial succession ceremonies to this day. They are devices embodying the unique continuity of myth and politics in ancient Japan, where mythological narratives exert a sustained influence on modern political systems and state rituals. Ise Jingu and the Shikinen Sengu ── Two Thousand Years of Succession. The Inner Shrine of Ise Jingu (Kotaijingu) is the sacred site enshrining Amaterasu-Omikami from ancient times to the present. Through the "Shikinen Sengu" (the ritual of completely rebuilding the shrine buildings every 20 years), which began in the 4th year of Empress Jito (690 CE), ancient architectural techniques, rituals, and Shinto culture have been passed down for over 1,300 years. This is a unique philosophy of succession that "embodies eternity through newness"—realizing an "eternity as constant rebirth" through periodic wooden reconstruction, in contrast to the "unchanging eternity" of ancient stone temples. The Shikinen Sengu continues in the 21st century, with the 62nd iteration conducted in 2013. It is a rare phenomenon in world religious history that embodies the essential views of time, eternity, and renewal in ancient Shinto. The Imperial Lineage and the Basis of Ancient State Legitimacy. As the ancestral deity of the ancient imperial lineage, Amaterasu-Omikami has been at the core of the basis of legitimacy for the Japanese state from ancient times to the present. The genealogy from Emperor Jimmu to successive emperors to the modern emperor was established through five generations from Amaterasu, functioning as an apparatus to guarantee the continuity between ancient myth and the ancient state. This is a prime example of establishing legitimacy through a founding myth of an ancient state, alongside China's Mandate of Heaven, Korea's Dangun myth, Rome's Aeneas myth, and Britain's Brutus myth. She has a complex religious and political history, having been emphasized and politically utilized as the core of State Shinto in pre-war Japan, and undergoing a history of re-evaluation and depoliticization under the post-war system of separation of church and state and popular sovereignty. Ise Shinto, Ryobu Shinto, and Yoshida Shinto ── History of Medieval Shinto Thought. In medieval Japan, faith in Amaterasu-Omikami gave rise to multiple ideological systems such as Ise Shinto, Ryobu Shinto, Yoshida Shinto, and Suika Shinto. Ise Shinto (Kamakura-Muromachi periods) was formed by Ise priesthood lineages like the Watarai and Arakida families, producing Shinto scriptures like the "Shinto Gobusho." Ryobu Shinto (Kamakura period) was a syncretism with Shingon Esoteric Buddhism, centered on the "Honji Suijaku" theory that identified Amaterasu with Mahavairocana (Dainichi Nyorai). Yoshida Shinto (Muromachi period) was a unique system formed by Kanetomo Yoshida (1435-1511), advocating "Yuiitsu Shinto," which positioned Shinto above Buddhism and Confucianism. Suika Shinto (Edo period) was a system integrating Confucianism, Neo-Confucianism, and Shinto by Ansai Yamazaki (1618-1682), emphasizing Shinto ethics centered on Amaterasu. These medieval and early modern Shinto thoughts evolved around Amaterasu-Omikami as their central axis, playing a decisive role in the formation of Japan's indigenous religious philosophy. Amaterasu-Omikami in the 21st Century ── From National Tutelary Deity to Individual Spirituality. Under the post-war constitutional system of separation of religion and state and popular sovereignty, Amaterasu-Omikami has been redefined from a political status as the "core of pre-war State Shinto" to a religious status as the "tutelary deity of the entire nation and the spiritual pillar of individuals." With over 8 million annual visitors to Ise Jingu, the nationwide distribution of Jingu Taima (amulets) centered on Ise Jingu, and the organizational structure of Shinto groups and the Association of Shinto Shrines, faith in Amaterasu remains at the foundation of Japanese daily religious life in the 21st century. At the same time, she has become a modern icon repeatedly reimagined in subcultures, games, and manga, making this a rare case where ancient myth and the spiritual culture of modern Japanese people maintain continuity across two millennia. Beyond merely a deity appearing in myths, she is a presence that holds sustained meaning as a core symbol running through the entirety of Japanese culture.
