Kaguya-hime and Buan: The Hidden Maidens of the Moon

Kaguya-hime (かぐや姫), commonly translated as Princess Kaguya or the Shining Princess, is the central supernatural figure of the Japanese Taketori Monogatari (The Tale of the Bamboo Cutter), one of Japan's earliest surviving prose narratives. The story describes Kaguya as a mysterious maiden of celestial origin who is discovered as a tiny child inside a shining bamboo stalk. She grows with supernatural speed into an exceptionally beautiful young woman and eventually reveals that she belongs to the Moon and must return there.

A comparable figure can be found in descriptions of Buan, one of the many moon deities in Philippine mythology. the Moon, within the traditional religious beliefs of the ancient Tagalog peoples of the Philippines. Buan is associated with the Moon and is described in some ethnographic accounts as a dalaga, or maiden, including the expression Dalagang Nasa Buwan, meaning "Maiden in the Moon." She is also associated with the image of the Dalagang Binubukot, the secluded or hidden maiden.

Kaguya and Buan do not belong to the same mythology, and there is no established historical evidence that one tradition was derived from the other. Their resemblance is instead an example of a recurring mythological motif: the Moon represented as a beautiful, secluded, feminine supernatural being who remains separated from ordinary human society.

Kaguya-hime in Japanese Tradition

The story of Kaguya-hime is preserved in the Taketori Monogatari, generally regarded as one of the oldest works of Japanese prose literature. The narrative begins when an elderly bamboo cutter discovers an unusual stalk shining with light. Within it he finds a tiny girl.

He takes the child home, where she is raised by him and his wife. Her growth is extraordinary. Within a short period she becomes a young woman of remarkable beauty. Her supernatural nature is suggested not only by her unusual birth and rapid maturation but also by the mysterious circumstances surrounding her eventual return to the heavens.

As word of her beauty spreads, numerous aristocratic men seek to marry her. Kaguya refuses to accept an ordinary marriage and assigns her suitors impossible tasks, requiring them to obtain legendary objects. Their failures emphasize that Kaguya cannot be obtained through conventional human means.

The Emperor also becomes interested in her, but Kaguya remains emotionally and spiritually distant from the human world.

Eventually, Kaguya reveals that she is a being of the Moon. Her stay on Earth is temporary. When the appointed time arrives, celestial beings descend to retrieve her. Human attempts to prevent her departure are unsuccessful.

Kaguya is consequently returned to the Moon, leaving behind the people who had loved her.

The fundamental structure of the legend is therefore one of descent, concealment, revelation, and celestial return:

• Kaguya originates in the heavens.
• She is concealed within the earthly world.
• She assumes the appearance of a human maiden.
• Her extraordinary beauty attracts human attention.
• Her true identity remains inaccessible to humans.
• She ultimately returns to her celestial home.

The Moon in Kaguya's story consequently functions as more than a physical location. It represents her true homeland, a supernatural realm fundamentally separated from the human world.

Buan and the Tagalog Moon

In traditional Tagalog cosmology, the Moon was associated with Buan, a divine or supernatural lunar figure. The name is related to the Tagalog word buwan, meaning "moon," although terminology and descriptions of precolonial Tagalog religion vary among historical sources.

Some accounts characterize Buan as a maiden associated with the Moon. She appears in the conceptual form of the Dalagang Nasa Buwan, literally the "Maiden in the Moon."

This imagery is particularly significant because the maiden is not portrayed simply as an ordinary woman living in the heavens. She is secluded.

The related expression Dalagang Binubukot evokes the cultural practice of pagbubukot, in which a high-status maiden could be secluded and carefully protected from public view. The binukot therefore becomes an important cultural image for understanding the idea of a beautiful maiden who is kept hidden, protected, and inaccessible.

When applied metaphorically to the Moon, the image produces a striking cosmological conception: the Moon becomes the dwelling place of a hidden maiden.

The lunar maiden is visible to humanity, but she is never physically accessible. People can observe the Moon, address prayers or wishes toward it, and associate its cycles with earthly fortune, but the celestial maiden remains separated from human society.

Buan the Moon goddess Dalagang nasa Buwan is called Kulalaying by people of Laguna

The Motif of the Hidden Maiden

The strongest parallel between Kaguya and Buan is therefore not simply that both are associated with the Moon. It is the recurring mythological concept of the hidden maiden.

In both traditions, the supernatural woman possesses exceptional beauty while remaining outside ordinary social relationships.

Kaguya is physically present on Earth but is ultimately revealed to belong to another realm.

Buan is imagined as existing within the Moon itself, beyond the ordinary human world.

This produces a common symbolic structure:

beauty → seclusion → mystery → unattainability → celestial identity

The maiden's hidden nature is essential to her supernatural status. She is not a woman whose beauty is simply admired. Her beauty signifies that she belongs to a realm beyond ordinary human existence.

The Moon as a Female Figure

The personification of the Moon as androgynous and  feminine is widespread in world mythology, although cultures differ considerably in their interpretations of lunar gender and symbolism.

In the Kaguya tradition, the Moon is the homeland of a celestial people and of Kaguya herself. Her return to the Moon represents the restoration of her supernatural identity.

In the Tagalog ancient tradition, Buan provides a more direct personification: the Moon itself can be understood through the image of a divine maiden.

This creates two related but distinct models.

Kaguya represents the maiden of the Moon.

Buan represents the Moon as a maiden.

This distinction is important when comparing the two traditions. Kaguya is an individual supernatural princess whose celestial origin explains her connection with the Moon. Buan, by contrast, is directly associated with the lunar body and its divine identity.

Seclusion and the Binukot

The comparison with the binukot tradition is particularly significant when interpreting the image of Buan.

The binukot was a maiden who was secluded from ordinary society and carefully guarded. Such seclusion could signify status, purity, beauty, and social value.

This cultural concept provides an especially appropriate metaphor for a lunar maiden.

The Moon itself is visible but unreachable. Its light can be seen by everyone, while its celestial interior remains inaccessible. In mythological terms, the Moon therefore becomes an enormous cosmic chamber in which the maiden is hidden.

The image may be summarized as:

the village has its hidden maiden; the heavens have their Moon-maiden.

The comparison does not mean that Buan was literally a binukot in the historical social sense. Rather, the concept of the secluded maiden provides a useful cultural framework for understanding why the phrase Dalagang Binubukot can evoke the image of a mysterious lunar woman.

Kaguya and the Unattainable Woman

Kaguya's relationships with her suitors further reinforce this motif.

Her admirers attempt to obtain her through courtship, wealth, status, and heroic deeds. Yet none succeeds. Her supernatural demands expose the limitations of human power.

Kaguya therefore embodies the unattainable maiden.

Her beauty creates desire, but her celestial identity prevents possession.

This is one of the central tensions of the Taketori Monogatari: Kaguya lives among humans, but she cannot ultimately become part of human society.

Her eventual return to the Moon resolves the contradiction.

She was never truly a human bride.

She was a celestial maiden temporarily hidden among humans.

Buan and the Unreachable Maiden

The image of Buan similarly places the maiden beyond physical human possession.

The Moon can be admired, addressed, and associated with wishes, but it cannot be reached by ordinary people.

This gives the lunar maiden a paradoxical quality:

she is visible yet hidden; familiar yet distant; beautiful yet unattainable.

The Moon is perhaps the ideal celestial object for such a figure. Unlike distant stars, it appears close enough to invite human imagination. Yet its physical distance ensures that the imagined maiden remains permanently separated from humanity.

The lunar maiden therefore occupies a boundary between two realms:

Earth and Heaven.

Lunar Cycles and the Hidden Maiden

The changing appearance of the Moon also lends itself naturally to the imagery of concealment.

During the new Moon, the maiden is invisible.

As the crescent appears, she begins to reveal herself.

During the waxing Moon, more of her becomes visible.

At the full Moon, the celestial maiden appears in her complete radiance.

She then gradually withdraws again.

Through this interpretation, the phases of the Moon become a symbolic cycle of concealment and revelation.

The maiden is never permanently absent. Her disappearance is temporary, just as her appearance is temporary.

This cyclical quality distinguishes lunar mythology from myths of a single celestial descent. Kaguya's story is linear: she comes to Earth and eventually returns to the Moon. Buan, as the personified Moon, can instead be imagined as continually undergoing cycles of appearance and concealment.

The Shared Image of the Moon Maiden

The enduring similarity between the two traditions lies in their conception of femininity as something luminous, sacred, secluded, and beyond possession.

Kaguya is a woman from the Moon who temporarily becomes part of human society.

Buan is a lunar maiden whose celestial dwelling places her permanently beyond ordinary human society.

Both can consequently be understood through the archetypal image of the Moon Maiden: a supernatural woman whose beauty is inseparable from her distance.

Her long dark hair, pale or luminous appearance, and secluded existence belong especially well to later artistic representations of the lunar maiden. Such details should be distinguished from the earliest surviving textual descriptions, however; the familiar modern visual image of a fair-skinned, long-haired Moon Princess is partly the product of later artistic interpretation rather than a single fixed ancient description.

The Hidden Maiden as a Mythological Archetype

The comparison between Kaguya and Buan illustrates a broader mythological pattern.

Across cultures, supernatural women are frequently associated with thresholds: between Earth and Heaven, life and death, visibility and invisibility, desire and impossibility.

The Moon is itself a threshold symbol.

It belongs to the sky but influences the Earth. It disappears but returns. It appears to change while remaining the same celestial body. It illuminates darkness without becoming part of the human world.

The Moon Maiden expresses these same qualities in human form.

She is:

• hidden, because the divine cannot be completely known;
• beautiful, because the celestial is represented as extraordinary;
• secluded, because sacred things are kept apart from ordinary life;
• unattainable, because humans cannot possess the divine;
• cyclical, because the Moon continually disappears and returns;
• liminal, because she exists between the human and supernatural realms.

Kaguya-hime and Buan therefore represent two culturally distinct expressions of a remarkably similar mythological imagination.

One tradition tells of a princess who came from the Moon.

The other imagines a maiden who remains within the Moon.

In both, the Moon becomes not merely an object in the night sky, but a mysterious feminine realm a place where a beautiful maiden remains hidden from humanity, visible in her radiance but forever beyond human reach.
