This study examines the visual and narrative transitions across three major ecological feature animations by Hayao Miyazaki—Nausicaä of the Valley of the Wind (1984), Princess Mononoke (1997), and The Boy and the Heron (2023)—in order to trace a long arc of transformation from landscapes of ruin toward emerging forms of multispecies coexistence. Although produced across nearly four decades, these films form a coherent developmental sequence in Miyazaki’s ecological imagination. Each film begins from a site of damage—post‑apocalyptic wastelands, industrial wounds, or the psychic debris of war—and gradually moves toward new modes of relationality between humans and the more‑than‑human world. The three works were selected because they share thematic continuity, increasing stylistic maturity, and a persistent reliance on hand‑drawn animation, which provides a material foundation for the ethical and aesthetic questions the films raise. Together, they can be read as a trilogy of environmental thought that charts a movement from devastation to renewal, from estrangement to kinship, and from anthropocentric narratives to a vision of shared planetary life. The central question of this research concerns the role of visual form in shaping ecological meaning. Rather than treating animation as a neutral container for narrative themes, the study argues that line, color, texture, and composition actively participate in producing ethical and ontological insight. In Miyazaki’s work, the material qualities of hand‑drawn animation—its trembling lines, layered pigments, and organic spatial arrangements—do not merely illustrate ecological ideas; they enact them. The films construct a visual language in which the boundaries between human and nonhuman, culture and nature, and subject and environment become porous. This visual language is not decorative but conceptual: it generates ways of seeing and feeling that invite viewers to reconsider their relationship with the living world. The research adopts a qualitative, descriptive‑formal methodology grounded in frame‑by‑frame analysis. Key scenes from each film were examined through close attention to line quality, color palette transitions, compositional balance, depth of field, and the spatial relationships between bodies—human, animal, vegetal, and elemental. Supplementary materials such as artbooks, production sketches, and interviews with Miyazaki and his collaborators were used to contextualize the visual decisions embedded in the films. This approach allows the study to move beyond thematic interpretation and toward an integrated understanding of how visual form, narrative structure, and ecological imagination interact. Across the three films, a recurring three‑stage narrative pattern emerges. The first stage, which may be called attunement, involves the protagonist’s initial encounter with the nonhuman world. This encounter is often marked by fear, uncertainty, or estrangement, yet it gradually becomes a form of listening—an openness to rhythms, textures, and presences that exceed human understanding. In Nausicaä, this stage appears in the protagonist’s tactile exploration of the toxic jungle, where she touches spores, observes insects, and breathes in the altered atmosphere with cautious curiosity. In Princess Mononoke, attunement takes the form of the young warrior’s first encounters with forest spirits and wounded animals, where he must learn to read signs of suffering and anger inscribed in their bodies. In The Boy and the Heron, attunement unfolds through the protagonist’s entry into a liminal world shaped by grief, memory, and ecological echoes, where familiar categories of life and death blur. The second stage, empathy, involves a deepening recognition of the agency, vulnerability, and emotional life of nonhuman beings. This stage is not sentimental but ethical: it requires acknowledging the wounds inflicted by human actions and accepting responsibility for the consequences.



In Nausicaä, empathy is expressed through the protagonist’s efforts to understand the giant insects not as monsters but as guardians of a damaged ecosystem. In Princess Mononoke, empathy emerges in the protagonist’s attempts to mediate between humans and forest gods, recognizing the legitimacy of both their needs and their grievances. In The Boy and the Heron, empathy takes on a more introspective dimension, as the protagonist confronts creatures that mirror his own internal fractures and unresolved losses.



The third stage, kin‑making, marks the emergence of new forms of relationality that transcend species boundaries. Kin‑making is enacted through gestures of cooperation, play, sacrifice, and co‑creation. It is not a return to an idealized harmony but a practice of living with difference and damage. In Nausicaä, kin‑making culminates in the protagonist’s willingness to risk her life to protect the insects and restore balance to the poisoned world. In Princess Mononoke, it appears in the fragile, hard‑won coexistence between humans and the forest, where neither side triumphs but both learn to rebuild. In The Boy and the Heron, kin‑making becomes a personal and existential commitment to reinhabiting the imperfect real world rather than escaping into fantasy. These narrative stages are mirrored by visual transformations. The trembling line, a hallmark of hand‑drawn animation, plays a crucial role in conveying vitality and vulnerability. Unlike the clean, uniform lines of digital animation, the hand‑drawn line carries traces of the animator’s body—pressure, hesitation, rhythm. This material presence imbues characters and landscapes with a sense of aliveness that is inseparable from their fragility. In scenes of ecological tension, the line becomes more unstable, suggesting environments on the verge of collapse. In moments of renewal, the line stabilizes or flows more freely, signaling the possibility of regeneration. Color transitions also function as narrative and ethical indicators. Each film begins with palettes dominated by cold, desaturated, or toxic hues—grays, blues, sickly yellows—that evoke contamination, decay, or emotional numbness. As the protagonists move through the stages of attunement, empathy, and kin‑making, the palette gradually shifts toward warmer, more saturated tones—greens, golds, and earth colors—that signal ecological and emotional transformation. These shifts are not merely symbolic; they shape the viewer’s sensory experience of the world on screen, guiding perception toward states of openness, care, and connection. Composition further reinforces the films’ ecological vision. Miyazaki frequently employs layered depth, asymmetrical balance, and diagonal movement to create dynamic relationships between bodies and environments. Human figures are rarely centered or isolated; instead, they are embedded within complex spatial arrangements that emphasize interdependence. In many scenes, the boundaries between foreground and background dissolve, and human and nonhuman bodies overlap or interpenetrate. This compositional strategy challenges anthropocentric visual hierarchies and invites viewers to perceive the world as a network of relations rather than a stage for human action. The study situates these visual and narrative patterns within broader conceptual frameworks concerning multispecies coexistence, ecological ethics, and the role of imagination in shaping collective futures. Rather than relying on direct theoretical citations, the analysis draws on ideas that emphasize the importance of staying with ecological trouble, cultivating new forms of kinship, and envisioning futures grounded in mutual care rather than domination. These ideas resonate strongly with Miyazaki’s films, which consistently refuse simplistic resolutions or utopian fantasies. Instead, they present the Symbiocene not as a distant ideal but as an emergent possibility that must be practiced in the midst of irreversible damage. Across the trilogy, the movement from ruin to renewal is neither linear nor guaranteed.

Each film acknowledges the persistence of violence, grief, and loss. Yet each also insists that new forms of life can emerge from the cracks of damaged worlds. In Nausicaä, hope is preventive and cautious, grounded in the recognition that toxic environments can be healed only through patience and humility. In Princess Mononoke, hope is contested and painful, forged through conflict and compromise. In The Boy and the Heron, hope becomes deeply personal, rooted not in escaping the world but in choosing to inhabit it with care. The contribution of this research lies in demonstrating that ecological meaning in Miyazaki’s work is inseparable from the material techniques of hand‑drawn animation. The trembling line, shifting palette, and organic composition are not aesthetic flourishes but ethical gestures. They shape how viewers perceive the world and their place within it. By integrating close formal analysis with ecological and philosophical reflection, the study offers a model for understanding how visual form can function as a mode of ethical and ontological inquiry. This model has implications not only for animation studies but also for environmental media theory, visual ecology, and the broader project of cultivating ecological imagination in the twenty‑first century.
