Kokoro, Omoi and Kotoba in the Aesthetic Matrix of Ushin
In the framework of classical Japanese aesthetics, as elucidated by Izutsu, the concepts of kokoro, omoi, and kotoba form a triadic structure foundational to the emergence of aesthetic value. This structure is central to understanding the aesthetic ideal of ushin, as articulated by Fujiwara no Teika. Izutsu’s theory of beauty treats these elements not as isolated psychological or linguistic units, but as structurally interdependent moments within a process that generates aesthetic value. The relationship among these three -kokoro as the ground, omoi as inner language, and kotoba as external language- constitutes the matrix in which ushin arises as a specific quality of poetic expression.
Izutsu characterizes kokoro as the ultimate origin of poetic creation. It is the foundational stratum, undifferentiated and pre-linguistic, from which all aesthetic articulation begins. It is not yet reflective or linguistic, but is the source of all possible articulation. As the ground of all poetic activity, kokoro is a silent, still reservoir, the metaphysical core from which sensibility, affectivity, and perception issue. In the poetic context, kokoro is not a static essence but a dynamic potentiality, the existential source of all meaningful form.
In Izutsu’s analysis, kokoro is not an empirical faculty but the ontological basis of poetic consciousness. It is the field within which aesthetic movement begins, the field in which omoi arises. It contains no content in itself, yet it is the condition for content. In terms of structure, kokoro is the metaphysical locus in which the potential for articulation lies latent. It is the necessary ground for the possibility of aesthetic value.
Omoi refers to the first differentiation within kokoro. It is the emergence of an inward movement of feeling or thought. Izutsu defines omoi as inner language, not in the grammatical or syntactical sense, but as the inner structuring of meaning before articulation. Omoi is already semiotic, but it remains internal, non-phonetic, and non-actualized. It is the phase in which kokoro becomes self-referential, turning inward as affective or cognitive formation.
In the structure of poetic creation, omoi is the intentional movement that prepares kokoro for externalization. It carries emotional density and is charged with the depth of subjective experience, though still contained within the interior realm. According to Izutsu, omoi exists as the pre-verbal resonance of feeling, and is a necessary intermediary between the metaphysical ground and linguistic expression. It provides form to the otherwise formless kokoro.
Kotoba is the actualization of omoi in articulated linguistic form. It is the external language, the expressed word. Within Izutsu’s framework, kotoba is not a mere mechanical representation of omoi, but a structurally necessary stage in which inner content assumes objective form. In this phase, meaning becomes communicable and aesthetic judgment becomes possible.
Kotoba is constituted by the syntactic and phonetic structures of language, yet its aesthetic value depends on the depth of omoi it conveys. The poetic function of kotoba is not to denote but to evoke. The success of kotoba lies in its ability to transmit the movement of omoi, and through it, the silent presence of kokoro. Izutsu emphasizes that the function of language in Japanese poetics is not representational but disclosive. It reveals rather than defines.
Ushin is the aesthetic value that emerges from the dynamic interaction of kokoro, omoi, and kotoba. According to Fujiwara no Teika, ushin is the indispensable basis of all poetic beauty. It is not a style or mode, but a structural condition in which the poem is “with-kokoro” -infused with mind and inwardness. Izutsu identifies ushin as the synthesis in which the metaphysical ground (kokoro), the affective structuring (omoi), and the linguistic actualization (kotoba) converge.
Ushin is not reducible to any one of the three moments but arises only in their structural unity. If kokoro is absent, the poem lacks depth; if omoi is absent, the poem lacks emotional clarity; if kotoba is absent or misaligned, the poem lacks form and communicability. The aesthetic quality of ushin requires the full realization of each component in its proper relation to the others.
In Izutsu’s theoretical language, ushin is the field of actualized poetic being, in which language, mind, and ground are co-present. It is the ontological condition of aesthetic experience, the realized form of the poetic real.
The structural interrelation of kokoro, omoi, and kotoba forms the essential matrix of aesthetic production in the classical Japanese poetic tradition. As explicated by Izutsu, this triadic structure is not linear but concentric, with each element presupposing the others in a unified dynamic. The emergence of ushin as aesthetic value is the product of this structure, and it serves as the fundamental criterion for poetic excellence in the system articulated by Teika. Izutsu’s theory clarifies that Japanese aesthetics does not operate on a dichotomy between inner and outer, form and content, but on an integrated model in which metaphysical origin, inner structuring, and external expression are inseparably joined in the act of poetic creation.
