Arpa’s first book gathers years of research into a single object constructed as an archival report, blending fictional texts with visual study. Across multiple covers, inserts and folded documents, the book traces how scent, image and narrative inform and shape one another.

Rooted in Japanese Metabolist architectural thought, the project draws from ideas of growth, modularity and impermanence, where structures transform and adapt like living bodies. This conceptual framework became the foundation for a fiction by writer @theocasciani, following the birth of a humanoid lifeform emerging from an iris seed, shaped by vegetal memory and digital data.

Carrying this narrative further, the visual system developed by @adulte_adulte gives the fictional being a body of its own. Through layout, forms and colour, the studio shaped humanoid silhouettes for each fragrance, translating the story into a chromatic and material language.

The photographs by @tomdepeyret, mostly taken in Japan where Arpa is consolidating its presence, trace a visual journey through the spaces and buildings that informed the development of each fragrance in Sequence 2 and echo the principles of Metabolist architecture.

Together, these elements form Arpa Synesthesia, an experimental atlas of perception. The book articulates the connections between smell, vision, matter and imagination, offering a new way to read Arpa’s perfumes through architecture, storytelling and sensory research.
