The brand name itself, TAJFUNY, is already associable with the Japan-ness. So the creative team came up with the marine pattern of Seigaiha-mon and Fugaku Sanjurokkei by Katsushika Hokusai to transform the waves into the defining image of the store. Alongside the waves, the logotype features the Futura type, which adds a reserved impression even in the minimal environment.
The brand centres around the blue coloring with such traditional colors as ultramarine blue and indigo blue — both frequently used in a Japanese style painting. All together, these components are to be explored in the packaging, book cover design and other branding tools. I guess you will particularly love the book covers, which are an apogee of Japanese aesthetics with the minor folklore details to reflect the fascination of the reader and the mastership of the design team.
