With the Setsuna concept, Toyota is expressing the notion that, as a family accrues time and experiences together with their car, lovingly caring for it and passing it on to the next generation, that car will acquire a new type of value that only the members of that family can appreciate.
However, the Setsuna is not a piece of furniture – it is a fully functioning car, although not road-legal. For this reason, different types of wood were chosen for specific parts of the vehicle – including Japanese cedar, with its vivid grain and flexibility for the exterior panels; strong and rigid Japanese birch for the frame; hard-wearing Japanese zelkova for the seats; and smooth-textured castor aralia for the seats.
The concept of an 'accumulation of moments' is expressed through the vehicle’s radial, circular emblem. While giving the impression of a blooming flower, the design also evokes the appearance of a clock that shows each individual moment.
