Presenting the RiN Concept at the 2007 Tokyo Motor Show, Toyota stated "the RiN focuses on “increased comfort” and “serene, healthy living”. Through their relationship to the vehicle, drivers are encouraged to re-evaluate themselves and, furthermore, to turn their attention to society and nature, producing a healthy rhythm for both mind and body."

The exterior body has a box-shape with sliding doors with lower windows which allow passengers to have a view of the surrounding environment at ground level.

The headlights feature light distribution control that take into consideration pedestrians and vehicles coming in the opposite direction.

The design language for both the exterior and the interior makes use of the motif of the deep-rooted and tall-growing Yakusugi tree (a variety of Japanese cypress), in order to express “harmony with nature” and “healthy mind and body”.

The interior is characterized by a contrasting deep-green and beige color scheme that "evokes a healthy mental and physical feeling."

Among the features of the cabin are the heated seats, designed to help maintaining a good back posture, an oxygen-level conditioner and pinpoint humidifier and green glass surfaces, that reduce infiltration of ultraviolet and infrared light and makes the surroundings seem brighter and clearer to increase cabin comfort.

The meter cluster of the “mood-training” steering control conveys "images aligned with the driver’s psychological state."
