The One-of-a-Kind Aroma Spray That Recreates the 'Smell of Space'

The scent of outer space is described as a 'tangy, burnt-like aroma' detected when astronauts return from spacewalks and volatile compounds from their suits evaporate inside the space station. This scent, famously described by astronaut Naoko Yamazaki as 'like raspberry,' has been scientifically recreated by Promotool’s team led by Takeshi Watanabe, a perfumer recognized as one of Japan’s leading experts, using data including ethyl formate and other chemical components.

'Cosmos Scent®' was first adopted at the 'Universe Nanchara Kotetsu-kun' booth during the 2024 Tokyo Toy Show, and has since been featured at space-themed facilities and events such as 'TeNQ' at Tokyo Dome City and 'Chikyuu no Niwa' by AEON Fantasy. Responding to long-standing public demand, the company has now decided to launch it as an aromatherapy spray.
