The pocket-sized detector called Kunkun Body which looks like a tape recorder, connects by bluetooth to a smartphone app that divulges the potentially ominous results in a suitably discreet manner, reports the Guardian.
Konica Minolta, the firm previously best known for producing cameras and printers, believes there is a market for the odour checker in Japan because people are "particularly sensitive to smell".
There is even a word in Japanese for the behaviour of office workers who annoy others with their noxious aromas - sumehara, or "smell harassment".
Daisuke Koda, who is the incubation lead at Konica Minolta Japan's business innovation centre, told the Guardian that the idea arose after a discussion he had with several male colleagues, all aged about 40, two years ago.
The device is priced at 30,000 yen ($265).
It's not the first device aimed at addressing smell-related worries in Japan. Last year, Sony released a portable aroma diffuser called Aromastic. Owners of the device, dubbed an "aromatic Walkman", can select which scent they want emitted in their vicinity.
