Some Japanese men will be smelling of roses just in time for Valentine’s day. The Otoko Kaoru (good-smelling man) Fragrant Shirt was released for sale in Japan just last month and is attracting a lot of attention from retailers who have snapped up the first run of these sweetly smelling garments. A tie-in with Otoko Kaoru chewing gum, the collar of the shirt releases the same rose and menthol fragrance as the gum when rubbed against the skin.

Rose-scented micro-capsules are embedded in the shirt’s collar and if they’re rubbed or put under pressure they explode, releasing a liquid that evaporates into the air around. The scent is designed to be subtle rather than overpowering and can only be smelled when the shirt is worn. It will also gradually lose its potency over time and manufacturer’s claim its good for around 10 washes, after which the smell fades completely.
