Young, fresh faced and ripped, the nikushokukei danshi is the dish du jour for the modern Japanese woman, according to some media outlets.

The word refers to beefy guys who do a physically demanding job and is a reversal of sōshokukei danshi (grass-eating men), a term popularized in 2008 that describes the new breed of gentle, passive men emerging in Japanese society. While sōshokukei reflected an emerging social reality, nikushokukei reveals an a female fantasy that is in part a reaction against the grass-eating males.

It all got started in August when “Sagawa Danshi,” a photo book featuring 51 cute young Sagawa Express delivery guys was published. The book was a surprise hit, going into its second print run in a matter of only two weeks. Excite News reported that a meet-and-greet session last month was attended by more than 100 fans, both male and female, who came to take snaps of their favorite pin-ups.
