Tokyo Metro Manners: Korean Girl Bands
Click comic to ENLARGE.
The Tokyo Metro has been running a 'manners campaign' for several years, and each month publishes a new poster in stations. Over the months, the campaign has pretty much covered every bit of proscribed activity (don't throw up on your fellow passengers, don't practice your golf swing on the platform with a wet umbrella, etc.) imaginable, and six or so months ago moved on to behavior that is apparently encouraged.
The above images are 'repurposed' from a campaign poster that urges passengers to be considerate of their fellow travelers by not blocking the exit doors. Besides clogged train doorways, middle-aged and elderly Japanese (seemingly the beneficiaries of most of the manners posters) are also facing the inexorable decline of their culture, most recently evidenced by the rising popularity of Korean girl bands at the expense of Japanese ones.
And the vegetarianism reference, of course, is to Japan's "herbivore men".
Yes, it's a difficult time in Japan.
Great thanks to @JM_Leee for the Korean translations and checking!
