in a station of the metro
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 several months ago moved on to behavior that is apparently encouraged.
The above images are 'repurposed' from a campaign poster that urges passengers be considerate of their fellow travelers and shut off their phones when standing near the 'priority seats'. I'm not sure why the silent/vibrate mode they encourage elsewhere in carriages isn't good enough when standing near elderly, pregnant and disabled people, but ours is not to reason why.
