"i have a baby in my belly"

Japan is an ageing society. the government has understood the problem and introduced some measures or plans for measures that should encourage the young to get children. (of course not touching the major cause - something anyone who has been in touch with the japanese education system would immediately identify: financial matters) But small measures sum up, hopefully.
however, recently i was lucky to identify the first installment of a series of measures on the train, where else. (I am not talking about the newly errected gates on the platforms of marunouchi line to avoid young drunkards falling in front of the train before having given birth to a new japanese... although very interesting by itself)
i am talking about the priority seats. one should know that in all trains at the end of each car there are priority seats, distinguished by different use of color and a big sticker indicating that this is for elderly, injured or people involved with small children outside or inside their bellys.
there is a big problem with commuting masses and drunkards (see above) on the train, especially at night. these people are tired and want to sit down. in order to not loose your seat if it is marked priority there are at least two different ways how to behave. tested succesfully by myself. first method would be to fall asleep immediately. best method in my opinion. works even better with newspaper in front of the forehead or earphones blocking accoustic signals like those of caughing elderly, etc.. than there is the shirankao. it translates to "have-no-clue-face". basically it is about the right questions to ask yourself, i mean how are we supposed to differentiate an elderly from the average person in an ageing society? same goes for pregnant women in a society changing food preferences from fish to meat?
but wait, here is where the government sees a chance of improvement. pregnant women should wear a sticker just like the one on the picture above, so there is no doubt about it anymore.


well...

i see two problems here. first, will any japanese, i repeat, j a p a n e s e woman, renowned for their modesty, wear this sticker, imposing their state upon other commuters?
secondly, do work-all-day commuters even care after they have sunken into their hard earned seat? only time will show.
