This little bit of information caught me off guard:
Just this year, Japan lifted its general ban on domestic political campaigning activities conducted online. It is now legal for Japanese political candidates to set up websites and advertise their platforms through social networking services. (That's right--
it used to be a no-no in this country.)
Now, with this ban lifted, the Ministry of Internal Affairs and Communications has identified as a potential issue the activities of minors--that's anyone under the age of 20 here--in relation to political campaign efforts.
To try to nip any such activity in the bud, the
ministry has issued a blanket statement targeting minors, reminding them that they face potential fines of up to 300,000 yen ($3000) and up to a year of jail time should they express public support for a campaign during their online activities.
