And what if you have the 3G version? Well, things might get embarrassing.
Docomo is the PS Vita's official 3G carrier in Japan, offering two plans: a prepaid 20 hour plan and a 100 hour plan.
To protect underage gamers, the PS Vita's default settings do not allow access to "unsuitable sites" through the 3G Vita's Prepaid Folder.
According to an official NTT Docomo release, those who wish to have unrestricted access must take their Docomo UIM card as well as photo identification (such as a driver's license) to their local Docomo shop.
Those under the age of 20, must have a signed letter of consent from a legal guardian.
It would be possible to access adult sites through wifi. Since wifi is scant in so much of the country, that is easier said than done.
Japanese netizens pointed out that this could lead to some awkward exchanges between game otaku and Docomo female clerks as well as pleading between middle schoolers and their moms.
Get the wifi version, people! Because the only real screwing you're going to see is the bill from Docomo.
