"URABON" is the pornography photograph collection
for adults which is published illegally in Japan.
This site is so-called "Adult site" which obviously contains plain expression and content sexual intended for adult.
Please leave at once when is forbidden by the restriction of the group to which you belong etc. when you are 21 years old or less.
Other "URABON" should also come to hand!!
Since it is the site in Japan, although it is naturally Japanese, probably it can use easily.
