3/23~4/6 Campaign: Find the #Trafficking Awareness Poster at stations of Tokyo Metro (and other trains)

Find the human trafficking awareness posters at Tokyo Metro Stations (Fri. March 23-Thur.29) and other  railway stations, and post the photo on your facebook wall, twitter, etc to raise awareness of human trafficking problems in Japan! (Hashtag:#人身取引ポスター or #Trafficking Awareness Poster)

The poster is written in Japanese, but there is the English version for the smaller sized flyer.

We only know that Tokyo Metro will post the poster 3/23 thru 29 in some of its stations. We know that JR East and other private railway companies (Tobu, Seibu, Keisei, Keio, Odakyu, Tokyu, Keikyu, Sotetsu, Meitetsu, Kintetsu, Nankai, Keihan, and Nishitetsu) are asked to post the poster but don’t know when, where, and how it will be done.
