In spanking clean Tokyo, graffiti sprayers do not have an easy life. There are just not enough places to spray. Abandoned estates and run down industrial sites are almost non-existent. The sakuragi-cho railway station on the outskirts of the city offers a welcome opportunity. It has got a 2 mile railway bridge, where graffiti artists from all over Japan leave their tags and designs. but even here they are not safe from arrest by stern law enforcers
