Japanese Dreadlocks

This is a typical Tokyo subway scene....twenty-something Tokyonite with perfect dreadlocks and a record case for dj'ing under his arm, and a kimono-clad middle-aged woman standing in front of him. The juxtaposition from the older generation (men wearing the same black suit, drab expressions, working for the same Japanese company from the day you graduate until the day you die...from now on these men will be referred to as "salarymen") versus the younger generation (afros, dreadlocks, painted faces, fake tans, six-inch heals, no ambition, no desire to work, much less to work for a Japanese company...from now on they will be referred to as "NEETS" as in 'not in education, employment or training,' i think it's a term from the UK in the 1970s but now it's come to describe this whole generation of lost Japanese youth). I'm fascinated by the young people here, the way the dress, their tribal gangs. But I wonder if it's just superficial. I don't seen any kind of real rebellion going on at a deeper level---just afros and face paint and little doll costumes--but nothing of real substance. then again, maybe style of dress does have more substance than i'm giving it credit for: burning bras and whatnot. Eh, enough silly theorizing. The real question is: How the hell does a Japanese man grow such perfect dreadlocks? Word.
