The end is much newer than non-no in 1973 (Showa 48). It is a fashion check in Yokohama · Motomachi etc. (1st piece).
It seems there was also a flow opposite to that, although men's long hair and jeans were prevalent at this time around fork. It seems that girls' appearance is linked to later Hamatra fashion (2nd, 3rd).
