The gakuran and the tsume-eri are the uniforms for many middle-school and high-school boys in Japan. The color is normally black, but some schools use navy blue.
The top has a standing collar buttoning down from top-to-bottom. Buttons are usually decorated with the school emblem to show respect to the school. Pants are straight leg and a black or dark-colored belt is worn with them. Boys usually wear penny loafers or sneakers with this uniform. Some schools may require the students to wear collar-pins representing the school and/or class rank.
