Rectangle coat from odds on by akira onozuka (later the founder and designer of another japanese label, zucca). Has a two way (buttoned up vs folded down) collar, covered front placket, welt pockets at the waist, tab and button cuffs. Fabric is a dark grey cotton with slight sheen / unusual surface feel, may be waxed or coated.

Coat has stylistic similarity to issey miyake coats from the same period - may be because okira onozuka worked for miyake prior to founding own company. According to garment label, coat is from 1987-1988 "Acrobat Paradise" collection. 

Good condition, with some fading and several small marks (see pictures)
