Grades follow the Japan Meat Grading Association: yield grade (A–C), meat quality grade (1–5), and marbling as BMS No. (1–12). How Japanese beef is graded →
The conditions come from the designated goods of the regional collective trademark held by JA Shimane: beef of never-calved Japanese Black heifers born and fattened in the Oki Islands. A shop in Ama Town (okigyu.com) adds “meat quality grade 4 or higher”, but we have not found this in the rights holder's own material, so grading is left as not set.
