Mu minsi ishize, ubwo isoko ry’ibikoresho by’icyuma rikomeje kwiyongera, inganda eshatu zikomeye zo mu Buyapani zazamuye inyungu zazo mu mwaka w’ingengo y’imari wa 2021-2022 (kuva muri Mata 2021 kugeza Werurwe 2022).
Ibigo bitatu binini by’ibyuma byo mu Buyapani, Nippon Steel, JFE Steel na Kobe Steel, biherutse gutangaza imibare y’imikorere yabyo mu gice cya mbere cy’umwaka w’ingengo y’imari wa 2021-2022 (Mata 2021-Nzeri 2021). Imibare igaragaza ko nyuma y’uko icyorezo gishya cya pneumonia kimaze kugenzurwa neza, ubukungu bwakomeje kuzamuka, kandi icyifuzo cy’ibyuma mu modoka no mu zindi nganda z’inganda cyariyongereye. Byongeye kandi, igiciro cy’icyuma cyatewe n’izamuka ry’ibiciro by’ibikoresho fatizo nka amakara n’amabuye y’agaciro. Nabyo byazamutse uko bikwiye.
