The Tsūshōgō was the combination of Heidan-Mojifu (兵団文字符?, 'force cord') and Tūshō-Bangō (通称番号?, 'cord number') . Heidan-Mojifu was the kanji code assigned for every division, independent brigade and other larger unit. Each Heidan-Mojifu usually consisted of one kanji, but some units established in the last stages of the war had two-characters codes. Unmobilized units were assigned area codes, such as 東部 (Tōbu, 'east area of Japan'). The Tsūshō-Bangō was the 3-5 figures code number assigned for every IJA unit.
