Two foramina and related accessory foramina are present at the labial surface of the mandible in Japanese macaques. However, the correlations between the shape and the location of these foramina haves not been precisely reported. These foramina may indicate the course of the nerve and arterial supply. Materials and methods Dental cone beam computed tomography (CBCT) was used to evaluate the morphology of the mandible in Macaca fuscata using the osteological collections of the Dept. of Neurolo, Gross Anat, Kagoshima Univ. Grad. Sch. Med&Dent. This study focused on the morphological features of the foramina and the relationships between the primary foramen and the accessory foramina in the Japanese macaque. Results We investigated the multi‐foramina structure of the Japanese macaque mandible using CBCT and observed the morphological structures of the mental foramen and accessory foramina at the labial surface of the mandible using 3D images. The lingual multi‐foramina were also identified at the anterior lingual surface of the mandible. We classified three types of canal from 3D images, a tube‐like shape, a funnel shape, and a branched shape. The two canals were found in six cases (42.9%, 6/14) and contained nerves and blood vessels, which could be observed macroscopically. The nerves and blood vessels in the multi‐foramina supplied the soft tissues of the labial and lingual regions of the mandible.
