The gonads of the Pacific pomfret pomfret <i>Brama japonica</i> HILGENDOLF collected from the area near the Emperor's Sea Mounts in the North Pacific were used for cytological observations. Mitotic nuclear divisions in spermatogonia showed to have chromosomes of 2n=54. One or two long rod-shaped multivalents frequently appeared at metaphase of meiosis I in spermatocytes.
