One hundred and twenty stranding events of Stejneger's beaked whales were reported in Japan between 1999 and 2011. The purpose of this study is to introduce pathological data and to discuss probable causes of death for 44 Stejneger's beaked whales among them. The significant pathological findings were the pulmonary edema, parasitic granulomatous nephritis, emaciation, amyloidosis, suppurative bronchopneumonia and so on. The probable causes of death were categorized as noninfectious in 43 of the cases, which included drowning, starvation and secondary amyloidosis. One individual was diagnosed with septicemia, which was the only example of an infectious disease. Because we could not always perform advanced analyses, such as microbiology tests, biotoxin examinations or contaminant analyses, the finality of our findings may be impaired. However, the present study has broad implications on the causes of death of Stejneger's beaked whales of the seas around Japan, which are valuable for the future studies and for the detection of emerging diseases.

Postmortem examination was performed on a female western gray whale (Eschrichtius robustus) stranded at Tomakomai-shi, Hokkaido, Japan in August, 2007, and amphipod whale lice (Cyamus scammoni) and cirripedian epizoites (Cryptolepas rachianecti) were obtained. The histopathological investigation of the epizoites was given. 2007年8月、北海道苫小牧市の海岸でストランド(座礁)したコククジラ(Eschrichtius robustus) 雌1個体の外部寄生虫クジラジラミ類(Cyamus scammoni)と着生生物フジツボ類(Cryptolepas rachianecti)について、日本では千葉に続き二例目の記録をした。また、C. rachianectiの着生部位における組織病理学的検索も実施した。
