[The bulletin of Nariakira Shimazu].

In 1858, the sudden and fatal illness of Nariakira Shimazu, the feudal lord of the Satsuma clan, provoked suspicion as to the cause of his death. Nagahiro Kuroda, the feudal lord of the Fukuoka clan, sent a letter to Munenari Date, the feudal lord of the Uwajima clan, informing the results of his investigation, along with the bulletin on Nariakira written by Hoshu Tsuboi, a clan physician. While the author was emending the texts of the bulletin, he found that there are two series of historical materials; dated in August and dated on July 16th, the day Nariakira expired. After examination of those materials, the author also discovered that some corrections may have been made at the office on the original text of the bulletin for compilation of the Shimazu documents in the Meiji era. In the present communication, the author reports the process of the study and the contents of the bulletin.
