"Annales des empereurs du japon," p. 420.] ] His clan was .This warrior clan was amongst the hereditary vassals of the Tokugawa family (the "fudai") in the Edo period

Masatsuna was a keen student of whatever information was available at that time concerning the West. Since most printed material was only available in the Dutch language, such studies were commonly called "Dutch learning" ("rangaku"). Dutch Japanologist Isaac Titsingh considered Masatsuna to have been his closest friend while he was in Japan, and their correspondence continued after Titsingh last left Dejima for the last time. The oldest surviving letter from Masatsuna to Titsingh dates from 1789; [Screech, Timon. (2006). "Secret Memoirs of the Shoguns: Isaac Titsingh and Japan, 1779-1822," p. 36.] and this letter mentions mutual friends such as Shimazu Shigehide (the father-in-law of the eleventh shogun, Tokugawa Ienari) and Kuze Hirotami ("Nagasaki bugyō] " or governor of Nagasaki port). [Screech, p. 152.]

Masatsuna was an author of several treatises on numismatics. He was the first in Japan to circulate a book about non-Japanese coins with impressions taken from actual coins which had been obtained from Western traders.
