I appreciate Wakayama University for their generosity in publishing the database that contains the diary of Lord Miura Nagato-no-kami Tametoki. My investigation of the individual was successful because I gained access to the database.
I particularly appreciate Shuya Nakamura: Tea ceremony in the official diary of Murata Tametoki, house elder of the Kishu domain, Cultural Studies of Chanoyu (Journal of Kyoto University), Vol. 6. pp. 69-136, January 2026. I found the name of the individual in the page of 129 of this article. Unfortunately, the entire content of the article is written in Japanese.
