Neither source mentions the article as being in Japanese.

"Cartouches." Imago Mundi, 27(1975), 8. A short anon. article, but easy to check out.
In Lloyd A. Brown's 1949 Story of Maps, pp. 174-75 are on cartouches.
The following, a history of the development of the symbols key on maps, may be useful, since
those often occur within cartouches: Schilder, Günter. "Historische ontwikkeling van legenda's: een verkenning" Kartografische tijdschrift, 9(1983), 19-28.
The
following several works, while not specifically on cartouches, should
contain substantial information on the subject, being on the decorative
and artistic aspects of old maps:

Lynam, E. "Period Ornament, Writing and Symbols on Maps, 1250-180." Geographical Magazine, 18(1945/1946), either at pp. 323-26 and 265-68, or at pp. 365-68 (I have conflicting citations)

Finally, there is Seifert Traudl's book, Die Karte als Kunstwerk,
etc., of 1979, mentioned above in connection with Hedergott's work, and
an article by the same author and with the same title, probably a resumé of his own book, in: Deutscher Verein fuer Vermessungswesen, Landverein Bayern. Mitteilungsblatt,
32 (1980), no. 2, pp. 125-34; and, in case you can read Hungarian, or
in case there is a resumé in another language: Hrenkó Pál. "Térképi dīszītörajzok szakmatörténeti adalékok." Geodézia és kartográfia, 30(1978), no. 6, pp. 441-51, which my source translates as "Map Cartouches, and Contributions to Personal History", which is
probably off. Hrenkó Pál is a big name in Hungarian history of cartography.
