Kwanko Maru
Kwanko Maru, the name of the ship, reflects the "w-glide" that differentiated "ka/ga" and "kwa/gwa" Sino-Japanese terms. Today, "kwa/gwa" terms are generally pronounced and written "ka/ga" but present-day kana orthography still accommodates w-glides, and w-glides continue to characterize the romanizations of a few words and organizational names.
Of interest here is whether the name of the ship was "Kwanko Maru" at the time of the incident, or whether the story writer is using the name of the ship that may have been given the name later that year.
According to Nagasawa Fumio's Natsukashii Nihon no kisen (なつかしい日本の汽船) <Nostalgic Japanese Steamships, Fumio Nagasawa>, the Kwanko Maru, with a displacement of 185 gross tons, was built in London in 1869 and sold to Tsushima province in 1870, at which point it was known as the Sakana. The following year it was transferred to the Japanese government, then in April 1877 -- during the Seinan War -- it was sold to the Mitsubishi Mail Steamship Company, after which it was renamed Kwanko Maru. The vessel was struck from the register of ships in 1918, nearly half a century after it was built. It spent the last two decades of its life under the ownership of a series of owners based in Hakodate.
Nagasawa's data base shows the following history.
Nagasawa Nagasawa Fumio's "Natsukashii Nihon no kisen" (なつかしい日本の汽船) (Nostalgic Japanese Steamships, Fumio Nagasawa) shows the following history of the Kwanko Maru, according to which the ship was built as the "Sakana" in London in 1869, renamed "Kwanko Maru" sometime after it was sold to the Mitsubishi Steamship Company in April 1977, and struck from the register of ships in 1918.
