Mitchell’s Asakirisan Maru reference confirms the principal Kobe attribution for Rosanoski; Brown’s Osaka location appears incorrect. Mitchell also shows this funnel on the agency vessel Mount Ranier. Many ships in his drawings have European names, suggesting chartering.
The principal Kobe company appears in Lloyds from 1953. Rosanoski tentatively connects it with a 1978–79 joint venture with Sankyu Unyu Kiko and the later Tokyo-based owner, manager and agent, both associated with Unkai Maru. Financial difficulties in 1985 led to attempted restructuring, bank foreclosure and bankruptcy on 25 February 1986.
Earlier correspondence described the Kobe operation as lasting until the early 1970s; Rosanoski’s later note connects previously separate entries, extending the account. The source warns that Nakamura Kisen is a common company name.
Japan, Kobe; Brown gives Osaka.
