The livery adapts the parent company’s, with chartered vessels sometimes changing the funnel base colour. Toko Maru in June 1962 was reported very dark blue; Hokko Maru, Seiko Maru and Nanko Maro sightings instead gave light blue. Suruga Maru at Lyttelton on 17 May 1985 was light, bright blue. The earlier vessels were registered to Nippon Suisan, with Toko Maru and Seiko Maru later under Nissui.
