This funnel appears on refrigerated tuna carriers including Tuna Queen, Yakushima, Lady Tuna, Satsuma, Harima 2 and Tuna Princess. Its white bands become horizontal aft and rise on the starboard side as a mirror image. Attribution was initially considered through Alavanca, Star Navigation, Yamane and manager Shinko Kaiun. Rosanoski later favoured a charterer: the colours occurred across ownership groups and on Harima 2 before Shinko was recorded as manager. Lady Tuna was identified with operator MRS Corporation, a wholly owned Mitsubishi company operating ultra-low-temperature transport vessels. On 29 November 2013 Rosanoski therefore tentatively reassigned the livery; he did not establish that every photographed ship shared that operator.
