HOKO SUISAN K.K.

H240, recorded for Ohtsu Maru in April 1965, has a green funnel with a black top separated by a broad white band bearing a red “H”. The flag is white with a red “H”.

Eniwa Maru at Lyttelton on 21 September 1985 showed H241: a black funnel with a white panel edged green and a stylised “H” formed by double green lines. The flag is green with a white frame enclosing an “H” formed by green lines edged white. The observation describes the flag panel as square on a rectangle.

After docking, Eniwa Maru was seen at Lyttelton on 9 November 1986 with H242, a green funnel and white panel carrying the double-green-line “H”. The same later flag is associated with this version.
