Japan & Pembrokeshire – the HIRANO MARU
On 4 October 1918, the HIRANO MARU, a merchant ship owned by the Nippon Yusen Kaisha Line, was sailing from Liverpool to Yokohama via South Africa with 320 crew and passengers and a Scottish Captain, Hector Fraser. She was in a convoy escorted by an American destroyer, the USS STERETT, to give protection against attack by submarines.
When she was 200 miles south of Ireland, she came into the sight of UB 91, a Class III German submarine commanded by Captain Wolf Hans Hartwig. A torpedo hit the HIRANO MARU and she sank in seven minutes, going down so quickly that her few undamaged lifeboats could not be launched. The USS STERETT also came under attack and was stopped from rescuing the struggling survivors.
Nearly 300 men, women and children perished in the dark, cold and stormy sea. Bodies were washed up all along the Pembrokeshire coast. At least 11 bodies were picked up on local beaches and have been buried as ‘unknowns’ in nearby churchyards and cemeteries. Records show that there were such burials in Marloes, Dale and St Ishmaels. Some victims were able to be identified and they were buried at Milford Haven and Angle, where a memorial was also erected.
This memorial has now been replaced by a new granite memorial (inset drawing) unveiled at a centenary ceremony on 4 October 2018. The inscription in Japanese, Welsh and English reads: ‘Here lies Shiro Okosie and nine of his unknown shipmates who died when the Japanese Passenger liner HIRANO MARU was torpedoed off shore of Ireland 4 October 1918’ it was suggested by Ms Yuko Tsutsui, Senior Director of the Nippon Yusen Kaisha Shipping Line, former owners of the HIRANO MARU.

The ‘U-Boat Project’ commemorates the Great War at Sea around the coast of Wales. It is a 2-year Heritage Lottery Funded partnership project led by the RCAHMW, with an overall value of £1M, which provides unprecedented access, for the first time in 100 years, to the remains of 17 wrecks on the seabed off the Welsh coast which are part of our Great War heritage, but which remain under-researched and under-valued.
