A new memorial commemorating those who died in the German sinking of a Japanese merchant ship in the final days of World War I will be unveiled later this year in Wales.

More than 200 sailors and passengers died when the Hirano Maru was torpedoed by a German U-boat in the Irish Sea in October 1918, just over a month before the war ended.

As one of the Allies contributing to the war effort alongside Britain and France, merchant vessels from Japan were seen as legitimate targets by Germany.
