One additional question. An email from a Japanese correspondent which I just received stated (excerpt anonymized): * * * 'I couldn't find the exact name of 'Ihiro Wan'. 'Wan' means a bay in Japanese. I found that 'Hiro Wan' exist in Hiroshima. There was major naval port of Kure located in Hiro wan.' * * *
How far away would this naval port be from the city ?
(My original question to my correspondent was

I own one myself which has its metal buttplate coarsely engraved with the words 'IHIRO WAN', maybe by the US soldier who captured it (more realistically: picked it up somewhere in a warehouse).
Would you happen to know whether 'Ihiro Wan' is a town/city, an island, a bay, a ship's name or whatever ? Was there any kind of military action ?
