Where is (was) Yoshu?

[Bruce Pennington]

A star-stamped RJT blade with mei "YoShu Seiunshi HisaTsugu", according to the website.  Seiunshi Hisatsugu is listed in the RJT roster, but I don't see a "Yoshu" in the prefecture list.  Wiki says it's "Yamashiro".  Is that an appropriate province name to put in my RJT charts?

Yo Shu 豫州 is the old kanji for 予州, Iyo 伊予 in Shikoku.

Excellent! Thanks guys!

 

Another WWII smith not in Markus' list, but he is on the RJT list of Japaneseswordindex.com

@Bruce Pennington he is  IMAI HISATSUGU (今井 久次) Ehime. Example mei: “Hisatsugu” (久次). “Yoshu Seiunshi Hisatsugu saku” (豫洲青雲子久次作).  Well covered in this "excellent" paper.............

listing in Sesko:  HISATSUGU (久次), Shōwa (昭和, 1926-1989), Ehime – “Hisatsugu” (久次), family name Imai (今井), born 1892, rikugun-jumei-tōshō, he studied under Takahashi Yoshimune (高橋義宗), jōko no jōi (Akihide)

Ok.  I saw the Sesko listing but was confused because the JSI RJT listing has both Imai and Seiunshi as if they were 2 different people.

 

Now, what do I do with "Iyo" vs "Ihime"?
