Looks like Geum canadense, White

To me, it looks close to BM Celery Salt OC-136. Is the picture you posted of a room in your house, or a picture you found online?

You've probably already seen all this, but just in case: this is the closest I could find https://www.etsy.com/listing/236992438/awaji-japan-art-deco-pottery-vase  And this: Export marks provide some guidance with dating. U.S. tariff law required that the country of origin be written on exported goods starting in 1890. The pieces stamped “JAPAN” were produced sometime between 1890 and 1922 when the law was rewritten, and requiring “made in” to be added to the mark. The impressed “MADE IN JAPAN” mark on Awaji pottery was used between 1922 and the kilns’ closings in 1939. The Danto Company did reopen after the war as a commercial ceramic tile manufacturer, but never made art pottery again I can't see your mark too well, but looks like it says Made in Japan? I wonder if this man could help you? https://www.tklibby.com/Awaji_Pottery.html

Thank you to everyone for chiming in. I did consider Bathsheba also but this rose has sturdy, compact canes that bloom with a single rose at the end. It doesn’t grow like a climber. My Bathsheba is a vigorous grower with thinner canes and often more than one bloom at the tip. Gentle Hermione is one I hadn’t considered. After looking at pictures, I won’t rule it out but the bloom form does appear different. Thanks again! I did come across one Austin by chance that looked more similar but it’s rare in the US. Does anyone have experience/pictures of Troilus? I happened across it being offered and when I looked at the pictures on HMF they appeared close.
