Old Victorian cup & Saucer maybe too old for here sorry!!!!

Purchased these today in a box of pieces at my first auction i was not brave enough to be there and bid from home which was fun sadly the box in question had a glass
vase in i wanted which turned out to be broken and stuck together but there were a few interesting pottery pieces in it and i thought i would try and research although i am a novice on pottery so any information i can get would be a great help. I think these are Victorian nicely enameled maybe continental but has a strange mark on the base almost like Asian writing finding nothing similar at the moment. Thank you for having a look.

This is Japanese and says Tashiro. You can read about it at gotheborg.com if you click on Japanese marks on the left and scroll down. They went out of business in 1937.

Thank you very very much i did not expect such a quick response on this item
