Chinese or Japanese Bone China Coffee Cups & Saucers

Hi, could anyone give me info on these, my mum was given these as a 4 year old, about 80 years ago, the man that gave them thought they were a dolls set.

Thanks.

 

Looks like Japanese Dragon Ware.

 

We call this stuff "Yokohama" - It is porcelain from Japan with applied designs (usually dragons) in slip, called "moriage". Searching those two terms with cup and saucer should give you further info.

Your mark is upside-down but I think it's a Kutani mark

 

All right side up now.....

 

When flipped the right way up as in Aquitaine's picture, the top 3 characters read "Dai Nippon" (Great Japan in English.) First quarter of the 20th century at most recent, I think. Can be earlier.

 

Thank you all, fantastic help as always. I will get the hang of uploading photos one day!!

Thank you.
