Unusual I think Kutani? cup and saucer

Hi all,
I bought this beautiful little cup and saucer the other day.
I have seen this mark described as Kutani and the only part of the mark I could make out was the last character that reads Tsukuru which basically reads "made"
I think this is very interesting in that the design on the cup is on the inside as where all Kutani I have found the designs are on the outside. just an interesting observation or something more? Note there is a lot of gold gilt, but my photos don't show well

 

The first time I've seen that style of signature, with the script in gold over(?) a red brush-stroke.
That's gotta be of some exceptional significance, methinks.
