This beautiful little teapot (or covered creamer?) has 2 backstamps.
I had to do a bit of research, and get a little online help, to figure out this puzzle.
Noritake produced the blank for this pot. It is indicated by the plain-font Noritake Nippon mark. Dates to 1911 or later.
Royal Crockery (Nippon) decorated the blank pot. The mark indicates a date between 1911 and 1914.
Not sure if it was produced as a decorative item, an individual-sized teapot or if it is a covered creamer. The plate is the correct size for it. I will have to do more research to perhaps figur it out.
