without pics, I can't do much research for you values have a range So, two options: post a pic of the vase and the backstamp, or go here:
www.kaleden.com select pottery/ porcelain and then on the upper right, "fine tune" it by entering Nippon vase.
What I can tell you is that your vase was more than likely manufactured between 1891 to 1921, when they changed the wording from Nippon (which means Japan) to Japan, (and a bit later, made in Japan).
For your mark: check out
www.gotheborg.com, (an immense site takes a bit to load) and go to Noritake.
And remember condition counts a lot. Just one tiny chip that hardly shows can skew the value tremendously. Best wishes, and if I can be of further help, please post back KB
