Noritake Japanese Tea Set

I had forgotten my mother gave me this Noritake tea set; just discovered it in a box as I was cleaning the attic area. It has 5 cups (one was likely broken long ago) and teapot. She said she got it when she was married in the late 1960s. I can't find anything about it online, anyone have any idea if it is from the 1960s? I am going to make myself some tea later today!
