Antique Royal Blue Tea Set Made in Japan

My aunt gave me this tea set recently. From what I can tell it is in immaculate shape. The only thing I know about it is that the "made in Japan" logos on the bottom of each piece (some actually just say "Japan") are from a period after World War II. While I'm not 100% sure on that, that's the information I got from my research. I have searched all over the Internet  and I cannot find one single picture of this set. Any help would be greatly appreciated!
