It's a pretty vase, but with that sticker... it is not 100 years old.
Early Japanese ceramics were scribed, in Japanese, by the artist or manufacturer. Later, they were designated as coming from Nippon. The U.S. Customs Bureau ruled that "Nippon" was no longer an acceptable synonym and as of August 1, 1921 all goods were supposed to be backstamped "Japan". Technically, the Made in Japan Era began when NIppon era ended in 1921, but it really was not that precise. At some point the U>S> Customs Bureau may have required that the words," MADE IN" be added to the backstamps, but this was not always done. Unmarked pieces sometimes slipped through Customs ,but most of the ceramics from 1921 to 1941 are marked either "JAPAN" or "MADE IN JAPAN" .
During WWII, no Japanese ceramics were imported to the US. After the war, during the 1947-1952 period, they were marked with a sticker that said OCCUPIED JAPAN or MADE IN OCCUPIED JAPAN.
When the Occupation ended in 1952, marks no longer contained the work "Occupied" so pieces were again marked only with "Japan" or "Made in Japan". This is when the paper label era really began. Prior to WWII, paper labels were flimsy and the glue was often not strong, so the Customs Bureau usually made importers replace the labels with indelible ink backstamps. In the 1950's, technology improved and paper labels were allowed. The two most common types of labels are Small oval or rectangular blue or black paper with white letters; Two -color metallic, such as black or red with gold or silver lettering.
I would say from the look of the sticker, and the artwork motiff that it is probably from the '60s or later.
