Dates that seem fairly certain:
1) the 1933 Shure catalog showing a variety of the elephant-handled vases
2) Bill H.'s observation about the 1950s U.S. Military's Central Purhasing Office mark, found in this prior thread:
3)Fredric T. Schneider's book The Art of Japanese Cloisonne Enamel has a color photo of one of these 20th century champleve vases attributed to the Koizumi Company. (It's another example of the elephant handles style)
4) In Beatrice Quette's book, Cloisonne: Chinese Enamels from the Yuan, Ming & Ching Dynasties, there is a chapter by Odile Nouvel-Kammerer, "The Revival of Cloisonne Enamel in France at the End of the Nineteenth Century."
This is such a nice exploration of how art is affected by cross-culture transmission, it's worth the price of the book all by itself. But to condense, we could consider how 1870-1900 saw intense production of French champleve, which was displayed at the international expositions fashionable at the time. The Japanese not only exhibited at these expositions, but in their quest to achieve European standards of technological development they developed many new industries as well.
I took a tour through the current Google images displayed for the "champleve Japan," picking out the pieces similar to yours, with floral decoration and a simpler design. The date attributions by the various sellers seem worth ignoring - for example, a "Made In Japan" stamp described as "c1900," when it almost certainly post-dates the 1920 US tariff revisions that required such a country of origin statement.
Bellow are a couple of pictures quoted from this Images search.
Could the nice seal on the base of your vase perhaps indicate that is was made for sale in Japan to foreign tourists during the decades before World War I - 1920s?
Unless someone steps in and demonstrates that similar champleve vases were fashionable in Edo Japan or among Qing mandarins, it seems that the best guess we can make is "Japan, somewhere between 1880 and 1950, to be distinguished from French Belle Epoque productions."
