Satsuma

My mother-in-law bought this vase from Maurits Lammers Antiques close to Rademacher’s outside George. She was told that it’s Satsuma, but not knowing anything about pottery I don’t know whether this is the case or whether it’s authentic (the price seems to suggest it’s probably not).

Well, it doesn’t say “Japan” anywhere, which suggests it might be original, but it also doesn’t have the cross-in-circle on the bottom, so…

Anyways, I’ve asked the nice people over at MetaFi, so answers will undoubtedly be found :-)
