Japanese vase with six kanji mark - Dai Ni Hon Matsumura Zo

                                       

hopefully this can be identified.... i'll search gotheborg right away
but what for?

Looks like Japanese Hirado porcelain (if you google Pair Of Japanese Hirado Porcelain Vases you'll see something similar), however I'm not seeing the quality of a 19th Century piece, so I suspect it's early - mid 20th Century - later, if the blue bird and foliage decoration is transfer printed rather than hand painted.
The characters are quite sloppily done - the one on the middle right is supposed to be two box-like characters, not one, and the character bottom left has an uncharacteristic 'smilie face'. The one top left is supposed to have four strokes along the bottom. All in all, this adds up to a faked mark or one done by an unskilled potter.

dear Naomi,
the blue bird flower etc. and foliage decoration is handpainted.
i was told some minutes ago that the right stack of the mark reads top down 'Dai Ni Hon = Great Japan' and the left stack is supposed to be a kiln or signature. I was told as well that "the date is most likely between 1891 and 1921 when the 'Great Japan' in kanji was required for imports to the U.S.A. After 1921 the requirement changed to 'Made in Japan', but i was told as well that there are exceptions.
I'm an absolute amateur with asian porcelaine.
and I think I'll be that for ever....
but anyway thanks a lot for your help as usual

seems to be Dai Ni Hon Matsumura Zo
