Matt black vase mark id

Hi all, newbie here. I'm working for charity shop and can't identify this combination kanji/flower motif mark on a small matt black/gold landscape vase. Vase is heavy so ceramic, does not ring, and I can feel pottery ridges inside. Is the kanji Fujita Bizan's pen name 美山? Can't find the painted flower motif. An extra mark is on the bottom rim – a number?. Many thanks in advance.

 

It's a nice Japanese Satsuma vase from around the second quarter of twentieth century. I can't read the signature but if you post on the Japanese Pottery & Porcelain Facebook page they will almost certainly translate it for you.
