Satsuma ware bowl - Kinkozan

This is a piece from our museum of a Satsuma ware ceramic bowl.
Trying to decipher the signature on the base of the bowl. Not sure about the top part which would refer to the artist and Kinkozan would have been their employer.
Anyone enlighten me about anything to do with this bowl. Information which we have is as per below.

The mark on the bottom of the bowl is 渓山 (Keizan). It is the name of the particular kiln or group of potters (within the broader Satsuma-ware producers). They are still active and they have a website, and you can see similar kinds of intricate floral motifs on their pottery still.
I don't know when your piece was produced, but I suppose you have some details on the provenance. Looks nice. Theme might be summer flowers? I can see hydrangeas, which typically bloom in June in Japan, just before/during rainy season.

Great. I tried using Google translate and it confirmed it as Keizan as well. I am sending a query to the link you sent as it does mention Keizan. Thank you!
