Need help with porcelain mark

I recently obtained a square sided vase with 2 different beautiful patterns and vibrant colours. It seems relatively new but was intrigued by the mark which I have been unable to locate on websites such as Gotheburg.

Any help would be appreciated

 

I know this is not too helpful, but the mark is Japanese and upside down.

 

You're always helpful !!!

 

From the style I suspect it is a Chinese vase inspired by Japanese work, looks decent quality although it's probably not very old. Best guess at the mark is 佶山 (Jishan) not that it helps here.

 

Thanks for the information. At least now, I know it is Japanese!!

 

Thanks for the reply. At least I know a bit more now
