Help With Mark On Japanese Pottery Vase

I find the decoration quite unusual for a Japanese pottery.
Hope someone can help with the mark.
Thanks

 

Korean style and technique.

 

Thanks a bunch. So, this is Japanese in Korean style or Korean made?
Do they have a name for this type of ware? Is that the artist name on the marks and will it matter or not?
Thanks

 

I don't understand Korean; all I know for certain is that the pieces I posted are Korean.

 

Thanks Khl.
Do you own the pieces from the picture?
I am having hard time finding similar online but at least now I have a starting point.

 

Those are mine.

 

I will keep searching and if I find something I will post it.
By the way, those are modern, right?

 

Within the past 25 years.

 

I like those glazes. Very ethereal.

 

Just to be clear, these are not fired glazes, though the exact technique's a bit of a mystery.

 

When I got mine at first I thought that it was some kind of lacquered ware. It just does not look like pottery. Also a bit light weight for its size.
Not fired glaze you say. Hm, wonder what it is.
Khl, how did you find that yours were Korean. Are they also marked?
