Neither Chinese nor Japanese have circles in their characters. So it probably would be Korean. I recognize four letters that mean "humanity", "peace", "ancient", and "precious" so it is probably a Buddhist thing. However, the letters for "humanity" , "peace", "ancient", and "precious" are the same for all the three languages, so it is not saying much.
I can't really tell from those pictures, but it might be one side Korean and one side Chinese.
However, it has a Chinese seal on the bottom. I can't read it because it is upside down. It says something like the pottery is made in the workshop of Chen somebody, which means it might be manufactured in Southern China or Taiwan because the majority of people with the surname Chen live there.
Cassandra is right about the firing technique. We have a lot of such kilns in my hometown (Nantou). It would be really cool if it originated from there.
