Modern Brown Drip Glaze Far Eastern Studio Vase?

Probably a long shot but any leads on this one would be really helpful. Mark appears far eastern but I'm not certain. Just curious to know any information about what style or technique this vase is and perhaps its origin. Thanks everyone.
Stands 11" high. Base measures 3.5" Weighs 1 lb, 7.5 oz.

I think it’s Japanese kanji writing on the base, but I dont recognise the style of vase. At first sight I thought it was early 20thC Art Pottery

That was extremely helpful, Naomi! You even helped me identify another vase with Kanji on the base I had lying around and found an exact match for it. So I guess a double shot of thanks is in order.
