Japanese Bronze vases

Hi I’m trying to identify this makers mark..any help appreciated. Pair of Japanese bronze vases about 1ft tall. Mark is on inside base of one vase only faintly visible, see photos.
Thanks Andy

 

Hoping this close up will help with your identification

I have a magnifying app on my phone that is very useful in taking such pictures. It is free, but the one with the light costs $1.99. I used Magnifying ++ but there are many to choose from. Good distinct pictures of marks will help you get the help you would like.

I use the Magnifier plus app, also free, it also has a magnify slider and an (EV) exposure slider, it has a light button. I've used other ones and this is my favorite one.

 

Thanks guys I’ve downloaded the app, this is the best I can do. The mark is faded toward the bottom.
Thanks Andy
