Good day to you gentlemen. 
I'll do this quick.

I'm working on a translation project and I want to clean up (removing) the Japanese characters in this pictures.
Now, my methods are varied. Of course , I could always delete the letters crudely and then try to fix the image pixels by pixels. But that will take too much time and I won't be able to guarantee the picture will look the same.
So how do professionals work on the things like these ?
My appreciation in advance.
