American comic shops in Yokohama?

My son is a big Batman fan and needs his fix of comics. Are there any shops in Yokohama that sell them?

Is a little old information, please refer to the here reference.
I do not know whether there was a cartoon, I think it's Takahashi bookstore of English books are selling a lot.

However, the store is not very widely.
Not listed here, but Yurindo The Diamond shop of Yokohama Station West Exit sells many comics.
However, I do not know whether there is a English comic.

If I see earlier of the list again,
Kumazawa Shoten Landmark Plaza is likely there are many best Books in Yokohama.
