A lot of age and character packed into such a small pot. I'm not sure what kind of tree it is. Perhaps and Ilex of some sort?

Continuing with our unknown artist’s tiny trees from the other day  and our love affair with small bonsai. A love affair that grows as we age (sooner or later old backs and heavy bonsai must part ways). There are no varieties listed, but some are easy. Others, not so much.

I'll guess boxwood on this one

However, we have this logo just above and this email address info@kawaguchibonsaimura.com which does contain a name or two
