Japanese Joinery Square Build

Here was a challenging project from a few years back that I neglected to post. It involves some difficult joinery.

It looks great from the side.
But the joinery in the back is not so nice. It's functional as a square, though, so I'll take it.
The project was mostly an exercise in chisel work to clear out the wood.
