"Jap" is a pejorative dating back to the Second World War. Weeping Japanese lace-leaf maples of the size shown here are worth thousands of dollars on the retail market. Specialists in large trees catering to the demand for instant landscaping here "mine" them from old properties and re-plant them elsewhere, getting again, thousands of dollars for them in the process. If there is one of these kinds of operations working your local area you may be able to get one of them to take yours away for free, if nothing else. Of course, they may want to be able to drive up to it with a machine and scoop it up all in one move. With the tree right in front of your house, with buried utilities perhaps present and a lawn you want to keep this may not be feasible.

If you are wondering the taller shape shown in the Dig Doug cartoon would be achieved by installing an adequate stake and training the existing specimen up, to be more tree-like. And visually effective.
