I bought a Kyushu Hydrangea plant 2 months ago from a nursery, now its leaves are gradually wilting/dying, from the bottom up. What can I do to save it?

Ajisai is the Japanese word for Hydrangea, while there are many varieties, I have never seen one like your picture, It almost looks like it was grafted onto a tree rose.
If I were you, I would return it to the nursery where you bought it.
It looks like you purchased the tree form of Paniculata Kyushu. I've never owned this type of hydrangea, but I have been told it is a "finnicky" variety. As with all hydrangeas, Kyushu likes a well drained soil. If the soil doesn't drain well and holds too much moisture around the roots, the plant will die from within. It may be that you are over-watering, or you have poorly drained soil. Could either of these be the cause of your Kyushu dying? good luck, Matt
Here are some nice pictures of it:
Could there be damage to the trunk? Especially where your stake ends below the branching point, that trunk looks delicate and needs a better stake.
