Japanese White pine soil type?

Hi all, 

I've recently been given a Japanese white pine (Pinus Parviflora). It's currently in a small pot but I was hoping to put it into a bigger pot to train it into an ornamental tree with a bent trunk. It'll eventually go into the ground but because of garden changes I wanted it in the pot for now for safety. 

What soil would be best for the tree? I've read everywhere about Well drained soil with adequate moisture, but what does this mean exactly? Is there a specific soil to get or should I make something with sand etc and if so what amounts? 

Thanks for any help

    Many species of the genus Pinus inhabit areas of relatively impoverished soil , avoiding
    calcareous (chalky) ground .
    Neutral to slightly acidic , free draining (not waterlogged) , in other words retaining enough moisture for good growth . Full sunshine is also vital .

    Japan has volcanic soil.  So acid.  I would buy a bag of John Innes ericaceous compost, that should be OK.

    nb. Most gardeners use the term "soil" or "top soil" for the stuff in the garden.  For a pot a more careful blend is needed, which is called "compost".  "Garden compost is the stuff you make yourself and on its own is not suitable.
