I received a new Japanese black pine from a local nursery man for an excellent deal. He said it is grafted and is a type that was popular with bonsai because of the rough bark that forms quickly, but the exact variety is unknown. It has been in its nursery can for A very long time without repotting. It has also not been appropriately fertilized. Not sure if this tree is destined to be a bonsai, or just a really great large container tree, but the first priority is to get it good and healthy.DF2EDDD9-9E4F-476F-BD94-059CD47A38DA.jpeg
It is 4 inches across the base.

even the branches have great bark.

I plan to gently repott it into a larger container for now with some good fresh substrate to try to improve the health of a tree overall. My question is does anybody recognize this Foliar disease. Not sure if it is fungal, sunburn, or just poor care.

Yellow or brown bands across needles is indicative of Dothistroma - Needle cast. Nothing you can do about the already damaged needles but fungicide spray as the new candles open will help reduce infection in new spring needles.
Brown tips could also be dothistroma but possibly dry at some stage.

If it is grafted they did a bloody good job of it. I can't see any sign of a graft union.
The tree looks a bit long an leggy but has some great bends and twists so lots of potential.

Thanks, I thought it might be needle cast I will treat in the spring. I know it is grafted, but there’s clearly no sign of the union.
