Hi fellow bonsai enthusiasts. Need help with my JBP. How can I increase trunk and branch thickness? Should I repot it in a training pot? Cut or reshape in any way? Any ideas will be appreciated.

You don't want to increase the branch thickness. You want thin branches relative to the trunk in order to make the tree look younger. You can, however, improve branch taper by ramifying the branches a bit. Make sure the tree is healthy and vigorous to promote back-budding, and then cut the branches back to interior buds to keep them short and dense.

As for the trunk, you could grow some sacrifice branches to thicken it, but I don't think you need to. I actually like this as a slender tree. Just let the bark continue to develop to give the tree an aged appearance. It would also look good with a thicker trunk, but slender trees are underrated.
 
As already mentioned, thicker trunk may not always be the answer but that's up to you.

Increase in trunk and branch thickness is directly related to the amount of foliage and, therefore the amount of sap and energy travelling to and from the roots. Increased foliage and growth will increase thickening. Giving it more root room will aid that. Small pots tend to restrict thickening in most species.
Is this another Bonsai Sensation tree? It appears to have been given the 'poodle cut', either from lack of knowledge or from a desire to make it saleable quickly. Not quite the type of tree I know from Tien but very like some of the pines I developed at the beginning of my bonsai journey. The problem is now you have bare branches with tufts of foliage at the ends which can be difficult to rectify.
Advice to ensure the tree is healthy and vigorous is what I'm suggesting as well. Future pruning MAY see some back buds on the bare sections but you may need to resort to grafting or a restyle if the buds won't come.
Let's just feed it and care for it well through this summer before jumping to the next stage.

Thanks for your response mate. I think you are right. I’ll just let it be the way it is.

Hi @Shibui. Thanks for your response. It’s not a Bonsai Sensation tree. I bought it from a grower about a month ago (impulse buy). I had no idea what to look for when getting a black pine and didn’t knew how hard it is to back bud. It had a “Poodle cut” and was all wired up too 😁. Bonsai sensation tree is doing well. It’s colour changed to dark green after fertilisation/ soil conditioning treatments. Also new buds are sprouting.
