If it is winter now (mid June), then I assume you are south of the Equator. 6 months or so in the ground is not much time for the tree to establish so I would do nothing for the time being.

Many cultivars of Japanese maple are quite twiggy and do generate crossing branches and closely forked joints. It is almost characteristic. In areas that do not experience much of a snow load, it is rarely a concern.

At the end of winter, you can go in and remove any dead wood (gray colored stems with no viable buds) and trim out some of the smaller excess twigginess. I might also consider putting in a spacer to widen that crotch angle between the two primary branches. But I would not remove either.

As an aside, your tree looks strongly like it is one of the coral barked cultivars, most of which will always develop that tight crotch angle. As I said, it is characteristic :-)

Oh thank you, yes i am in Australia but down south in Melbourne so it gets cold but definetely no snow.

i have never heard of a spacer for a tree!

Appreciate the advice :)
