DIY: Weight reduction/Fix hatch not opening issue

It looks like a mass damper to eliminate some resonance, rattle or vibration. Maybe from the exhaust at certain engine speeds of from road input.

I've been told that it's to help petit women on Japan to close the hatch. Why it's rubberized and overly complicated, not a clue

It may serve more than one purpose. Since the hatch is light-weight Aluminum, the weight may give the hatch some extra inertia to make the latch when closing. It can give the consumer the impression of higher quality (hatch doesn't feel as flimsy and has a bigger "thunk" when it closes). Personally, I like Enough's anti-NVH theory.

Good thread- this is almost certainly the function of this part rather than making the hatch easier to close. If that was their aim, why not simply make the gas struts less strong.

Lots of oems use mass dampers for NVH reasons, limiting vibration or resonance.

Maybe, but some have it, some don't, and it makes literally díck difference on NVH
