I don't really get the "Yearly" Rewards.

Pretty much this. OP is just trying to continue the complaints about "China gets X, so I want X too!" without understanding why something exists and why something else doesn't. Such as the generic kabuto being... oh I don't know... for a future Samurai job. The one in the image holds no New Years significance at all. Likewise the outfit that China gets is not a New Years thing by implication. The cheongsam is simply an elegant Chinese dress that is commonly worn for events (like New Years, weddings, fancy old school dates, etc). Red being the color to ward off evil spirits from ruining the occasion. None of that represents anything about New Years for the west nor Japan.

Oh?

So what about all the Chinese Immigrants who came to the US and stayed? The US for example has no real culture, its a mix of thousands of them. I don't understand the logic, maybe someone wants to celebrate it here?

However this isn't about just that. I just don't see why they bothered making the helmets.
