No, but it is a carbohydrate. A diet that gets 80% of its calories from carbohydrates is not what most people here would call "protein-rich."
There's a detailed calorie breakdown at
Macronutrient ratios: 9% protein, 85% carbs, 6% fat
Grains account for 19% of total calories, sweet potatoes for 69%
(Note that this link draws on earlier data than the one you posted. The global decline of traditional food cultures is a whole other topic.)
And as more and more Chinese people have gotten rich enough to afford to eat like that, Chinese people have begun to suffer from the same "diseases of affluence" that Americans do. Hardly a ringing endorsement.
FWIW, the Chinese people I've personally shared meals with ate plenty of rice.
Not in my wife's family.
And so, you still haven't shown that they EAT GRAINS as their main carbohydrate. You'll notice that on your link only 19% total comes a combo of rice and grains. So out of their carbohydrate consumption, the majority (81%), doesn't come from grains.
In fact notice HOW MUCH FEWER rice and grains the consume compared to mainland Japan! That's going by your own stuff.
