Historically speaking is that "enough food to keep someone alive for a year" or "the amount of rice one person eats in a year"?

There's 1655 calories in a pound of uncooked rice, so with 330lbs you are sitting at ~1500 calories a day for a whole year.
You wouldn't starve to death, but you'd absolutely want to supplement (both for more calories and probably for vitamins). But also you'd be eating that rice every single day pretty much, how else are you getting through that much rice?
Wouldn't you also need at least a little protein? and some lipids? For example, there is a lot more in Soylent than just rice flour. Oh, are we talking brown rice or white rice? That seems like it might make a huge difference, not only in nutrition, but also pooping.
For commoners in Feudal Japan, it would’ve been unpolished/brown rice, refining rice was labor intensive/expensive. When accessibility of white rice spread due to automation making it much cheaper, in the 1800s, it caused a huge epidemic of beriberi, which had once been a rich man’s disease, and killed a huge number of people.

the biggest problem with white rice is the lack of fiber, the somewhat high glycemic index, and it has the same problem all processed grains have: lacking potassium, iron and magnesium. these days though white rice and other processed grains all come with added b-vitamins (before that started at the turn of the century, there were massive b-vitamin deficiencies popping up everywhere). white rice has less protein than most grains but at 9% of calories, that's still not bad though some variety wouldn't hurt.
don't get me wrong, white rice isn't the worst thing in your diet but i think it's great to diversify with some whole grains and lots of beans (a real superfood), many of which can be had for 2$ to 3$ per 2k calories.

Err (150kg)(3500kcal/kg) = (5.25E5 kcal/E_koku)/(365 days) = ~1500 kcal/day. So not great working in the field or fighting for the average guy. But I feel like this is one of those things where the average lord didn't count how many fish you caught or what have you. So I bet if you had miso, fish, and like some vegetables from the outside your house, you would probably survive alright.
EDIT: the actual point is that it's probably not literal. Ease of quantifying and transporting dried rice over long distances without refrigeration probably had a lot of how they ended up with a Koku as useful measurement.
That much brown rice will have around 12 grams of fat and 35 grams of protein.
How much protein do you want for "at least a little"?
Supplement with the 50lb bag of beans that sits 20 feet away from the rice at my Costco and you are pretty much there.
rice and beans is a complete protein

I interpret as the latter:
> As a rule of thumb, one koku was considered a sufficient quantity of rice to feed one person for one year.
I assume "sufficient rice" means it needs to be supplemented, and this is supported by the footnote as well:
> Apparently 1.8 koku (1 koku and 8 to) was actually required for nourishment by a man each year, according to the conventional wisdom documented in a "home code" (kakun [ja]) of a certain merchant family in the Edo period.
