Thank you, for your detailed answer, susan.

I misunderstood why my "huge" was wrong.
Now it is clear.

So Sumo-wrestlers in Japan are described as "huge", for sure.

Thank you for the picture of the huge building of NASA.
I would like to see it someday.

BTW, just out of curiosity, why the national flag is not only vertical but also "inside-out" in that huge building?
