When it comes to introducing the Megastructure, I believe this is the place to begin.
The Japanese characters, from top to bottom, mean Megastructure.
超 – “hyper”
構造 – “structure”
体 – a suffix denoting physical entity (for instance, as opposed to a sentence structure)
Together, it is pronounced chou-kouzoutai.
