It is noted for the Asahi Flame, an enormous golden structure at the top, said to represent both the 'burning heart of Asahi beer' and a frothy head.[2] The 360-tonne golden flame was made by shipbuilders using submarine-construction techniques.[citation needed] It is completely empty.[citation needed]
The Asahi Flame is often colloquially referred to as "the golden turd" (kin no unko, 金のうんこ) and the Asahi Beer Hall itself as "poo building" (unko-biru, うんこビル) by many Tokyo residents.[citation needed]
