X-Seed 4000

X-Seed 4000 is a proposed skyscraper that looks oddly like Mt. Fuji. Perhaps it’s unsurprising that it could be eventually built in Tokyo, Japan. The tallest building ever fully designed, the X-Seed 4000 would house between 500,000 and 1,000,000 people. A tiny quantity of individuals, if you take into account that the technology to “fabricate” mature adult individuals from raw materials is probably only a few decades away.

The X-Seed 4000, which would be 4,000 meters high (13,123.2 feet), would in fact be taller than Mt. Fuji, which is merely 3776 meters high (12,388 ft).
