Ye just dropped a fortune on one of the only homes in the U.S. designed by famed Japanese architect Tadao Ando, so the place is a house just as much as it is a work of art.

The nearly 4,000 square-foot Malibu property hit the market last year for $75 million, so Kanye got a pretty good deal at $57.3 mil to add to his collection of homes all over the country.

The house sat on the market a long, long time ... it was listed in May, 2020.  Our real estate sources say the house didn't sell quickly because it's small and it's attractive "to a very specific buyer" -- translation, it's not for everyone.

The 3-story sculpture-esque home also resembles a military bunker, with tons of concrete and reinforced steel to go with the 4 beds and 4.5 baths ... and it sits right on the beach overlooking the Pacific.

Kanye's new pad is only about a 30-minute drive from the massive Hidden Hills compound he built with Kim Kardashian ... where his estranged wife and their kids still live.
