Hand-built fantasy tower stands out in Tokyo

PASSERSBY stop and stare at the ramshackle, hand-built concrete tower that looks like it has been lifted right out of a Japanese animation and dropped onto a real-life Tokyo street.

Its creator, who spent almost 20 years making the distinctive four-storey Arimaston Building, thinks his slow approach to construction can be an example to the world.

"It used to be that there weren't enough things in the world, but now there are too many," 59-year-old Keisuke Oka said inside the building's curved grey walls.

"We need to stop mass-producing things and find another way, otherwise we'll be in trouble."

With its wobbly lines and weird, wonderful ornamentation, Oka's building has been compared to the animated Studio Ghibli movie Howl's Moving Castle.

The architect himself has been dubbed the Gaudi of Mita, referencing the famed Spanish architect and the Tokyo area where Arimaston Building is located.

Inspired by Japan's avant-garde butoh dance, Oka made up the design as he went along.
