India-born British sculptor Anish Kapoor has created the world's first inflatable concert hall which will open on the disaster-hit northeastern coast of Japan.
The unusual 'Ark Nova', a giant purple balloon made of a coated polyester material has been erected at a park in the town of Matsushima of Miyagi Prefecture, the Japan Times reports.
The innovation was Kapoor's joint venture with Japanese architect Arata Isozaki.
The structure reportedly measures about 18 metres high and 35 metres wide, when fully inflated, creating enough room for about 500 people.
The balloon can be easily deflated and travel around the region to host events, the report added.
