39th Bunkamura Gallery Auction

The Bunkamura gallery's annual auction returns with a selection of around 400 pieces, including art by names like Picasso, Yayoi Kusama, Taro Okamoto, Tadanori Yokoo, Mika Ninagawa and sculptor Alberto Giacometti. And if those sound a little out of your league financially, make sure to pay attention to the wealth of lesser-known but interesting work on offer as well. Smart collectors will also want to check out the after-sale event, featuring art left unsold at the main auction, taking place from May 4.
