Watermelons are ritually split in Obanazawa while Chrysanthemum flowers in Itoshima City, Fukuoka are readied for the upcoming Bon festival. Meanwhile, works of ‘procedural architecture’ by the duo Shusaku Arakawa and Madeline Gins explore ideas of life and possibility at the Aichi Arts Center for this year's Aichi Triennale in Nagoya. Their model for unbuilt project Bridge of Reversible Destiny from 1973-1989 is a rite of passage. And Reversible Destiny Lofts—Mitaka (In Memory of Helen Keller) from 2005, resonates with splitting fruit and floral tributes in the build up to Obon, a festival that bids one thing farewell, then welcomes something else in its place.
