The Japanese Dai Koyamada has established another long boulder problem that may be harder than V15, according to www.8a.nu. Koyamada added a six-move, V11/12 sit start to his existing problem Hydra (V14) at Shiobara, Japan, to create Hydrangea (V15/16). The complete problem has 25 moves and spans about 45 feet, including a 30-foot horizontal roof. In its length, Hydrangea resembles Wheel of Life, the possible V16 that Koyamada established last spring in the Grampians of Australia—at 76 moves, this bouldering route really deserves a sport-climbing grade, and indeed Koyamada suggested 5.15a.
