Koyamada on last year’s Byaku-dou (V15)

Another V15 for Koyamada

The prolific Dai Koyamada has climbed another V15 (8c) boulder problem in Japan. Methuselahzation is a 25-move problem at the Yatsue area in Kagoshima, near the southern tip of the island. In November of last year, Koyamada established Byaku-dou at Hourai, a problem he called “at least V15.” The 25-year-old also has climbed four V14 problems at Hourai, as well as numerous hard boulder problems and sport climbs in Europe.
