Kazuma Ise of Japan has climbed the 8C / V15 “Byaku-dou” in Horai at only 17 years old. The route is a Dai Koyamada project originally put up in 2003 featuring a steep overhanging set of terrible pockets.
Mishka Ishi at 13 years old has today become the youngest person to climb a V15 / 8C boulder problem. This is a truly astounding feat, given that only three women have ever climbed V15. Ishi is a year younger than the previous youngest – Ashima Shiraishi
