ジョコンダの最初のクラックにあったハーケン・・・抜けました（汗）
There was a pitton in the crack in the beginning of the problem called "Gioconda" in Riverside area in Ogawayama, Japan's most popular cragging garden.
The pitton was not tightly fit enough... it came off, as it's shown above.
Please be carefull when you lead climb. If possible it is better to take a second protection as a redundant in the seme crack by cam.
