Sachi Amma

Sachi Amma, born in 1989, is a Japanese professional rock climber and sport climber. He began competing at the IFSC Climbing World Cup in 2006, mainly in the lead discipline, and won the overall Cup twice, in 2012 and 2013, with only occasional appearances in bouldering. Although he climbs mostly indoors, he is also regarded as one of the strongest outdoor sport climbers in the world, having redpointed several routes of the 9a+ grade in Spain and France and two routes of the 9b grade, including Soul Mate at Gozen Iwa, which is described as the hardest sport route in Japan.
