Mount Bona. Apparently two Japanese parties climbed Mount Bona (16,500 feet) in 1977. From information in Iwa To Yuki the second party made the eleventh ascent of the mountain and the sixth Japanese one. They followed close on a party from Kawasaki City. The party from Hokkaido was led by Isao Tomita. They climbed the peak by the east ridge with two high camps. On May 25 the leader, T. Kubota, Y. Koyama and Y. Tsunemoto reached the summit.
