During the period 1919 to 1921, he made numerous climbs in
Switzerland, and on 10 September 1921, he made the
first ascent of the
Eiger by the Mittellegigrat (northeast ridge) with mountain guides
Fritz Amatter,
Samuel Brawand and
Fritz Steuri. He made a donation of 10,000
Swiss francs toward the construction of the
Mittellegi Hut. Maki's climbing career was interrupted by
World War II, preventing him from leading a Japanese expedition to the
Himalayas. In 1956, Maki led the third Japanese expedition to the Nepalese mountain
Manaslu, where expedition members and Sherpa
Gyalzen Norbu made the first ascent of Manaslu on 9 May 1956. == References ==
