Maki climbedMount Fuji at the age of ten and made many climbs in his teens, includingMount Aso. He established a climbing club while studying law atKeio University in Tokyo, from which he graduated in 1919. He continued his studies in theUnited States andGreat Britain.^[1]

During the period 1919 to 1921, he made numerous climbs inSwitzerland, and on 10 September 1921, he made thefirst ascent of theEiger by the Mittellegigrat (northeast ridge) with mountain guidesFritz Amatter,Samuel Brawand andFritz Steuri.^[1][2][3]

He made a donation of 10,000Swiss francs toward the construction of theMittellegi Hut.^[1][3][4]

In 1922, he made the first winter ascent ofMount Yari (3,180 metres (10,430 ft)) in Japan. In 1925, with five other Japanese mountaineers and three Swiss mountain guides, he made the first ascent ofMount Alberta (3,619 metres (11,873 ft)) in theCanadian Rockies.^[5] The expedition was sponsored byPrince Chichibu.^[1]

In 1926, he was again in the Alps, making the ascent of theMatterhorn via the Zmuttgrat, and climbing with Prince Chichibu.^[1][6]

Maki's climbing career was interrupted byWorld War II, preventing him from leading a Japanese expedition to theHimalayas.^[1] In 1956, Maki led the third Japanese expedition to the Nepalese mountainManaslu, where expedition membersToshio Imanishi [ja] and SherpaGyalzen Norbu made the first ascent of Manaslu on 9 May 1956.^[7][1][8]
