was President (from 1954), then International Commissioner, and Chairman of the National Board of the Boy Scouts of Japan. An engineer, he had a successful career in mining engineering. He was also an accomplished author, published several books on Indochina and Manchuria, and short stories in addition to scientific publications related to his work.
He was the discoverer of Hakore hot springs.
In 1888 (Meiji 21), Hidesaburà  was born as the second son of Chà «hachi Nakano VI and Mine Nakano, who had ran a pharmacy in Kyoto for generations. Chà «hachi VI died in 1904, and then his elder brother, Chà «zaburà Â, inherited family business and their father's name to became Chà «hachi Nakano VII.
Hidesaburà  entered the Second Middle School of Kyoto, but he failed to graduate in prescribed five years. Then he transferred to the Nihon Middle School in Tokyo. After graduating the middle school, he enrolled to the Third Higher School in Kyoto. Since he was so engrossed in rowing there, he decided to progress to the department of mining engineering in Kyushu Imperial University, which was newly established and admitted students without an examination.
In 1914 (Taisho 3), just after graduated the university in July, he found a job in the South Manchuria Railway and soon served 18 months of military service as an engineering lieutenant. In September 1916, he returned to Japan and entered to the Ministry of Agriculture and Commerce. He got the job at Sapporo mine superintendence bureau. At the same time, Chà «hachi VII and Kurushima Takehiko, who were working together in Boy Scout activities, had a plan of marrying eldest daughter Fukuko of Takehiko with Hidesaburà  to let him inherit Kurushima family. They held a wedding ceremony at Tokyo Daijingu in April 1918, and Hidesaburà  took the surname Kurushima.
On 14th June 1920, the explosion occurred at Yà «bari coal mine and more than 200 miners trapped inside the mine. 10 or more hours after the first explosion, Hidesaburà  ordered the flooding of mine to extinguish the fire, assuming there were no survives. He took responsibility and resigned from the Ministry.
Immediately thereafter, he went to Manchuria again to work at Anshan Iron & Steel Works. On 24th October 1929 (Showa 4), while he had studied on surface mining with Oxyliquit at Dagushan Iron Mine near Anshan, he was involved in the huge explosion accident which resulted in 36 victims. Fortunately, he got off with minor injuries. In 1933, he was assigned as the managing director and acting president. In 1939, he clashed with the headquarter of the South Manchuria Railway on the production plan, and he abandoned all his work at Manchuria and went back to Japan.
In 1940, Hidesaburà  was appointed to the board member of Showa Mining Co.Ltd., which later promoted him to the president in 1944. After the end of WWII, in 1946, he was invited to become the president of Dowa Mining Co. Ltd., and he held the position until 1963. In 1956, he submitted a dissertation on mining to Tohoku University, and took a doctorate of engineering.
On 22nd September 1970, he died by Pneumonia at St. Luke's International Hospital in Tokyo. Five days later, his funeral was held at Tsukiji Hongan-ji as the official ceremony of the Scout Association of Japan. He was posthumously awarded the Order of the Sacred Treasure.
As noted above, his elder brother and father-in-law were enthusiastic Boy Scout advocates.
Hidesaburà  himself became a Scout leader in 1916, and participated in the 2nd World Scout Jamboree in Denmark in 1924. He also participated in the organization of the 5th Nippon Jamboree in 1970 in Asagiri Plateau, Shizuoka Prefecture.
Kurushima related an anecdote about two soldiers during the Pacific War to visiting American Scouts in Japan. After a terrible battle, an American Marine was wounded in the jungle. He saw a Japanese soldier approaching with his bayonet, but he was so weak that he collapsed and lost consciousness, certain to be killed. When he awoke, he was surprised to find his wounds bandaged and a little note written in Japanese near him. The marine was rescued and transported to a field hospital, where he showed the paper to the doctor and asked him to translate. The note said that the Japanese soldier had approached the marine to kill him, but when the marine fell he did the Scout salute, and as the Japanese soldier had also been a Scout, they were brother Scouts. The Japanese soldier could not kill the marine, instead he bandaged the marine's wounds, finally wishing him good luck and goodbye.
In 1967, Kurushima was awarded the 43rd Bronze Wolf, the only distinction of the World Organization of the Scout Movement, awarded by the World Scout Committee for exceptional services to world Scouting, at the 21st World Scout Conference. In 1959 he also received the highest distinction of the Scout Association of Japan, the Golden Pheasant Award.
Since he was resigned from works in Manchuria before the Pacific war, he was exempt from the purge after WWII. As a result, he was given many public positions, including a chairman of the Japan Mining Industry Association, a chairman of the Union of Japanese Scientists and Engineers, and a board member of the Japanese National Railways.
In 1953, he worked at Yugoslavia as mining instructor of the United Nations. He had visited the country twelve times. In 1968, on the last trip to Yugoslavia in his life, Josip Broz Tito invited him to Brijuni.
