thumb|Hisayoshi Takeda was a Japanese botanist whose father was the British diplomat Sir Ernest Satow. He was a founder of the Japanese Natural History Society, and is known for his campaign to preserve the environment at Oze, which is now Oze National Park.[1]
Takeda was born in Tokyo Prefecture, the second son of Satow and his common-law wife, Takeda Kane. He learned English at the Tokyo Foreign Language School before going to the United Kingdom in 1910 to study botany at Kew Gardens in London. Takeda returned home in 1913 before returning to England in 1915 to continue his studies at the University of Birmingham. A year later he visited the island of Shikotan to conduct plant research as part of his doctorate. In 1916 he became a lecturer at Kyoto University before joining Hokkaido University in 1920. From 1928 to 1939, he returned to Kyoto University where he served as a senior lecturer.
Between 1948 and 1951, Takeda served as the sixth Chairman of the Japanese Alpine Club, which was founded in 1905. He was also the chairman of Nature Conservation Society of Japan until 1970, when he was awarded the Prince Chichibu Memorial Science Prize for his contributions to botany.
Through his research, he campaigned for greater protection of mountain plant species. Takeda, who is known as the "father of Oze", helped establish Oze National Park. The area covers part of Fukushima, Tochigi, Gunma and Niigata Prefectures in Japan. A memorial hall was built in his honor at Hinoemata, Fukushima Prefecture.
Takeda was married and had two daughters. He died aged 89 on June 7, 1972.
