Kotaro Yoshida (1883-1966) was born in Fukushima Prefecture, Japan. He graduated from Tohoku Gakuin in Sendai in 1906, and was also a graduate of Waseda University and an American university.
He was a writer, jounalist, and author of many books.
Kotaro began his study of Daito-Ryu Aikijujutsu under Sokaku Takeda in 1915, and introduced Morihei Ueshiba, the founder of aikido, to Sokaku Takeda in Hokkaido.
He received the Kyuju Dairi award from Takeda and often accompanied him as an assistant instructor. After the war he taught in Tokyo.
Kotaro Yoshida taught Richard Kim, a well-known karateka in San Francisco and Mas Oyama of Kyokushinkai Karate. He also taught Katsuyuki Kondo briefly in the early 1960s.
He was skilled in martial arts from a young age, because both of his parents were trained. He survived many combat situations and killed many adversaries, including the person responsible for killing his father.
He was highly intelligent and mastered many related arts like zen, meditation, breath control, ki development, intuition, etc.
Yoshida was paralyzed in his later years, after saving a child from being run over. He moved to Ibaragi Prefecture, Japan and continued teaching, where he died in 1966.
His son, Kenji Yoshida, lived for many years in the United States and taught Yanagi-Ryu Aikijujutsu to Don Angier, who teaches in California.
Morihei Ueshiba developed the martial art of Aikido from his combat studies of Daito-ryu Aikijujutsu with Sokaku Takeda, and his spiritual studies with the Omoto Kyo and Onisaburi Deguchi.
Aikido focuses on harmony and non-resistance, leading to Success
Don Angier was born in 1933, and is a well-known American martial artist who is head of the Yanagi Ryu Aiki Ju Jitsu system.
He inherited the title of Soke from Kenji Yoshida, the son of Kotaro, a local handyman under whom Angier studied as a teenager.
I personally have an Aiki Principles video in my martial arts collection that features Master Don Angier... he is a very impressive martial arts expert with truly unique skills.
Apart from the traditional Aikijujutsu art, he also teaches students how to generate an irresistable power through deep relaxation. It is a great resource of valuable information for Aikido students that I recommend!
The study of the aiki arts is a fascinating subject. There are many great masters that offer great training tips to develop real skill - More Here
