Daimon Suketake served as a bushō during the Sengoku period. He was a retainer of the Mibu and Shimotsuke-Utsunomiya clans. Suketake founded the Daimon, an illegitimate branch of the Mibu clan. He was the lord of Murai Castle in Shimotsuke Province.
Suketake was born as the third son of Mibu Tsunashige. Under another theory, he was the third son of Mibu Tsunafusa.
As a member of the Mibu clan, Suketake ranked as one of the senior retainers. Accompanying the advance of the Mibu into Kanuma, Suketake was appointed as the lord of Murai Castle located in-between Kanuma and Mibu as a means to control and secure the road connecting Kanuma and Mibu. Around this time, he adopted the Daimon surname.
There is a letter from the Tenbun era (1532 to 1555) in which Suketake requested prayers from the Sōchi clan who were priests at the Ise Grand Shrine. In this letter, he is referred to under the court title of Saemon-no-jō and had already completed his coming-of-age ceremony.
In an account by Sōchō, a renga master, noted that his son, Mumago, is the type of person who would be widely successful.
