The first and second generations of the Akasaka school, Tadamasa and his son, moved to Edo around the Kan'ei era, where they produced tsuba by adding ingenuity to the Owari-tou method and the Kyo-tou method, and prospered until the end of the Edo period. The 1st, 2nd and 3rd generation (Ko-Akasaka) have good forging of the iron base, and many of them are round and thick with round ears. From around the time of Tadatsuki IV, the tsuba became a little thinner and became more elaborately crafted. The name Akasaka was used from the place where the craftsmen of this family lived (present-day Akasaka area in Minato Ward, Tokyo).
Akasaka School Tadatoki Hikojuro is the fourth generation from the Akasaka School's first generation Tadamasa, but he was the first generation of the Akasaka School to have a name, and from then on, the name Tadatoki was used until the ninth generation.
In 1707, he succeeded the third Masatora and served for 39 years. In his later years, he handed over the headship of his family to the second generation Tadatoki, who took the name Tadamune. He died in 1746.His style has become somewhat thinner and more elaborate than that of Tadamasa first.He makes Ji-Sukashi-Tsuba with designs such as Syatou, paulownia, thin, Chasen, Suehiro, and Myoga in Tetsuji Marugata.
