Special feature: Chounsai Tsunatoshi is the third son of Izumi Kami Kunihide, and his father was Kato Tsunahide, who were from Yamagata prefecture and very good at Toranba. He was born in Kansei 10(1798), from Dewa. He was originally named Kato Hachiro, and sometimes called himself as Kore toshi. He studied under Suishinshi Masahide and named himself as “Chounsai”. He served Uesugi family in Yonezawa clan. He moved to Edo and moved back to Osaka. After studying sword making at Suzuki Harukuni, he wandered in the west. He stayed in Kumamoto prefecture. In Ansei 3(1856), his Chounsai was succeeded to his son Koretoshi and Tsunatoshi the 2nd, and changed his Mei to Chojusai. From Ansei 6(1823), he started to live in Uesugi family house, and passed away in Bunkyu 3(1863) at the age of 66. His nephew is Ishido Korekazu the 7rd, and he had great pupils like Koyama Munetsugu, Takahanashi Naganobu, Seiryuken Moritoshi etc, and there is no doubt that he built one of the greatest school of Nihonto in the late Edo period.

From Aoi Art: Chounsai Tsunatoshi and Koyama Munetsugu made similar Hamon. On one hand, Tsunatoshi made Hamon whose upper part splits into two, and whose Boshi is Midarekomi. On the other hand, Munetsugu made round-shaped Boshi and round-shaped Hamon. Both swordsmiths flourished in the late Edo period and they are similarly famous. Besides, Toranba was already popular in the Edo period and many swordsmiths like Tsunahide, Ozaki Suketaka, and Chounsai Tsunatoshi tried to make it. We believe that it had to be a big pleasure to succeed with making Toranba.
