His name is Kato Hachiro. He was born in Dewa province, present Yamagata pref. as the Third son of Izumi (No)
Kami Kunihide in 1798. He studied under Suishinshi Masahide. Kato Tsunahide, known as
its excellent Toran-ba hamon was Tsunatoshi’s elder brother. Tsunehide moved to
Osaka from Edo and learned under Suzuki Harukuni. After that Tsunahide went to
Kyushu Island and forged sword at Kumamoto. Around 1823, he lived a house of the
Uesugi family at Azabu in Edo.
He passed away in 1863, aged 66.
From Aoi Art: The first generation Chounsai Tsunatoshi is quite a good swordsmith
and is often compared to Koyama Munetsugu.
Koyama Munetsugu has a unique blade pattern, but Tsunatoshi works on various works
and skillfully manufactures Doranba hamon.
This work is a quite rearl that has never been seen before, and the Jigane is well-crafted
Jigane with a copy of an old sword.
Since it is a very rare work, I would definitely recommend it.
