Notable Features: Sagami Koku Ju Yasuaki, a resident of Sagami Province, was born on January 10th in
Taisho 4 (1915) in Tochigi Prefecture. He later became known as a Yasu-mei (named)
swordsmith at the Yasukuni Shrine’s Japan Swordsmith Forge in Showa 12 (1937). In
Showa 19 (1944), he received the Yasuyoi (named) swordsmith title from the Minister of
the Army. After the war, he couldn’t practice swordsmithing for some time, but eventually
resumed his work when sword production was permitted. According to Tomu Kishida,
who wrote about Yasuyoi swords, it is said that he created more than 8,000 pieces
during his 12-year career.

Aoi Art’s Comment: This sword exhibits a deeply formed midare hamon with active nie, surpassing the works of Yasukuni Shrine swordsmith era. We proudly introduce this flawless and exceptional piece to all enthusiasts. What’s astonishing is the level of energy he put into his work while creating swords at Yasukuni Shrine.

Historical Context: This sword was created in Showa 51 (1976) after the end of the war.
Showa 50 (1975) was marked by the Rose Boom in Versailles, the fall of Saigon in the
Vietnam War, Queen Elizabeth’s first visit to Japan, and the passing of Prime Minister
Eisaku Sato. Japan was entering a new era of stability and progress.
