Aoi Art’s Comment: Dr. Honma Kunzan, a renowned authority on Japanese swords, introduced many masterpieces to Dr. Compton in America.
It is said that Dr. Compton possessed numerous superb swords.
After his passing, these famous swords were auctioned in three separate events.
For instance, an Ichimonji Tachi fetched 62 million yen, while a Sukezane Tachi was sold for 55.3 million yen.
Dr. Compton is also known for rediscovering the National Treasure Bizen Saburo Kunitomo at Terukuni Shrine in Kagoshima, which had gone missing after the war. He returned it to Japan without compensation and returned many other Important Cultural Properties, for which he was awarded the Order of the Sacred Treasure, First Class, by the Emperor.
This sword, by Mutsu no Kami Tachibana Tameyasu, was a treasured heirloom of the Naito family, the Osaka Castle Guardians.
A friend of mine acquired it at auction and has carefully preserved it, but due to aging, it is now being offered for sale.
Please consider purchasing this valuable piece from Dr. Compton’s collection.
