It is believed to be a rare treasure from the Muromachi period, spanning the ancient sword era of the Northern and Southern Dynasties. The tang, with significant polish removal, exudes a very antiquated elegance, making it irresistibly charming to fans of ancient swords. Although there are some scratches and black rust that seem to be from the sharpening during the Pacific War era, there are no flaws like chips, bends, or cracks in the blade edge, and it doesn't hinder its appreciation in its current state. Upon first glance, what appears as fine scratches all over the ji (surface of the blade) is not abrasion or damage. Instead, it is the distinctive forging pattern, known as "slag", characteristic of Maikusa and Houju. It looks like a large, white river flowing along the hada (grain pattern of the steel), and is considered one of the major highlights of Maikusa and Houju swords. It comes with a copper habaki with silver cross. It is housed in the highest quality beautiful Army-designated military sword mountings, with no play or looseness, and the lock is firm. The guard's accompanying accessories are all intact, and the scabbard has no scratches, nearly resembling a new one with its gloss. It is a post-war registration with a four-digit Tokyo noble registration. [Sword Registration Certificate] Registration symbol number: Tokyo Kyō No. 8496 (March 22, 1951).
