Hello! I'm new to the site.  I've been collecting swords and antique weapons for several years. I practice traditional Kenjustsu; laido & kendo.  Friend of mine sent me photo of his sword's tang with a very long kanji. I think the sword is an early WWII officers sword.  (I can get a full photo if needed.) Really appreciate any help in translating.  There's disagreement among us here, and I've tried translating the individual kanji using an app, but I cannot seem to get a read on it. Tha
