Shame on you, thats a steal, not in the holiday spirit I might add. You are lucky buyer of a "Yasukuni Jinga Sword" made by "Yasunori" . I have a few Yasukuni blades myself, very sought after among Japanese sword collectors especially of gendai blades (more recent handforged blades). The sword is in bad need of polish, and the tang could be in little better condition, but indeed a rare find. If you want to sell it let me know.
