1. 奉 台命 明治聖帝御佩刀影打
2. 帝室技藝真 月山貞一 時?成彫同作
3. 聖崇萬歳 明治亥年 普生吉祥日
4. 寶作無窮 以大和傳精錬之
1. First part indicates a dedication. 2nd part is supposed to mean that the sword was worn by Emperor Meiji.
2. Made by Gassan Sadaichi, member Imperial Court Artist. Engravings also by the artist (some misspelled kanji)
3. Emperor, Banzai. Meiji year of the boar*. A lucky day in ? (should be a month, but it makes no sense)
4. Unquestioned Treasure Made in the Yamato tradition.
"year of the boar" is vague without knowing the zodiac stem (which all such dates use). The "Imperial Court Artist" system came after 1880s, so presumably this would be 1899 or 1911.
Horribly fake.
