Looks like a low quality edo period katana

It this looks like Yamashiro no kami Kunikiyo(山城守国清). However, the kiku mon was misplaced in the wrong order. It should be curved at the other side of the tang.

OfCourse. See this...The shortcomings of materials can be compensated by craftsmanship

I beg to disagree with this statement. The signature is Sanjyou Munechika(三条宗近). The 1st gen Sanjyou Munechika is a very famous swordsmith in Heian era. However, this name was used by countless swordsmith of Sanjyou school from Heian era to Meiji era. Also, later gen Sanjyou Munechika did curve signature on the blade.

I think his location is within US

Many swordsmiths prefer to use old province name rather than use modern name.

First one：服部正廣（Hattori Masahiro） Second one：Not 中國, but 越中國（Etsu-chuu no kuni）. Can't recognize other words.

This part it incorrect. 第十代 肥後宇土藩主-10th generation Lord of the Uto Domain in Higo 第十一代 肥後 熊本藩主-11th generation Lord of the Kumamoto Domain in Higo 細川斉護公– Lord Hosokawa Narimori Hosokawa Narimori was 10th generation Lord of the Uto Domain before 1826. After 1826, he inherited his uncle's domain and became the 11th generation Lord of the Kumamoto Domain. 細川藩家老 賜六千石 抱刀工鍛冶 - Chief retainer of the Hosokawa， received a fief yielding 6,000 koku of rice， official swordsmith Numata Naomune was chief retainer and official swordsmith of the Kumamoto Domain(in fact, swordsmith is his "part-time job", he is first and foremost a politician) There's no mention of anyone being invited or anything being ordered. And Fifth photo：古鞘破損書写 This is written because the old saya is broken

Not sure how to translate word for word. This sword is a gift from Numata Naomune, the chief retainer and official swordsmith of Kumamoto Domain（received a fief yielding 6,000 koku of rice）, to his lord Hosokawa Narimori, the 11th gen lord of Kumamoto Domain(also the 10th gen lord of Uto Domain). It seems that you get a sword once belonged to a daimyo！

Sold!

Looks like Sue Bizen to me. Also, It's a long shot, but it could be Taira-Takada.

Mino school, obviously

Who is Okamoto Kazumune? I haven't heard this name.

That's not how the kanji is written. Even kindergarteners can write much better than this. Maybe it is made by an illiterate person.

Seki or Showa stamp only means the sword passed the Army's examination, nothing more. It has nothing to do with whether the sword is made by traditional way or not.

Sold!

So how could they see it is Morishige?
