Thank you very much, Mr. Ekholm! Your examples are greatly helpful, especially that TH to Juyo one!

Ah, 惜っしい! The last Kanji is 門/Kado/door, so this is 関吉田兼門 Seki Yoshida Kanekado.

Thank you, Hoshi San! I was briefly in 1st place, then Mr. Ekholm took over. At least we finally know who the Indecisive Ninja was! I must say that this system of offering 5 potential options is even more helpful than the usual Nyusatsu Kantei "hints". If they were in the classic Nyusatsu Kantei system, where I myself have to give a precise answer, then most of the Kantei quizzes I did today would be impossible for a very green dum-dum like me (who only knows the biggest names in Nihonto, and throwing the answer "Kotetsu" to any Edo Shinto with a suddenly wide Yaki under the Yokote I see in Kantei. ←True story when I was reading 刀剣鑑定のきめ手), like 小反義次 or 綾小路宗延 (I was like, "Huh? Who dis?"), or even just all the different and countless smiths from the school of Sa. I am still passionately waiting for a dedicated Kantei Q&A post so we can finally discuss how to tell a Sa Yukihiro from a Sa Hiroyasu, a Jitsua from Sairen, or just rant about that one signed Hoki Sadatsuna without Kuromi/Shirake, Yakiotoshi, or most of other Hoki traits, and looking absolutely like a Ko-Bizen. 50 questions in Ranked in one day is too much......

Perhaps the original 関鍛冶累代の系譜.

Of course! Here it is. This is from 関鍛冶累代の系譜, so it is only received tradition. From this paragraph, it seems that this was passed down for generations among Seki smiths, later donated to Haruhi Shrine by Ujifusa, and taken out by Kanefusa to give to Oda Nobutada, lord of Gifu, to understand who is who in the Seki smiths. This is dated in Keian (1648) in the end. (Also, I think it says whoever leaked this document to anyone outside the Ujifusa family will be punished by Gods, so......)

Great game! Is there any chance for a Japanese version of the description in the future...? Also, and this is only my wild fantasy, but wouldn't it be awesome if there were a post where people could discuss this Kantei game (the day after, so it's not spoiling anything), like a crowdsourced Kantei comment explaining the thought process!

Hi! I think this is all the text about Sadahiro in Owari Tōkōfu. The quality of Oshigata is very limited.

Hi! This looks like 紀宗房 明珍 Ki Munefusa Myochin.

Hi! I think this is 古備前正恒 地刃典型 傑作ノ一 刃長弐寸四尺四分二厘有之 昭和乙巳年葉(?)月於久我山房 薫山誌（花押） Ko-Bizen Masatsune, classic/typical Jiba(Jigane and Hamon), one of his masterpieces, Hacho/length at 2 Sun 4 Syaku 4 Fun 2 Rin (70.72cm), 8th(?) month, 1965, at (his) house in Kugayama, recorded by Kunzan (Kao) I'm not sure if the 8th month is correct...

Thank you, Mr. Rohan! I was under the impression that NBTHK would not change their attribution when upgrading to a higher paper, but I guess I was too naive. I was also not aware of that Tamatsugu-Masamune upgrade instance. Very interesting!

I was talking with my Nihonto friends, and this topic came up. Was there an example, or did I just dream it I know there was a 7th TJ Den Shizu that was previously a Juyo Naoe Shizu, but were there TH examples? Thank you all for your help!

Hi! This is signed 豊後住藤原行長 Bungo Ju Fujiwara Yukinaga. I'm not sure if the signature is genuine.

Hi! This looks like 福地宗近 Fukuchi Munechika, literally Munechika in a place of good luck, not really a known smith. This is no earlier than Shinshinto, and likely a low-end one. Edited: Sorry! I was wrong, this is the known Gunto smith 福地鋭雄 Fukuchi Toshio.

I was doing a Kasyu Kanewaka special because I've failed every Kanewaka Kantei quiz I've seen since forever, and I found this...? When I clicked and entered Seiyudo by Katana 24, a referral was automatically added to my HTML address. This is consistent with other shops. Naturally I tried with NihontoWatch, and this did not happen. So...... Also there are so many Kanewaka I'm losing it And this is the quiz that got me. A Saka-Choji Kanbun Shinto, hint is that this smith is also good at Hako-Midare. According to Kanzan Sensei's Token Kantei Notebook, Saka-Choji in Shinto are mostly from Fukuoka Ishido, Kisyu Ishido, and (2nd gen) Kasyu Kanewaka, Kanewaka being the only one doing Hako-Midare as well. Eh, makes sense.

Missed this one from Showa Meibutsu Cho.
