Examination of Important Swords
Length: 2 shaku 3 sun 6 bu (71.5 cm)
Sori: 9 bu 8 rin (2.95 cm)
Motohaba: 8 bu 6 rin (2.6 cm)
Sakihaba: 5 bu 3 rin (1.6 cm)
Motokasane: 2 bu 2 rin (0.65 cm)
Sakikasane: 1 bu 2 rin (0.35 cm)
Kissaki length: 7 bu 9 rin (2.4 cm)
Nakago length: 6 sun 4 bu 9 rin (19.65 cm)
Nakago sori: slight
This is a shinogi zukuri tachi with an ihorimune, and the widths at the moto and saki are not very different. There is a large koshizori, the tip has sori, and there is a small kissaki. The jihada is ko-itame mixed with itame and mokume hada and the entire jihada is well forged. There are ji-nie, a little bit of chikei and jifu utsuri. The hamon is a wide suguha type mixed with ko-gunome,ko-midare and ko-choji. Notably on the omote around the monouchi there is a midare hamon, and there are small tobiyaki, and yubashiri. The entire hamon has frequent ashi, yo, and fine nie. The boshi is straight with a komaru, and on the omote there are small hakikake. The nakago is ubu, the tip is a shallow kurijiri, and the yasurime are a shallow kattesagari. There is one mekugi-ana. On the omote under the mekugiana along the center, there is a two kanji signature.
Masatsune is famous as one of the two best Ko-Bizen smiths along with Tomonari. Both of them have a reasonable number of extant blades with signatures. Comparing their work, in the category of elegant tachi shapes, Tomonari is better. In the category of well forged and refined jihada, Masatsune is better. Tomonariüfs hamon are natural appearing and not artificial appearing, and with his characteristic tachi shape, his works have a classic look. Masatsuneüfs work is more skillful and many of them are sophisticated looking. Comparing their different signatures we see that sometimes Tomonari has a long signature such as ügBizen kuni Tomonariüh, and Masamune has only two kanji signatures. The Ko-Bizen smiths such as Masatsune, Sanatsune, Toshitsune, Kanehira, Yoshikane, Kunitsugu, and Yukihide all made similar dynamic tachi shapes. Of course sometimes they made elegant tachi shapes too. Tomonari has a tachi classified as Juyo Bunkazai dated during the Katei period (1235-38). There is a theory that Masatune has a third or higher than third generation signatures, and it is possible the later smiths were active after the early Kamakura period. This tachi has a slightly narrow mihaba and a large sori for Masatsuneüfs work and a small kissaki, and shows an elegant shape. The jihada is a tight well forged ko-itame hada, with his characteristic moist appearing refined jihada, and there are clear jifu utsuri. The hamon is a wide suguha, and the width covers almost half of the ji and has a small midare wave pattern. There are ashi, yo, and abundant hataraki. The boshi is clean and straight, round and with a return. The entire jihada and hamon are bright and clear. This is a better than his usual work, and fully shows Masamuneüfs characteristics, and is excellent work. In Masatsuneüfs ügtsuneüh kanji, the left side has two types of styles. Conventionally, the formal style kanji signatures have a more classic appearance. This signature is in formal style kanji, but this is not a classic appearing mei, and this is a notable point. The monouchi area shows part of the smithüfs characteristics. In the Edo period,this was owned by the Echizen Maruoka clanüfs Arima family. They were Christian daimyo and Arima Harunobuüfs family sent young boys on a mission to the Pope in Rome in Tensho 10 (1582).

Botan zu (picture of peonies) fuchi kashira
Mei : Hashimoto Ittshi with kao
The great master goldsmith Goto Ichijo, in the second half of the Edo period, had many master smith students, such as Funada Ittkin, Hashimoto Ittshi, Nakagawa Ittsho, Wada Ittshin and Araki Tomei, and the school was very prosperous. Hashimoto Ittshi studied for 16 years under Ichijo. In the Kaei period (1848-1853) with Ichijoüfs permission, Ittshi became independent, and with another artist named Yushusha, he moved from Kyoto to Edo following Ichijo who was the shogunüfs okakae smith, and Ittshi worked with Ichijoüfs collaborators there. He was supposed to have been Ichijoüfs close aide and collaborator. Later he moved back to Kyoto, and produced many masterworks. After the Meiji periodüfs Haitorei edict, he gave up his engraving work, the same as other goldsmiths. Occasionally he is supposed to have had a tabi business. However, he started working again as a goldsmith, and in Meiji 10 (1877) at the first Naikoku Kangyo Hakurankai (an expoposition started by Ookubo Toshimichi ) he displayed his work. After that, he worked for the Imperial Household Agency and received many prizes and honors. He passed away in Meiji 29, at the age of 77. Among the goldsmith schools, he followed most closely his teacher Ichijoüfs styles, materials, carving style, and themes. Usually, his works are very elegant with gentle carving. But this fuchi and kashira are a takaniku-bori botan with a full volume which is unusual for him. The botanüfs petals look like they are just opening, and full of life and dynamic. Maybe this was a special order or his original creation, but in either case, this is an elaborate work which displays his skill.

Length: 8 sun 4 bu (25.4 cm)
Sori: almost none
Motohaba: slightly over 8 bu (2. 45 cm)
Motokasane: 2 bu (0.6 cm)
Nakago length: 3 sun 1.5 bu (9.54 cm)

This is a hira-zukuri tanto with a mitsumune. The width is little large for the length, it is thick, and there is almost no sori. The jihada is a tight ko-itame, there are thick dense ji-nie, fine chikei, a unique jihada for the school, and clear nie-utsuri. The hamon and boshi are as seen in the picture, and some parts of the hamon have yubashiri, ko-ashi, a slightly wide nioiguchi, dense nie, kinsuji and fine sunagashi. The hamon is bright and clear. The horimono on the omote and ura are katana hi with tsure-hi carved through the nakago. The nakago is ubu. The nakago tip is kurijiri and there is one mekugi-ana.

Teirei Kanshou Kai For April
The swords discussed below were shown in the April 12, 2014, meeting at the NBTHK headquarters building. This discussion presents answers concerning the makers of these blades.
Meeting Date: April 12, 2014 (2nd Saturday of April)
Place: Token Hakubutsukan auditorium
Lecturer: Ishii Akira
Kantei To No. 1: katana
Mumei: Izumi no kami Kanesada saku
Length: slightly over 2 shaku 3 sun 1 bu
Sori: 7 bu
Jihada: itame mixed with nagare hada in some places. There are dense thick ji-nie, chikei, and the bottom half has utsuri.
Hamon: gunome mixed with ko-gunome, yahazu gunome, and togari; the entire hamon is a high midare hamon. There are ashi, the hamon is almost nioi-deki, and there are some tobiyaki.
Boshi: on the omote side it starts as midarekomi, and becomes straight and has a komaru. On the ura side it is notare-komi, komaru, and the tip has small hakikake.
This katanaüfs length is standard, the tip has sori, and from the shape, you can judge this as a Muromachi period katana. It is clearly seen that the hamon has primarily individual gunome, and the top of the hamon elements are round, and some places have togariba. The entire yakiba is prominently high with up and down vertical alterations. Also, some places contain nagare hada, and from these characteristics, it is understandable this is latter half to late Muromachi period Seki work. Among Seki work, this is a refined jihada with almost no visible jihada; the hamon is even, the overall appearance is sophisticated, and you can recognize this as work with a high level of skill. Among the Sue-seki smiths, the most skilfull and the ones with the best reputations are called ügNosadaüh, and the name Izumi no kami Kanesada comes readily to mind, and in the voting, many people voted for him. Some people voted for Kanefusa and Kanemoto. If it were Kanefusa, narrow bottom gunome would be prominent and there would be more emphasis on vertical variations in the hamon. Also, he does not have many signed katana, and many of his works are either hira-zukuri sunobi wakizashi or tanto. Kanemotoüfs hamon are as you know, sanbonsugi-ba, which contains continuous groups of togariba type ko-gunome with three, four or five togariba. There is a low yakiba, and they are a different style. However, Kanesada has surprisingly many suguha beside this style. The other Kanesada hamon are mainly a notare Senshi style (Muramasa school style) which was the early Edo period smith Echigo no kami Kunitoshiüfs idealized style.
Kantei To No. 2: katana
Mei: Hizen kuni ju Mutsu no kami Tadayoshi
Length: 2 shaku 3 sun 4 bu
Sori: slightly less than 7 bu
Design: shinogi zukuri
Jihada: tight itame; there are thick dense ji-nie, and fine chikei.
Hamon: small yakidashi at the moto, and above it a choji type hamon mixed with gunome, square shaped gunome, and clusters of these midare hamon are contiguous with a suguha hamon. There are ashi, yo, a wide nioiguchi, frequent dense nie, yubashiri, tobiyaki, and on the omote side in the middle there is a small muneyaki.
Boshi: straight and with a komaru. The boshi return is long.
This is a Hizen Sandai (third generation) Tadayoshi katana. The boshi is straight with a komaru and a clean shape beside the midare hamon. The entire hamon has a fresh look, and from this I hope you can judge this as a Shinto or Shinshinto katana. The katana has the right length and sori, and has a well blanced shape. The jihada is a well forged ko-itame hada. The hamon contains groups of midare clusters and is continuous or connected from the moto to the tip by a low suguha hamon. In some parts in the valleys, the nioiguchiüfs width is wider, and along the entire hamon thre are dense waves of ko-nie, and from these characteristics, it is not difficult to judge this as a Hizen to. Notably the jihada and hamon are bright and clear and well made. Usually the hamon style is called ügShizu utsushiüh, and from this, naturally the first three generationüfs names are supposed to come to mind. Also, another detail which can narrow down the smith is the slightly wide mihaba, the thick shape, and the strong healthy shape. The ko-itame hada is tight and the hada is not visible. Look at the midare hamon carefully, there are a couple of different hamon themes there. The boshi return is long, and consideration of these characteristics will bring to mind the Sandai Tadayoshi. Some people look at the yakidashi at the moto, the refined jitetsu, and prominent choji hamon as important points, and they voted for the Osaka smiths Shodai Kunisuke and Shin Kunisada. The rank of the workmanship and the jihadaüfs judgement are fine. But if it were one of these smithüfs work, there would be a more prominent choji type hamon and a higher yakiba. The upper half, especially around the monouchi area, would have tobiyaki, yubashiri, or muneyaki. In particular, the Shodai Kunisukeüfs yakidashi gradually become wider.
Kantei To No 3: katana
Mei: Mumei Naoe Shizu
Length: 2 shaku 4 sun 2.5 bu
Sori: 4 bu
Style: shinogi zukuri
Jihada: itame mixed with mokume hada; the entire jihada is well forged, and along the hamon border, a strong nagare hada becomes a masame type of jihada. There are ji-nie, frequent chikei, and pale utsuri.
Hamon: ko-notare mixed with ko-gunome, togariba, gunome, and the entire hamon has a low yakiba. There are ashi, slightly uneven thick nie, and some places have niesuji, kinsuji, sunagshi, yubashiri, and tobiyaki.
Boshi: straight; on the omote it is maru (round), and on the ura komaru; on both sides the tips have hakikake.
Horimono: on the omote and the ura there are bo-hi carved through the nakago.
This katanaüfs original funbari is obviously gone. The sori is shallow for the length and there is a long kissaki. From the lengh, you can imagine this originally was a long katana. There is a well forged itame hada, and considering the variations of the hamon nioiguchi, nie, and hataraki, this should be Nambokucho period work. Also, from the prominent nagare hada, you can guess this Yamato school work. From Yamato, you can imagine this is Yamato-shizu, Mino-shizu, Naoe-shizu, or Kaneshige and Kaneyuki. Kaneshige and Kaneyukiüfs characteristic hamon do not have too high gunome or continuous small notare, and are a different style from this katana. If this were Yamato-shizu work (using a narrow interpretation of Kaneujiüfs work during his Yamato stay, or a broad interpretation for the smiths who remained in Yamato), the boshi would be large and round, the return short, and the kinsuji and sunagashi hataraki more prominent, and their hamon are a smaller midare hamon. So the last choice would be either Shizu or Naoe Shizu. If it were Shizu, their strong characteristic point is the omaru boshi shape which is obviously different and the kinsuji and sunagashi hataraki would be more prominent than on this katana.There are frequent thick nie, more frequent vertical alterations, and as an established Soshu Den group they will have a strong spirit. After these candidates are gone, and from the hamon which is mainly gunome and ko-gunome, the Naoe-Shizu name would be sufficient.
Kantei To No 4: katana
Mei: Nagasone Okisato Nyudo Kotetsu
Length: 2 shaku 3 sun 7 bu
Sori: 4. 5 bu
Design: shinogi zukuri
Jihada: tight ko-itame; there are thick dense ji-nie and frequent fine chikei.
Hamon: small yakidashi at the moto, and above this mainly ko-notare mixed with gunome; at the koshimoto the hamon crumbles and becomes a kuichigai type hamon; the entire hamon is high, and a continuous midare hamon. There are frequent ashi and yo, a dense nioiguchi, thick even ko-nie, and some places have kinsuji and sunagashi; in places there are nie-suji.
Boshi: yakikomi at the yokote (especially on the ura this is conspicuous); straight, and komaru. The omote side is a kuichigaiba style.
This katanaüfs widths at the moto and saki are a little different. There is a shallow sori, short chu-kissaki, and the shape has a dynamic robust feeling. The shinogi-jiüfs masame hada is conspicuous, and tight and fine, and from these chacteristics, you can judge this as Kanbun period work, and in particular, Edo Shinto work. The jihada has thick dense ji-nie, fine chikei, and a refined tight ko-itame. The hamon has a short yakidashi at the moto, and above it, a continuous midare hamaon without much vertical variation. Some places have thick ashi, a dense nioiguchi, and the ji and hamon are bright and clear. Also, the ura has a conspicuous yakikomi at the yokote, and one should pay attention to the visible jihada called ügteko tetsuüh. You can look at this as Hako-tora period Kotetsu work without misgivings. If it were early period Hane-tora work, there would be a long yakidashi, and the hamon style would be a primarily a mixture of one bunch of small and large gunome called ühHyotanbaüh, and the vertical variations would be prominent, and these characterisitcs are different. In voting, some people even mentioned this as ügHako-toraüh. If you look at the hamon closely, instead of gunome, it appears more like ko-notare. The mihaba is wide compared with Kotetsuüfs usual work and the hamon style is too small for the mihaba (or width of the blade). If you look down the entire hamon, from the moto to the saki you can recognize this as Juzuba. This katana shows his characteristic points very well, and most people voted for the correct answer in the first vote. As an almost correct answer, some people voted for Okimasa. If it were Okimasaüfs hamon, there are prominent rough nioiguchi with nie, his shapes are more likely to have a large sori, and the clarity of the jihada and hamon are not as good as Okisatoüfs. From the signature, this katana is supposed to have been made around Enpo 1 (1673).
Kantei To No. 5: wakizashi
Mei: Mumei Den Masamune
Length: slightly less 1 shaku 9 sun
Sori: slightly over 3 bu
Jihada: itame hada, and the entire jihada is well forged; some parts of the hada are visible. There thick dense ji-nie and pale utsuri.
Hamon: ko-notare mixed with gunome, ko-gunome, and ko-choji; the entire yakiba is a low midare and some parts are yakikuzure. There are frequent ashi and yo, a dense nioiguchi, small and large size thick uneven nie, kinsuji, nie-suji, frequent sunagashi, yubashiri and tobiyaki.
Boshi: midare-komi; the tips are nie-kuzure and with hakikake.
Horimono: on the omote and the ura there are futasuji-hi carved through the nakago.
Masamune is a great master smith in Japanese sword history. He is famous, not only in the sword world, but also with the general public. He established the artistic nie style of the Soshu Den school which descended from Kunimitsu and Yukimitsu. His active period is known to be at the end of the Kamakura period. This wakizashi has a standard width, and the widths at the moto and saki are not much different. There is a long chu-kissaki and the tip of the hi on the omote is low (judging from the usual location of the tip of the hi on the ura side, it appears that the sword may have been polished too much). From these characteristics, a number of people voted for the next generation of smiths in the Nambokucho period. In particular, from the futasuji hi, some people voted for Sadamune. If it were his work, even though he followed his teacherüfs style well, his hamon are based on either small or large shallow notare hamon patterns, or primarily, gunome and ko-gunome mixed in the hamon, and usually the entire hamon has a more gentle original style. Considering nie hataraki such as chikei, kinsuji, nie-suji, inazuma, tobiyaki, and yubashiri, Sadamuneüfs work does not exhibit as much of a dynamic feeling.
This is a Den Masamune wakizashi classified as Tokubetsu Juyo Token. Masamuneüfs styles are not only contain a lot of nie hataraki, the nioiguchi and the elements of the nie are completely in harmony: the nioiguchiüfs softness and shade, and the nieüfs large and small sizes, the strong and gentle appearance, and the nioiguchiüfs width all are in harmony. Masamune tried not to discipline or connect all of these elements in his swords. Dr.Honma Kunzan described his work with the word ügkyoüh (maniacal). His real ability is to use an endless range of styles just like sumie ink paintings (black and white brush pictures). This hamon has a lot of activity, and a dynamic style not afraid of failures. As I explained, you can see a lot of nie and nioiguchi hataraki.
Some similarly shaped blades have Meibutsu or names such as the ügTaro saku Masamuneüh classified as Kokuho and the Meibutsu ügIkeda Masamuneüh classified as Juyo Bunkazai. Looking at the futasuji-hi, there is similar carving in the Meibutsu ügOgaki Masamuneüh classified as Tokubetsu Juyo Token. From these facts and the hamon style, the identification of a work from Den Masamune is definite.
In the early Edo period, this was supposed to have been owned by the Tokugawa Bakufu ship bugyo (magistrate or commissioner) Mukai Shokan Tadakatsu who supervised warships, Bakufu ships, and patrols of the frontier.
Shijo Kantei To No 686 ( in the March, 2014 issue)
The answer for the Shijo Kantei To No. 686 in the March issue is a katana by the Nidai Echizen-no-kami Kanesada (Itakura Gonnoshin Terukane dojin: i.e. Itakura GonnoshinTerukane is another name used by Kanesada)
This katana has a standard width and the widths at the moto and saki are different. There is a shallow sori and a chu-kissaki, and from the shape, you can judge this as a Kanbun Shinto katana. In the Nidai Kanesadaüfs katana in this period, there are many long chu-kissaki instead of short chu-kissaki. For Shinto work, his styles often have poor hiraniku. Also, his mune have a noticeably sharp angle and this is one of his characteristic points. In the Shinto and Shinshinto periods, there are many smiths who worked with toran-midareba just like this katana, and each smith had a different characteristic style. In particular, the Nidai Kanesadaües toran has many unique characteristics. His toran midare are a clear katayama shape, and yahazu shape gunome appear in the hamon. Near the yokote, there are three continuous gunome. His tight ko-itame jihada, near the ha side, are sometimes mixed with nagare masame hada. Along with this jihada, there are prominent sunagashi. In voting, most people voted for the Nidai Kanesada. Besides him, a few people voted for Tsuda Echizen-no-kami Sukehiro. They have some common points: Sujehiro was also a Kanbun period Osaka Shinto smith, and worked in the Hato style which uses a breaking wave shaped hamon, toran-ba, and also midare hamon mixed with square shape gunome, and so the answer has understandable points. But in Sukehiroüfs toran we do not see often three continuous gunome under the yokote. His nakago have a unique koho shaped kesho-yasurime pattern. Sukehiroüfs toranüfs characteristic points are known as Hato style toran, which is a midare hamon mixed with square shaped gunome. His boshi start from a little under the yokote, the width of the hamon becomes wider and is continuous straight to the tip, with a komaru and return. He is famous as being the father of Toran midare, but to verify this, there are not yet enough detailed analysis or examples, and this issue should be studied more in the future.
