Commentary

 

This is a shinogi-zukuri tachi with an ihorimune, a standardl width, and the widths at the moto and saki are different. It is slightly thick and long, and there is a prominent large koshizori with funbari. The tip has uchizori and there is a short chu-kissaki which appears as a small kissaki. The jihada is itame mixed with mokume hada, and is well forged. On the ura side there is a fine koitame hada. There are ji-nie, chikei, and the entire jihada appears moist (guruoih) and there are jifu utsuri. The hamon is komidare mixed with ko-choji and ko-gunome. There are frequent ashi and yo, dense thick ha-nie, some kinsuji, and at the koshimoto mizukage shaped utsuri is clear, and it almost looks like part of the hamon. Some parts of the hamon appear soft. The boshi is straight, a little kuichigai, with a komaru and a return. The horimono on the omote and the ura are bo-hi with kaku-dome. The nakago is ubu, the tip is a shallow kurijiri, and the yasurime are katte-sagari. There are two mekugi-ana, and on the omote under the second mekugi-ana, there is a large two kanji signature almost on the center, which was made with a thick chisel.

There are many Ko-Bizen smithsf blades available with signatures and which are recognized in meikan sword books. Tomonari and Masatsune are examples and Toshitsune is one of these. He has more than ten signed blades today. there is one Juyo Bunkazai (owned by the Kyoto National Museum), Juyo Bijutsuhin, and ten Juyo Token classified blades. In the meikan, his works are listed during the Shogen (1207-11), Bunreki (1234-5), and Kencho (1249-56) periods, but his active period has not yet been completely and definitively determined. His signature use the gtsuneh kanji and are only two kanji long, and there are no long kanji signatures, the same as seen with Masatsune. His signatures are located under the mekugi-ana and almost on the center of the nakago, and from this he is thought to be one of the Masasune school smiths. His work are in the Ko-Bizen style, and show either a ko-midare hamon mixed with ko-choji and ko-gunome, or a suguha style hamon mixed with ko-midare. Most of his hamon have frequent dense nie, frequent kinsuji and sunagashi.

Among Toshitsunefs signed tachi, this is well done, in good condion, and could be one of his best works. This is over 2 shaku 5 sun long length, but the upper halffs sori is slightly uchizori, and from this characteristic shape, there is an elegant feeling and this reflects the periodfs character. The itame hada is refined, and on the ura side the ko-itamehada is very fine, and the entire jihada is well forged, and there are clear jifu-utsuri.

This tachifs utsuri are strong, and almost look like a yakiba, and in the same period in Bizen there are several examples similar to this such as Masatsunefs Juyo Bunkazai tachi owned by the NBTHK, a Yoshikane classified as Juyo Bunkazai and owned by the Hayashibara museum, and a Tadashige classified as Tokubetsu Juyo.

There are abundant hataraki such as ashi, yo, and kinsuji. As a Ko-Bizen work, the ko-choji and ko-gunome in the hamon are somewhat prominent. This has a classic hamon showing good technique and this is supposed to be an important characteristic in judging the period.

Just looking at the tachi, you can recognized Toshitsunefs high level of skill, and details such as the large nikuoki, the healthy shape, and espescially the ubu nakogo are very valuable. This is one of the tachi shown in the gKozan oshigatah book.

This tachi is being shown in our special exhibit gBizen Token O-koku (The great kingdom of Bizen Swords)h with the first period shown being from the Heian to Kamakura periods. This is at the NBTHK from June 9th to August 23rd. On November 29, the exhibit travels to the Sano museum in Shizuoka prefecture, and after this it will travel to the Bizen Osafune Token hakubutsukan.

No.702 Tosogu kanshou

 

Yatsuhashi (a theme from the story Ise Monogatari) sukashi tsuba

Mumei, Heianjo style sukashi tsuba

 

From the mid-Muromachi to mid-Edo period, we see Heianjo-sukashi or Kyo-sukashi tsuba. These are iron sukashi tsuba, with sophisticated unique designs, and detailed carving. From the sophistated designs, they should have been made around the Kyoto area, and the name comes from there. Older period work is called Heianjo sukashi, and later work is called Kyo-sukashi.

Heianjo and Kyo-sukashi tsuba were made at almost the same time as Owari sukashi tuba. Owari sukashi tsuba have dynamic designs, and are heavy iron sukashi tsuba. Heianjo Kyo-sukashi tsuba are a little thin, the ground or surface is flat, there is a large open sukashi base, and the patternfs lines show fine details, with a very delicate and elegant feeling. These two styles show large contrasts.

This tsuba is a good example of Heianjo sukashi work, showing a part of the classic story gIse Monogatarih, or gYatsuhashih. Usually, the Yatsuhashi theme uses kakitsubata (iris), but sometimes there are no kakitsubata, just moving water, clouds, and karigame ( wild geese) design elements, as we see on this tsuba. The ground shows large open or sukashi areas, narrow designs elements, and the entire composition is well balanced, and shows a refined feeling. Compared with the same schoolfs work, the iron is excellent, and the area above the seppa-dai is a little narrow compared with the area below, and the hitsu-ana are long vertical shapes, from these characteristics, the tsuba is from the older period, and can be judged as Heianjo sukashi work.

Teirei Kanshou Kai For June

 

The swords discussed below were shown in the June 2015, meeting at the NBTHK headquarters building. This discussion presents answers concerning the makers of these blades.

Meeting Date: June 13, 2015 (2nd Saturday of June) at 1:00pm.

Place: Token Hakubutsukan auditorium

Lecturer: Imoto Yuuki

 

During these meetings, five swords are displayed for examination. The blades can be examined, but the nakago are covered and cannot be seen (they are left in the shira-saya tsuka). After examining the 5 swords, the meeting attendees must decide who they think made the 5 swords which were available for examination, and submit a paper ballot with these names. The 5 swords seen in the January meeting are described below, and the correct names of the makers are presented, along with an explanation of important details which should lead a person to pick the correct sword smithfs name.

 

 

Kantei To No. 1: tachi

 

Mei: Nagamitsu

Length: 2 shaku 2 sun 7 bu

Sori: 8.5 bu

Style: shinogi-zukuri

Mune: ihorimune

Jihada: itame hada mixed with mokume hada; the entire jihada is well forged and tight. There are dense ji-nie, chikei, and midare-utsuri.

Hamon: choji mixed with kawazoka-choji, fukuro-choji, gunome, ko-gunome, and togariba, There are frequent ashi, and yo, and a nioiguchi; some places have nie; on the omote there are some tobiyaki and kinsuji and a bright nioiguchi. 

Boshi: small midarekomi, tip are sharp,and short return.

Horimono: the omote and ura have bohi; the omote has a marudome and on the ura the hi is carved through the nakago.

 

This is a Juyo Bijutsuhin Nagamitsu tachi. It is a little wide, annd the widths at the moto and saki are not very different. Although it is suriage, there is still a large koshizori, and the tip also has sori, and there is a chu-kissaki. This is a typical mid- Kamakura period dynamic shape.

The tachi hamon on the omote is mainly based on gunome, and the ura hamon based mainly on choji which is an unusual style. People recognized the ura sidefs gorgeous choji hamon with the dynamic shape, and many people voted for a Fukuoka Ichimonji smith.

But if it were by a Fukuoka Ichimonji smith such as Yoshifusa, Sukezane, and Norifusa, the hamon on the omote and ura would contain more choji, and an a very active midare hamon. Yosifusafs hamon with narrow waist fukuro-choji are prominent. Norifusafs hamon are mixed with saka-ashi and are narrow.

Looking at the choji hamon carefully, the hamon is mixed with kawazuko-choji with a narrow waist, and also forms a midare hamon. Norifusa has many gunome hamon, and around the monouchi the hamon becomes gentle. From this characteristic hamon, it is possible to narrow down possible smithfs names to smiths such as Osafune Mitsutada, Hatakeda Moriie and gorgeous hamon work by Nagamitsu.

This tachi is Nagamitsufs early work and follows his father Mitsutadafs gorgeous choji midare hamon example (on the ura side), and many people voted for Mitsutada.  But the omote side hamon is mixed with more gunome, and some places show a continuous hamon, and round top hamon features, and this is a characteristic Nagamitsu hamon. Also, Moriie has work similar to this this, but if it were his work, many of his jihada are visible.         

 

 

Kantei To No. 2: katana

 

Mei: Kaou Shinyu Kujirai gimi Katsuyoshi Yono Yushi ni me wo tome

Katsute Benrei wo ukeru

Yueni ima ittou wo tukurite kougi no man-ichi wo shasu  Naokatsu

Murasame Katsuyoshi na Jitsuan shosu

Free translation: To my best friend Kujirai Katsuyoshi for responsibly educating my child. As a small token of my appreciation, I am presenting him with this katana  Naokatsu

Murasame (sword's name or meibutsu): "Katsuyoshi Jitsuan shosu" accompanied with a kokuiniengraved kao)

 

Length: 2 shaku 4 sun 9.5 bu  

Sori: slightly less 7 bu

Design: shinogi zukuri

Mune: ihorimune

Jihada: tight itamehada; the hada is barely visible. There are dense ji-nie, and frequent fine chikei.

Hamon: gunome mixed with ko-notare, choji, and togariba. There are dense nie, some uneven and small tobiyaki, frequent kinsuji, and long sunagashi, and a bright nioiguchi.

Boshi: midarekomi with hakikake; on the omote there are togari and a komaru; the ura is yakizume.

 

Suishinshi Masahidefs theories and ideas were adopted by his student Taikei Naotane, and were transmitted to Naotanefs students. One of Naotanefs top students was Jiro Taro Naokatsu. This tachi is in the Soshu Den style established by Naotane, and then followed by Naokatsu.

This is a wide blade, and the widths at the moto and saki are not very different. There is a poor hiraniku with a long kissaki, and this is a heavy katana. From these charcteristics, not many people missed the Shinshinto period. The jihada is itame, the hada is visible, the hamon has frequent nie, kinsuji and sunagashi, and from these characteristics, many people voted for in Shinshinto period Soshu Den smiths, especially Kiyomaro and his schoolfs smiths.

The hamon has frequent nie, the entire hamon has kinsuji and sunasgashi, the boshi tip is sharp and has a return, and from this, at first impression it looks like the Kiyomaro school. If it were Kiyomaro school work, the hiraniku would be smaller and poor, the kissaki more slender, and there would be a sharp feeling in the shape. Also, the Kiyomaro schoolfs jihada are itame mixed with mokume and nagarehada, and they are well forged. Kiyomarofs hamon around the Tenpo and Koka periods have gunome mixed with choji, and between the midare waves, the hamon peaks are close to each other and there are vertical alterations. Around the Kaei period, Kiyomarofs midare hamon choji are not prominent, and the entire hamon is composed primarily of large size gunome. In the same school, Nobuhidefs hamon are large square shaped gunome mixed with ko-choji, ko-togari, ko-gunome, and is a characteristically intricate rough midare hamon.

This katana does not have these characteristics, and people voted for Kiyomaro school the first time, but many of them corrected themselves in the second vote and voted for the Naotane school, which used to specialize in Soshu Den as well as Bizen Den. This was a good judgement.

Also, this katana does not have strong characteristic points to use to judge an individual smithfs name, so Naotane and his schoolfs smiths are treated as almost correct answers.

Other answer were Shinshinto Satsuma smiths such as Motohira and Masayoshi. Their blades have more ha-niku, the opposite of a katana shape, and their jihada and hamon have prominent uneven ara-nie.     

 

            

       

Kantei To No 3: tachi

 

Mumei: Bishu Osafune Tomomitsu

 

Length: slightly over 2 shaku 4 sun 1 bu

Sori: slightly over 8 bu

Style: shinogi zukuri

Mune: ihorimune

Jihada: itame mixed with mokume hada; the entire jihada is tight, and there are dense ji-nie, frequent chikei, clear midare utsuri and a bright jigane.

Hamon: kataochi gunome mixed with gunome, kaku-gunome, choji, togari, and there are some sakaashi. There are ashi, yo, a nioiguchi, some nie, and some kinsuji .

Boshi: midarekomi; the omote side has small togari, and the ura side is based on togari.

Horimono: the omote and ura have bo-hi with marudome, and under the hi on the omote side is a bonji with a gyo style kurikara; the ura side has three bonji with a suken. 

 

This is a Tomomitsu tachi, recently classified as Tokubetsu Juyo Token. The sword book gKokon Meizukushih listed Tomomitsufs work as being very similar to Kanemitsufs work. Also, in this book, he was listed in the the school as the most skilled smith.

This is a wide blade, and the widths at the moto and saki are not very different. It is thin with an o-kissaki which is a mid-Nambokucho period shape. The jihada is itame mixed mokume, and the entire jihada is tight, and there is a bright jigane with clear midare utsuri. The hamon is mainly kataochi gunome mixed with kaku-gunome, the boshif tip is sharp, and there is a return. From these characteristics most people voted for Kanemitsu and his schoolfs smiths.

Kanemitsu has three students. First was Tomomitsu, and he was supposed to be either Kanemitsufs younger brother or his son; the pther students were Motomitsu and Masamitsu. They all carried on their teacher Kanemitsufs style. Many of Tomomitsufs hamon are based on notare and Motomitsufs hamon are a kataochi-gunome style. Among the three students, the youngest is Masamitsu, and usually many of his shapes are more gentle than the peak Nambokucho shape, and his hamon are narrower and close to the Kosori style.

Looking at this tachi carefully, notice that the hamon is based on kataochi gunome mixed with all kinds of structures such as kaku-gunome, choji, saka-ashi gunome, and togari, and the entire hamon has vertical alterations, and this kind of hamon is seen often in Motomitsufs work.

This kind of work by Tomomitsu tells us, that besides making his own style hamon, he worked in other styles, and this is a good example. If you look at this as Kanemitsu school work, it is enough. In particular, Motomitsu is a good judgement and his work is close to Tomomitsufs, and so his name is treated as an almost correct answer at this time.

The other answer was for the branch school smith Motoshige. If it were his work, the jihada would have nagarehada, the hada would be visible, and his hamon contain wide kaku-gunome somewhere.                

 

 

 

Kantei To No 4: kotachi

 

Mei: Bishu Osafune Yorimitsu

    ? toku 2 nen 2 gatsu pi

 

Length: 1 shaku 9 sun 2 bu 

Sori: slightly over 7 bu

Design: shinogi zukuri

Mune: ihorimune

Jihada: itamehada mixed with frequent mokumehada; there is some nagarehada, and the entire jihada is visible. There are ji-nie, frequent thick kawari-tetsu type chikei, pale straight utsuri and a slightly dark jihada.

Hamon: gunome, mixed with ko-notare, togari, kaku-gunome, and kataochi-gunome. There are ashi, yo, a nioiguchi, some ko-nie, fine sunagashi, and at the koshimoto there is some kinsuji.

Boshi: midarekomi; the tip is komaru, and there is a short return.

Horimono: the omote and ura have bo-hi with marudome, and under this a bonji inkoku horimono. 

 

The Kosori school, at the end of the Nambokucho period in the Bizen area referred to smiths who did not belong to the mainstream Bizen schools. The mainstream smiths were Kanemitsu and branch school smiths such as Motoshige, Chogi, and Morikage. Beside these, other smiths whose school affiliations were not clear are called Kosori smiths.

It is not known where the Kosori name came from. There is a theory that the name derived from many small sized tachi, just like this kotachi. Beside kotachi, sometimes there are blades over 2 shaku 4 sun long, and many of the widths are either standard or a little wide, the widths at the moto and saki are different, tip has sori, and the kissaki is either a chu-kissaki of a long chu-kissaki.

Many of the jihada are itame mixed with mokume and nagarehada, and the hada is visible. The entire jihada not too refined and soft appearing. There are different colored jifu, different types of iron chikei, and a type of unique forging. There are many styles of hamon: ko-notare mixed with gunome, kataochi-gunome, kaku-gunome, small ball-like gunome hamon which are continuous like Yoshii work, ko-notare mixed with ko-gunome, ko-togari, square shapes, kataochi gunome, and intricate midare hamon. These hamon are diverse, but are narrow hamon for the mihaba, or a small size, and this is a characteristic point.

This kotachi shows these characteristic points well, but all Kosori works are similar, and it is difficult to judge individual names. Some people voted for Hidemitsu and Moromitsu, but if you judged this as a Kosori smithfs work, we treated that as a correct answer at this time.

Possibly because of the small size, many people voted for Eikyo (1429-1440) Bizen smiths such as Norimitsu and Sukemitsu. But if it were Eikyo Bizen smith work, many of the jihada are tight, and we almost never see this much unrefined jihada.                   

 

 

 

Kantei To No. 5: katana

 

Mei: Higo no kami Tachibana Yoshitsugu saku

Kiritsuke-mei: San-no-ma otoshi hiraji-iri

             Nochi ryokuruma otoshi hiraji-iri

             Matanochi wakige otoshi hiraji-iri

 

Length: 2 shaku 4 sun 5.5 bu

Sori: 5.5 bu

Design: shinogi zukuri

Mune: ihorimune

Jihada: tight ko-itame; there are thick dense ji-nie, and frequent chikei.

Hamon: based on a wide suguha and mixed with gunome and ko-notare. There are frequent ashi and yo, a dense nioiguchi, thick nie, some nie-suji and a bright nioiguchi.

Boshi: small midarekomi with strong hakikake, a round tip and a return.

Horimono: on the omote and the ura are bo-hi carved through the nakago.

 

This is a Edo Hojoji school Higo no Kami Yoshitsugu katana. There is a Yoshitsugu wakizashi that Yamano Kanjuro Hisahide donated to the Shiogama shrine. From the wakizashi signature g Hongoku (native) Hitachih, Yoshitsugu is known to have come from there. Also, in Genroku 5 (1692) he is supposed to have moved to Kagoshima, and there is a Satsuma-uchi blade, signed and stating he is 66 years old.

This is a wide blade and the widths at the moto and saki are different. There is a chu-kissaki and a slighty large sori which falls within the Kanbun-shinto shape. The hamon is based on a wide suguha mixed with gunome and it has a juzuba (string of beads) form. There is a dense nioiguchi and dense nie. From these characteristics, besides Yoshitugu, many people voted for Kotetsu, Okimasa, Kazusa no suke Kaneshige and Edo Hojoji school smiths.

Many smiths whose active period was during the Kambun to Empo periods have shapes that have a shallow sori, like a Kanbun-shinto shape. If this were Kotetsufs work, the jihada and hamon would be clearer, his boshi are gunome at a yokote, and then straight, with a komaru tip and return which is called Kotetsu boshi. Kazusa no kami Kaneshigefs hamon in some places show several continuous or fused gunome.

The Edo Hojoji school smithsf hamon, except for Yoshitsugu, are primarily a mid-suguha style with continuous gunome, and the entire hamon does not show much vertical alteration. They are also a small or narrow suguha style hamon. Okimasa was active at almost the same time, and he has blades with larger sori. However,  his hamon are a juzuba style with prominent continuous gunome or with two fused gunome waves, and many of them have yubashiri, rough ha-nie, and more dynamic hataraki.

Yoshitsugufs hamon characteristics have each gunome with a clear shape and a midare hamon, and this is different from the Edo Hojoji schoolfs usual small or narrow hamon. He has a large sori and this seems to arise from the time he was working. Also, he has blades which often show mixed ara-nie, kinsuji, sunagashi, and prominent imozuru and may be an influence from his time in Satsuma. The katana shows his characteristic features.               

 

 

 

 

 

Shijo Kantei To No 700 (in the 2015 May issue)

The answer for the Shijo Kantei To No. 700 in the May

issue is a wakizashi by Dewa Daijo Kunimichi.

 

The wakizashi is wide, long, thick, and has a slightly large sori, and from the shape you can judge this as Keicho Shinto work.

Dewa Daijo Kunimichifs signed blades show up from Keicho 13 (1608) to the dated work in Kanbun 2 (1662). For 55 years, his active time spanned the Keicho Shinto to the Kanbun Shinto periods.

From this, in his work, his shapes can show a Keicho Shinto shape, a Kanbun to Shoho period Shinto shape, and have standard widths with a chu-kissaki which is close to a Kanbun Shinto shape.

Many of Kunimichifs jihada are itame mixed with mokume, and the entire hada is visible. There are dense ji-nie, frequent chikei, the Horikawa schoolfs unique rough forging, and the hints refer to this. At the same time, often his jihada on the hamon side show some nagarehada and masame hada, and this is one of his characteristic points.

He produced all kinds of styles. In particular, his hamon can be based on a large size midare hamon with gunome, vertical alterations, and a dynamic gorgeous midare. There are ashi, yo, some saka-ashi, a dense nioiguchi, abundant nie, frequent kinsuji and sunagashi, and this wakizashi shows a good example of his characteristic hamon. We could say this is the best of his examples with this kind of hamon in a Keicho Shinto shape, with dynamic and detailed work. Most of time the boshi are a shallow notare with a sharp tip and return, which is a Sanpin style, and this is a one of his characteristic points.

Kunimichifs nakago tips have a pronounced kurijiri; his yasurime are osuji-chigai, and although he makes Keicho Shinto blade styles, we often seen kesho style yasurime in his work.

His signatures are often long on the omote side in the center, and are not completely straight. His work often is dated too.

This is a typical Kunimichi work, and most people voted for the correct answer.
