Commentary

 

This is a shinogi-zukuri tachi with an ihorimune, and the widths at the moto and saki are not very different. It is slightly thick, there is a slightly large sori, and a chu-kissaki. The jihada is ko-itame mixed with itame and mokume, and the entire jihada is fine and slightly visible. There are ji-nie, chikei, and midare-utsuri. The hamon is mainly kaku (square)-gunome, mixed with kataochi-gunome, ko-gunome and togariba, and the entire hamon is a wide midare hamon. There are ko-ashi, a little yo, and a nioiguchi type habuchi (hamon boundary). The boshi is midarekomi, the omote is a yakizume style, and the ura has a komaru. The horimono on the omote and the ura are bo-hi, but on the omote it is carved through the nakago, and on the ura it is finnished with a kaku-dome. The nakago is o-suriage, the tip is a shallow kurijiri, and the yasurime on the omote are kiri, while the ura has slightly deep katte-sagari (new) yasurimei and the the original yasurime style is not visible. There are three mekugi-ana, two of them are closed, and this is a mumei katana.

Osafune Motomitsu is famous, and worked at the same time as Tomomitsu, who we introduced in the last issue. He supposed to be a Kanemitsu school smith or Kanemitsufs son. He used the gSabyoeh title and one example is a tachi mei signed Bizen kuni ju Osafune Sabyoe Motomitsu which was the 21st blade classified as Juyo token . We recognize his earliest dated blade as being from Koei 2 (1343) and the last one is Eiwa 2 (1376). His shapes are usually large, which reflects his active periodfs characteristic shapes, and they are not different from other smiths working at the same time. But his jihada are not as refined as his teacher Kanemitsufs and are visible. His hamon are based on, or mainly on, Tomomitsufs specialty notare type hamon. Beside this, many of his hamon are primarily gunome. On this sword, there is a kataochi gunome hamon mixed with all kinds of hamon shapes such as saka-ashi, square gunome, ko-notare and togariba. They are not simple, and extremely variable, and this is his characterictic hamon.

This katana is o-suriage mumei, and was judged as Motomitsufs work by Honnami Mitsutada and has a kinzogan (gold wire) inlay. The thickness is a little large for the width, and similar to the next generationfs Oei period shape. This kind of shape is seen around the latter half of the Nanbokucho period, and this is the same period as Motomitsufs career. His hamon are based mainly on square shaped features which are seen often in his work, and also are mixed with several other elements, such as kataochi gunome, and this judgement is quite natural. But the jihada is different from his usual work, and the entire jihada is fine and visible, but is a well forged ko-itame hada, and in particular, the midare utsuri is clear and this is one of his best works.

In Bizen work, those which are mainly based on kaku-gunome hamon were created by Nagamitsu (especially in his tanto), and Motomitsufs time is at the end of this type of style. Looking at the Bizen hamon transition, he is in an important position.

In Showa 23, this katana was classified as Juyo Bijutsuhin, the owner was Dr, Honma Kunzanfs younger brother Honma Yusuke who established the Honma museum in Sakata city, Yamagata prefecture.      

This katana is currently being shown in the NBTHK as part of the special exhibit gBizen Token O-koku (kingdom)h. The second period, from Nanbokucho to Muromachi times is on display from August 25th to November 1st. The exhibit will travel on November 29 to the Sano museum in Shizuoka, and then to the Bizen Osafune Token Museum in Okayama.

Correction and apology:

 

In the September issue, in the Meito Kansho, we described an o-tachi over 4 shaku long, classified as Juyo Bunkazai. Unfortunately, this was an error and the sword is classified as Kokuho. We apologize to the Futarasan shrine, the  owner of the tachi, and at the same time, we wish to correct this mistake.

 

 

 

 

 

No.705 Tosogu Kanshou

Juyo Tosogu (Important Tosogu)

 

Hisago karakusa-mon (gourd and karakusa design) tsuba

Mei: Nobuie

 

The two best master smiths working with iron tsuba are Kaneie in Kyoto and Nobuie in Owari. Kaneie chose scenery and people for his themes, and used a takabori (high relief) technique to develop his own style. Nobuie used a kebori (engraving with very fine lines) technique for letters, animals, and plant themes and showed a dynamic strong feeling in his work. Kaneiefs jitetsu feels moist and rich, and shows an elevated elegance. Nobuiefs jitestu has a feeling if dynamism.

This is a hisago karakusa pattern design with unique kebori work. The design is free, bold, and carefully done. A hyotan (gourd) has been used as a symbol for good luck since early times and Nobuie often used it as a theme in his tsuba. Beside this, Nobuie produced all kinds of kebori work such as letters and patterns, and they are majestic with a powerful design and his unique jimon (surface pattern), and excellent work. Also, his amazing tsuba shape and finished edge is the best of Nobuiefs characteristic points, and no one followed his impressive style.

Nobuiefs original tsuba shapes and powerful jitetsu display the ironfs spirit, and at  the same time you can feel a sense of mortality. The tsuba still exhibits some bushifs (warrior) spirit, and this is an excellent master work.

Teirei Kanshou Kai For September

 

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

Meeting Date: September 12, 2015 (2nd Saturday of September) at 1:00 pm.

Place: Token Hakubutsukan auditorium

Lecturer: Ishii Akira

 

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: katana

 

Mumei: Fukuoka Ichimonji

 

Length: slightly less than 2 shaku 2 sun 

Sori: 5.5 bu

Style: shinogi-zukuri

Mune: ihorimune

Jihada: ko-itame hada mixed with itame and mokume, and the entire jihada is tight. There are ji-nie and midare-utsuri.

Hamon: choji-midare hamon mixed with ko-gunome and togariba, and the entire hamon is high with an active midare hamon. There are frequent ashi and yo, a nioiguchi, a little ko-nie, some kinsuji, and some muneyaki.  

Boshi: shallow notare-komi with a komaru.

 

The katana hamon is recognizable at first glance and is mainly choji, and is a gorgeous midare hamon. The jihada has also midare utsuri, and from this, you can judge this as Bizen Ichimonji work. But the boshi is not midare, but a gentle notare hamon, and the shinogi ji has a nagare masame hada, and from these details, a few people voted for the Shinshinto Ishido schoolfs top smith Hioki Mitsuhira. Looking at this carefully, the nioiguchifs width has wide and narrow variations, and a very soft look, and the hamon shape is more variable, and for Mitsuhira this is obviously too classical and natural. If it were Ishido school work, the nioiguchi would be tighter, there would not be as much ashi and yo in the active midare hamon, and usually there are not much hataraki inside of the hamon, when compared to this katana.

Considering the boshi, many Ichimonji signed works have alterations in the midare hamon, but sometimes there are still gently shaped boshi. Considering the shinogi jifs masame hada, in the case of Shinto work, one sees a tighter jihada and a more regular pattern.

The katana has some muneyaki, and there is a Juyo Bunkazai tachi signed ichi, which is owned by the Hie shrine, and it has muneyaki which is more prominent than this one. 

 

 

 

Kantei To No. 2: wakizashi

 

Mei: Hashu junin Gassan Chikanori

    Eisho 9 nen 2 gatsu kichijitsu

 

Length: slightly over 1 shaku 9 sun 2 bu

Sori: slightly over 5 bu

Design: shinogi zukuri

Mune: marumune

Jihada: itame mixed with nagare and mokume hada; some parts are ayasugi hada, and the entire jihada is well forged. There are ji-nie, chikei, and whitish utsuri.

Hamon: narrow suguha mixed with a some ko-gunome. There are ko-ashi, ko-nie, and nijuba.

Boshi: straight yakiba with a o-maru and return; there are nijuba.

 

Chikanori was a part of the important Gassan smith group, and opinions are that that he was Hikobyoei Sukesadafs sutudent. His jihada are strongly forged when compared with the usual Gassan work. His hamon, besides suguha, are based mainly on an open valley choji midare hamon. His jihada and hamon are sophisticated and almost look like Sue Bizen work. His nakago tip shape is not as narrow as his schoolfs usual work and he is a special smith among the Gassan school.

O-shu Gassan smiths, as their name indicates, used to live the foot of Gassan, one of Dewafs three mountains which were known as a destination to where people made a pilgimmages. They are supposed to have likely been monks and traveled all over the mountain side to visit ashrams. From this it is supposed that they had communications over  a large area. Gassan Hiroyasu has a blade signed Nichu-ju. From this, we can conclude that some smiths moved to Hyuga and Satsuma. We have to consider that the Gassan and Naminohira smiths are related to each other, and some details in their styles are similar.

This blade has an unusual o-kissaki, it is less than 2 shaku long which is a short length, and the tip has sori, and from the shape, you can look at this as a mid- to late Muromachi period wakizashi. The jihada is itame, the nagare hada is prominent, in some places there is a little ayasugi hada, and the entire jihada is soft looking. The hamonfs nijuba is prominent, and also there is a wide shinogiji, a high shinogi line, and there are Yamato characteristic points seen as well.

Considering the marumune, this is a Kyushu work, and Satsuma Naminohirafs better work seems to the most appropriate answer, and about half of the people voted for Muromachi period Naminohira or Gassan. From the marumune, shape of the o-kissaki, and the suguha hamon, some people voted for Nanbokucho period Aoe work. But Aoefs shapes are different, their utsuri is not whitish but are dan-utsuri, and both the jihada and hamon are more clear and sophiscated.

Also, from the well defined narrow suguha hamon with prominent nijuba, some people voted for Sudo Kunitsugu in Kishu, and we treated that as a correct answer. From style of the hamon, it is understandable answer. However, Kunitsugufs jihada have more masame hada. This was from Tani Senjofs collection, who was famous military man from Tosa prefecture, and active from the  Bakumatsu to Meiji periods.   

      

 

 

Kantei To No 3: katana

 

Mei: Fuyuhiro saku

 

Length: 2 shaku 3 sun 8 bu

Sori: 8.5 bu

Style: shinogi zukuri

Mune: ihorimune

Jihada: itame mixed with mokume and o-itame, and the hada is visible. There are ji-nie, chikei, and a dark color jihada.

Hamon: there is a short yakidashi at the moto, and above this, a wide suguha; some places have a ko-notare hamon and ko-gunome. There are ashi and yo, ko-nie, and kinsuji; on the omote side there are tobiyaki and yubashiri; on the ura side there are prominent muneyaki.

Boshi: there is a wide yakiba which is almost ichimai; it is straight and a yakizume style.

 

This katana has large sori, and the sori on the upper half is a clear and prominent saki-zori, and the yakiba in the boshi is very wide, and from these characteristics, you can judge this as work from around the end of the Muromachi period or Sue koto work. Looking at the jihada, the itame hada pattern is a slightly large size, the hada is visible, there is a lack of refined forging, and a dark color jihada, and from this, you can recognize Northern area characteristic points.

This is a Fuyuhiro katana. The sword book gMeikanh listed 21 Fuyuhiro names in eight provinces such as Wakasa in the west, as well as Bizen, Bichu and Bingo. Today, from the signatures, obviously Fuyuhiro is not one sword smith. Because of this, Fuyuhiro styles show a wide variation, such as hitatsura, o-notare, Sue Seki, Sue Bizen, and this Takada style, and this type of work based on a suguha style is one of his styles. It is hard to judge just from the hamon style. This is a balanced suguha style, and on the omote there are tobiyaki and yubashiri. The ura has uneven muneyaki, and these unnatural hataraki stand out, and are different from traditional hataraki. Thus, we have to say that when compared with mainstream work, this has less sophistication. Also, Fuyuhirofs work sometimes has a narrow yakidashi at the moto, just like this katana. This is one of Fuyuhirofs characteristic points with his characteristic jihada. In talking about the yakidashi, you can imagine it was done after the beginning of the Shinto period. But in the Koto period, there are yakidashi styles, such as Nosadafs among the Seki smiths, and the Senju school. Considering the period, the Fuyuhiro name was recognized and more than half of the people gave a correct answer in the second vote.      

 

 

Kantei To No 4: tachi

 

Mei: Soshu ju Tsunahiro

    Tenbun 17 nen Tsuchinoe Saru 2 gatsu pi

   

Length: slightly over 2 shaku 5 sun 7 bu 

Sori: 8 bu

Design: shinogi zukuri

Mune: mitsumune

Jihada: itame mixed with mokume; some places have nagarehada, and some hada is visible.

Hamon: narrow suguha, mixed with ko-gunome. There are ko-ashi, a nioiguchi, and some uneven ko-nie.

Boshi: straight and and with an omaru. the ura is kuichigaiba.

Horimono: On the omote and ura are bo-hi with marudome. Under the hi on the omote there are bonji, gomabashi, and rendai. The ura has bonji and a So style kurikara. These are kasane-bori horimono (or different horimono).

 

This is a Soshu Tsunahiro tachi dated Tenbun 17 nen (1549). Usually his signed blades are short uchigatana or long hirazukuri wakizashi. They usually have prominent tobiyaki and muneyaki with a hitatsura hamon. It is rare to see a tachi with a suguha hamon by Tsunahiro. This could be some generalfs chumon-uchi sword (a special order). Possibly he promised to make a suguha hamon initially and then he forged more blades like this. The itame pattern is not as large as usual, and it is relatively well forged. It is hard to judge too much just from a suguha hamon and so it is important to find other key points.

Concerning the shape, since it is a tachi, the sori is a little too small, and instead, the sori at the tip is emphasized. The curve from the moto to the saki is too prominent, and from these details, it is usually hard to say something is Kamakura period work. Also the mitsumune middle surface along with the habakimoto is too narrow for the shape, and from this, it is a possibility that this is Muromachi period work. Looking at it more carefully, from the gentle suguha hamon, there is an imbalance with the muneyaki in the upper half. The horimono on the omote and ura are kasane-bori (independent) which is seen in many in Soshu Den works, and you can recognize the So Kurikara style horimonofs sanko style tsuka, the tip of the tsuka is a hexagon rather than the usual circle. From these characteristics, it is possible that you can judge this as Sue Bizen work.

Another opinion was this was the work of Heianjo Nagayoshi who has some suguha work and is known for good horimono. His Kurikara sanko tsuka are the same shape and a similar style, but in his case, most of them are single horimono, and not kasanebori or several independent horimono. His jihada are ko-itame which are more tight and have a more refined jihada. His hamon have a bright nioiguchi, and many of them are more sophisticated and refined. In his kurikara horimono the ken has a shallow curve, and more volume is seen, and these are major characteristic points.         

 

 

 

Kantei To No. 5: tachi

 

Mei: ? ? Osafune ju Motoshige

 

Length: 2 shaku 3 sun 1 bu

Sori: 7.5 bu

Design: shinogi zukuri

Mune: ihorimune

Jihada: itame hada mixed with nagare and mokume hada; hada is barely visible and some places have jifu. There are ji-nie, chikei and midare-utsuri.

Hamon: ko-gunome mixed with square shaped gunome, ko-choji, and ko-midare. There are frequent ashi and yo, and entire hamon has saka-ashi; there is a dense nioiguchi, frequent dense nie, and some places have kinsuji.

Boshi: straightens at the yokote, and above this, it is suguha. The tip is sharp.

Horimono: on the omote and the ura are bo-hi with marudome.

 

This tachifs funbari is obviously gone, and you can recognize it as suriage. The width is standard, and the widths at the moto and saki are not very different. The tip has sori, there is a chu-kissaki, and there are indistinct midare-utsuri, and from these characteristics, you can judge this as work from Bizen around the late Kamakura period.

The jihada pattern is a little uneven, and it is itame mixed with nagare, and the hada is a little soft, and some parts of the hada pattern are visible. There are jifu areas, and from these characteristics, it is appropriate to judge this as being from a non-mainstream Osafune school smith. Saka-ashi type hamon is seen in this period from Osafune smiths. Some parts of the hamon have slightly long square shaped gunome, and the boshifs tip is sharp, and these are Motoshigefs characteristic points. But compared with his usual work, this hamon is a classic style. There are fine ha-nie along the edge of the hamon, and there are dense nie inside of the hamon, and from this some people judged this as Ko-Bizen work. But there is sori at the tip, characteristically shaped, dark utsuri, and saka-ashi, and usually these characteristics are not seen except in Yukihidefs work.

Some peoplefs opinion was that the tachifs characteristic nie style is similar to another sunnobi (long or oversize) wakizashi classified as Juyo-Bunkazai. This is supposed to be one of Motoshigefs styles. 

Comparing details from the work of the smiths who received votes, Chikakagefs nie is not strong as this; if it were Kanemitsu, his jigane are more refined and better; if it were Unji, his shapes are wazori and his boshi are round with a return, and there would be Aoe style dan-utsuri above the hamon and fine utsuri. Along the shinogi there are midare-utsuri, and these details are different from Motoshigefs work.       

  

 

 

 

Shijo Kantei To No 703 (in the August, 2015 issue)

The answer for the Shijo Kantei To No. 703 in the August

issue is a katana by Kurihara Nobuhide dated Keio 2 nen (1866).

 

This is a wide, long blade, and the widths at the moto and saki are almost the same. There is a shallow sori with an o-kissaki and you see this kind of shape often in the Shinshinto period. Among these shinshinto, with a low hiraniku and a poor fukura shape are the Yamaura schoolfs characteristic shape made by their smiths such as Kiyomaro, Saneo, Nobuhide, Kiyondo and Masao.

The jihada is itame mixed with nagare hada, and the hada is visible. There are dense ji-nie, frequent chikei, and a strongly forged hada. The hamon has square large gunome, and at the top of the hamon these are mixed with ko-gunome, ko-choji, and form a midare hamon. Between the each gunome in some places, there are choji.

There are frequent ko-nie, and some very bright rough nie, and frequent kinsuji and sunagashi. From this strong characteristic style, most people voted for Nobuhide, and for an almost correct anwer, a few people voted for Kiyomaro, Masao, and Kiyondo.

Nobuhidefs teacher Kiyomarofs work around the Tenpo and Koka periods have characteristics such as: many of them have a gunome midare hamon mixed with prominent choji; the distance between the midare hamon waves is small; and there are frequent kinsuji and sunagashi. Around the Kaei period, his midare hamon no longer have prominent choji, and the entire hamon is a large gunome midare hamon, and the kinsuji and sunagashi hataraki are more gentle.

Kiyomaro passed way in Kaei 7 (1854), two of his students faithfully followed Kiyomarofs Kaei style, and one is Minamoto Masao who was Kiyomarofs student who became independent around Kaei 6 (1853). The other is Saito Kiyondo, who become a student of Kiyomaro in Kaei 5 (1852) and who stayed with him until he passed way.

Nobuhide was developing his own style around Kaei 5 (1852). His unique square shape hamon are different from those of Kiyomaro, Masao, and Kiyondo, and has more individuality. In Nobuhidefs early work around the Kaei period, the square features in the hamon are not so prominent square, and his hamon are not too  similar to his teacher Kiyomarofs. The hamon have smaller size gunome and a more gentle appearance.

Later, in the Ansei and Manei periods, Nobuhidefs style become more individualized with a strong and unique appearance.We suppose that the change in his style may have followed his teacherfs death, and developed right after he became independent.
