In Chapter 12, Middle Kamakura Period: Tanto, it is described that the tanto shape called takenoko-zori appeared during the middle Kamakura period.  This type of tanto  curves slightly inward at the tip.  The drawing below may be somewhat exaggerated to show the curve.  The actual curvature of the takenoko-zori is not very noticeable.  Perhaps only a few millimeters inward. 

Usually, the length of a tanto is around 12 inches.  Tantos are categorized as follows: if it is approximately ten inches, it is called a josun tanto (定寸短刀), longer than ten inches is called a sun-nobi tanto (寸延び短刀), and shorter than ten inches is called a sun-zumari tanto (寸詰短刀).

During the Heian period, several swordsmith schools were active.  We use the word “den” to refer to these schools.  These include Yamashiro-den (山城伝), Yamato-den (大和伝), and Bizen-den (備前伝).  Additionally, the following regions had other active groups during the Heian period: Hoki-no-kuni (伯耆の国) and Oo-u (奥羽).   Oo-u is pronounced “Oh,” and “U” as in uber.

 Yamashiro Den (山城伝 )

During the Heian period, among Yamashiro-den swords, the most famous sword was the “Mikazuki Munechika“ (三日月宗近) by Sanjo Munechika (三条宗近).  Mikazuki means crescent.  It was named Mikazuki Munechika because the crescent-shaped uchinoke (collection of Nie) pattern appears in the hamon.  It has a graceful shape, a narrow body, koshi-zori, funbari, and a small kissaki.  The sword shows a wood grain pattern on its surface, with suguha with nie mixed with small irregular lines, and sometimes a nijyu-ha (double hamon: 二重刃) appears.  Sanjo Munechika lived in the Sanjo area of Kyoto.  His sword style was passed down through his sons and grandsons: Sanjo Yoshiie (三条吉家), Gojo Kanenaga (五条兼永), and Gojo Kuninaga (五条国永).  Gojo is also a district in Kyoto

Houki -no-Kuni (伯耆の国)

Houki-no-kuni is the area now called Tottori Prefecture.  It is known for producing high-quality iron.  The sword, “Doujigiri Yasutsuna” (童子切安綱), made by Hoki-no-yasutsuna (伯耆の安綱), was one of the most famous swords of its time.                                                                                                 

The characteristics of Yasutsuna’s sword ——- It has a graceful shape with a small kissaki, a narrow hamon (often suguha with ko-choji), coarse nie in the hamon area, and a large wood grain pattern mixed with masame on the ji-hada.  The hamon area often shows inazuma and kinsuji.  The boshi area is yakizume, and the kaen (pronounced ka as in calf, en as in engineer) has a slight turn back.

Bizen Den (備前伝 )

Bizen is in Okayama Prefecture today.  It is known for producing high-quality iron.  From the Heian period to the present, Bizen has been famous for its sword-making tradition.  The sword-making group in this area during the Heian period was called the Ko-bizen group.  The most famous swordsmiths in the Ko-bizen group included Bizen Tomonari (備前友成), Bizen Masatsune (備前正恒), and Bizen Kanehira (備前包平).                                                                   

Ko-bizen group’s characteristics ———- A graceful, narrow body, a small kissaki, and a narrow-tempered line with ko-choji (small irregular) with inazuma and kin-suji.  The ji-hada displays a small wood-grain pattern.

　　　Bizen Kanehira (備前包平)　Sano Museum Catalogue (佐野美術館図録)                          (Permission to use granted)

I saw Ko-bizen Sanetsune (真恒) at Mori Sensei’s house.  That was one of the kantei-to of that day.  I received a dozen*ᴵ.  The book written by Hon’ami Koson was used as our textbook.  Each time I saw a sword at Mori Sensei’s house, I recorded the date next to the swordsmith’s name in the book we used.  It was Nov. 22, 1970.  It had a narrow body line, a small kissaki (Ko-bizen komaru), kamasu*2 (no fukura), and suguha.  Kamasu is a condition in which the fukura (arc) is much less than usual.  Looking back, it is amazing that we had the opportunity to study such famous swords as our study materials.

Kantei-Kai

Kantei-kai is a study meeting.  Usually, several swords are displayed, with the nakago area covered.  Attendees try to guess the sword maker’s name and submit their answer sheets to the judge.  Below are the grades.

Atari —– If your answer is the exact correct name, you get Atari. That is the best answer.

Dozen —— The second best is a dozen.  It means nearly a correct answer. The subject sword was made by the family or clan of the right den.   A dozen is considered very good.  It indicates that the student has solid knowledge of the particular group.

Kaido Yoshi —– This means it is correct regarding the line, but not about the family.

Jidai Yoshi — it means the time or period is correct.  Each Kantei-kai has its own grading system.  Some may not have a “Jidai Yoshi” grade.

Hazure——– the wrong answer. 

Once all answer sheets are submitted, they are graded and returned. The judge reveals the correct answer and explains why.

*1 Dozen:  Almost the same as the correct answer. *2 Kamasu:  A name of a fish that has a narrow, pointed head.

0-timeline - size 24 BakumatsuThe red circle indicates the time we discuss in this section

The later part of the Edo period is called Bakumatsu.  See the circled area on the timeline above.  Swords made during this time are called shin shin-to.   They are also called Fukko-to (復古刀: revived sword).  Fukko-to replicates the shape, hamon, boshi, and other features of the Ko-to and Shin-to swords.  The characteristics of the Shin Shin-to (新々刀) and well-known swordsmiths are listed below.

The Characteristics of Shin Shin-to

  • Katana, wakizashi, and tanto all tend to resemble or imitate the ko-to and shin-to in shape.
  • Many swords often have a Hi or detailed engravings.
  • One swordsmith would create multiple sword styles, such as Soshu-den, Bizen-den, and Shin-to style.
  • Often shows Katai-ha.

30 katai-ha

                                                                  Katai-ha

  • Weak (not tight) Nioi.
  • Yakidashi (2 to 3 inches above machi) is often suguha(straight line hamon), even though the rest of the area has irregular    Boshi is often irregular midare.
  • Detailed engravings are more realistic than those from earlier times.

Well-known swordsmiths of Shin Shin-to

  • Settsu (Osaka area) ——————Gassan Sadayoshi (月山貞吉), Gassan Sadakazu (月山貞一). The Gassan family is known for their detailed carvings.
  • Musashi no Kuni (Tokyo area) ————-Suishinshi Masahide (水心子正秀),  Minamoto Kiyomaro (源 清麿),  Taikei Naotane (大慶直胤),  Taikei Yoshitane (大慶義胤).  Yoshitane is well-known for his carvings.

  • Satsuma (鹿児島: Kagoshima) ———— Oku Moptohira (奥元平) Namino Hira (波平)

Meiji Ishin-To

Right before the Meiji Restoration, long swords (about 3 feet) without any curvature were made.  Sa Yukihide (from the Tosa area) forged this type of sword.  Saigo Takamori (西郷隆盛) and Sakamoto Ryoma (坂本龍馬) owned such swords.  Both are well-known historical figures from the Meiji Restoration.  Both were part of the Kin’no-to (勤皇党) group, which supported the emperor and reformed the political system.

                            The red circle indicates the subject we discuss in this section

During the Shinto era, there were seven main prosperous regions where many swordsmiths gathered and actively forged swords.  These are Yamashiro (山城) in Kyoto, Settsu (摂津) in Osaka, Musashi (武蔵 ) in Edo, Hizen (肥前) in Saga, Satsuma (薩摩) in Kagoshima, Echizen (越前) in Fukui,  and Kaga (加賀) in Kanazawa.  Swordsmiths from each area shared common regional characteristics of their places.  Knowing each of these characteristics is the easiest way to understand Shin-to.  However, it is important to remember that each swordsmith within a group had their own unique way of sword-making.  The following are only general descriptions of these characteristics.

Below is a map of Japan.  Hokkaido is not shown on the map because swords were not made there during that time.

64Map with number with 8

1.  Yamashiro (山城) Kyoto

The Yamashiro shin-to sword has a solid and strong look.  The hamon near the lower part of the blade, just above the machi (区) area, shows suguha (straight hamon).  This is called kyo-yakidashi (京焼出し, meaning it starts with a straight hamon.  Then, it shows a sudden shift to a design of o-midare (大乱).  The o-midare (large irregular waviness) becomes less wavy about one or two inches below the yokote line, then continues into the boshi as a wavy hamon.  The design in the boshi is komaru-boshi.   See the illustration below. 

Ji-hada ———— Somewhat rough, (depending on the swordsmith).  Masame-hada (straight grain pattern) may show on shinogi-ji (between the ridgeline and back). 

Among the Yamashiro shin-to group, there was a group called the Mishina group (三品).  They were related to Mino-den (美濃).  Therefore, their boshi was often jizo-boshi (地蔵鋩子).  This is called Mishina-boshi (三品鋩子).  Jizo-boshi is an image of a man’s head.

2．Settu (摂津) Osaka (大阪)

Settsu (Osaka) produced more wakizashi than katana.  They tend to make it slightly sakizori (the top half curving outward) with a slightly stretched boshi. A Settsu sword also shows yakidashi, similar to the previous Yamashiro sword.  However, unlike Yamashiro’s sword, the transition is not abrupt but relatively smooth, where suguha changes into notare (wavy pattern).  This is called Osaka Yakidashi.

Osaka Boshi ——-Hamon continues up to the yokote line, then komaru with a turn back.   Ji-hada————-Very fine,  almost no pattern, a solid surface like, especially, shinogi-ji (between the ridgeline and the back).  This is called Osaka-tetsu (iron).

15| The Revival of Yamato Den（大和伝復活）

0-timeline - size 24 Late Kamakura

　　　　　　　　The red circle above indicates the time we discuss in this section

It is believed that sword-making first started in Yamato province (now Nara Prefecture) during the Nara period (710 to 794).  In the early days of sword-making, the forging techniques were primitive.  At that time, many swordsmiths lived in Yamato, but over time, sword-making in this region declined.

At the end of the Kamakura period, several powerful Buddhist temples emerged in the Yamato area, leading to conflicts among them.  Temples held significant political and military power to control large territories called shoen (荘園) through their large numbers of warrior monks, known as sohei (僧兵).  The most dominant group was Nanto Sohei (南都僧兵)*.  These groups of sohei demanded more swords to arm themselves, which revitalized the Yamato-den (school) and increased the number of swordsmiths in the Yamato area.   As a result, the Yamato-den group became active again.  The Yamato-den style is somewhat similar to the Yamashiro-den.    

*Nanto Sohei (南都僧兵)—————-Since around the 11th century, Buddhist temples grew powerful under the protection of the Joko (retired emperors).  These temples had many sohei (low-level monks who also served as soldiers). When power struggles arose among the temples, sohei fought as their soldiers on the battlefields.  Nanto Sohei were such soldiers at Kofuku-Ji Temple (興福寺).  Several large temples, such as Todai-ji (東大寺) Temple, controlled the Yamato area.

Sugata (姿: Shape) —————- Not much difference in style during the early part of Yamato–den and Yamashiro-den.  Shinogi is high.  Mune is thin.   Some Yamato-den have a shallow sori (curvature).

16 Yamato sword cross section

Hamon (刃文：Tempered line) ——————Narrow tempered line.  Mainly nie (沸).  Chu-suguha-hotsure (中直刃ほつれ: a medium straight line with a frayed pattern), ko-choji-midare (小丁子: a mixture of small clove-like patterns and irregular wavy lines), ko-midare (小乱: small irregular wavy lines), ko-gunome-komidare (小五の目小乱: small continuous half-circles mixed with wavy lines). 

The main features of the Yamato–den style sword are masame (straight grain).  Its tempered line often shows nijyu-ha (double straight lines), hakikake (brush mark trace), uchinoke (a crescent-shaped line), or a combination of these.   See the illustration below.

 

Boshi (鋩子: Tempered line at Kissaki area) ———- In the boshi area, a straight grain hamon pattern appears.  Yakizume or kaen. (Refer to Chapter 12, Middle Kamakura period: Tanto).  O-maru, ko-maru, nie-kuzure.  (Refer to Chapter 14, Late Kamakura Period Sword.  See the illustration below.)

                                      The circle indicates the time we discuss in this section

The Heian period is when the sword shape changed to the current curved form.  Before that, swords were straight.  It is widely accepted that the study of Japanese swords begins in the Heian period.   Swords made before the Heian period are considered archaeological artifacts.  The main reason is that sword-making techniques improved significantly after the start of the Heian period.

The elegant and graceful lifestyle of Heian culture is reflected in the style of swords.  A group of swordsmiths in the Kyoto region developed a specific sword style called Yamashiro-den (Yamashiro School).  The shape of their swords exhibits a graceful line.  The most famous sword of this period is Sanjo-Munechika (三条宗近 page 20), a national treasure today.  The Yamashiro-den represents the swords of the Heian period.

General Heian period sword style

The shape —————The length of a sword is about 30 inches ± a few inches.  It has an elegant, graceful shape, with a narrow blade and a small kissaki (小切先).  The curvature is deep.  This style is called Kyo-zori (京反り) or Torii-zori (鳥居ぞり).  In the Kyo-zori style, the deepest part of the curvature is near the middle of the blade.  The lower part of the sword flares out, creating an A-line shape similar to the lower part of the Eiffel Tower.  This flared shape is called funbari （踏ん張り).                                                                      

6b A line bottom

Hamon(刃文)———- Hamon is the line formed during the process of tempering.  The hamon on Heian period swords is narrow and usually suguha (直刃).  Suguha means a straight line.  The hamon is also Nie-based.  Nie(沸) are tiny particles in the hamon.   As shown below, if you look closely, you can see fine sand-like particles within the hamon line.

6 Straigh tempered line(Suguha)

10 Nie & Nioi

Ji-hada (地肌) ——–Fine wood-grained pattern.  The location of ji-hada (or ji-tetsu) is between the hamon and shinogi (see Chapter 3 |Names of Parts).

Nakago (中心)——– The nakago is the hilt area.  Sword makers inscribed their names there. During the Heian period, the nakago was often shaped like a kijimomo (雉腿), meaning a pheasant’s thigh.

6 Kijimomo-nakago

Hi and engrave ———- Hi (樋) means an engraved straight line.  Hi and other engraved designs were rare during the Heian period.  These became more common later on.

Kissaki (切先) ———– The shape of kissaki on a Heian sword is ko-gissaki, meaning small kissaki. The hamon line at the kissaki is called boshi.  During this period, the type of boshi design is called komaru, meaning small, round, and wrapping around the tip.
