        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 Yamatoden and Yamashiro-den.  Shinogi is high.  Mune is thin.   Some Yamato-den have a shallow sori (curvature).

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 Yamatoden 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 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).

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.

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.

4 | Heian Period History (平安時代歴史) 794 – 1192

The Heian Period (平安時代) began when Emperor Kanmu (桓武天皇) moved the capital to Heian-Kyo (平安京) in 794, which is now known as Kyoto (京都).

During the Heian period, emperors ruled Japan.  However, early in this era, the Fujiwara family, a wealthy aristocratic family, held actual political power. The Fujiwara family managed to marry their daughters to emperors, thereby gaining power through these marriages. The family was called “Sekkan-ke” (摂関家), meaning the guardian’s family or the emperor’s representative.

In those days, aristocrats led an elegant, refined lifestyle while cultivating a graceful culture.  Many essays and novels were written by female authors during that period.  The most famous one is “Tales of Genji (源氏物語)” written by Murasaki Shikibu (紫式部).    The Imperial Court often held ceremonies followed by elaborate, lavish banquets.  This imperial social life played an important role in advancing aristocrats’ political careers.  Women also actively participated in these ceremonies.   Many high-ranking officials owned several large estates.  Sometimes, their daughters inherited these properties and lived there.

Courtship methods were quite different back then.  To start a romantic relationship, a man would write a poem called “waka” for the lady he was interested in and have his servant deliver it to her, hoping she would write him back with a similar poem.  Once she accepted him, he was allowed to visit her for short periods from a distance.  As their relationship grew deeper, he would visit her more frequently and stay longer.  After they married, and if she was his first legal wife, she would live with him in his house.  If she were not his first legal wife, she would remain in her own home, and he would visit her for a few days or longer.  The wife’s family raised their children.  In those days, and until the next Kamakura period, a woman’s lineage was considered important.  By the middle of the Heian period, emperors regained political power because their mothers were not from the Fujiwara family.

Origin of Samurai

Although the Heian Imperial court and aristocrats lived with grace and elegance, they lacked the political power to govern the country.  There were numerous thieves, frequent fires, and constant fights everywhere.  Consequently, the Imperial court, aristocrats, and temples began hiring armed guards or security forces to protect themselves and maintain public order.  These hired guards were the origins of bushi (武士) or samurai (侍).  Samurai extended their influence and gained more power by forming groups and suppressing uprisings.  Eventually, two powerful samurai clans emerged: one was the Heishi (平氏), often called the Heike (平家), and the other was the Genji (源氏).  Gradually, they gained power in the Imperial court.   After many power struggles among them, the Heishi started to control the Imperial court by marrying their daughters to the emperors.  In the later Heian period, political power shifted to the Heishi.  They became tyrannical and arrogant.  This behavior created many enemies.  The Genji clan and the Fujiwara family started a war against the Heishi.  The Genji pushed the Heishi to the final battlefield known as Dan-no-ura (壇ノ浦) in 1185 and defeated them.  This battle was the famous Genpei-Gassen (源平合戦).  The fall of the Heishi marked the end of the Heian period.

During the Heian period, curved swords appeared for the first time.  Before that, swords had straight blades.  Historical studies of Japanese swords start from this point.  The elegant, refined lifestyle and culture created by the influential Fujiwara family were reflected in the swords’ style.  A group of swordsmiths in the Kyoto area created a distinctive sword style known as Yamashiro-den (den = school).  The shape of their blades exhibits a graceful line.  The most famous sword in the Yamashiro-den is the Mikazuki Munechika, by Sanjo Munechika (三条宗近) below, which is a national treasure today.  The Yamashiro-den style represents the swords of the Heian period.
