Introduction Of  The Five Main Sword School (Den)

There are five major sword schools (Den): Yamashiro Den (山城), Bizen Den (備前), Soshu Den (相州), Yamato Den (大和), and Mino Den (美濃).  During the Heian period, Yamashiro Den was the main and most active school.  A school called Ko-bizen (meaning Old Bizen) during the Heian period is a part of Bizen Den.   However, we take the Ko-bizen separately since their style is slightly different from the later Bizen Den but somewhat close to the Yamashiro Den as we see it later.

During the Heian period, the swordsmiths of Yamashiro Den lived around Kyoto, the capital of Japan then.  In the early Kamakura period, Yamashiro Den maintained the similar sword style they created in the Heian period.  Bizen Den appeared in the middle Kamakura period.  Soshu Den appeared in the late Kamakura period in Kamakura area.  Mino Den appeared in the Muromachi period, which comes much later.

The Early Kamakura Period (鎌倉

We divide the Kamakura period into three stages: the early, the middle, and the late Kamakura period. The sword style in the early Kamakura period was almost the same as in the previous Heian period.  Yamashiro Den was continuously the most active school through the early Kamakura period.

The Middle Kamakura Period 

In the middle Kamakura period, we have three different styles of the sword to discuss: the Yamashiro Den style, the Bizen Den style, and the Ikubi-kissaki (猪首切先) style, which was new at that time.  We can say that among the Ikubi-kissaki swords, seldom sees the mediocre sword.

The previous section described the Kamakura Bakufu (鎌倉幕府: government) had political and military power, yet the emperor was still on the throne in Kyoto.  Emperor Gotoba raised an army and attacked the Kamakura government to regain political control.  This war (1221) is called Jyokyu-no-Ran (承久の乱).  The war changed the look of swords to a sturdier shape.  This style is what we call the Ikubi-kissaki.

The Late Kamakura Period (after the Mongolian Invasion)

During the late Kamakura Period, Soshu Den emerged in addition to Yamashiro Den and Bizen Den.  After the two Mongolian Invasions called Genko (元寇) in 1274 and 1281, longer and broader swords with longer Kissaki began to appear.  The Soshu Den swordsmiths forged this type of sword

Engravings on Sword

Engravings on a sword in the Ko-to era (Heian to Keicho era) has three purposes.  One is to reduce the weight of the sword.  Hi, Bohi, Gomabashi (wide, narrow, short, or long grooves) are examples.  The second is for religious purposes, for which swordsmiths often carved Buddhistic figures.  The third is for decoration.  In the Shin-to era (from Keicho time and after), it became mainly for decoration purposes.

The figures below are examples of the engravings.

Preface and Biography

Preface

This is a series of entry-level lectures of the Japanese sword and its history for those who are interested in studying Japanese art swords.

The Japanese sword was basically designed as a weapon, but Japanese swordsmiths imbued qualities of grace and beauty into the blades as well as functional superiority.  The intricate patterns of surface and texture formed by their highly developed forging and tempering techniques were used only in Japan.  In the past, the Japanese looked at the swords as a spiritual symbol of Samurai, temples, and shrines.  Nowadays, the Japanese regard swords as a cultural art object made of steel.

Varieties of the appearance of swords are closely related to historical events.  Textures, contours, and tempering designs are characteristics of a particular school (Den 伝) of swordsmiths.  This is a series of lectures that discuss each period’s history then talk about the swordsmiths’ schools that were active in a particular province at the time. Because of that, each section starts with the history of the time.   It is necessary to discuss the history to see the flow of the events that affected the swords’ shape and style.

Since the subject matter covers many centuries, I will concentrate more on “Ko-to” (古 刀), which appeared from the Heian period (平安時代 794 – 1185) until the end of the Sengoku period (戦国時代 16th cent).  These lectures will be discussed with my illustrations and photos of swords from my father’s collection* and the Sano Museum Catalogue**.  Also, I referenced the book, “Nihon-to no Okite to Tokucho (日本刀の掟と特徴: The Rules and Characteristics of Japanese Sword)” by Mr. Honami Koson.  This is the book my sword teacher, Mori Sensei, used as the textbook in his class.  Other referenced books are, “Token no Mikata (刀剣のみかた: The Way to Look at Swords)” by Mr. Yuichi Hiroi whom I have known since my intern days in the Japanese Sword Museum, “Nihonto Taikan (日本刀大鑑),” “Nihonto Koza (日本刀講座),” and several more.  The detailed information on those Referenced books is in the bibliography.

 Biography

I was born and raised in Minato-ku, Tokyo, Japan.  Then we moved to Kamakura in my late teens.  Currently, I live in Los Angeles.  I graduated from Meiji University and received a bachelor’s degree in literature and a curatorship license.  The required internship for the curator license was done at Nihon Bijutsu Token Hozon Kyokai (日本美術刀剣保存協会: The Japanese Sword Museum, often called NBTHK) in Tokyo.  Also, I graduated from the California State University of Northridge and received a bachelor’s degree in Economics.

My father owned a manufacturing company that dealt with metal.  As his hobby, he had collected Japanese swords and other types of Japanese art objects.  He was one of the administrators of Nihon Bijutu Token Hozon Kyokai.    He had been long deceased. 

One of my father’s friends, Mori Sensei who was also the main administrator of the organization, used to have a Japanese sword study group in his house near my house.  I joined the study group.   Mori sensei’s class was a very rare and valuable kind because he was able to bring in top-quality swords as study materials because of his position in the museum.  The kind of swords we studied with were top-quality museum swords, like Juyo Bunkazai (Important Cultural Properties), Juyo-Bijutsuhin (Important Art Object).  I don’t know how he managed to do it, but he even brought one National Treasure sword.  Keep in mind things were a little different over 50 years ago.  Those were the kind of swords people could only see through the glass display cases. 

Also, I studied the swords with my father since he kept many swords in our house.  Some photos of his swords are in pages of many chapters in this book. 

*My father took the photos of his swords; those were his swords when the photos were taken.
