14 Ikubi kissaki Damadge

In Chapter 14| Late Kamakura Period: Sword (鎌倉末太刀), the Ikubi-kissakui sword was explained.  The above illustration shows a flaw that was caused when the damaged area was repaired.  To compensate for this flaw, swordsmiths started a new sword style in the late Kamakura period.  They forged swords with a longer Kissaki and stopped the tip of Hi at a lower point than the Yokote line.   This way, if the Yokote line was lowered when it was repaired, the tip of Hi would stay lower than the Yokote-line.

The above photo is a sword by Goro Nyudo Masamune (五郎入道正宗 ).  Please look at the size and shape of the Kissaki.  This is different from previous Ikubi-kissaki, or Ko-gissaki.  This is a typical late Kamakura period Kissaki style.  This is O-suriage (largely shortened). 

Under Kamakura Bakufu, many swordsmiths moved to KamakuraThey were Toroku Sakon Kunituna (藤六左近国綱) of Yamashiro Awataguchi group (山城粟田口),  Fukuoka Ichimonji Sukezane (福岡一文字助真), and Kunimune (国宗) from the Bizen area.  They were the origin of Soshu Den (相州伝)Eventually, Tosaburo Yukimitsu (藤三郎行光) and his famous son,  Masamune (正宗), appearedIn the drawing above, Kinsuji and Inazuma are shown inside the Hamon.  The shinning lines inside the Hamon are Inazuma and Kinsuji.  Inazuma and Kinsuji are a collection of Nie.  Masamune is famous for Inazuma and Kinsuji.  Masamune lived in Kamakura; his Hamon looks like ocean waves when it is viewed sideways.

The above picture is a sword by a swordsmith of Yoshioka Ichimonji group (吉岡一文字).  The Kissaki is also like the one of Masamune’s.  It is longer than the previous Ikubi-kissaki or Ko-gissaki.  This is Chu-gissaki.  The Kissaki like this is one of the crucial points to determine what period the sword was made.  The Hamon has Choji, Gunome, Togariba (pointed-tip), and very tight Nie.

The above photo is a sword by Ukai Unsho (鵜飼雲生) of Bizen Den.  This sword is also from the late Kamakura period.  But it has Ko-gissaki.  This sword does not have the late Kamakura period Chu-gissaki style.  Narrow Hoso-suguha is somewhat like an earlier time than the late Kamakura period.  This sword indicates that the sword does not always have the style of that period.  To Kantei*, first, look at the style and shape then give yourself some idea of the period of the time it was made.  But in this case, Kissaki does not indicate the late Kamakura periodThe next thing is to look at the different characteristics of the sword one by one like Hamon, Nie or Nioi, Jihada, etc.,  and determine what period, which Den, which province and then come up with the name. This process is called Kantei.

*Kantei —  to determine the swordsmith’s name by analyzing the  sword characteristic without seeing the Mei (inscribed swordsmith name). Mei may be gone if it was shortened.

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

The Kamakura period was the golden age of sword making.  Approximately half of the well-known swords at present were made during the Kamakura period.  It is probably because the war between the Genji and the Heishi demanded many swords, and the swordsmiths improved their swords through the war experience.  Also, Emperor Gotoba (後鳥羽) invited many skilled swordsmiths to his palace and treated them highly, and encouraged them to create excellent swords by giving them high ranks.  During the Kamakura period, the techniques of sword making improved significantly.

Middle Kamakura Period —- Yamashiro Den (山城伝)

The Middle Kamakura period was the height of the Yamashiro Den.  Among Yamashiro Den, there were three major groups (or families).  They are Ayanokoji group (綾小路), Awataguchi group (粟田口), and Rai group (来).

Among the Awataguchi group, six swordsmiths received the honor as the “Goban-kaji ” from the Emperor Gotoba (後鳥羽上皇).  Awataguchi is the name of an area in Kyoto. 

Ayanokoji ( 綾小路 ) group lived in the Ayanokoji area in KyotoMy sword textbook had a note that I saw Ayanokoji Sadatoshi (綾小路定利 ) on March 22nd, 1972.  The note was not much but it said O-suriage, Funbari, narrowbody, and Ji-nie.

Rai group started from Rai Kuniyuki (来国行 ).  Rai Kuniyuki and Ayanokoji Sadatoshi are said to have had a close friendship.  Rai Kuniyuki created many well-known swords.  His famous Fudo Kuniyuki (不動国行) was owned by Shogun Ashikaga Yoshiteru (足利義輝 ), then changed hand to Matsunaga Danjo (松永弾正), then to Oda Nobunaga ( 織田信長 ) to Akechi Mitsuhide (明智光秀 ), then to Toyotomi Hideyoshi (豊臣秀吉).  They were all historically famous powerful Daimyo.  It is said that Toyotomi Hideyoshi held this sword for the memorial service of Oda Nobunaga.  Rai Kuniyuki’s son was Niji Kunitoshi.  He also created well-known swords.

Middle Kamakura Period —– Bizen Den (備前伝)

The Bizen Den during the Heian period was called Ko-bizen.  They are similar to the one in the Yamashiro Den style.  The true height of the Bizen Den was in the Middle Kamakura period.  The Bizen area (today’s Okayama prefecture) had many ideal aspects for sword making: the good climate, the good production of iron, the abundant wood for fuel, and the convenient location. Naturally, many swordsmiths moved there, and it became a major place to produce swords.

The Bizen region produced many swords whose quality level was higher than other sword groups and more famous swordsmiths.  Fukuoka Ichimonji Norimune (則宗) and his son Sukemune (助宗 ) received the honor of the Goban-kaji from the Emperor Gotoba.

 Among the Osafune group (長船), famous Mitsutada (光忠) and Nagamitsu (長光) appeared.  My father owned four Mitsutada.  Three Tachis and one Tanto.  He was so proud of owning four Mitsutada that he asked his tailor to monogram Mitsutada on the pocket inside of his suit jacket.

From Hatakeda group (畠田), Hatakeda Moriie (畠田守家), and from Ugai (鵜飼) group, Unsho (雲生 ) and Unji (雲次) appeared.  The famous Kunimune (国宗) also appeared around this time.   Because there were many swordsmiths in the Bizen Den, a large number of Bizen swords exist today.  Each swordsmith showed his own characteristics on their swords.  Therefore, kantei on Bizen  swords can be complex.  This is the time Ikubi Kissaki appeared.

Below are my father’s four Bizen Osafune Mitsutada.  He took those pictures many years ago at home.  You can see he was not much of a photographer.  He wrote the name of the swordsmith, the period the sword was made, the name(s) of Daimyo who owned it in the past, and the classification on a rectangular white paper.

Late Kamakura Period —– Soshu Den (相州伝 )

Yamashiro Den started to decline in the latter part of the Kamakura Period.  At this time, many swordsmiths moved to the Kamakura area under the new power of Kamakura Bakufu (鎌倉幕府) by the Hojo clan.  The new group, Soshu Den (相州伝 ), started to emerge.  Fukuoka Ichimonji Sukezane (福岡一文字助真) and Kunimune (国宗) from Bizen moved to KamakuraToroku Sakon Kunitsuna (藤六左近国綱) from Awataguchi group of Yamashiro Den moved to KamakuraThose three are the ones who originated the Soshu Den in Kamakura. Kunitsunas son is Tosaburo Yukimitsu, and then his son is the famous Masamune (正宗)Outside of Kamakura area, Yamashiro Rai Kunitsugu (来国次), Go-no-Yoshihiro (郷義弘) from Ettshu (越中) province, Samoji  (左文字) from Chikuzen province (筑前) were the active swordsmiths.

17| Nanboku-cho Period History 1333-1392(南北朝歴史)

0-timeline - size 24 Nanboku-cho

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

After Jokyu-no-Ran (Chapter 10 Jokyu-no-Ran), the power of the Imperial Court declined significantly.  The successor, the Hojo clan with a dominant power during the Kamakura period, also began to have financial difficulty and started to lose control over the regional lords.  One of the reasons was the cost incurred by the Mongol invasion.  The Kamakura Bakufu (government) could not reward well to the Samurai who worked hard during the war.  As a result, they were very dissatisfied with the Bakufu.  Seeing this as a chance, Emperor Go-Daigo attempted to attack the Kamakura Bakufu two times but failed both times.  He was exiled to Oki island.  Meantime, Ashikaga Takauji (足利尊氏) and several groups of anti-Kamakura Samurai gathered arm forces and succeeded in destroying the Kamakura Bakufu (1333).  This war ended the Kamakura period.

Emperor Go-daigo, who had been exiled to Oki island, returned to Kyoto and attempted political reforms.  This reform was called Kenmu-no-Chuko (or Kenmu-no-Shinsei, 建武の中興).  His reform, however, failed to satisfy most of the ruling class.  Taking advantage of this situation, Ashikaga Takauji attacked the Imperial Court in Kyoto, deposed Emperor Go-daigo, and placed a member from the other branch of the Imperial family on the throne. 

Emperor Go-daigo, however, insisted upon his legitimacy, moved to Yoshino in the South of Kyoto, and established another Imperial court.  Thus began the Northern and the Southern Dynasties.  With much strife between these rival courts and their problems within each court,  more Samurai groups began moving to the Northern Dynasty.  About 60 years later, the Southern Dynasty was compelled to accept the Northern Dynasty’s proposal.  Consequently, the Northern Dynasty became the legitimate imperial court.  These 60 years are called Nanboku-cho or Yoshino-cho period. 

During the Nanboku-cho period, Samurai demanded larger and showy yet practical swords.  Soshu Den was the height of its prominence.  However, the Soshu group was not the only group that made the Soshu Den style swords.  Other schools and provinces of the different areas also made Soshu Den style swords.

13| Late Kamakura Period: Genko (鎌倉末元寇)

0-timeline - size 24 Late Kamakura

                       The circle represents the time we discuss in this section

GENKO 元寇  (1274 and 1281)

The grandson of Genghis Kahn, Kublai Kahn, attempted to invade Japan twice in 1274 and 1281.  Both times, a strong typhoon hit Japan.  Mongols sent a large number of soldiers with all kinds of supplies on a huge number of ships to Japan.  Those ships had to stay side by side and front and back very close to each other in the limited area of Kyushu‘s shore.   When the strong wind came, ships were swayed, hit each other, and capsized.  Many people fell into the ocean, drowned, and lost supplies in the water. Even though Mongol soldiers landed and fought with the Japanese army, they did not have much choice but to leave Japan because of the typhoon and ships wrecking.   As a result of this strong wind, Japan was saved and looked as if Japan won. 

This is the time the famous Japanese word, “Kamikaze” (divine wind) was created. Actually, Mongols had many  superior weapons than the Japanese.  They had guns, while the Japanese did not.  Their group fighting method was much more superior and effective than the Japanese one-to-one fighting method. 

After the Mongolian invasion, the need for changing the style of the Ikubi Kissaki sword became obvious.  When swords were used in a war, the area most frequently damaged was the Kissaki area.  Japanese soldiers used mostly Ikubi-kissaki swords in this war.  An  Ikubi-kissaki Tachi has a short Kissaki.  When a damaged area of the Kissaki was whetted out, the top part of the Yakiba (tempered area) disappears, and the Hi (a groove) goes up too high into the Boshi area (top triangle-like area).  Short Ikubi-kissaki becomes even shorter, and the Hi goes up too high into the Boshi area.  Aesthetically, it is not appealing.  Functionally, it does not work well.  To compensate for the flaw, a new style began to appear in the latter part of the Kamakura period.

14 Ikubi kissaki Damadge

During the latter part of the Kamakura period, the swordsmiths began to create a new swords style to compensate for this fault.  Also, the pride and confidence had grown among people after driving the Mongols away, which reflected on the swords’ appearance. Generally speaking, the Hamon and the shape of the body became stronger and showier.

Kamakura area became a very prosperous place under the power of the Hojo family.  A large number of swordsmiths moved to Kamakura from Bizen, Kyoto, and other places during this time and created a new style.  This is the beginning of the Soshu Den (Soshu is the Kanagawa area now).  Many famous top swordsmiths appeared during this time.

One of the famous swordsmiths is Goro-Nyudo Masamune (五郎入道正宗).  The Masamune’s tomb is in the Honkaku-Ji temple in Kamakura.  That is about a 5 or 6 minutes’ walk from the Kamakura train station. 

While I was attending the sword study group of Mori Sensei (teacher), one of the students I studied with was the 24th generation of the direct descendants of Masamune.  Although he does not bear the name of Masamune, he has been making wonderful swords in Kamakura.  He also makes superb kitchen knives.  The name of his shop is “Masamune Kogei (正宗工芸),and it is located a short walk from  Kamakura station.  To find his place, ask at the information center in the train station.
