21 Muromachi period Timeline

The circle indicate the time we are discussing in this section

Long strife between North and South Dynasty ended.  Even though the government was corrupted at the later part of the Muromachi Period, at least until the “Onin-no-Ran”, (refer 21 Muromachi period historyMuromachi period was a rather peaceful time.  Nanboku-Cho style longs word became useless and they were shortened.  This is called Suriage.  In general, Muromachi period was a declining time for sword making.

Tachi and Katana

Until the end of the Nanboku-Cho period, the sword was suspended from the waist, cutting side faces down.  Swordsmiths inscribed their names facing out when it was worn.  That means when you see the inscription, the cutting side comes right.  This is called Tachi.  Around Muromachi period, swords were worn inside the belt, the cutting side up, and the inscription of the name facing out when it is worn.  That means when you see the inscription, the cutting side comes left.  This is called Katana.  Samurai usually wore one pair of swords together called Dai-Sho(大小), that means large and small.  Longer one is Katana and the shorter one is Wakizashi.  In general, Tachi is longer and Katana is shorter, Wakizashi is even shorter but longer than Tanto. The difference between Tachi and Katana comes from the way it was worn, not the length.

2b Tachi & Katana difference

O-Suriage ( shortened 磨上げ)

When the shortened (suriage) sword was appraised as a valuable one, Hon’ami family (Connoisseur family generation to generation) judged the make of the sword and wrote sword smith’s name on the front side of the hilt and signed the connoisseur’s name on the back of the hilt.  When the sword was shortened a lot, it is called O-Suriage.

Shape (Sugata 姿)———Usually approximately 2 feet 3 or 4 inches (71cm) long. The shape of the Muromachi period Katana is somewhat like Heian period Tachi style.  But Muromachi Katana is not as grand, not as graceful as Heian period sword.  They are Koshizori.  Koshizori shape means the highest curvature comes lower than the center of the blade.  Suitable length and shape for wearing inside the belt. The width and the thickness of sword is well balanced with the length.  Small Kissaki.

Hirazukuri-Wakizashi———–Hirazukuri means a flat surface with no Shinogi and no Yokote line.  Usually One foot and 1 or 2inches long.  No curvature.  Hirazukuri-Wakizashi appeared During Muromashi time.

21|Muromachi Period

18 Nanbokucho time line

The circle indicate the time we are discussing in this section

Ashikaga Takauji(足利尊氏) was the one of the main people who ended Kamakura Bakufu and started Nanboku-Cho period – North and South dynasty -(refer to 18 Nanbokucho – history).  His grandson, Ashikaga Yoshimitsu (often called Shogun Yoshimitsu) built a new beautiful Palace at Muromachi (室町) in Kyoto.  This palace became the center of the government called Muromachi Bakufu (室町幕府), therefore, we call this time Muromachi period.  Ashikaga Yoshimitsu built famous “Kinkakuji Temple” (golden pavilion)*.

In Muromachi period, emperor’s power became weak, instead shogun (将軍) held all the political power. Little by little, several groups of samurai who were called Shugo Daimyou (守護大名), started to gain the political power and economic power by holding the important offices in the Muromachi Bakufu (government).  They also owned large land.  Some of the names of Shugo Daimyo were Hosokawa family, and the Yamana family.

Ashikaga family made a great effort to make the Muromachi Bakufu a sound political power through the political maneuver.  Yet by the time Ashikaga Yoshimasa (grandson of Yoshimitsu) became the Shogun, the Bakufu was corrupted very badly.  Shogun Yoshimasa did not pay attention to his job as a politician.  Instead, he was chasing women (his mother had to scold him for that), spend a huge amount of money to build a Silver Pavilion called “Ginkakuji” and retreated himself in there.  Shogun Yoshimasa did not have an heir.  Therefore his brother, Yoshimi was decided to be the next Shogun.  But later, Yoshimasa’s wife Hino Tomiko (日野富子)* had a son, Yoshihisa (義尚).  Now, brother Yoshimi (義視) allied with the Hosokawa (細川), Yoshihisa, the son allied with the Yamana (山名) and several other smaller groups of Samurai allied with either side, started a big battle.  This is called Onin -no-Ran (応仁の乱) at 1467 and spread all over and continued for 11years.

As a result of this battle, beautiful Kyoto was burnt down to ashes, the authority of Muromachi Bakufu was reduced to the only a small surrounding area.

*Kinkakuji Temple (金閣寺) Golden Pavillion—————-Ashikaga Yoshimitsu (足利義満) built Kinkakuji in 1397. Rinzai-shu (臨済宗) school Buddhistic Temple, it was originally built as his second house.  It is designated as the world heritage.  It was burnt down by the arsonist in 1950, rebuilt in 1955.  The novelist Mishima Yukio wrote the novel  “Kinkakuji” dealing with the Golden Pavillion and as an arsonist.  The famous quote, “The gold bird (Houou in Japanese, it is a Chinese phoenix) on the roof of the Kinkakuji temple is stationary but fly through the space of the time eternally”

*Hino Tomiko (日野富子)——————The wife of Shogun Yoshimasa.  She took advantage of her political privileges to raise a large amount of money, then loaned them to the high officials with high interest.  She also invested in rice commodity market to raise the price of rice and sold with a high profit.  The corruption reached to an uncontrollable level.

The type of Tanto during Nanboku-Cho Period was called  Hirazukuri-Kowakizashi-Sunnobi- Tanto.   Hirazukuri means flat sword without Yokote line and without Shinogi. Ko-Wakizashi means shorter sword. Sunnnobi Tanto means longer Tanto. This is called Enbun Jyoji Kowakizashi Tanto.  Because the majority of this type of shape was made around Enbun, Jyoji Imperial era.  Each time the Emperor changed, Japan changed the names of the era.  Enbun was from 1356 to 1361, Jyoji was from 1362 to 1368.

During Nanboku-Cho period, Samurai demanded large, elaborate and practical swords. Soshu Den style — elaborate, large, and impressive  —became the most popular style. Nanboku-Cho period was the height of the Soshu Den.  Many sword smiths moved to Kamakura and forged Soshu Den style swords.  Other schools and provinces also made Soshu Den style swords in their own places.

19 Nanboku-Cho Period Sword shape

Shape (Sugata 姿)—-Originally the length of the swords were 3, 4, 5, feet long, but shortened to approximately two and a half feet in the later time.

18|Nanboku(Yoshino) Cho Period —— North and South Dynasty (1333-1393)

 

18 Nanbokucho time line

The circle indicates the time we are discussing in this section.

After Jokyu-no-Ran (11|Jokyu-no-ran ), the power of the Imperial court declined significantly. The Hojo clan who were the main power during the Kamakura period began to have the financial difficulty and started to lose the control over the local lords. One of the reasons was that the cost incurred by the Mongolian invasion. The Kamakura Bakufu (government) could not reward the local lords who worked hard at this war. The local lords became very dissatisfied with the Kamakura Bakufu. Seeing this as a chance, the Emperor Go-Daigo twice attempted to attack Kamakura Bakufu but failed both times and he was exiled to Oki island. Meantime, Ashikaga Takauji (足利尊氏) and several other groups of Samurai who were opposing the Kamakura Bakufu, gathered their power and succeeded in destroying the Kamakura Bakufu (1333). This ends the Kamakura period. The Emperor Go-Daigo, who had been exiled to Oki island returned to Kyoto and attempted established political reforms. This is called Kenmu-no-Chuko (建武の中興).  This new policy failed to satisfy the most of the ruling class.  Taking advantage of this situation, Ashikaga Takauji attacked Imperial court in Kyoto, deposed the Emperor Go-Daigo and placed the other branch of the Royal family on the imperial throne.  But the Emperor Go-Daigo insisted upon his legitimacy, moved to Yoshino (located the South of Kyoto) and established a rival Imperial court.  Thus began the North and the South dynasty.  Much strife between the North and the South and also, both side had their own problems within themselves.  Eventually more Samurai group went under the control of North dynasty.  About 60 years later, Southern dynasty was compelled and accepted the Ashikaga clan’s proposal. Thus, established the North Dynasty as the legitimate imperial court.  This 60 years is the time called Nanboku-Cho or Yoshino-Cho period.  During Nanboku-Cho period, Samurai demanded larger and showy, and practical swords.  Soshu Den was its height of their prominence.  That does not mean only Soshu group made all the swords.  Other schools and other provinces also made Soshu Den style swords.

Early Soshu den time (that is late Kamakura period), Yukimitu (行光), Masamune (正宗) and Sadamune (貞宗) were representative swordsmiths.   Middle Soshu den time (that is North and South dynasty time), Hiromitu (広光), Akihiro (秋広) were representative swordsmiths.  Late Soshu den time (that is Muromachi period), Hiromasa (広正), Masahiro (正広) was the representative swordsmiths.

16|The Revival of Yamato School

15TimelineThe circle represents the time we are discussing in this section

Yamato province (it is Nara prefecture presently) is the area where sword making started originally.  In early days, they forged swords with their primitive skills.  A large number of swordsmiths lived in this area.  Their style is similar to that of Yamashiro school. At the end of the Kamakura period, Kamakura government started to have financial problems.  Armed monks from Kofuku-Ji temple called Nanto Sohei (Armed monks who lived south side of  Kyoto)* demanded more and more swords to arm themselves.  This demand of the swords revitalized the Yamato School that led to increasing the number of the swordsmith.   As a result, Yamato School became prosperous.

*Nanto Sohei(南都僧兵)———Around the 11th century, Buddhist temples became powerful under the protection of JoKo(former Emperor).  Those temples had a large number of Sohei  (low-level monks who also acted as soldiers) under them.  For the power struggles between the temples, Sohei went to battles fields. Nanto Sohei were monk soldiers of Kofukuji temple.  The aristocrats were afraid of the dignity of God and Buddha, and also did not have enough spirit to suppress them, they had to depend on samurai.  That gave samurai a chance to be a powerful group among the center of the ruling class.

Shape(Sugata姿) —————-1. Graceful Yamashiro style retained. 2. Shinogi is high.  3. Mune is thin.  4. Some group of Yamato school has shallow Sori (curvature).

After the Mongolian invasion, that is the later part of Kamakura period, a new style started to emerge.  Kamakura area became prosperous under the rule of Hojo(北条).  Many swords smiths moved to Kamakura. Fukuoka Ichimonji (福岡一文字)Sukezane, Kunimune group moved from Bizen. Kunituna and his group moved from Yamashiro.  They are the origin of Soshu school (相州).  A star sword smith, Goro-Nyudo-Masamune (五郎入道正宗) appeared during this time.

14 Timeline The circle represents the time we are discussing in this section

 

GENKO 元寇  (1274 and 1281)

The grandson of Genghis Kahn, Khubilai Kahn attempted to invade Japan two times in 1274 and 1281.  Both times, a strong typhoon hit Japan.  Mongol sent a large number of soldiers with all kinds of supplies on their huge numbers of ships.  Those ships had to dock side by side and front and back very closely at the limited area of shore.   When the strong wind came, ships were swayed, hit each other and capsized.  Many people were drowned and lost supplies in the water.  Even though they landed and attacked Japan, because of the typhoon and ships wrecking, they left Japan.  As a result Japan won.   Actually, Mongol had much superior weapons than Japanese.  They had guns, Japanese did not.  Their group fighting method was much more superior and effective than Japanese individual  fighting method.  This is the time the word “Kamikaze” (God wind)  was created.

After the Mongolian invasion, the need for the changing the style of the Ikubi Kissaki became obvious.  When swords were used in a war, the most frequently damaged area was a Kissaki area.  Japanese soldiers used mostly Ikubi Kissaki swords in this war.  The Ikubi Kissaki Tachi has a short Kissaki, therefore, when the damaged area of the Kissaki was polished down for repairing, the top part of the Yakiba (tempered area) disappeared and the Hi (groove) goes up too high in the Boshi area (top triangle-like area).  Functionally, short Ikubi Kissaki becomes even shorter, and Hi goes up too high into a Boshi area became a flaw.  To compensate for this flaw, a new style began to appear in later part of Kamakura period

14 Ikubi kissaki Damadge

 

During later part of Kamakura period, the swordsmiths began to create a new style of swords to compensate for this fault.  Also, people’s enthusiasm (that was raised by driving back Mongolian) reflected on the surface of swords.  Generally speaking, Hamon and a shape of the body became showy and stronger looking.

Kamakura became a very prosperous place under the power of 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 Soshu school (presently Kanagawa area).  Many famous top swordsmiths appeared during this time.  One of the famous swordsmiths is Masamune.  Masamune’s tomb is in Honkaku-Ji temple that is about 5 minutes walk from the Kamakura train station.  When I was attending the sword study group of Mori Sensei(teacher), one of the students I studied with was the 23rd generation of direct descendants of Masamune.  He still makes swords in Kamakura.  He also makes wonderful kitchen knives.

 

13|Tanto(dagger) Middle Kamakura Period

13-time-line.jpg

It is very rare to see a tanto (dagger) made during the Heian period.                            Middle Kamakura period, a large number of wonderful tanto were made.  They were called takenoko-zori shape.  Takenoko means bamboo shoot.  The back of the dagger curves inward slightly.
