58|Part 2 of —–22| Muromachi Period Sword (室町時代) 1393 —- 1467

Chapter 58 is the detailed part of chapter 22|Muromachi Period Sword.  Please read Chapter 22 before start reading this chapter.

As described in Chapter 22, the big change in the Muromachi Period was from Tachi  (太刀 ) to Katana (刀 ).  Refer to 22|Muromachi Period Sword.   By the end of the Nanboku-Cho period, the length of the sword became shorter.  In the Muromachi time, the length of the sword became shorter to approximately 2 feet and 3 or 4 inches in length, no more long swords.  This is because,  Nanboku-Cho period,  the fighting was done mostly riding horses but after Muromachi time, changed to infantry fighting.

Oei Bizen (応永備前 )

Oei is pronounced “O as Oh”, “ei as A of ABC”.  The Muromachi period was the declining time in sword making.  The early part of the Muromachi period is called Oei Bizen time.  Osafune Morimitsu (長船盛光 ), Osafune Yasumitsu (長船康光 ), Osafune Moromitsu (長船師光) are the main Oei Bizen swordsmiths.  Soshu Hiromasa (相州広正 )、Yamashiro Nobukuni (山城信國)  were also similar to Oei Bizen stylePlease refer to 22 Muromachi Period Sword for style, Hamon, Boshi, Ji-hada.

Above sword is 2 feet & 5 inches long, medium Kissaki, Hamon has a small wave-like pattern with continuous Gunome (half circle).   Boshi shows irregular waviness, pointed at the tip a little.  It shows Bo Utsuri (faint shadow shaped like a strip of wood).  Bo Utsuri is a well-known characteristic among all of the Oei Bisen. 

In the Bizen area until this time, there were many groups within Bizen, but in Muromachi time, only Osafune (長船) was the active swordsmith group.  Osafune (長船) is the name of the place,  but in Muromachi time, it started to become the last name.  Two other well-known swordsmiths among Oei Bizen are Morimitsu (盛光 ) and Yasumitsu (康光).  The Hamon by Morimitsu and Yasumitsu shows more works in it than the photo above.  That is described in 22 Muromachi Period Sword under the usual characteristic of Muromachi sword.

22|Muromachi Period Sword

21 Muromachi period Timeline

The circle indicate the time we are discussing in this section

The Muromachi period was a rather peaceful and prosperous time until a little before “Onin-no Ran”, which was the later part of the Muromachi Period, (Refer Chapter 21 Muromachi Period History).  Nanboku-Cho style long sword became useless, as a result, they were shortened.  The shortened sword is called Suriage.  In general, the Muromachi period was a declining time for sword making.

Tachi and Katana

Until the end of the Nanboku-Cho period or beginning of the Muromachi period, the sword was suspended from one’s waist, the blade side down.  When a sword was worn this way, swordsmith’s inscription faces outsite.  That means when you see the inscription, the cutting side comes right.  This is called Tachi.  Yet, around

the Muromachi period, swords were worn between one’s belt, the blade up.   The inscription of the swordsmiths faces outside when it is worn.  That means when you see the inscription, the cutting edge comes your left.  This is called the Katana.  Around the beginning of the Muromachi period samurai started to wear one pair of swords together called Dai-Sho(大小), which means large and small.  A longer one is called Katana and the shorter one is called Wakizashi.  In general, Tachi is longer and Katana is shorter, Wakizashi is even shorter but longer than Tanto.  Here is the order of the length.

                                            TachiKatana  >  Wakizashi  >  Tanto        

The difference between Tachi and Katana comes from the way it was worn, not the length

22 tachi & Katana

 

O-Suriage ( shortened a large length, 大磨上げ)

How long a sword should be shortened is depends on the original length of the sword and how long an owner want it shortened.  O-suriage is when a sword is shortened a great length.  Once a sword is shortened, the inscription is cut off.  When a suriage sword was appraised by the Hon’ami family (本阿弥家:Connoisseur family continued since mid Edo period till almost recent day), if he  appraised it as a valuable one,  he writes the make of the sword and sword smith’s name on the front side of the hilt and writes the connoisseur’s name and his Kaou (similar to signature) on the back of the hilt.  There are several ranks.  Which rank it should be done is depending on the quality of the sword and how an owner wants it.  Below are the ranks (lower to highest).

Shu-Mei (朱明 )———————————————————–name written in Vermilion  Kinpun-Mei (金粉名 )———————————————-name lacquered in gold powder  Gin-Zougan (銀象嵌 )————————————————————-name inlaid in silver  Kin-Zougan (金象嵌 )—————————————————————name inlaid in gold

Sugata (姿 shape)———Usually approximately 2 feet and 3, 4 inches (71cm) long. The shape of the Muromachi period Katana is somewhat like the 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 the sword are 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, 2 inches long.  No curvature.  Hirazukuri-Wakizashi appeared During Muromachi time.

18 Nanbokucho time line

The circle indicates the time we are discussing in this section

 

During the Nanboku-Cho Period, the type of Tanto called Hirazukuri-Kowakizashi-Sunnobi-Tanto was made.  Hirazukuri means a flat sword without the Yokote line and without Shinogi.  Ko-Wakizashi means a shorter sword.  Sun-Nobi Tanto means longer than standardThis is also called Enbun Jyoji Kowakizashi Tanto.  It is called this way because the majority of this type Tanto was forged around Enbun, Jyoji Imperial era.  In Japan, each time the Emperor changed, we changed the names of the era.  Enbun was from 1356 to 1361, Jyoji was from 1362 to 1368

 

20 Enbun Jyoji Kowakizashi Tanto

Shape (Sugata 姿) ——-It is common idea that the length of Tanto should be 1 shaku or less.  Shaku is an old Japanese measurement unit, which is very close to 1 foot.  8.5 sun (old Japanese measurement unit) is approximately 10 inches. This is the standard length Tanto called Jo-Sun Tanto.  Anything longer than Jo-Sun Tanto is called Sun-Nobi Tanto.  Anything shorter than Jo-Sun is called Sun-Zumari Tanto.  Most of the Nanboku-Cho Tanto is approximately 1 foot 2 inches long, therefore they are called Hirazukuri-Kowakizashi-Sun-Nobi Tanto Sakizori (curved outward at the top.  See the illustration above).  Wide width and thin body.  Fukura Kareru (No Fukura). Shin-no-Mune.  See the illustration below.
