52|Part 2 of —–17|Late Kamakura Period Tanto (Early Soshu-Den)

Chapter 52 is the continued part of Chapter 17 Late Kamakura Period Tanto (Early Soshu-Den).  Please read Chapter 17 before reading this section.

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

In  Chapter 17 Late Kamakura Period Tanto (Early Soshu-Den), a general common characteristic of the late Kamakura period Tanto style (that is early Soshu-Den) was described.  The next two photos fit in with the common characteristic of early Soshu-Den Tanto.

Masamune Photo below

Goro Nyudo Masamune (五郎入道正宗) was born in Kamakura as a son of Tosaburo Yukimitu (藤三郎行光).  Masamune is a very well-known swordsmith even among those who are not interested in swords.  His father Tosaburo Yukimitsu is also a top swordsmith among the Early Soshu Den.  Masamune’s tombstone is in Honkaku-JI (本覚寺) temple near Kamakura train station, approximately 6 minutes’ walk from the station.

Masamune photo—– Hira-zukuri (flat)Very slightly sakizori (tip portion curves slightly outward).  Bo-hi and Tsure-hi (parallel thin groove).  Ko-maru Boshi.   Hamon is Notare (wavy).  From the illustration above, Sunagashi, Nijyuu-ba can be seen.  This type of Nakago is called Tanago-bara.   Masamune Tanto is often Mu- Mei (no signature). This particular tanto is called Komatsu Masamune (小松政宗). It is rare for Masamuneto to have wide mihaba with sori, and hamon is a little different for Masamune. Sano Museum catalog described that by judging from the clear nie, chikei, Kinsuji, this sword should be judged as Masamune.

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.

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.

20 Tokko, tume Ken

Hamon (Tempered line) —– Narrow tempered area at the lower part, gradually grows wider as it goes up toward the top then similar look wide Hamon goes into the Boshi area.  Hamon in Kissaki area is Kaeri Fukashi (turn back deep) as the illustration below.  Coarse Nie. O-Midare (large irregular pattern).

Jihada —– Loose wood grain pattern called Itame.  Yubashiri (discussed in  17 Yubashiri, Chikei.jpg), Tobiyaki (Irregular patches of tempered metal) appears.  Crowded Tobiyaki is called Hitatsura (illustration above).

During the Nanboku-Cho period, Samurais demanded large, elaborate, and impressive, yet practical sword.  The Soshu-Den style sword in Nanbochi-Cho time was just that.  This is the most popular style then.  The Nanboku-Cho period was the height of the Soshu Den.  Many swordsmiths moved from other provinces to Kamakura area and forged the Soshu-Den style swords.   Other schools and provinces outside Kamakura area also made the SoshuDen style swords in their own places.

19 Nanboku-cho Sword style

Sugata ( 姿: Shape)———-The original length of a swords was 3, 4, or 5, feet long, but shortened to approximately two and a half feet long at a later time.  A greatly shortened sword is called O-Suriage.

The Nanboku-Cho style sword has a shallow Kyo-zori (also called Torii-zori).  Refer Chapter 6 Heian period.  The highest curvature comes around the middle of the body.  A wide body, high Shinogi, narrow Shinogi-Ji.  Refer Chapter 4 Names of parts.  The thin body called Kasane is a distinctive feature for the Nanboku-cho style.  High Gyo-no-mune or Shin-no-mune, sometimes Maru-Mune (round back).
