At the end of the Kamakura period, in the Yamato area, powerful temples expanded their territories.  See the map below for the location of the Yamato area.  Several big temples, especially those with large territories, had political and military power to control the area at the end of the Kamakura period.  Those big territories were called Shoen (荘園).  They employed a large number of monk soldiers called So-hei.  The demand for swords was increased by the increased number of Sohei (僧兵).  The increased demand revived the Yamato Den.  

Some of the prominent temples had their own swordsmiths within their territory. Todaiji Temple (東大寺) backed Tegai (手掻) sword group.  The Senjuin (千手院 ) sword group lived near Senju-do (千手堂) where Senju Kannon (千手観音) was enshrined.  The name of the sword group, Taima came from the Taima-ji Temple (当麻寺).  Shikkake group (尻懸) and Hosho group (保昌) were also Yamato Den sword groups.  Those five groups are called Yamato Goha (Yamato five groups).

General Characteristic of Yamato Den

Yamato Den (大和伝) sword always shows Masame (柾目: straight grain-like pattern) somewhere on Ji-hada, Jigane, or Hamon.   Refer to 15| The Revival of Yamato Den(大和伝復活) for the general characteristic.  Masame is sometimes mixed with Mokume (burl like pattern) or Itame (wood-grain like).  Either way, Yamato Den shows Masame somewhere.  Some swords show Masame on the entire body, and some show less.  Because of Masame, the Hamon tends to show Sunagashi (brush stroke-like pattern) or a double line called Niju-ha.

                   The circle above indicates the time we discuss in this section

In 12| The Middle Kamakura Period: Tanto  described that the shape of Tanto called Takenoko-zori had appeared during the middle Kamakura period.  This style of Tanto curves inward a little at the tip.  The drawing below may be a bit exaggerated to show the curve.  The real Takenoko-zori curvature is not so apparent.  Maybe a few millimeters inward. 

Usually, the length of the Tanto is approximately 12 inches.  Tantos are described as follows; a Tanto of approx. ten inches is called Josun Tanto (定寸短刀), longer than ten inches is called Sun-nobi Tanto (寸延び短刀), and less than ten inches is called Sun-zumari Tanto (寸詰短刀).

The style above is called Kanmuri-otoshi (冠落し); the Mune side (opposite side of cutting edge) is shaved off.  The length is approximately 10 inches.  Woodgrain pattern surface, Nie on Ji (refer to 3 |Names of Parts).   Very finely forged.  Hamon is medium Suguha (straight).  Boshi is Ko-maru (small round).  Because of the Kanmuri-otoshi style, it may not be easy to see the Takenoko-zori; the Mune side bends inward very slightly.  Among the Tanto producers, Shintogo Kunimitsu is considered as the top Tanto maker.

15| The Revival of Yamato Den(大和伝復活)

0-timeline - size 24 Late Kamakura

 

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

It is said that the first sword-making started from Yamato province (present Nara prefecture) during the Nara period (710 to 794).  In the early sword-making days, their forging techniques were primitive.  At that time, a large number of swordsmiths lived in Yamato, yet as time passed, the sword making declined in this area.

At the end of the Kamakura period, several powerful Buddhist temples in the Yamato area had power struggles against each other.  Temples had a strong political and military power to control a large territory called Shoen (荘園) with their large number of warrior monks called Sohei (僧兵).  The most powerful group was called Nanto Sohei (南都僧兵)*.  The groups of Sohei demanded more swords to arm themselves.  The high demand for swords from Sohei revitalized the Yamato Den (school) and increased the number of swordsmiths in the Yamato area.   As a result, Yamato Den became active again.  The Yamato Den style is somewhat similar to that of Yamashiro Den.    

*Nanto Sohei (南都僧兵)———Since around the 11th century, Buddhist temples had become powerful under the protection from the Jokos (retired emperors).  Those temples had a large number of Sohei (low-level monks who also acted as soldiers). When power struggles started between the temples, Sohei fought as their soldiers on the battlefields. Nanto Sohei were such soldiers at Kofuku-Ji Temple (興福寺).  Several large temples such as Todai-Ji (東大寺) Temple controlled the Yamato area.

Sugata (姿: Shape) —————-  Not much difference in style at the early part of Yamato Den and Yamashiro Den.   Shinogi is high.  Mune is thin.   Some types of Yamato Den have shallow sori (curvature).

16 Yamato sword cross section

Hamon (刃文Tempered line) ——————–Narrow tempered line.  Mainly Nie (沸).  Chu-suguha-hotsure (中直刃ほつれ: a medium straight line with a frayed pattern), Ko-choji-midare (小丁子: a mixture of small clove-like pattern and irregular wavy lines), Ko-midare (小乱: fine irregular wavy lines), Ko-gunome-komidare (小五の目小乱: small continuous half-circles mixed with wavy lines). 

The main characteristic of the Yamato Den style sword is Masame (straight grain).   Their tempered line often shows Nijyu-ha (double straight lines), Hakikake (tracing of a broom mark), Uchinoke (a crescent-shape line), or combinations of them.   See the illustration below.16 Hamon Yamato

Boshi (鋩子: Tempered line at Kissaki area)———-On the Boshi area, a straight grain Hamon pattern appears.  Yakizume or Kaen. (Refer Chapter 12 Middle Kamakura period: Tanto).  O-maru, Ko-maru, Nie-kuzure.  (Refer 14| Late Kamakura Period: Sword (鎌倉末太刀).  See the illustration below.

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

The beginning of the Soshu style

A new sword style called Soshu Den emerged after the Mongolian invasion in the latter part of the Kamakura period.  Kamakura region became prosperous under the rule of the Hojo family (北条).  Many swordsmiths moved to Kamakura.  Those people were Kunituna (国綱) group from Yamashiro area and Fukuoka Ichimonji Sukezane (福岡一文字助真) and Kunimune (国宗) from Bizen area.  They are the origin of Soshu Den (相州伝).  A star swordsmith, Goro-Nyudo-Masamune (五郎入道正宗), appeared during this time.

15 Soshu sword with explanation

Shape (Sugata 姿) ——- Okissaki (large-kissak: 大切先) and Chu-kissaki (medium kissaki: 中切先).   The tip of Hi ends lower (see below illustration).  Hamaguriha was no longer in style.  The body became thinner.  The original length was approximately 3 feet or longer, but the majority of them were shortened to 2 feet and 3 or 4 inches at a later time.  The shortened sword is called O-suriage (大磨上).15 Kissak shape of 4

14 Hi end lower

Hamon——————–Narrow Hamon and wide Hamon.     

Narrow Hamon ——- A mix of Suguha (straight) and Ko-choji (small clove-like pattern), and Ko-gumome (small half-circle like pattern).  Small Nie base. (shown below)

10 Nie & Nioi

Wide Hamon———– Notare-midare (wavy), O-gunomeNie base.  Ashi-iri (short line toward the blade, the right drawing below).  Inazuma (lightning-like line) or Kinsuji (bright, radiant line) may appear on a tempered line.  However, Inazuma and Kinsuji require trained eyes to be detected.  It is hard for beginners to notice the Inazuma or Kinsuji.

15 Late Kamakura Soshu Hamon

Boshi————- The main body and Boshi has the same type of Hamon.  At the tip of the Kissaki, turn back a little or Yakizume.  You may also see O-maru (large round), Ko-maru (small round), Kaen (flame like), or Nie-kuzure.  See “Chapter 12 Middle Kamakura period: Tanto” for Yakizume and Kaen.

Jihada or Jitetsu (between Shinogi and Tempered line)—– Strong Ji-nie (地沸) that is the sand-like small dots appears on Ji (between tempered line and Mune).  Yubashiri (a cluster of Ji-nie), Kinsuji (bright, radiant line formed by Nie ), Inazuma (a lightning-like irregular line), or Chikei (similar to Kinsuji) appears on Ji-hada.
