At the end of the Kamakura period, powerful temples expanded their territories in the Yamato region.  Refer to the map below for the location of the Yamato region.  Several prominent temples, especially those with large territories, held political and military power to control the area at the end of the Kamakura period.  These large territories were called shoen (荘園).  They employed many monk soldiers known as so-hei.  The demand for swords increased because of the rising number of Sohei (僧兵).  This increased demand revived the Yamatoden.  

Some prominent temples had their own swordsmiths within their territories. Todaiji Temple (東大寺) supported the 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) is enshrined.  The Taima sword group originated from the Taima-ji Temple (当麻寺).  The Shikkake group (尻懸) and the Hosho group (保昌) were also part of the Yamato-den sword groups.  These five groups are known as Yamato Goha (the Yamato five groups).

General Characteristic of Yamato Den

The Yamato-den (大和伝) sword always shows masame (柾目: straight grain-like pattern) somewhere on the ji-hada, ji-gane, or hamon.  Refer to Chapter 15, Revival of Yamato Den.   Masame is sometimes mixed with mokume (burl-like pattern) or itame (wood-grain-like pattern).  Either way, Yamato-den always shows masame somewhere.  Some swords display masame across the entire blade, while others show less.  Because of the masame, the hamon often shows sunagashi (a brush stroke-like pattern) or a double line called niju-ha.

This is a detailed section of Chapter 14| Late Kamakura Period Sword.  Please read Chapter 14 before this part.

14 Ikubi kissaki Damadge

In Chapter 14, “Late Kamakura Period Sword (鎌倉末太刀),” the ikubi-kissaki sword is explained.  The illustration above shows a flaw caused when the damaged area was repaired.  To compensate for this flaw, swordsmiths developed a new sword style during the late Kamakura period.  They forged swords with a longer kissaki and lowered the tip of the hi below the yokote line.   This way, if the yokote line were lowered during repairs, the tip of the hi would remain below the yokote line.

The above photo shows a sword by Goro Nyudo Masamune (五郎入道正宗).  Please observe the size and shape of the kissaki.  This differs from the previous ikubi-kissaki and ko-gissaki stylesThis style represents a typical late Kamakura period kissaki style.  It is o-suriage (a largely shortened form). 

Under the Kamakura Bakufu, many swordsmiths moved to KamakuraThey were Toroku Sakon Kunituna (藤六左近国綱) of the 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), emergedIn the drawing above, kinsuji and inazuma are shown within the hamon.  The shining lines inside the hamon are inazuma and kinsuji.  Inazuma and kinsuji are collections of nie.  Masamune is well-known for his inazuma and kinsuji.  He lived in Kamakura, a seaside town, and his hamon resembles ocean waves when viewed from the side.

The picture above shows a sword made by the swordsmith Yoshioka Ichimonji group (吉岡一文字).  The kissaki resembles one of Masamune’s swordsIt is longer than the previous ikubi-kissaki or ko-gissaki.  This is chu-gissaki.  The kissaki, like this, is one of the key points in determining the period when the sword was made.  The hamon has choji, gunome, togariba (pointed tip), and very tight nie.

The photo above shows a sword by Ukai Unsho (鵜飼雲生) from Bizen-den.  This sword is also from the late Kamakura period, but it has a ko-gissaki.  This sword does not have the late Kamakura period chu-gissaki style.  Narrow hoso-suguha are more characteristic of an earlier time than the late Kamakura periodThis sword indicates that swords do not always exhibit the style of their period.  To kantei*: first examine the style and shape, then give yourself an idea of the period it was made in.  However, the kissaki in this case does not indicate the late Kamakura period.  The next step is to look at the various characteristics of the sword one by one, such as the hamon, nie or nioi, ji-hada, etc., to determine the period, the den, and the province, and then come up with the name. This process is called kantei.

*Kantei – the process of identifying a swordsmith’s name by analyzing the sword’s characteristics without seeing the mei (the inscribed smith’s name).  The mei might be gone if it has been shortened.   All the photos above are from the Sano Museum Catalogue.  Permission to use them is granted.
