After the Muromachi period, swords shifted to katana(刀) from tachi (太刀), as described in Chapter 21, Muromachi Period Sword.  Refer to Chapter 21, Muromachi Period Sword.  By the end of the Nanboku-cho period, sword lengths had shortened to about 2 feet ± a few inches.  The 3-to-5-foot-long swords seen during the Nanboku-cho period were no longer produced.  This change occurred because, during the Nanboku-cho period, warriors mainly fought on horseback, but after the Muromachi period, infantry combat became more common.

Oei Bizen (応永備前)                                                                                                              The pronunciation of Oei is “O” as in “Oh” and “ei” as in “A” from ABC.  The Muromachi period was a declining time for sword-making.  The swords made during the early Muromachi period in the Bizen area is known as Oei BizenOsafune Morimitsu (長船盛光), Osafune Yasumitsu (長船康光), and Osafune Moromitsu (長船師光) were the main Oei Bizen swordsmiths.  Soshu Hiromasa (相州広正) and Yamashiro Nobukuni (山城信國) were also similar to the Oei Bizen style.  Please refer to Chapter 21, Muromachi Period Sword, for details on the  Muromachi sword shape, Hamon, Boshi, and Ji-hada.

                       Bishu Osafune Moromitsu (備州長船師光)   from Sano Museum Catalogue ((permission granted)

The Osafune Moromitsu sword shown above measures 2 feet 5 inches in length and has a medium kissaki.  Its hamon has a small wave-like pattern with continuous gunome (a lined half-circle pattern).  The boshi area shows irregular waviness with a slightly pointed tip.  Very faint bo-utsuri (a soft shadow shaped like a strip of wood) appears on ji-hadaBo-utsuri is a distinctive feature among all the Oei Bizen

Before the Muromachi period, many swordsmith groups operated in the Bizen region. However, by the Muromachi period, Osafune (長船) was the only remaining group.

Osafune (長船) is the name of a region, but it became the surname of swordsmiths during the Muromachi period.  Two other well-known swordsmiths from Oei Bizen are Osafune Morimitsu (盛光) and Osafune Yasumitsu (康光).  The hamon created by Morimitsu and Yasumitsu is more detailed than that of the sword in the photo above.  Chapter 21, Muromachi period swords, shows the hamon of Morimitsu and Yasumitsu and describes the typical characteristics of swords from the Muromachi period.

Hirazukuri ko-wakizashi tanto was a popular style during the early Muromachi period. Swordsmiths from various regions produced tantos similar to the one shown above. However, most of these types were made by Oei Bizen swordsmiths.

The characteristics of the Hirazukuri ko-wakizashi tanto ————-Typically about one foot and 1 or 2 inches long.  No yokote line, no shinogi, and no sori (meaning no curvature, straight back).  Average thickness.  Narrow width.  Gyo-no-mune (refer to Chapter 12, Middle Kamakura Period Tanto).

This chapter is a detailed part of Chapter 15, Revival of Yamato Den.  Please read Chapter 15 before reading this section.

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.

19 | Nanboku-Cho Period Tanto(南北朝短刀)

0-timeline - size 24 Nanboku-cho
The circle indicates the time we discuss in this section

During the Nanboku-cho period, a type of tanto called hirazukuri ko-wakizashi sun-nobi tanto was made.  Hirazukuri means flat swords without the yokote line or shinogi.  Ko-wakizashi refers to a shorter sword.  Sun-nobi tanto means longer than a standard tanto.  This type is also known as Enbun Jyoji ko-wakizashi tanto because most of these tantos were created during the Enbun and Jyoji eras of the imperial period.  In Japan, a new imperial era begins when a new emperor ascends to the throne.  The Enbun era spanned 1356-1361, while the Jyoji period spanned 1362-1368.

20 Enbun Jyoji Kowakizashi Tanto

Sugata (姿: shape) ————A standard tanto measure is approximately one shaku.  Shaku is an old Japanese unit of measurement for length, and one shaku is roughly equal to one foot.  

8.5 sun (the sun is another old Japanese measurement unit of length) is approximately ten inches.  Ten inches is the standard size for a tanto, known as a josun tanto.  Anything longer than a josun tanto is called a sun-nobi tanto.  Anything shorter than a josun is called a sun-zumari tanto. 

Most of the Nanboku-cho tantos are longer than a josun tanto, approximately one foot two inches.  Therefore, they are called hirazukuri ko-wakizashi sun-nobi tantoSaki-zori (curved outward at the top.  See the illustration above).   Wide in width and thin in body.  Fukura kareru (no fukura means less arc).  Shin-no-mune.  See the drawing below.

20 Fukura           20 Shin-no-Mune

Hi, (: Grooves) and Horimono (彫り物: Engraving) ——- A groove or grooves on the mune side.  Bonji (Sanskrit, see Chapter 16 Late Kamakura Period (Early Soshu-Den Tanto),  koshi-bi (short groove),  tumetuki ken, and tokko-tsuki ken (see below) appear. The ken (dagger) is curved widely and deeply in the upper part and shallower and narrower in the lower part.  This is called Soshu-bori (Soshu-style carving).

20 Tokko, tume Ken

Hamon (: Tempered line) ——- The narrowly tempered section at the lower part gradually widens toward the top.  A similar wide hamon pattern extends into the boshi area.  The hamon in the kissaki area is kaeri-fukashi (deep turn back).  See the illustration below.  Coarse nie.  O-midare (large irregular hamon pattern).

20 Hitatsura

                                        From Sano Museum Catalogue

Ji-hada (地肌: the area between shinogi-ji and the tempered line) ——– a loose wood grain pattern called itame.  Yubashiri (see Chapter 16, Late Kamakura Period) and tobiyaki (irregular patchy tempered spots) appear.  Dense tobiyaki is called hitatsura (see the drawing above).

Nakago (: Tang) —- Short tanago-bara.  Tanago-bara refers to the shape of the belly of a Japanese fish called tanago (bitterling).

0-timeline - size 24 Middle Kamakura

The red circle indicates the area we discuss in this chapter 

It is rare to find a tanto (短刀 dagger) made during the Heian period.  During the middle Kamakura period, many high-quality tanto were produced.  They were called takenoko-zori shaped tanto, with “takenoko” meaning bamboo shoot.  The back of the tanto curves inward slightly.

12Tanto drawing Mid Kamakur

Sugata (shape)———-Hirazukuri.  This means there is no shinogi, no yokote line.  See the illustration above.  The standard tanto length is approximately ten inches.  The width is neither too wide nor too narrow, making it well-proportioned.  The body is slightly thick.  High gyo-no-mune (行の棟) and shin-no-mune (真の棟).

Hamon (刃文) ——————— The tempered area is narrow.  Nie base.  Suguha-midare (a straight-line pattern with an irregular wavy shape) or suguha-choji (a straight-line pattern with small choji)The tempered edge line may display a frayed pattern.

Boshi(tempered line at Kissaki area) ———Yakizume,   Kaen,   Nie-kuzure.

13 Hamon and Hi

Engravings (彫刻) ———- Often, various types of engravings are applied to the lower part of the body.   These may include one or two grooves, Sanskrit, suken (spear), dragon, etc.  For the Sanskrit and spear, refer to the illustration in Chapter 8.
