20 Enbun Jyoji Kowakizashi Tanto

The drawing above shows a typical shape of a Nanboku-cho-period tanto. This drawing was in Chapter 19.  I exaggerated the features of the Enbun Joji ko-wakizashi tanto to better show you.  At the end of Chapter 19, Nanboku-cho Tanto, there is a list of swordsmiths’ names from that period.  Hiromitsu (広光) and Akihiro (秋広) represent the Nanboku-cho style.

Enbun Joji Ko-wakizashi tanto is also called Sun-nobi tanto (>10 inches) because its length is longer than the standard size (about 10 inches) tanto.  The upper part of the tanto curves outward slightly.  This type is called sakizori.

Characteristics of Hiromitsu (広光) and Akihiro (秋広)

  • Shape———————— Usually, one foot and one to two inches long (Sun-nobi).   Wide width.  Thin blade.  Sakizori.
  • Hamon ———————- A mix of wide and narrow hamon.  The hamon around the yakidashi (just above the machi) area is narrow but gradually widens as it moves up.  The hamon around the fukura area shows most work.  Mainly nie.  Sunagashi, kinsuji, gunome, umanoha-midare (horse teeth-shaped hamon), or hitatsura appear (drawing above).                 
  • Boshi———-Irregular and unevenly tempered.  The hamon covers almost the entire boshi. Deep turn back. 
  • Jihada ———————————————————Wood-grained pattern
  • Nakago —————–Tanago-bara shape.  Refer to 19 Nanboku-cho Period Tanto.

Nobukuni (Below is my sword)

Shodai Nobukuni (the first-generation Nobukuni) was a student of Sadamune.  He was one of the Sadamune San Tetsu (貞宗三哲, Sadamune’s top three students).  Nobukuni’s characteristics resembled those of Hiromitsu and Akihiro, as described above.  Nobukuni also created sun-nobi tanto.  The sword below has a hoso-suguha, ko-mokume (small burl pattern), and ko-maru boshi (small round).

50|Part 2 of –16 Late Kamakura Period: Tanto (Early Soshu-Den 鎌倉末短刀, 正宗墓)

Chapter 50 is a detailed part of  Chapter 16, Late Kamakura Period Tanto (Early Soshu-Den).  Please read Chapter 16 before this section.

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

In  Chapter 16, Late Kamakura Period Tanto (Early Soshu-Den), the general features of the late Kamakura period tanto style (early Soshu-den) are described.  The following two photos show the typical characteristics of early Soshu-den tanto.

Masamune

Goro Nyudo Masamune (五郎入道正宗) was born in Kamakura as the son of Tosaburo Yukimitu (藤三郎行光)Today, Masamune is a well-known swordsmith, even among those unfamiliar with Japanese swords.  His father, Tosaburo Yukimitsu, was also among the top swordsmiths in early Soshu-den.  Masamune’s tomb is located at Honkaku-ji (本覚寺) Temple, about a 6-minute walk from Kamakura Station. 

Goro Nyudo Masamune (五郎入道正宗) Sano Museum Catalog (permission granted)

Masamune photo (above) —– Hira-zukuri (flat).  Sakizori is very slightly curved (the tip area curves slightly outward).  Bo-hi and tsure-hi (parallel thin grooves).  Komaru-boshiItame-hada (wood grain pattern).  The Hamon is notare (wavy).  The illustration above shows sunagashi and niju-ba (double hamon).  This type of nakago is called tanago-bara.  The Masamune tanto is often mu-mei (unsigned). This particular tanto is called Komatsu Masamune (小松政宗).  The catalog from the Sano Museum’s description stated that connoisseurs in the past had difficulty determining this as a Masamune swordBecause the wide mihaba with sori and hamon slightly differed from those of another Masamune.  Judging from the clear nie, chikei, and kinsuji, it was determined to be a Masamune tanto.

Enju Photo below

               Higo Province Enju Kunisuke from Sano Museum Catalog (permission granted)

The Enju (延寿) group lived in Higo (肥後) Province on Kyushu.  The characteristics of the Enju group closely resemble those of the Yamashiro-den because Enju Kunimura was related to Rai Kuniyuki, a member of the Yamashiro-den.

Enju (photo above) —-Hamon is hoso-suguha (straight temper line).  The boshi is komaru.  The front engraving is suken (above left photo, left side), and the engraving on the back is gomabashi (left photo, right side).  Tight itame ji-hada.  It can be confusing to kantei (determine who made the sword) a sword like this because, although it is from the late Kamakura period, it does not have the typical early Soshu-den appearance.

Masamune’s Tomb in Honkaku-ji Temple

Masamune’s (正宗) tomb is located inside Honkaku-ji Temple (本覚寺) in Kamakura.  Here is a map of Honkaku-ji Temple and the Masamune Kogei store in Kamakura.  The store is owned by Tsunahiro Yamamura, the 24th generation of MasamuneHonkaku-ji Temple is circled on the map, and the Masamune Kogei store is a red circle with an X.  Both are about a 6 to 7-minute walk from Kamakura Station. 

To reach to Honkaku-Ji Temple from Tokyo                                                                           Take the Yokosuka Line train from Tokyo Station (approx. one hour) → Get off at Kamakura Station (one stop after Kita-Kamakura) → Exit through the East Exit (front exit) → Walk straight and cross the street → Turn right and walk to the post office → Turn left at the post office (Honkaku-ji Temple sign is at the corner of the post office)

3Musashi ( 武蔵 ) in Edo ( 江戸 )

The katana and wakizashi made in the Musashi area have a shallow sori (curvature).  Often, the width of the blade’s upper part is narrow.  Usually, the hamon begins with a slight irregular pattern, then gradually shifts to a larger irregular pattern, and a few inches below the yokote line, it becomes a small irregular pattern again.  The boshi is usually a komaru-boshi.  The ji-hada may be rough.  Masame-hada shows on shinogi-ji.

4. Echizen ( 越前 ) and 5. Kaga (加賀 )

Many swordsmiths from the Mino (美濃) area moved to the Echizen and Kaga areas (#4  & #5 on the map above).  Therefore, swords made in these areas are called Echizen-seki and Kaga-seki.  Refer to Chapter 23 Sengoku Period (戦国) Sword for Mino-den.             The style of Echizen Yasutsugu (越前康継) is similar to that of Mino-den.

Well-known swordsmith in Echizen ————————-Echizen Yasutsugu (越前康継 )

6. Hizen (肥前)

Both the katana and wakizashi from Hizen have well-balanced shapes.  The Hizen region tends to produce swords with a chu-suguha-hotsure (a medium-width straight hamon resembling frayed fabric) with fine nie (沸).  The boshi has a clean, regular line with a uniform width tempered line, as shown in the illustration below.  If you see a shin-to sword that has a chu-suguha hamon and a boshi that looks like the one below, it is often made by Hizen Tadayoshi (肥前忠吉).  Very fine Ji-hada (surface), sometimes called nukame-hada.

  1. Satsuma (薩摩 )

The swords made in Satsuma appear solid for both katana and wakizashi.  The kissaki (the top pointed area) is slightly stretched.  Yakidashi (a few inches above the machi ) shows a small, irregular hamon.  The hamon is o-midare with coarse nie called ara-nie. The ara-nie forms togari-ba (a pointed pattern; see the drawing below)One of the characteristics of this region.

The region is well known for its Satsuma-nie.  That is, the ara-nie around the hamon continues and blends into the ji-hada area.  Therefore, the border between ha-nie and ji-nie is unclear.  Inside the hamon, it sometimes shows a thick line shaped like lightning.  This line is called Satsuma-no-imozuru (sweet potato vine), and is less desirable than inazume and kinsiji.  This is the most prominent feature of the Satsuma sword.  Boshi has a narrow-tempered line with a small irregular patternThis is called satsuma-boshi.  On the ji-hada surface, chikei (a long, dark line) appears.  This is called Satsuma-gane (薩摩金).

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).
