Chapter 27, Shin-to Main 7 Regions (Part A), and Chapter 28, Shin-to Main 7 Regions (Part B), describe an overview of the seven main regions.  This chapter and the next chapter show photos of representative swords from these regions.  They are Yamashiro (山城, in Kyoto), Settsu (摂津, today’s Osaka), Musashi (武蔵, Edo), and Satsuma (薩摩, Kyushu).  However, Echizen (越前), Kaga (加賀), and Hizen (肥前) are omitted.

29 Map with number 7

With ko-to swords, features such as the condition of the hamon, kissaki size, length, and  shape of the nakago, etc., indicate when the sword was made.  During the ko-to period, Bizen swordsmiths produced Bizen-den swords, Yamashiro swordsmiths made Yamashiro-den swords, and Mino swordsmiths made Mino-den swords.  However, during the shin-to period, that is not the case.  The den and the swordsmith’s location often do not match.  For shin-to swords, we study the swordsmiths and swords from the seven main regions along with their characteristics.

Regarding swords made during the ko-to period, if a sword has a wide hamon line with  nie, usually, its ji-hada shows a large wood grain or a large burl grain.  Also, when you see a narrow hamon line, it typically features a fine ji-hada.

However, with shin-to swords, if a sword shows a wide hamon with nie, it often has a small wood grain or small burl grain pattern on ji-hada.  If it has a narrow hamon line, it may have a large wood grain pattern on the ji-hada.  This is a shin-to characteristic.   

Here is an exception: some early Soshu-den swords from the late Kamakura period may show a wide hamon with nie, which has small burls on the ji-hada.  Because of that, whether it is ko-to or shin-to can be confusing.  Even so, other features such as ji-hada or other parts should indicate whether it is shin-to or ko-to.

Horikawa Kunihiro (堀川国広)

Horikawa Kunihiro was regarded as a master swordsmith among shin-to swordsmiths.  He forged swords in many styles with various characteristics.  The hamon types are o-notare, o-gunome, togari-ba (pointed hamon), chu-suguha with hotsure (frayed look), hiro-suguha with a sunagashi effect, inazuma, and kinsujiKunihiro preferred to shape his swords to resemble an o-suriage (shortened Nanboku-cho style long sword).  Kunihiro‘s blades give a powerful impression.  Kunihiro‘s swords often feature beautiful carvings; designs include dragons, Sanskrit letters, and more.  Because he created swords in many different styles, there is no general characteristic that defines his work other than the hamon mainly being nie.  His ji-hada is finely forged.

The Swordsmith for Tanto during the Sengoku Period 

The Bizen swords from the Sengoku period are called sue-bizenSue is pronounced “su” and “e“ as in egg.   Bizen Osafune Yoso-Zaemon Sukesada (与三左衛門祐定) is the most famous swordsmith of the Sengoku period.  He also forged tantos.  One thing to note is that many swordsmiths had the name Sukesada.  Yoso-Zaemon Sukesada is the one who best represents the era.
