The Muromachi period was a relatively peaceful and prosperous time until a little before “Onin-no-Ran,” which happened at the end of the Muromachi PeriodRefer to Chapter 20|Muromachi Period History (室町時代歴史) .  The Nanboku-cho style long sword became useless; thus, they were shortened.  The shortened blade is called Suriage.  In general, the Muromachi period was the declining time for sword making.

Tachi and Katana

Until the end of the Nanboku-cho period or the beginning of the Muromachi period, Samurai suspended swords from one’s waist, the blade side down.  When a sword was worn this way, the swordsmith inscribed his name to the side that faces outward, which means that the blade comes on your right when you see the inscription.  In this case, the sword is called Tachi.

Yet, around the Muromachi period, a sword was worn between one’s belt, with the blade side up.  The swordsmiths inscribed his name to face outward when it was worn. Therefore, when you see the inscription, the cutting edge comes on your left.  Then it is classified as Katana. 

Around the beginning of the Muromachi period, Samurai started to wear a pair of swords called Dai-sho (大小), meaning large and small.  The long one is Katana, and the short one is Wakizashi.  In general, Tachi is longer than Katana.  Katana is longer than Wakizashi, and Wakizashi is longer than Tanto.  Here is the order of the length. 

                                       Tachi   >   Katana   >   Wakizashi   >  Tanto

The difference between Tachi and Katana comes from the way it was worn, not the length.   22 tachi & Katana

O-suriage ( 大磨上: Katana shortened by great length) 

How much the sword should be shortened depends on the sword’s original length and how much the owner wants it shortened.  O-suriage is a kind of sword that is shortened by a great length.  Once a blade is shortened that much, the inscription of the maker’s name is cut off.  When Hon’ami family (本阿弥家, a sword connoisseur family who have appraised Japanese swords for generations since the Muromachi  period till today) appraised such a Suriage sword, they wrote the make of the sword and the swordsmith’s name on the front side of the hilt, and the connoisseur’s name with his Kaou (similar to signature) on the back.  There are several ranks of writings.  Which level it should be done is depending on the quality of the sword and how an owner wants it.  Below are the classes (lower to highest).

Shu-Mei (朱明 )————————————————————-name written in Vermilion  Kinpun-Mei (金粉名 )———————————————–name lacquered in gold powder  Gin-Zougan (銀象嵌 )————————————————————name inlaid in silver  Kin-Zougan (金象嵌 )————————————————————-name inlaid in gold

Sugata (姿: Shape)———— The average length is usually  2 feet and 3 to 4 inches (68~71cm).  The shape of the Muromachi period Katana is somewhat similar to the Heian period Tachi style.  However, Muromachi Katana is not as grand or graceful as the Heian period sword.  The curvature is usually the Koshizori shape.  Koshizori means the highest curvature comes at the lower part of the blade.  The length and shape are suitable for wearing between the body and the belt. The width and the thickness are well balanced with the size of the sword.  Small Kissaki.

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.
