Antique Japanese Sword Tanto Signed by Yokoyama Sukekane with NBTHK Hozon Certificate


 This blade was signed by Bizen Osafune Jyu Yokoyama Sukekane(備前長船住横山祐包) in the 5th year of the Ansei era(1858: Bakumatsu era). He signed the 58th grandson of Tomonari on the tang as well. Tomomori was a renowned swordsmith in the mid-late Heian period in Bizen province(today’s Okayama prefecture). We presume he signed it to be proud of his ancestry. Bizen Osafune Jyu means that he resided in this area in today’s Okayama prefecture. Osafune is also the name of the school Sukekane belonged to. Yokoyama was his last name.

About Bizen Osafune

 Sukekane’s ancestors dated back to Sukesada school, one of the most famous schools, and flourished for generations among Osafune schools(The head branch). There were various styles forged by the generations of Sukesada during the Muromachi-Edo period. There were about 60 swordsmiths who used Sukesada as his maker’s name in Samurai history. 

 The swordsmiths in Bizen produced many swords during the Muromachi period as it was in the middle of the Sengoku period(Warring state period). The demand for blades increased among strong feudal lords. The high level of craftsmanship had been passed until the end of the Edo period, and Sukekane is a good example.

 BIZEN is located near the Chugoku Mountains, where iron sands, one of the essential materials for making Japanese swords, were abundant. Furthermore, BIZEN swordsmiths had close access to Yoshi River, where they could find water and charcoal. This geological location contributed to the swordsmiths to forge high-quality refined blades. We presume BIZEN was quite active in sword-forging from ancient times. It is said that BIZEN DEN was created by groups of swordsmiths there after the late Heian era(Late 12th century ).

The Background History

 Japan enjoyed a relatively peaceful time from the early Edo period to the mid-Edo period(the 1600s-1760s) because of the stable economy and the powerful government run by Tokugawa Shogun. Samurai didn’t have many opportunities to utilize his Katana sword in public or on battlefields during this time. Thus, they carried their swords more as a symbol of their social status. The demand for weapons decreased accordingly compared to the previous Warring state period called Sengoku Jidai. (1467-1600)

However, toward the end of the Edo period(1764-1876), the Japanese sword’s role changed dramatically. With the poverty spreading in Japan, there were so many riots initiated by the civilians. Japanese sword started to play an essential role in maintaining public safety.

 Pressure from foreign countries to open Japanese borders also forced Samurai to order strong-looking swords to survive this tumultuous time. We believe many swordsmiths, including Sukekane, made great efforts to forged high-quality, practical blades for their masters to prepare for battles.

 There was a civil war between Tokugawa’s military government and the new Meiji government at the end of the Edo period. That means the original owner of this Tanto might have seen the moment when Samurai’s life changed forever. This blade has a strong looking and must have been practical to use in that demanding time. 

You can see Sukekane’s excellent craftsmanship by simply looking at this blade closely. We are confident you will be happy to own this piece of Samurai history. 


 This blade is appraised as a Hozon Token(保存刀剣) issued by NBTHK(Nihon Bijutsu Touken Hozon Kyokai:日本美術刀剣保存協会). This authentication paper was only given to authentic Japanese swords, well preserved with artistic value.

NakagoNakago is the tang of the Japanese sword.

Japanese swordsmiths left the black rust on the tang because it prevents red rust while the tang is in its handle. And the discoloration of the tang was created over time, and it is a great indicator for a Japanese sword specialist to estimate when the sword was forged.

Koshirae: Koshirae is the mounting of the Japanese sword. There are several parts that consist of Koshirae such as Saya(Scabbard), Tsuka(Handle), Kozuka.


Fuchi-KashiraA pair of matching sword fittings that cover the upper and bottom parts of its sword hilt. 

 You could find the signature of this Fuchi Kashira’s maker on the side of the Fichi part. It is written as Shufu-Ju (秋府住) Hondou Naonaga (本堂 直長). It means this work was done by Hondou Naonaga, who lived in the Shufu area.

 The wave pattern is engraved in semi-three dimensionally with strong carving lines. The rough movement of the waves creates an animated image. This motif is often seen in sword mountings and frequently combined with the dragon design. We estimate it is because of a belief that worships the dragon as a water god.

 As waves’ movements continue endlessly, the wave pattern represents eternity, immortality, longevity, birth, etcetera. Also, since tides repeatedly change the shape and terrain of rocks, some people hoped for a strong will by using this motif. People used this pattern wishing for an indomitable spirit to rechallenge time and time without giving up. Thanks to its dynamic design, this motif has been appreciated, especially for men’s Kimono (traditional Japanese costume).

Tsuka and MenukiTsuka is the handle of the Japanese sword and Menuki is its decoration.

 This Menuki is made from copper. It remains its classy color. We believe this Menuki’s design is a family crest. This plant pattern is categorized as the Kiri (桐, paulownia) motif, and is called the Gosan-no Kiri (五三の桐) design.

 The Kiri pattern is generally composed of three standing straight inflorescences and three leaves. The number of flowers blooming at each inflorescence shows the ranks of this design. It is also famous that one of the most popular Samurai in Japan: Toyotomi Hideyoshi (豊臣 秀吉, 1537-1598), used the Kiri pattern for his family crest. A theory says that Hideyoshi initially used the Omodaka (沢瀉, arrowhead) pattern as his family crest. However, Oda Nobunaga (織田 信長, 1534-1582), a well-known military commander in the Warring States period, permitted Hideyoshi to use the Kiri design. After the fall of the Muromachi Shogunate and the defeat of Nobunaga at the Honnouji (本能寺) temple, the reign of Hideyoshi finally started. Hideyoshi used this plant motif in various items such as clothes, furniture, decorations of his buildings, etcetera.

 Moreover, he bestowed the Kiri crests to his subordinates with the clan name Hashiba (羽柴, Hideyoshi used this family name before the Toyotomi clan) or Toyotomi (豊臣). However, even among Hideyoshi’s subordinates, this Kiri crest was often given as a reward. But some people began to use this family crest without permission, such as by borrowing or stealing it. In response to this situation, Hideyoshi enacted a law to limit the use of the Kiri crest, but the value of this design decreased considerably. Therefore, it is said that Hideyoshi used a unique design Kiri crest called the Taikou Giri (太閤桐) pattern to distinguish it from others. Through these processes, the Kiri crest became a familiar emblem not only for the privileged class, such as influential Samurai, but also for the middle class and the general public.

 This plant pattern was once used by the imperial family and national leaders of the time. Today, this plant pattern is used as the crest of the Japanese Government. We hope that by introducing a little about the transition of this family crest, you will find the history of this design and its deep connection with the Samurai culture fascinating. Please enjoy this sword’s Koshirae with its blade.

HabakiHabaki is the equipment to make the blade not touch its scabbard inside. It prevents the blade from getting rusty and chipped. 


Saya Saya is the scabbard for the Japanese sword.  

 This scabbard has a surface with a constant width notched pattern like an Inro (印籠, traditional Japanese case to store small objects) in the circumferential direction. This type of scabbard is categorized as the Inro Kizami Zaya (印籠刻鞘).
