Antique Japanese Sword Tanto attributed to Masakatsu with NBTHK Hozon Certificate


 This Tanto is attributed to Mito Masakatsu (水戸正勝). He is also known as Katsumura Masakatsu. He started to study sword-forging techniques from Mito Tokukatsu when Masakatsu was just ten years old in 1849. They were originally from Mito province (Today’s Ibaraki prefecture). And, Tokukatsu and Masakatsu moved to Edo city when Masakatsu was 16 years old. And, Masakatsu learned superb craftsmanship from Hosokawa Masayoshi, Koyama Munetsugu, and Ishido Korekazu, who were renowned swordsmiths at the end of the Edo period.

 Masakatsu and his original master Tokukatsu had a close relationship throughout their career. And it is said that Masakatsu did a Daisaku for Tokukatsu at the end of Tokukatsu’s career. Daisaku is a regular act where an apprentice or a child of the swordsmith signs his master’s name with his master’s permission or forges a blade on behalf of the master. That means that his master highly acknowledged Kunitomo’s craftsmanship.

 In the second year of the Meiji era (1869), Masakatsu moved back to Mito domain and became a Hanko for Mito domain. Hanko is a swordsmith who exclusively forged swords for a specific clan.

 The structure of this Tanto is worth mentioning. While one side is made as Hirazukuri and the other side has Shinogi Zukuri. This difference makes this Tanto more interesting to appreciate.

 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.

Horimono: Horimono is an inscription or sculpture on Japanese swords. 

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. 

 This Koshirae’s Kashira and the Kojiri (鐺, a metal fitting that protects the tip of a scabbard) have the same design: the wave pattern. Dynamic movements of waves are meticulously carved on silvery metal fittings. 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. The wave pattern is also incorporated into the decoration of other parts described later, and it could be said that it is one of the themes that leads to the overall appearance of this Koshirae.

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

 This Koshirae’s Menukis have small round shapes and are colored with golden paint. Same as the Fuchi Kashira and Kojiri, the wave pattern is designed on one side of the Menuki. On the other hand, you would find two birds are engraved on another Menuki. This Menuki’s design is completed by combining these two patterns (waves and bird patterns); the Nami Chidori (波千鳥). The Nami Chidori pattern represents happy marriage and family safety. In Japan, people have treated it as a good omen design since the Nara period (648-781). Nami (波) means waves, and Chidori (千鳥) means plovers in Japanese. Waves are compared to the world, meaning it describes the determination: overcoming difficulties with a partner even if there are small or big waves (difficulties/ troubles). Also, the plover pattern is used as a prayer for victory or achieving a goal.

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

KougaiKougai is the equipment for Samurai to arrange or fix his hair style

 This item is an antique Kougai (笄), which was used to arrange or fix the hairstyle of Samurai. Horizontal stripes are engraved on this Kougai to enhance its decorativeness. The Kougai is usually stored in the Kougai Hitsu (笄櫃). The Kozuka (小柄) is often stored on the other side of the scabbard. This Kougai is separated into two parts; this type of Kougai is categorized as the Wari Kougai (割笄). This separated type was invented in the Edo period and became popular as decorative metal fittings. There is no proof but a theory says some people used the Wari Kougai as chopsticks.

Saya Saya is the scabbard for the Japanese sword

 The entire surface of this scabbard is decorated with a geometric pattern, and we believe this is a kind of cloud design. Clouds bring rain and snow, and their movements significantly affect the day’s weather. Due to its supernatural power, a theory says that gods, spirits, and dragons dwell in the clouds. Since the cloud pattern has been associated with magical power, people thought it an omen of lucky things. This idea might have inspired this Saya Nuri (鞘塗, scabbard painting).


Authentication PaperNBTHK Hozon Certificate for the blade (No. 330685 )

 NBTHK, also known as Nihon Bijutsu Touken Hozon Kyokai (the Society for the Preservation of the Japan Art Sword), is one of the oldest Japanese sword appraising organizations in modern-day Japan.
