Antique Japanese Sword Tanto Signed by Rai Kunimitsu with NBTHK Tokubestsu Hozon Certificate

【Description】

 This blade was signed by Rai Kunimitsu (来国光) who was active during the late Kamakura- early Nanbokucho period (1326-1351). He belonged to Rai school, which was prosperous in Yamashiro province (Kyoto prefecture) during the mid-Kamakura-Nanbokucho period. Rai Kunimitsu was the second son of Rai Kunitoshi, and he was also known as Jiro Hyoueno Jo. Rai school was originally founded by Rai Kuniyuki and was taken over by Rai Kunitoshi, and then Kunimitsu became the head of the school in his career.

 Three of his signed works are designated national treasures of Japan, and 22 swords are classified as Important Cultural Property.

 Yamashiro province was famous for its sword making style called YAMASHIRO-DEN. YAMASHIRO-DEN’s origin dates back to the Heian period (794 A.D), when the capital city was moved from Nara to Kyoto. The swordsmiths in Yamashiro province initially prospered by forging swords for court nobles and imperial families. Later on, they also forged swords for feudal lords after Samurai military government took control of Japan. There are so many renowned swordsmiths from this region.

 It is said that the founder of YAMASHIRO-DEN was Sanjo Munechika. And there are seven prestigious schools in this region. One of them is Rai school, where Kunimitsu belonged. Rai school and Aawata school are the most prestigious ones among YAMASHIRO-DEN. One of the most characteristics of YAMASHIRO-DEN is its elegant design and beautiful Jigane. This blade represents strong trait of YAMASHIRO-DEN. 

 

 This blade is appraised as a Tokubetsu Hozon Token(特別保存刀剣) 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, especially well preserved and high quality with artistic value. 

 

*Please keep in mind that there is a minor Kitae Kizu on the blade. If you like to know the detailed condition, please feel free to contact us.

Kissaki: Kissaki is the tip of the Japanese sword.

 

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), Tsuba(Handguard).

 

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

*Please keep in mind that the black lacquer is partially missing on the Fuchi. We will be happy to have it restored before shipping it to you. We would like you to keep in mind that there might be trace of restoration.


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

 The theme of the Menuki and Kozuka is Botan (牡丹, peony) flower and Karajishi (唐獅子). The combination of Botan and Karajishi is called  Karajishi Botan (唐獅子牡丹).

 Peony represents happiness, wealth, nobleness, and gorgeousness. This flower pattern has been treated as a good-omen motif; people regarded it as a rich harvest sign. As mentioned above, a peony is called the Botan in Japanese. When we write this flower’s name in Kanji characters, its second letter means mountain hermit medicine that would give us eternal youth. Based on the meaning of this letter, the peony pattern symbolizes eternal youth and longevity.

 About the Karajishi, the Shishi (獅子) means a lion in Japanese, and the Karajishi is a lion brought from the Continent to Japan in the Toh period (唐, Tang dynasty, 618-907). The Karajishi typically has curly hair for its head, neck, body, and tail. In Buddhism, the Karajishi is regarded as a symbol of wisdom, and the Monju Bosatu (文殊菩薩, Manjushri Bodhisattva) rides lions. According to a theory, the Kara-Jishi originates from the Komainu (狛犬, stone guardian dogs that exorcize evil spirits). There is a Houwa (法話, Buddhist monks tell the story of Buddhism in an easy-to-understand manner) that treats the Karajishi and this flower. The lion is called the king of the beasts. However, even this invincible animal has only one fear: a bug in the lion’s body. This pest grows in the lion’s hair and eventually breaks the skin and bites the flesh. Nevertheless, it dies if it is exposed to the night dew of a peony. Therefore, the lion rests under peony flowers at night, looking for a haven. The design of these sword mountings might have been quoted from this story.

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

 A family emblem is designed on this Habaki. This type of the family crest is categorized as Yotsume Bishi (四ツ目菱). Yotsume means Four eyes in Japanese. This name comes from the fact that there are four dots in each square shape in this family crest. Bishi is a water chestnut. Initially, this pattern was used for kimonos when dyeing fabric in ancient times. One of the most famous feudal lords who used this family crest is the Takeda family, who took control of Kai province (Today’s Yamanashi prefecture) during the Sengoku Jidai (Warring state period). Two parts are connected to make the openwork of this family crest more visible.

 

KozukaKozuka is a small knife stored in Kozuka Hitsu(groove of the sheath of the Japanese sword).

Saya Saya is the scabbard for the Japanese sword.  

Authentication PaperNBTHK Tokubetsu Hozon Certificate for the blade (No. 1003452)

 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. They authenticated the blade on March 26th in the 27th year of Heisei  (2015). They appraised it as Tokubetsu Hozon Touken, the blade especially worth preserving for Japanese society. The purchaser will receive this original certificate as well. We can also translate what is written into English and make a PDF file for your record if you request.
