Antique Japanese Sword Katana Signed by Sadakuni with Tokubetsu Hozon Certificate
This blade was signed by Sunpu Anzai Jyu Sadakuni (駿府安西住貞国), who was active during the early Edo period (Kanbun era:1661-1673). He belonged to Shimada school, a prestigious school located in Suruga domain (Today’s Shizuoka prefecture). Sunpu is another name for Suruga Domain. Anzai is the name of the town he lived.
Shimada school was founded by Yoshisuke (義助) during the mid-Muromachi period and lasted by the late Edo period. The group of Shimada swordsmiths resided in Shimada city, Suruga province (today’s Shizuoka prefecture). Other famous swordsmiths from this school are Sukemune, Hirotsugu, and Sadahiro.
The first-gen Yoshisuke was active during the Kosho era(1455-57). It is said that the first-gen Yoshisuke was a descendant of Bizen Ichimonji Sukemune, one of the most famous swordsmiths in Japanese history. The first-gen Yoshisuke served a powerful feudal family named Imagawa. It is said that he received his maker’s name 義 from Imagawa Yoshitada.
Shimada school interacted with other schools in Soshu swordsmiths living near Odawa castle in Kanagawa prefecture. The Suruga domain was vital for strong feudal lords such as Takeda, Tokugawa, and Hojo clans during the Sengoku Jidai (Warring state period: Late Muromachi period). The swordsmiths in Shimada school received many orders from these powerful feudal families. The first-gen Yoshisuke had mastered excellent craftsmanship, and it was passed down to other members of Shimada swordsmiths. And the school flourished during the Muromachi-Edo period.
This blade also has a beautiful Horimono(engraving) of Kurikara Ken. Kurikara-Ken (倶利伽羅剣) is the sword that Fudo Myo-O (不動明王, acalanātha) holds with his right hand. Fudo Myo-O is one of the objects of worship in Buddhism. According to a theory, it is the incarnation of Dainichi Nyorai (大日如来, Mahāvairocana, the principal image of esoteric Buddhism).
Kurikara-ken was named due to the appearance that Kurikara Ryu-O (倶利伽羅龍王, dragon) is winding around the sword. It is believed that Kurikara-Ken could cut off worldly desires: Sandoku (三毒). Sandoku is the three fundamental earthly desires; Ton (貪, greed), Jin (瞋, anger, grudge), and Chi (癡, delusion, complaint).
It 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.

Nakago：Nakago 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-Kashira：A pair of matching sword fittings that cover the upper and bottom parts of its sword hilt.
This Fuchi Kashira is decorated with dragon designs. Golden paint is applied to these dragons and makes an elegant color contrast with black and gold. Even each scale is meticulously sculpted, and they are depicted with a realistic expression.
Initially, the dragon is an imaginary creature found in ancient Chinese traditions or myths. Furthermore, it is regarded as a symbolic beast of auspicious signs. Its body is likened to nine animals: antlers are deer, the head is a camel, eyes are demons, the neck is a snake, the belly is the Mizuchi (蛟, a mythical animal in Japan that looks like a snake and has a horn and four legs), scales are fish, claws are falcons, palms are tigers, and ears are cows. It was thought that the dragon would reign at the top of all animals because of its odd-looking appearance. The dragon design is often seen in sword mountings. It shows that many Samurai favored this dignified beast motif.
Tsuka and Menuki：Tsuka is the handle of the Japanese sword and Menuki is its decoration.
This Menuki’ motif is the Yadutsu (矢筒, quiver). A number of arrows are stored in a quiver, which is painted with gorgeous plant patterns in gold.
It is the storage case for storing arrows. Before guns were used on battlefields, bow and arrow tactics were one of the primary weapons for Samurai warriors. As an arrow goes straight forward powerfully, lots of Samurai loved the arrow pattern. This design would have been evocative of battlefields for Samurai, and they might have adopted such a design to encourage themselves.
Additionally, in Japan, there is a custom that each home displays decorated arrows wishing that it would exorcize evil spirits in the house. This talisman is called the Hama-Ya (破魔矢) in Japanese, and this custom is still kept today. This kind of idea also might have inspired the idea of incorporating arrow-related motifs for Japanese swords decorations.
Tsuba and Habaki：Tsuba is the handguard for the Japanese Sword and Habaki is the equipment to make the blade not touch its scabbard inside. It prevents the blade from getting rusty and chipped.
Oval-shaped Tsuba that has Kozuka and Kougai holes. Same as the Fuchi Kashira, the dragon is the principal motif of this Tsuba. 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.
In Japan, a religion worships the dragon as a water god. Since rice cultivation has flourished in this country, water has always been an essential resource. The power of clouds that bring blessed rain was possibly associated with the idea of the combination of dragons and clouds. And it might be one of the reasons why this combination design is often seen even in sword mountings.
Saya： Saya is the scabbard for the Japanese sword.
Authentication Paper：NBTHK TOKUBETSU Hozon Certificate for the blade (No. 1013272)
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.
