Antique Japanese Sword Wakizashi Signed by Tsunahide with NBTHK Tokubestsu Hozon Certificate
【Description】
This blade was signed by Kato Tsunahide (加藤綱英) in the 12th year of the Bunka era (1815) . His birthname was Kato Suketaro. He first signed Kunitsuna and changed it to Tsunahide. Tsunahide worked as a swordsmith under the prestigious Uesugi family (上杉家) and was the older brother of Chounsai Tsunatoshi (長運斎綱俊). He was the first son and Tsunatoshi was the third son. Tsunahide forged blades in in Dewa Province (today’s Yamagata province). And, it is said that he also resided in Edo city from the 3rd year of the Bunka era to 13th year of the Bunka era (1806-1816). Considering this record, we believe this Wakizashi was created in Edo.
He is also famous for being the master of the renowned Bizen-den swordsmith, Koyama Munetsugu (固山宗次). His blades are characterized by the distinctive “Toran-midare (濤瀾乱)”, where the surface of the Hamon has a beautiful wave-like pattern, reminiscent of crashing waves.
Chounsai Tsunatoshi and Tsunahide
Tsunatoshi was born in 1798 in Yonezawa city, Hashu province (Yamagata prefecture) as the third son of Izumi no Kami Kunihide(和泉守国秀). His family name was Kato, and he was the younger brother of Kato Tsunahide (加藤綱英). Tsunatoshi’s real name was Kato Hachiro.
Tsunahide and Tsunatoshi served Yonezawa Uesugi clan, a powerful feudal lord in today’s Yamagata prefecture.
During their early career, they moved to Edo city to learn superb sword-forging techniques from Suishinshi Masahide, one of the most renowned swordsmiths at the end of the Edo period. There is also a record of Tsunatoshi forging swords in Osaka and Kumamoto while his base was in Azabu town in Edo city (Today’s Tokyo).
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.
【Blade】
Cutting Edge Length(Nagasa)：38.5 cm (15.1 inches)
Curvature(Sori)： 0.6 cm (0.23 inches)
Hamon：
The crystalline structure which forms along the cutting edge of a blade as a result of the hardening process
Jimon(Jihada)：
visible steel surface pattern created by folding and hammering during forging process
Kissaki：Kissaki is the tip of the Japanese sword.
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.
The theme of the Fuchi-Kashira is war. One side features a Hata-jirushi (military banners used during the Sengoku period) set against the backdrop of rough waves and pine trees, while the other side depicts a Samurai fighting on a boat.
As pine trees keep their green color throughout the years by withstanding severe heat and cold, people thought this plant pattern represents eternal youth. Furthermore, its color is called Tokiwa-Iro (常盤色, evergreen trees’ dark green color with brown), and pine trees have another name “Tokiwa-Gi (常盤木).” Tokiwa means immutability, so Tokiwa-Iro is a color that praises green with a wish for longevity and prosperity. It is said this color was appreciated, especially in the Edo period, as a good-luck color. The pine tree design gives us an elegant and noble impression; it might be another reason that people love this motif.
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).
There is a geometric design of wave pattern; the Seigaiha Monyou (青海波文様). According to a theory, this design symbolizes the benefits of the vast sea. This infinite wave pattern is an auspicious pattern. People used it, wishing eternal happiness and peaceful lives for the future.
Also, a part of the surface is decorated with Nanako-Ji (魚子地). The groundwork was hit by Nanakoji-Tagane (chisel for metalworking), so small dents cover the background. Each little dot looks like a fish egg; therefore, its name “Nanako” is written as children of fish in Kanji (a kind of Japanese character).
Tsuka and Menuki：Tsuka is the handle of the Japanese sword and Menuki is its decoration.
The motif of this menuki is Smurai on horseback.
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.
The motif of the Tsuba is butterflies and waves. A larva becomes a chrysalis, and it grows up to a butterfly. As this insect changes its looks, it symbolizes reborn; therefore, Samurai loved the butterfly pattern. Also, as butterflies make a couple on good terms, this motif represents happy marriage.
Kozuka：Kozuka is a small knife stored in Kozuka Hitsu(groove of the sheath of the Japanese sword).
Kougai：Kougai is the equipment for Samurai to arrange or fix his hair style.
Saya：Saya is the scabbard for the Japanese sword.
This Saya is covered with black lacquer. Due to its high waterproof effect, lacquer has been used since ancient times in Asia. The blade of a Japanese sword is made of iron, and moisture is the greatest enemy of iron. For the purpose of carrying the blade without degrading it, people devised a method of coating the scabbard with lacquer. To prevent not only moisture but also rain and snow from penetrating the inside of the scabbard, it was necessary to apply multiple layers of lacquer. The Nushi (塗師, lacquerers) was born precisely because advanced techniques were required to handle the complicated processes.
Authentication Paper：NBTHK Tokubetsu Hozon Certificate for the blade (No. 1023024 )
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 August 23rd in the 6th year of Reiwa (2024). 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.
