Hizen swords were a domain enterprise: the Nabeshima sent Tadayoshi to study under Umetada Myōju around 1596, then built a licensed school around him. Nine generations carried its famously consistent konuka-hada work into the Meiji era.
Summary This blade is attributed to Den Bushū Shitahara Masahiro (伝 武州下原正廣) and is dated to the Tenshō era of the Azuchi-Momoyama period (1573–1592), according to the NTHK certificate. Bushū Shitahara refers to the area where this blade was forged, located in present-day Hachioji, Tokyo. According to Japanese sword references, swordsmiths first settled in Shitahara around 1588 (Tenshō 16), shortly after the construction of Hachioji Castle. Today, Hachioji Castle is designated as a National Historic Site and is recognized as one of Japan’s 100 Famous Castles. Masahiro belonged to the Bushū Shitahara School, which flourished from the late Muromachi period through the late Edo period (approximately the late 16th to the late 19th century). The school is traditionally believed to have been founded by Yamamoto Norishige. The Shitahara swordsmiths originally served the Later Hōjō clan, one of the most powerful samurai families in the Kantō region during the late Muromachi and Azuchi-Momoyama periods. Their swords were valued for their practicality and durability, reflecting the needs of warriors in an era of frequent warfare. After the Toyotomi clan destroyed the Hojo clan in the Azuchi Momoyama period, Shitahara started to serve the Tokugawa clan as Okakae Kaji, swordsmiths exclusively working for a specific feudal family. Most of the Shitahara swordsmith’s real sir name was Yamamoto. They especially flourished during the late Muromachi period-early Edo period. They kept forging for the Tokugawa clan until the end of the Edo period. As you can see, Masahiro’s active period was from the Azuchi Momoyama-early Edo period. That signifies that he forged blades during the heyday of this school. And you can see beautiful craftsmanship from this Wakizashi. *Please keep in mind that there are a few Kitae Kizu on this blade. Fuchi-Kashira This Fuchi-Kashira features bellflowers (桔梗, Kikyō) and dragonflies (蜻蛉, Tonbo). The graceful bellflowers swaying in the autumn breeze, accompanied by dragonflies in flight, create a refined seasonal scene. This composition was also famously depicted by the renowned Edo-period artist Katsushika Hokusai, reflecting its popularity in Japanese art. In Japan, the dragonfly has long been regarded as a symbol of victory and courage. Because it is believed to fly only forward and never backward, it became known as the “victory insect” (勝ち虫, kachimushi) and was especially favored by Samurai warriors as a symbol of determination and success in battle. Tsuka and Menuki The motif of this menuki is believed to depict an autumn grasses (秋草, Akikusa). In Japanese art, autumn grasses are a traditional seasonal motif that represents the beauty and transience of nature. Tsuba and Habaki This Tsuba appears to depict dandelions (蒲公英, Tanpopo). In Japan, dandelions have long been appreciated for their bright yellow flowers and familiar appearance. Although small and delicate in appearance, they are remarkably resilient. Even if the stem is cut, the plant can grow again as long as its roots remain intact. This strong vitality and ability to regenerate may have symbolized perseverance and resilience, qualities highly admired by Samurai warriors. For this reason, the dandelion may have been chosen as a motif representing strength in the face of adversity. Saya We estimate the surface of this Saya is decorated with the Ishime-Ji (石目地). Its base was hit by Tagane (鏨, chisel for metalworking), and it makes a rough surface that seems stone. Authentication Paper NTHK, also known as NPO Nihon Touken Hozon Kai, is the oldest organization for sword authentication of Japanese swords in modern times. It was established in 1910 during the post-Samurai era. They authenticated the blade on June 21st in the 8th year of Reiwa (2026). Registration Number It is called Jyu Hou Touken Rui Torokusho (銃砲刀剣類登録証).

The Hizen school began with a single domain commission. In Keicho 1 (1596) the Nabeshima of Hizen ordered Hashimoto Shinzaemon, the smith who would sign Tadayoshi, up to Kyoto with the carver Munenaga; there he entered the gate of Umetada Myoju and studied forging while Munenaga learned the chisel. The two returned to the province in Keicho 3 (1598), and Tadayoshi settled in the castle town below Saga, where under the domain's patronage the line grew into the dominant sword-making house of Kyushu. His own work runs from Keicho 5 (1600) to his death in Kan'ei 9 (1632); in Genna 10 (1624) he received the court title Musashi Daijo, changed his name to Tadahiro, and shifted his clan name from Minamoto to Fujiwara, so that the late Musashi Daijo blades are the founder under a second name. From him the house became a true generational institution: his son the second-generation Omi Daijo Tadahiro carried it forward as its most prolific hand, the third-generation Mutsu no Kami Tadayoshi returned its highest finish, and a Tosa no Kami branch took the founder's signature when he set it aside. Around this main line grew a circle of disciples and collateral hands, the waki-Hizen or Soba-Hizen smiths, several of them, like Yoshiie and Hironori, working as daisaku substitute makers whose own signed pieces are therefore scarce. The school's signature is its steel. Over a ko-itame forged so tightly it shows no slackness, fine ji-nie gathers in minute particles until the surface takes on the rice-bran konuka-hada (also written komenuka-hada) that no other school produces, fine chikei entering throughout and the ji notably clear and bright.
The orthodox temper laid upon it is a chu-suguha or hiro-suguha, sometimes tinged with a shallow notare and ko-gunome, the nioiguchi deep with finely clustered ko-nie and tightened to a bright clarity, the boshi running straight to a quiet ko-maru. The founder aimed this suguha toward the Rai school yet departed from it, his nioiguchi tighter and his forging carrying more vigor; the third generation refined it to what the published sources call the strongest and most precise hand of the first three generations. Against that calm register the house also worked a showier one, the Hizen choji-midare mixing gunome, long ashi, kinsuji and sunagashi, a manner the published sources already find more often in the founder's late Musashi Daijo work than in his Tadayoshi years, and one the second generation made his own. The branches pushed further from the suguha standard: Tadakuni of the Ogi domain ran sunagashi more conspicuously than any other Hizen hand and reached toward old Ichimonji in his o-choji; Masahiro and Yukihiro favored a flamboyant long-ashi choji over the calm main line; and the Iyo no Jo Munetsugu line worked apart in the Soshu-den, building a midareba on notare with a pointed togariba and a jihada that tends to stand and tone slightly blackish. A collector seeks Hizen-to first for that steel, and reads it the same way the appraiser does: a bright suguha lying over a clear, tight konuka-hada identifies the school before the signature is consulted, and the quiet ko-maru boshi on the ura-signed tang confirms the main-line practice. Generation and branch are then told within that frame, the third generation's powerful sugata recalling not his father but his grandfather, the waki-Hizen hands set apart by their irregular temper, their sujikai file marks and a sashi-ura signature, the Munetsugu line by its Soshu togari. The main line, made in real numbers across so long a span, reaches the market more readily than any Kamakura master, so a papered example is within reach of a patient collector, while the founder's own work and the finest konuka-suguha of the third generation come to open hands only from time to time. Provenance runs back through the house the school served, blades recorded to Nabeshima Katsushige and Nabeshima Naomoto and passing onward to the Owari Tokugawa, the Satake and the Imperial families; documentary inscriptions sharpen the picture further, a Myoju soemei attesting the founder's discipleship, Umetada carving adding flowers to brocade on his late blades, and the gold-inlaid cutting tests of Yamano Kanjuro and Yamano Ka'emon, rare on Hizen work, naming the edge as well as the hand.

Hizen: a domain enterprise

The NTHK’s principal certificate, issued for a blade of considerable quality. It confirms a genuine signature, or, for an unsigned (mumei) work, records the judges’ attribution to a smith or school. The paper carries a detailed worksheet with a numerical point score.
The NTHK (Nihon Tōken Hozon Kai, the Society for the Preservation of the Japanese Sword) is the oldest of Japan’s sword-appraisal bodies, founded in 1910, decades before the NBTHK. After the death of its long-serving head it divided into two successor societies, the NTHK and the NTHK-NPO, both of which continue to hold shinsa. NTHK certificates are known for a detailed worksheet that records a numerical point score alongside the judges’ written opinion, and the society is especially respected for its attribution of unsigned (mumei) work.
