NihontoWatchNihontoWatchAccording to its certificate, this Tsuba’s maker is Gassan (月山), or called Matsuo Gassan (松尾月山) and Karoku (嘉六), who was born in the 12th year of the Bunka era (1815) and active in the late Edo period in Yamashiro province (today’s Kyoto prefecture). At the age of 12, he became an apprentice of Kawarabayashi Hideoki (川原林秀興), a prominent figure of the renowned Otsuki school (名流大月派) in Kyoto, and Gassan achieved great success not only in his excellent carving technique, but also in his design composition. This Tsuba is made of highly forged and densely packed iron ground. His authentic works are said to be rare and valuable. About the design, waves (波, Nami) lapping fiercely are carved on this Tsuba and the golden wave crests are finished with the Zogan (象嵌) technique, a beautiful traditional Japanese inlay craft. 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). We hope you will appreciate this work. Authentication Paper This Tsuba has the certificate that was issued by the Nihon Tousougu Kenkyukai (日本刀装具研究会). This organization is different from NBTHK, known as Nihon Bijutsu Touken Hozon Kyokai (the Society for the Preservation of the Japan Art Sword), nor NTHK, known as NPO Nihon Touken Hozon Kai. They authenticated the Tsuba on May 10th in the 6th year of Reiwa (2024).

Matsuo Gassan was a late-Edo Kyoto metalwork artist of the Otsuki school. The records give his identity in full: his real name was Matsuo Karoku, he was born in Kyoto in Bunka 12 (1815) and died in Meiji 8 (1875) aged sixty-one, and he signed under the studio-go Kongosai and Tososhitei. They make him a pupil of Kawarabayashi Hideoki of the Otsuki school (the same teacher as Sasayama Tokuoki), and one record names him a fine hand who honed his skill alongside his fellow Hideoki pupils Tokuoki and Tenkodo Hidekuni. His ground and hand are the Otsuki house manner: shakudo, brass, iron and shibuichi grounds worked in high relief and colour inlay, with katakiri-bori where the design calls for it, and the records read the Otsuki-school quality plainly in his work. The records single out two things as personal to him: that he produced many tsuba (rather than the small okite-mono of the Goto house), and that he excelled at figure-pictures, beginning with warrior-pictures (musha-e), and worked widely in birds, animals and the lion. His celebrated piece is a Koromogawa-yakata tsuba depicting a scene of the Former and Later Nine Years battles, called one of his representative works. One whole koshirae here is unified by Otsu-e folk-painting subjects, each charm-bearing. With only four pieces, all Important (Juyo), this is a very thin corpus, and the genuine separators from the broader machibori field are scope-tight and low-n. This profile reads his identity, biography and signature chronology from the catalog records only. (Note: the art-name Gassan is also famous as a swordsmith line; this Gassan is a soft-metal fittings maker of the Kyoto Otsuki school, unrelated to that smith lineage.)

The Otsuki school is a distinguished lineage of Kyoto kinko (metalworkers) whose production spans from the mid-Edo period through the Bakumatsu era, consistently identified by the NBTHK as one of the most eminent metalworking lineages of the capital. " The school also acknowledged its debt to earlier Kyoto masters, with the NBTHK detecting in Mitsuoki's modeling the influence of Umetada Myoju and in his pictorial conception the influence of Kaneie. The collective technical vocabulary of the Otsuki school centers on takabori iroe (high-relief carving with polychrome metalwork), deployed with a fundamentally pictorial intelligence that distinguishes it from most other metalworking lineages. Across multiple generations, Otsuki artists worked in katakiribori (single-chisel engraving), hira-zogan (flat inlay), sukidashi-bori (relief modeling from the plate), and fine kebori (hairline engraving), often combining several techniques within a single composition. A defining characteristic is the school's command of varied ground materials -- iron, shakudo, shibuichi, oborogin, brass, and even solid gold -- finished as migaki-ji (polished), nanako-ji (fish-roe stipple), arashi-ji, or ishime-ji, each selected to serve the pictorial demands of the subject. " In subsequent generations, Atsuoki demonstrated daring compositional arrangements while maintaining an unmistakably Kyoto refinement, and Hidekuni achieved effects of "keen sharpness and driving momentum" through masterful deployment of irogane alloys.
Across the school's output, compositions characteristically make effective use of generous open space to achieve atmospheric depth, narrative pull, and a lyric quality that the NBTHK repeatedly identifies as distinctively Otsuki. The Otsuki school's legacy rests on its fusion of painter's sensibility with metalworker's discipline, producing works of a character at once bold and subtly graceful. " Atsuoki's commissions for both the Tokugawa shogunate and the imperial household -- including fittings for the wearing sword of the fourteenth shogun Tokugawa Iemochi and for Emperor Komei -- attest to the esteem in which the school was held at the highest levels of patronage. Hidekuni's later works exhibit "an airy and unconventional spirit" emblematic of Mitsuoki's own late manner, confirming that the school's aesthetic evolution was one of deepening refinement rather than mere technical inheritance. The NBTHK consistently positions the Otsuki school among Kyoto's most eminent metalworking traditions, and its members' works -- from Motohiro's ambitious narrative programs treating the Fifty-three Stations of the Tokaido to Kaizan Oki's compositions of "elevated tone and dignity" -- constitute an essential chapter in the history of late Edo-period chokinshi artistry.
