What Is Shinshinto? 新々刀 — The New-New Sword Revival
Shinshinto (新々刀), the "New-New Sword" period, is the era of Japanese swordmaking running roughly from 1781 to 1876, a deliberate revival movement in which smiths turned away from the ornate decline of late Shinto work and consciously recreated the great styles of the Koto masters. Led by the reformer Suishinshi Masahide, shinshinto smiths studied and revived Kamakura and Nanbokucho techniques, producing robust, ambitious blades that rank among the finest of the later periods.
For a collector, shinshinto occupies a rewarding middle ground: these swords are old enough to be genuine antiques with real history, yet young enough that many survive in superb condition with crisp signatures — making them among the most accessible high-quality nihonto to acquire and study.
When shinshinto begins and ends
Nihonto are classified by period, and shinshinto sits between the Shinto and Gendaito eras:
- Koto (古刀) — "old swords," up to circa 1596, the classical age of the gokaden.
- Shinto (新刀) — "new swords," circa 1596 to 1781, the Edo-period commercial flowering.
- Shinshinto (新々刀) — "new-new swords," circa 1781 to 1876, the revival.
- Gendaito (現代刀) — "modern swords," from 1876 onward.
The end date, 1876, is fixed by history: the Haitorei edict of the new Meiji government banned the wearing of swords in public, abruptly ending the samurai era and, with it, the shinshinto age.
Why shinshinto happened: the revival movement
By the late 18th century, sword fashion had drifted toward showy, over-decorated hamon and a decline in fundamental forging quality. Suishinshi Masahide (水心子正秀) diagnosed this as decadence and launched a back-to-basics reform: study the old masters, recover lost forging and quenching methods, and value strength and honesty over decoration. He called the flashy toranba-style hamon a mistake and preached the return to Koto virtue.
The result was a self-conscious revivalist school. Shinshinto smiths made deliberate copies (utsushi) of Bizen, Soshu, and Yamashiro classics, often executed with formidable technical skill — and because they worked from good imported steel and mature technique, the best shinshinto blades are powerful, healthy, and large.
The great shinshinto smiths
- Suishinshi Masahide (水心子正秀) — the movement's founder and teacher, whose writings reshaped the craft; revered as the father of shinshinto.
- Taikei Naotane (大慶直胤) — Masahide's greatest pupil, a virtuoso who could convincingly reproduce almost any Koto style, especially Bizen choji and Soshu.
- Minamoto Kiyomaro (源清麿) — the "Yotsuya Masamune," a tragic genius whose bold, powerful Soshu-style blades are the most sought-after and valuable of the entire period.
- Koyama Munetsugu and Chounsai Tsunatoshi — masters of vivid revival-Bizen choji hamon.
What shinshinto means for a buyer
Shinshinto blades are often magnificent to look at: wide, thick, and full of activity, made when smiths deliberately showed off technique. Because they are relatively recent, condition is frequently excellent, signatures are usually intact, and documentation is easier to establish. A signed, papered Naotane or a fine revival-Bizen blade offers Koto-level artistry at a more attainable entry point than a genuine Kamakura masterpiece.
The exception is Kiyomaro, whose scarcity and reputation push prices to the very top of the market — and whose fame makes his signature one of the most frequently faked in nihonto, so buy Kiyomaro-attributed work only with impeccable papers. As always, verify the period against the sugata and confirm the mei; an era converter helps place a dated signature precisely.
Frequently asked questions
What does shinshinto mean?
Shinshinto (新々刀) means "new-new swords" and refers to Japanese blades made roughly between 1781 and 1876. It was a deliberate revival period in which smiths recreated the classical Koto styles after the perceived decline of late Shinto work.
What is the difference between shinto and shinshinto?
Shinto ("new swords," c. 1596-1781) reflects Edo-period commercial taste and often ornate, distinctive hamon. Shinshinto ("new-new swords," c. 1781-1876) was a conscious revival that rejected that trend and returned to the robust, classical methods of the older Koto masters.
Who founded the shinshinto revival?
Suishinshi Masahide (水心子正秀) launched the shinshinto movement in the late 18th century, teaching a return to Koto-era forging virtue over decorative excess. His pupils, including Taikei Naotane, carried the revival to its height.
Are shinshinto swords good to collect?
Yes. Shinshinto blades are genuine antiques that often survive in excellent condition with intact signatures, offering Koto-level artistry at a more accessible price. Work by Kiyomaro is the notable high-value exception and is frequently faked, so it demands strong papers.
