What Is Notare? 湾れ — The Gentle Wave Hamon Explained
Notare (湾れ) is a gently undulating hamon — a temper line of broad, shallow, wave-like curves that roll along the edge like a slow ocean swell, without the sharp peaks of gunome or the clove-heads of choji. It sits between the perfect straightness of suguha and the busy irregularity of the midare patterns, giving a blade a calm, flowing, dignified character. Notare is closely tied to the Sōshū tradition and became one of the most influential hamon in Japanese sword history.
For a collector, notare is a pattern that rewards a settled eye. Its beauty is not in drama but in rhythm — the evenness of the waves, the brightness of the nioiguchi through each curve, and the activities that gather in the valleys and crests. A well-formed notare from a strong school is among the most elegant sights on a Japanese blade.
How notare is formed and its variations
Notare is created, like all hamon (剛文), by shaping the clay coat before the quench — here in long, gentle, wave-like sweeps so the hardened martensite band rises and falls in broad curves. The waves are shallow and open, unlike the tight, regular bumps of gunome (互の目). Notare rarely appears completely alone; it is most often the underlying rhythm on which other elements are laid:
- Ō-notare (大湾れ) — large notare, wide sweeping waves, associated with the grand hamon of the Sōshū master Sadamune and later Shizu smiths.
- Notare-midare — a notare base mixed with irregular activity for a livelier line.
- Gunome-notare — gunome peaks riding on a notare wave, a common and highly characteristic combination.
- Ko-notare (小湾れ) — small, gentle undulations, close to a wavy suguha.
Because notare is so often a foundation for mixed patterns, appraisers pay attention to how deep and how regular the waves are, and to what rides on top of them — the combination is frequently more diagnostic of a school than the notare itself.
Which schools and smiths favored notare
Notare is a signature of the Sōshū (Sagami) tradition and the schools that grew from it. It is inseparable from the story of the tradition's greatest names:
- Sōshū Sadamune — a foremost student of Masamune, famous for broad, flowing ō-notare in brilliant nie.
- Shizu Kaneuji — carried the Sōshū style into Mino province, working notare-midare with strong nie activity.
- Sue-Sōshū and later followers — sustained notare through the late koto (古刀) period.
- Shinto-era masters (Horikawa Kunihiro, Shinkai) — revived and refined notare-based hamon in the 1600s.
The combination of a flowing notare with abundant nie (沣), kinsuji, and sunagashi is one of the most recognizable Sōshū calling cards, which is why reading the wave against its activities is central to placing such a blade.
Reading notare for kantei
In kantei (鑧定, appraisal), notare directs attention to the shape and quality of the waves and to what sits within them. An appraiser judges whether the undulations are broad and calm (pointing toward Sōshū and its heirs) or shallow and regular, whether the nioiguchi stays bright and unbroken through every crest and trough, and how the line resolves in the boshi (帽子) at the tip. Rich nie, kinsuji, and sunagashi flowing along a notare strongly suggest the Sōshū lineage; a plain, activity-poor notare suggests a lesser or provincial hand.
Notare's smooth curves can also flatter a fake at a glance, but the tell is the same as for any hamon: an etched imitation has no living nioiguchi, no nie glittering in the waves, and no coherent boshi. On a genuine notare the temper line breathes with crystalline activity through every swell; on a fake it is a flat, painted-looking ripple.
Frequently asked questions
What is a notare hamon?
Notare (湾れ) is a gently undulating temper line of broad, shallow, wave-like curves running along the edge, like a slow ocean swell. It is calmer than the sharp peaks of gunome or the clove-heads of choji, and sits between the straightness of suguha and the busy irregular midare patterns. Notare is a signature of the Sōshū tradition.
What is the difference between notare and gunome?
Notare is a broad, gentle, flowing wave, while gunome is a series of tight, regular, rounded bumps like a row of half-circles. Notare's undulations are wide and open; gunome's are small and evenly repeated. The two are often combined as gunome-notare, with gunome peaks riding on a notare base.
Which swordsmiths are known for notare?
Notare is a hallmark of the Sōshū tradition, above all Sadamune, a leading student of Masamune, famous for broad ō-notare in brilliant nie. Shizu Kaneuji carried the style into Mino, and shinto-era masters such as Horikawa Kunihiro and Shinkai later revived notare-based hamon.
Is notare a sign of a good sword?
A well-made notare with even waves, a bright unbroken nioiguchi, and rich activities such as nie and kinsuji is a mark of a skilled smith and often a strong school. Quality lies in the evenness of the rhythm and the life within the waves, not in the wave shape alone. A plain, activity-poor notare, or a flat etched imitation, points to a lesser or fake blade.
