When a Dragon Lives in Steel — Tokubetsu Hozon

Izumi no Kami Senjuin Morikuni

NBTHK Tokubetsu Hozon (Special Preservation) — Certified 1990

Blade Length: 71.3 cm

Curvature: 1.34 cm

Smith Rating: Jō-saku (Superior Work)

A Smith of Established Rank

This katana comes from Morikuni of the Senjuin tradition, a swordsmith recognized with the ranking of Jō-saku.

In the world of Japanese sword appraisal, Jō-saku is not given lightly.

It does not mean a smith happened to produce one excellent blade.

Rather, it indicates a craftsman whose work has been historically recognized as consistently high in quality.

Morikuni holds a firm place among the Shintō period swordsmiths of Edo—a maker whose reputation is grounded in stability, not accident.

The Prestigious Senjuin Lineage

The name Senjuin carries deep historical weight.

The Senjuin school traces its origins back to the ancient Yamato tradition, closely connected to the cultural and religious sphere of Tōdai-ji Temple in Nara.

Since the Kamakura period, swords of this lineage have been known for works that carry a strong spiritual character.

Morikuni, inheriting this name in Edo, was not merely a town smith.

He stood at a point where an ancient lineage met the central current of Edo-period swordmaking.

Certified as Tokubetsu Hozon

This particular blade is signed by Morikuni and designated Tokubetsu Hozon (Special Preservation) by the NBTHK.

Even more noteworthy is the year of certification: 1990.

During the early Heisei period, the standards for Tokubetsu Hozon were widely considered stricter than they are today.

Both the quality of the work and the condition of preservation had to meet a very high level to pass.

In other words, at the time of its examination, this blade was clearly judged to be one level above the ordinary.

A Perfectly Balanced Sugata

The blade’s proportions are ideal for appreciation.

• Blade Length: 71.3 cm
  

• Curvature: 1.34 cm
  
  

The curvature is neither exaggerated nor shallow.

The lines flow naturally, and the axis of the blade remains straight and stable.

Despite its long and impressive length, the overall shape never loses balance—

a sign of a blade built on strong structural foundations.

The jihada (surface steel) is refined.

The hamon (temper line) is controlled and dignified.

There is no unnecessary flamboyance.

Instead, the sword expresses its quality quietly and confidently.

The Carvings That Make This Blade Extraordinary

What elevates this sword from remarkable to truly special is its horimono (engraving composition).

On the front of the blade appear three sacred figures:

• Monju Bosatsu (Manjushri) riding a lion
  

• Bishamonten holding a treasure pagoda
  

• Dainichi Nyorai, the cosmic Buddha
  
  

Each represents a powerful concept.

• Monju — wisdom
  

• Bishamonten — protection and martial power
  

• Dainichi — the fundamental principle of the universe
  
  

Placed together with Dainichi at the center, the arrangement reflects a clearly designed esoteric Buddhist cosmology—wisdom and protection supporting the universal truth.

On the reverse side:

Kurikara Dragon

The Kurikara dragon represents the sword of Fudō Myōō, symbolizing the power to cut through worldly delusion.

If the three figures on the front represent principle and order,

the Kurikara dragon on the reverse represents the force that executes it.

Philosophy and action.

Reason and power.

Both sides of this concept are unified within a single blade.

Harmony in Complexity

In Japanese swords, more carvings do not automatically mean higher value.

In fact, the more themes introduced, the harder it becomes to maintain harmony.

This blade contains an unusually dense religious program—

three sacred figures on one side and Kurikara on the other.

Yet the overall balance of the sword remains uncompromised,

and it still achieved Tokubetsu Hozon certification.

This is where the true level of craftsmanship reveals itself.

A Rare Combination of Qualities

This sword brings together an exceptional set of conditions:

• A signed blade by a Jō-saku ranked swordsmith

• Strict Tokubetsu Hozon certification from the early Heisei era

• A unified esoteric Buddhist horimono composition

• A long blade with beautifully balanced proportions

• Excellent preservation with no current flaws

Blades where all of these elements align at once are not something the market constantly offers.

If even one of these conditions were missing, the persuasive power of the piece would be far weaker.

A Custom Koshirae by Ryūichi

To complete this sword, a custom koshirae by Ryūichi will be commissioned.

Not a standard mounting.

This will be an exterior designed specifically to match the spirit and dignity of this blade.

Its purpose is to elevate the sword into a complete and unique work, where history, meaning, and form come together.

More Than a Purchase

This is not simply buying a sword.

It is acquiring a blade where:

• historical lineage
  

• religious symbolism
  

• recognized craftsmanship
  

• strict authentication
  

• and a future custom mounting
  
  

all converge into one piece.

One Sword for a Lifetime

Some swords are beautiful.

Some swords are historically important.

Very few gather all the reasons necessary to call them a once-in-a-lifetime blade.

This one does.
