The Gravitas of Shinsa, reflections on my first year in Nihonto

[treverorum]

Hi everyone,

I wanted to share a reflection after completing my first full year in this incredible field.

 

Over the years, I have been an avid collector of many things, ranging from precisely catalogued historical multiples and rare editions (such as coins and books) to the more subjective realm of fine art and contemporary pieces. I was used to the world of almanacs and the subjective opinions of art critics. But after one year of being entangled in the world of Nihonto, I’ve realized this is something else entirely.

 

What fascinates me most, and what has truly trapped me in this hobby, is the unique intersection of high art and the rigorous Japanese legal framework. Unlike any other field of art, we are dealing with a mandatory government registration system that defines a sword’s existence as a legal art object. But the real magic happens when this legal status meets the expert judgment of the Shinsa. In the world of fine art, you often chase a signature. Here, we look for a soul. When a group of experts gazes into the jihada and hamon, they aren't just checking a box; they are identifying the hand of a master who lived centuries ago. They are giving an anonymous piece of steel its name and its history back.

 

This strict, tiered hierarchy, from Hozon to the Juyo and Tokubetsu Juyo levels, feels to me more than just a ranking, it is a path of merit that honors the spirit of the smith. To hold an object that has been scrutinized by such a body, and to find it recorded in a work like the Juyo Token Nado Zufu, creates a level of gravitas I have never encountered in any other hobby. It transforms a beautiful blade into a verified vessel of both history and spirit.

 

Even after a year of navigating the challenges of the market, encountering gimei, fake documentation, and the complexities of mumei attributions, my respect for this system has only grown. It’s not just about owning art; it’s about the certainty that comes when art, law, and a thousand years of tradition meet to protect the soul of the Japanese sword.

 

I’m curious if others here, especially those coming from a background in fine art, had a similar realization? That the unique Japanese system of judging and registration is actually what sets this apart from every other form of collecting?

Many Asian countries have zero weapon ownership tolerance and therefore have goveenment certified “experts" providing expertise and assigning status such as indigenous art, cultural property, cultural treasure etc.. Juyo and TJ are natural analogues of government rankings, which are also common in Asia. To the point that S ranked item has to have at least that many hotels next to museum housing it etc etc. Japanese system is probably not the most formal in the region by many metrics.

Agreed, the Shinsa is unique in the world as a government sanctioned event that authenticates an entire asset class and accessories. To have experts that have to complete decades of study to recognise the artist is just incredible - I am unaware of any other area like it - be it art, science or any other activity. That there are some many smiths and traditions it is incredible how much knowledge you need to have to become a recognised expert and even then when you speak to a master authenticator with 40 years experience they will still say they are learning. It is remarkable. Almost super human.

 

The closest we have to this in the west is the individual authentication boards or committees for an artist. But even then these groups focus on one or maybe a few artists not an entire asset class.

 

As we move forward I would love to see some of the western art influence this extraordinary eastern art. Things like having a catalogue raisonné for the big named smiths would be a massive move that would greatly improve this art form and have many advantages (aside from the fact that you will finally be able to see all the recognised works of the smith in one collective work - which in itself would be wonderful.) 

 

I hope this will happen sooner rather than later.

 

But for now like you I am completely and utterly engrossed.

 

There is no art form like Nihonto.

@Rivkin That’s a fascinating perspective. I wasn't aware that in some regions, status rankings were linked to external metrics like hotel infrastructure; that seems to bypass art appreciation in favor of state-driven tourism management. Those more formal systems are obviously derived from a history of looted heritage, resulting in a 'defensive' bureaucracy.

 

What sets Japan apart for me is the nature of the ranking itself. In Japan, the rank is a hallmark of quality that travels with the blade across the globe. In the other countries you mentioned, it is often a label that removes the object from the world.

Humm... NBTHK is not a government organization.

and they still get it wrong all the time and provide wide, gutless attributions.  one may ask "what is the value of shinsa" - I would argue that it is worth less than a Nagoya-Mono anymore.

[Rivkin]

Every established collecting community with items at high level has either individual or collective appraisals.

With top tier paintings there are institutes dedicated to specific artists or schools and you are expected to submit a painting for their consideration, unless its already well known and published. Sometimes there is an alternative when there is an individual who publishes catalogue raisonne than you send the painting to him and he writes back description and whether it will be included in the next edition.

Until 1960s museums in general offered opinions to anyone inquiring, now its considered unethical to do so because museums are trying to separate themselves from the unclean world of money and also avoid any controversies.

 

There are countries like Russia, to lesser extent China, and many others in Asia where there is a government certified expertise in regards to any "weapon" that might have cultural or historic value.

Overall estimation and valuation is approached with far lesser hesitation in Asia compared to Europe.

There is no concept of "equality" but rather you are always facing your grades, class standing, achievements being publicly catalogued and displayed. People are very forward about perceiving themselves as X seat in their profession.

If someone says "I am 45th grandmaster in chess" he is from Asia. Other people sometimes say "I am top three" or "top five", but everything below is vague and flexible.

In Asia assigning levels to any work, including artwork, is very natural by comparison, and constantly submitting pieces for appraisal is a norm. If you a "writer" it means you got 1st prize in at least two of first or second tier competitions. Otherwise you are just a person who writes as a hobby.

I think you will see, like all things, words matter. It was never said it was a government organisation it was said to be "government sanctioned". Even the link you provided advises the same. Hope this clarifies.

 

Have a good day.

Very interesting topic, nicely explained. Do the ‘official appraisers’ have to undertake blind identification of already authenticated swords as part of their training and in ‘continuing professional development’ as medical/science people etc are required? 

 

A few years ago, a group of influential wine connoisseurs were asked, under strict conditions, to taste the previous year’s top ten wines including the bronze, silver and gold medal winners and place them in order. Their efforts were no better than random rankings and they especially couldn’t identify the gold medal winner 😆 No doubt that was due to particularly high solar activity or a ‘skeptic present in the room’ during the tasting! 

[ROKUJURO]

Not surprizing. How do you quantify "taste" or "liking"?

With swords (or any other works of art), it is not much better. There are many facts and variables to learn and to consider when making a statement.

While I haven't seen this "study" you're referencing, I'm not sure your conclusions follow or derision makes any sense, at least from your description of it. Do you have a link or source setting out the methodology?

 

More generally, any list of top wines is one person or panel's subjective opinions, and one wouldn't expect a different person or panel to reproduce it. It's not some list with objectively gradiating features that distinguish one from the other in terms of "quality" when clearly they are all good wines. This is why people into wine read reviews and rankings lists written by multiple people and learn to understand the tastes and preferences of the reviewers and how they match up with their own. The question I would have thought more pertinent would be whether the experts (who I'll assume were sommeliers, not just connoisseurs) could identify the wines, not order them based on the results of someone else's rankings.  This isn't to say there isn't plenty of bunk in the wine world, but I'm not sure whatever it is you've identified here counts for much. 

 

Regardless, back to swords, and while I certainly can't speak to any requirements of assessors, nyusatsu kantei is very much a thing and one would imagine something they participate in regularly. It might be worth your checking out the regular kantei problems posted by the NBTHK (latest here: https://www.touken.or.jp/english/nbthk/swordjournal_December.html) and referencing some of the usual books on the process.

 For NBTHK I think they are doing great job and it does support the organization financially. My only worry is the large amount of items that they do process through every year. I think the organization realized the problem and they did put a item number limit to Hozon & Tokubetsu Hozon shinsa quite recently, and it is now limited to 1,600 swords per session. Now as they do 4 sessions per year that would be 6,400 swords, then you add the Jūyō submitted swords and it would be 7,000+ swords. 

 

Here are NBTHK numbers I digged from magazines 5+ years ago (I had actually forgotten I did this ): 

 

NTHK (including both branches) is much smaller organization, however I do know for their international shinsa they have the minimum item requirements for shinsa team to attend. I know NTHK is not preferred by market but I still value their opinion highly too.

 

As the item submission numbers are quite large for shinsa sessions I am left wondering how many minutes each blade gets? Now the time invested will of course vary from item to item. I do understand that experts can see fine details in swords very fast and in few minutes can tell interesting things about the item, I have seen this in European NBTHK meetings for example.
