Japanese Eyedropper Today (I)

The so-called Japanese eyedropper system –inki-dome shiki (インキ止め式) in Japanese— was in fact invented by Onoto in the beginning of the 20th century. Those Onoto reached Japan imported by Maruzen and the system –an eyedropper with a shut-off valve— clicked among the locals. The final result was that this system was copied and reproduced by most Japanese pen makers along its history up to today.

The inki-dome, however, fell out of favor by the late 1950s when Platinum introduced the ink cartridge and most other makers followed the example. Only minor makers –I am thinking of Sakai Eisuke's operations— kept the system alive till the 1980s.

A Sakai Eisuke's pen made in collaboration with Kabutogi Ginjiro (::1::). Possibly from the 1960s.

In 1985, Pilot commissioned lathe master Sakai the creation of a prototype based on the style of the Pilot pens from the early 1930s, The result was what later became the Pilot (and Namiki) size 50 Urushi, and it implements the Japanese eyedropper system.

The Pilot Urushi in size 50--a modern Japanese eyedropper. This pen is incorrectly named by many as Namiki Emperor, but the Emperor model is decorated with maki-e techniques according to the Namiki catalog.

But who else followed? Not much.

Eboya used the system for some years (::2::, ::3::), but its production relied in the know-how of lathe master Kanesaki Noritoshi. Eboya's boss, Mr. Endo, has announced the new production of Eboya pens with this system, but there are no final dates for their release.

More recently, as of 2018, the sort-lived Iwase Seisakusho also marketed some pens with the Japanese eyedropper system. These were either old incomplete pen bodies by Ishi Shoten (owner of the brand Yotsubishi) or new pen bodies made by lathe master Momose. But Iwase Seisakusho had a very brief life and very few units of it made to the market.

From California, Danitrio makes some models with Japanese eyedropper. These are usually expensive models with urushi or maki-e decoration.

Finally, a surprising actor is the Taiwanese brand Opus 88 (Jin Gi Industrial Co.). But these Japanese eyedroppers deserve a Chronicle on their own.

Kubo's Pens

Kubo Kohei stands nowadays as the sole maker of nibs in Japan not associated with a pen maker. And this in itself is an interesting fact that deserves a separate reflection. But today I want to speak about some of the operations in which nibmeister Kubo has participated.

As of today, other that the nibs one could order directly from him, it is possible to find Kubo nibs on pens Tohma, made by Toma Kiyotaka of Pen Cluster, and on some models by Iwase Seisakusho, albeit its activity seems currently suspended.

But nibmeister Kubo has a long history in the pen industry in Japan. Two brands associated with Kubo were Nobel –or Nobel's, as he likes to call it-- and Elliott.

The Elliott company was founded by former worker of SSS Uesugi Yoshizaku around 1936 or 1937 in the Kita Ward in Tokyo. Around 1960, Kubo's uncle bought the company and Kubo Kohei started working on it. The engagement with this brand lasted until around 1980.

In parallel, at least during the late 1960s and 1970s, Kubo Kohei also worked on his own brand Nobel. For those pens, he used injected plastic for the bodies and adopted Platinum cartridges and converters as filling mechanisms, as was the common practice among small companies of the moment.

Two Nobel pens: the "Super Gold" model on top; and a pocket pen. Both were made by Kubo Kohei. They use Platinum cartridges.

So these are some of the nibs and pens made by nibmeister Kubo. However, they are not easy to find in the market.


My thanks to Mr. Kanesaki, Mr. Sugimonto and Mr. Sunami.

On Iwase Seisakusho

I have mentioned Mr. Iwase several times (::1::, ::2::) on these Chronicles—he is a pen aficionado who decided to master the craft of raden decoration.

Mr. Iwase started his training about 15 years ago. At first, he customized pens, mostly Montblanc and Pelikan, that he sold locally in Tokyo. His trade soon included some pen bodies made by lathe master Momose Yasuaki equipped with nibs by nibmeister Kubo Kohei.

In 2018, Mr. Iwase decided to become more serious and systematic on his hobby. He created the brand Iwase Seisakusho and started signing his creations. And the selling channels were Instagram and some pen shows.

The pens under the brand could be categorized in three types: customizations, a regular model, and a small number of special pens.

The customizations were made on Montablanc and Pelikan pens. Mr. Iwase applied his craft on their surface and left the operative part of the pen untouched.

A Montblanc 149 customized by Mr. Iwase.

Three customizations over Pelikan M1000.

The regular model, model N, was made over unused bodies manufactured by Ishi Shoten (owner of the brand Yotsubishi). These bodies hand to be adjusted, completed with the filling system –Japanese eyedropper-- and nib and feed sourced by nibmiester Kubo. Needless to say, the pen was decorated by Mr. Iwase with urushi and raden.

Finally, the special models –called generically Kinsei pens-- were one-of-a-kind units. The pen bodies were the work of lathe master Momose; the nibs, were, once again, the product of nibmeister Kubo.

Two examples of Kinsei pens by Iwase Seisakusho.

The problem of this operation was the very limited production that, to make matter worse, relied solely on the hands of Mr. Iwase. And as of today, July 2019, the production is stopped and the communication channels are disabled.

Iwase Seisakusho, therefore, was alive for about a year with a total production of about 30 pens.

Too few pens, and too short life.

These pens were interesting for both the decoration and the features as pens, particularly in the case of the N model and the Kinsei pens. Japanese eyedroppers with interesting nibs and ebonite feeds... And a gorgeous and well made decoration.

Interesting nib, interesting feed.

Too good to be true? Too costly? Too expensive?

Or just too much for a very small operation?


My thanks to Mr. Iwase.

The Kubo Singularity

The big three Japanese pen companies make their own nibs, and it seems very hard to get those nibs as spare parts or as third party nibs for other makers. However, there are cases of that:

Hakase uses Pilot and Sailor nibs with their own original imprint. Ohashido and Taccia do the same with Sailor nibs.

A Pilot nib labeled as Hakase.

The rest either use Pilot nibs without any modification –StyloArt Karuizawa— or use some of the traditional supplies of third party nibs: Bock for Eboya and Masahiro (although previously Masahiro implemented Pilot nibs); JoWo for Taccia (lower end pens) and Wajimaya Zen-ni.

A JoWo nib labeled as Taccia.

The newcomer Iwase Seisakusho aims at sourcing its nibs from old nibmeister Kubo Kohei for its original pens. However, this is still an uncertain operation whose continuity we can only speculate about. Not to mention that the old age of Kubo Kohei –pushing 90 years old-- might affect any plan for a long term supply of parts.

But the bottom line is that Kubo Kohei is the sole independent maker of nibs in Japan, and his production is small, slow and artisanal.

Is there room –and market— for another independent operation in Japan to supply nibs and feeds to small pen companies?

The Namiki Effect

Stylophiles are a special bunch. Driven by our anachronistic passion we often crave for certain features: gold nibs, self-filling mechanisms (as opposed to cartridges and converters), ebonite feeds, some specific materials like celluloid or ebonite,… And we demand those features for pens over certain price. Or, in other words, we might despise pens over certain price if they didn't offer some of them.

But the market might be telling us that we are mistaken. Just a quick look at today's catalogs shows how many luxury brands offer nothing but cartridge-converter pens with plastic feeds. Materials and gold nibs are less of a problem, though.

An expensive Pilot. Cartridge-converter and plastic feed.

Luxury pens of Platinum-Nakaya and Sailor are cartridge-converters. Pilot-Namiki does offer Japanese eyedroppers, but only for the biggest nib size. All the others, with nibs sizes 5, 10, and 20, are cartridge-converters despite how expensive they are.

An expensive Hakase.

Then, small makers like Eboya, Hakase, Ohashido, Stylo-Art Karuizawa, all focussed on higher-end pens only offer cartridge-converter pens. The only exception to this trend might be Masahiro and the newly-arrived Iwase Seisakusho.

Now, are these two brands –Masahiro and Iwase Seisakusho— on the right path or the success of all the other brands shows the opposite? How important are those details like ebonite feed and self-filling mechanisms in the final price –and in the final value-- of the pen?

A Masahiro pen. Expensive, but it implements an ebonite feed, a self-filling mechanism, an ebonite body, and a gold nib.

The market might be telling us that we stylophiles are still a minority in the business. Or it might only be that I am very mistaken about what we demand, and cartridge and converters and plastic feeds are perfectly all right even on very expensive pens.

Or it might be that we are very easy targets. After all, every pen has its charm, and all those cravings are not so important.

And that is the Namiki effect--expensive pens can be, in essence, very simple. Namiki has proven it through years in the market.
