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.

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.
