Pocket Yotsubishi

Yet another pocket pen?

Pocket pens were not necessarily inexpensive pens despite its reduce size. In fact, as we have seen, these pens sported some unusual and exotic nibs, like those made of high purity gold in the early 1970s.

Ishi Shoten (or Ishi & Company, or Ishii Seisakusho, or Ishi Shoten Yotsubishi) was founded in 1925 by Yoshinosuke Ishii. From very early on, this company aimed at the market of maki-e and urushi-e decorated pens. After the War, this company made some of the most delicate decorated pens made in Japan. Ishi Shoten pens are usually labeled with the brand Yotsubishi (Yotubishi in an alternative transliteration).

The Ishi Shoten pen I am showing today is a pocket pen decorated with the urushi-e technique of “kanshitsu-ishime”. This is no ordinary pocket pen. As is often the case on maki-e and urushi-e pens, the decoration becomes its primary argument.

As a pen, this is a typical pocket pen. However, the decoration –the think layer of urushi— keeps it from posting fully; that is, with the cap reaching the central ring (this problem is not shown on the pictures).

A Yotsubishi pocket pen.

The dimensions are as follows:
Length closed: 119 mm
Length open: 101 mm
Length posted: 148 mm
Diameter: 13 mm
Weight: 12.3 g

The pen, in the basic disassembled state. An unusual feature of this pen is that the bottom end of the section, together with the nib and the feed, can be unscrewed from the rest. This can be useful for a thorough cleaning of the pen.

This pen uses Platinum cartridges.

The nib is made of 18 K gold and it is engraved with the four-diamond logo of Yotsubishi. This style of nib was present in other pens of the brand in the early 1960s. However, the first pocket pens, made by Sailor, were marketed in 1963.

The engraving on the nib simply says "18 K" together with the company logo on both sides.

Yotsubishi pens are hard to find and and very valued by the connoisseur. And expensive.


My thanks to Mr. Furuya.
