This is a c. 1955-1959 Yotsubishi fountain pen decorated with a Kawari-nuri technique sakura (cherry) bark pattern. The free form artwork recreates the pattern using contrasting yellow/gold elements in the red urushi lacquer base. It’s 5 1/4 inches long with gold filled trim and uses a squeeze type filler, possibly aerometric (which would require a feed tube), that dates the pen to the 1950s, following the lead of the filler design in the Parker 51 Aerometric. The gold nib is stamped WARRANTED over 14K over the JIS mark over 3253 over 4.

This is a Yotubishi black hard rubber fountain pen with a design carved and then lacquered resembling a shakuhachi 尺八 (Japanese bamboo flute), c. 1955-1957. The Ishi-Shoten Yotsubishi pen company consistently marked their pens on the clip top or cap band with the company’s four diamond logo. In some cases, the clip may be stamped YOTUBISI. Those maker's marks are absent from this example. A visually identical pen is shown on a page from the 1957 Ishi-Shoten Catalog, appearing on page 113 of Fountain Pens of Japan. The caption says “Chikoku (bamboo look), lacquered hard rubber,” though a literal meaning for chikoku 遅刻 may be slow carving.
