Small, green-bodied component with color stripes marked as a capacitor

On the PCB of a Casio printing calculator, I found these kinds of capacitors with an unusual appearance. They're sized like an 1/8-th watt resistor and even have color stripes, but are indeed specified as capacitors nonetheless.

A service manual for a related model (DR-120XA) mentions the type of some components as "semiconductive capacitor" [sic], which might be related to the kind I see here.

Since I couldn't find an illustration of the component with such a name, I'd like to clarify what the part shown actually is, how it differs from the common ceramic capacitors and why is it so rare.

As @Nick says in a comment, they are axial-lead ceramic capacitors and are (or were) made in similar dielectric types to common MLCC SMT capacitors.

Here is a datasheet from one supplier (Taiyo Yuden) who used the color band marking method.

They were briefly very common in Japanese-designed electronics (maybe 30 years ago), then SMT mostly pushed them out. The light green and a kind of pinky-brown were typical body colours from different manufacturers.
