Peterson identifies 3 types of wound badges. The first type is shown here, the second type is HERE, and
the third type (no picture in Peterson's book) may have been a local war wound association badge.

The Type I badges came in two classes, and each class had two versions:
sensho (wounded in battle) and
kousho (wounded in the public service). There are badges for NCOs and for officers. The badges for
officers are identical in design but they are larger.

These badges are much rarer than the later enameled badge. These were established by Imperial Edict
199 in Taisho 12 [1913].

The two classes are signified with the two highest
celestial stems, pronounced kou and otsu (less
commonly
kinoe and kinoto) in Japanese. The former is the higher class.
