Military Merit badge (Army)
Damaged badge, which allows the construction to be seen.
This is called the NCO Attendant’s Badge in most English sources. The Japanese title for
labor in this sense may also be translated as ‘merit’ since this badge was awarded to NCOs
who had served 6 or more years without a major blemish on their records.

It was established in either Meiji 37 [1904] or Meiji 41 [1908], according to two different
Japanese sources I found. Peterson’s English language book shows the badge but doesn’t
give any dates.
You can see that they are slightly different in color, both the center
blossom and the branches. Since there was only one version of this
badge, this difference was the result of having different manufacturers.
The reverses of these two have different shaped pins as well:
Most badges you will see have the wider pin (left) without an inscription.
This inscription identifies the maker : Made by Wada Hiko, Osaka.
