Bayonet Arts Badges
Bayonet Fighting Skills badges with original paper case.

The central design on the two badges are the same: rising sun,
cherry blossom, rifle with bayonet, and stylized waves--all
contained within a sacred mirror outline.

The large badge also has a border of sacred jewels

The case reads 'Qualification Badge. Great Japan Bayonet
Fighting Skills Promotion Association.' This association was
established in 1941, so the badges date from 1941-45. (In 1945
all martial arts were banned by SCAP.) Since the larger badge
has a hollowed-out reverse (for lack of a better term), it is most
likely later than the 1942 badge you can see below.

The two badges have identical inscriptions: 'Bayonet Fighting
Skills.' I am not sure if both badges came in this one case, or if
the case was used for just one of these badges.
Although there is no inscription indicating
bayonet fighting, the rifles here have balls
on the end, which were used during practice.

Scarce 1942 badge. Inscribed 'Bayonet Skills. Jukendo [Bayonet
Skills, Student Group. Official Instructor's Badge. Showa 17
[1942]. Number 361.'

Note that part of the date and the badge number have been
punched in.
The design has a kanji for ‘Prize’ at the top so we know this is an award of some sort. The center design has a kendo (Japanese
swordfighting) mask, but neither of the two figures behind it are swords. One is a rifle and another is a rifle shape with a
circular object on the tip. This indicates that the skills practiced here are not swordfighting skills but bayonet skills.

The figure below the mask is the insignia for the Manchuria Railroad Defense Unit. Two crossed rifles superimposed on a rail.
These were IJA units stationed in Manchuria and assigned to defend the railways.

The reverse is rather plain, having just an inscription. It reads ‘Kantou-shou, Yanji [City], Moribe Unit.’  (Moribe is a family name
and designates the commander of a unit.) The place name is the Japanese reading of a Manchukuo province that of course no
longer exists. Now the area is called Yanbian Korean Autonomous Prefecture, and though located in China is mostly populated
with Koreans.

So this badge was given to a winner in a bayonet fighting competition held within the Moribe Unit, or perhaps the competition
was between different units and the Moribe Unit gained a prize, each contributing member receiving a badge.
Kendo (sword) and jukendo (bayonet) tournament
award badge given by the 49th Infantry Regiment.
Hallmarked sterling silver.

Inscribed 'Award. Imperial Military Reservist
Association. Ibaraki Prefecture [??] District.
[3 names of villages?]  General Athletic Meet.'
