Tankō

The ''tankō'' is the first uniquely definable type of Japanese armor. Other types that were used earlier such as ''Jòdai no Katchù'' (ancient armor, as described by armor historian Suenaga Masao) have been mentioned, but are not entirely verifiable.
The ''tankō'' was made of sheet iron and
tanned leather, laced at the hips to conform to the wearer's body. The leather served as a support for the iron sheets, and as a protective
lining meant to prevent damage to the wearer's clothing and skin. The iron sheets were formed into strips that were
riveted side-by-side or overlapping. The carapace was built higher than the breastplate in order to provide protection for the neck. The front side had an opening that could be closed once the armor was put on. The armor was attached to the body via fabric bands that ran over the shoulders.
Keikō
Another Japanese armor type from the Kofun period, the ''keikō'' ("hanging armor"). The type was also used in Japan as armor for mounted forces as the use of cavalry in warfare increased in importance.
[William Wayne Farris: ''Sacred texts and buried treasures.'' 1998, S. 76.]
The difference between the ''tankō'' and ''keikō'' lies in the upper chest area of the armor, which in the ''keikō'' variant included a protective sheath of iron bands. The lower portion of both types consisted of overlapping iron
lammellae. The use of leather underpinnings was also used by both forms. The bands were fixed together through riveting or the use of leather straps.
Helmet

The helmets (''mabisashi'') worn with the ''tankō'' armor type are known in two versions. The first type (
jap. Kondu Maruhachi) consisted of sheets of overlapping iron similar to the ''tankō'' chest piece). Lamella pieces were riveted to horizontally lying bands to create a dome shape for the helmet. A short eye shield was attached to the front, which was often pierced with holes. A small hump with a fixing pin for a crest lied at the top of the helmet's dome.

The second type was created differently, with horizontal and vertical bands throughout the helm's dome. The eye shield and attachment for the crest were much larger. The attachment also included a shell-like form that served to further fasten and accentuate the crest.
Shield
The shield worn with this type of armor was made of sheet iron fixed to a wooden base. The shield's components were fixed to each other and the shield's body through the use of riveting. The exterior has a slightly convex shape, and was decorated with triangular and linear patterns.

in origin. In the sacrificial book of
Tōdai-ji from 756 ''tankō'' and ''keikō'' are listed as gifts. These terms were then assigned to varying types of excavated armor.
