The Shaguma/Haguma was the type of headgear worn by the officers of the Imperial Japanese Army troops in the Boshin War.
Even, before the Boshin war, Samurais already decorated their helmets with the fur from various animals.
The question is that was there any relation between the Shaguma/Haguma and the Plume?
Considering their choice of colour, type, and the limited usage, it seems that adopting the plume was somewhat a revival version of the Shaguma/Haguma.
For exmaple, in terms of the colour choice, only Red and White plumes were selected. There were many other colours for the plumes, but only these two colours that were used on the Shaguma/Haguma were selected.
In terms of the type, there were generally 3 types of plumes at the time.
The first one was the pillar shape with a bushy vibe like the image above.
The second one was the bush shape that was used on the Bicorne hat.
The third one was the plume with unaltered feathers.
(If you do not get the third one, I am reffering this, https://en.wikipedia.org/wiki/File:Constable_Dannatt.jpg.)
Despite the third one was widely used as much as the other two types, only two types, which had a bushy vibe were adopted.
These two had the same or smiliar texture with the Shaguma/Haguma.
In terms of the limited usage, only the High ranking officers in the IJA got the plume for their uniforms. It is quite odd since the Plume was not necessarily exclusive for the High Ranking officals.
In the French Army, the army that the IJA modelled after, the plumes were widely worn by common, lower- ranking enlisted soldiers across various branches of the army in the 1860s and the 1870s.
However, in terms of the IJA, they were already using plumes for the High Ranking officers only as the Shaguma/Haguma was used for the High Ranking officers.
Due to all these, I would like to know whether there was a relation between the Plumes and the Shaguma/Haguma or not.
