In ancient days or medieval ages, the Japanese military followed a different classification or structural organization as compared to the modern military hierarchy. These were the times when the Japanese military followed a Feudal hierarchy system according to which the ranks were based on the levels of power and talent.
This organization structure or hierarchy helped in the proper division of responsibilities and duties and was a strict division that ensures smooth functioning of the military. If you wish to understand this hierarchy, you can go through the following given information on the Ancient Japanese military hierarchy.
The King or the Emperor
Traditionally, the emperor or the king was the highest power in the ancient Japanese military organization or structure. It is true that the Shoguns practically possessed hold over the entire Japanese feudal military but it is was the emperor whose orders were followed and no one could speak against him. Shoguns used to consult the king for every matter related to Japanese military and hence his word was the final.
As far as handling the military from the front and in an in-depth way was concerned, it was the Shoguns who were the true military rulers in the country. It was their responsibility to take care of the country and also all the civilians. If this rank was to be compared with modern military ranks, then it is the General of the Military who would be considered at par. They were liable to answer only to the emperor and were responsible for handling each aspect of defence and attacks etc.
The next rank in the ancient Japanese military hierarchy was that of the Daimyo. The Daimyo were also referred to as the warlords and reported directly to the Shoguns. Their responsibility was to obey any orders given by the Shoguns and make sure they were implemented thoroughly. There were different Daimyos for different regions or areas and each was responsible for handling that district.
The army of Daimyo was made up of elite warriors who were known as the Samurai, a term which is very popular even till today. The samurai were the soldiers of immense talent and power. They not only represented their country in the battlefield but enjoyed many privileges with superior social status. A Samurai in ancient Japanese days was considered to bring Honour to his family by his service to the country or kingdom. They worked on the instructions or orders of the Daimyo and were expected to be very disciplined.
The nobility court was not actually the military personnel in ancient japan but comprised of the court of justice. They had little power but were related to the royal family in those days.
This is the lowest level in the ancient Japanese military hierarchy and is comprised of soldiers who served the Samurais in their troops. Those elite soldiers who showed exceptional skills and talent were promoted to the Samurai level.
