Answer:
One possible reason that similar systems of feudalism emerged in both Europe and Japan although they had little contact is that were becoming more advanced and developed and so people began to want more and become intent on having the most power so people like lords and daimyos were created so more people could have some sort of power.
Professional warriors were important in both societies because feudalism is a system of government in which local lords controlled their own lands but owed military service and other support to a different, more powerful lord. Local lords or daimyo owed military service as a payment for the right control their land, this made professional warriors have a lot of value to the lords/daimyo. These professional warriors were not only protecting the lord’s/daimyo’s lands, but they are acting as payment and the very foundation of the whole system of government called feudalism.
