It can be said that in order to understand the actual power of domains, comprehensive judgment is required based on whether there are good ports or mines, the distance of Sankinkotai (a system under which feudal lords in the Edo period were required to spend every other year in residence in Edo), tax collection according to the development of commerce, and so on.
良港の有無・鉱山の有無・江戸までの参勤交代の距離、商業の発達に伴う税の徴収などを総合的に判断しないと、諸藩の実際の実力は、把握できないと云える。
