As Osaka, an economic city called the 'kitchen of Japan,' was in good health, Edo succeeded in attracting many wealthy people by Sankinkotai system (a daimyo's alternate-year residence in Edo) and became a major consumer area in Edo period, and after changing its name to Tokyo, established a centralized administrative framework, and came to collect more wealth by taxes and foreign trade.
「天下の台所」と呼ばれた経済都市の大阪は健在であったが、江戸期以来参勤交代で富裕層の集住に成功して大消費地となった江戸が、東京となって中央集権体制を確立し、税と外貿で富を更に集めるようになった。
