Abstract: Hirobumi investigated the Reform Movement of 1898. He hoped that the constitutionalism system be established in the Qing Dynasty by reform which was orderly and gradual and not Anxiousaggressive. On the other hand, He realized that it was difficult for the Qing Dynasty to get rid of the longstanding corrupt practices in short time. The Qing Dynasty lost the opportunity to reform. The topdown political reform was difficult to succeed for the Qing Dynasty which government was decadent and surrounded by powers who wanted to divide it. The constitutional movement in the Late Qing Dynasty made it clear that the reform for constitutionalism system may result in domestic turmoil or revolution. It would not only overturn the Qing regime but also affect Japan to change.
